1804.	Solve : Creating weebly app?
Answer» HI, we are trying to create a website for our company which needs a demand page. The page would CONTAIN a form which the customer has to fill in like name, email or phone NUMBER, and the link of the item they want us to purchase for them. We don't mind using Godaddy, or weebly. But they don't have the service of sending a confirmation email or message to the customer to NOTIFY them of their submission, and also send a unique number of their order. Now as I searched around, only the option of creating our own app would work. My question, if you guys can help, is what do I require to create this app (I have some programming skills and web design knowledge)? Also anyone knows of a hosting service that has that feature? I understand that we will need a DB and java CODING. Also, can't we use yahoo mail to generate this email? Thank you. Note: no, customers in our country can't purchase things online, so our company would purchase the item for them and then deliver it.

Looking at the shell script, maybe its correct, but my eyes are picking up on syntax/typo issues possibly. However because I dont code in Linux shell environment maybe its correct.

1809.	Solve : Batch execution question?
Answer» I have a number of NAS disks attached to my windows 10 desktop. For some strange reason, some of them go offline. I have a batch file to re-connect them, issuing "Net Use" commands. If I click on the file "Upnet,bat" I just get a flash of the command prompt window and no results. If I open the editor on the same file and use cntrl-a, cntrl-c then open a command prompt window and paste the results into the command prompt window, it works fine. This two-step process is fine for the task but I was wondering how to get it to run with a one click on the shortcut to the batch file. Thanks [attachment deleted by admin to conserve space]If you want to see the results use the PAUSE command at the end of your batch file.I had a PROBLEM with Buffalo NAS drives going to sleep on us and this was breaking mapped drives for users. My solution was to have an automated routine that every 15 minutes would as I called it "TICKLE" the NAS to keep it awake. I had a batch that ran with a 15 minute delay and it would transfer a small text file from the NAS to the server that was keeping the DRIVE awake. I used SLEEP to have 15 minute delay and a goto loop in the batch file to have it xcopy the file from a specific DIRECTORY of each NAS drive over the network and then a clean up process that would delete the very small less than 1KB file after it was transferred, this way every iteration at 15 min intervals caused it to work the NAS storage systems that we had and problem solved. I contacted Buffalo about this and they didn't have a CURE for the sleep state issue that their NAS drives had. We had about $8000 worth of NAS devices and couldn't return them, so this was the quick band aid to keep them from going into a sleep state and causing users with mapped drives to the NAS drives to break. I guess this is one of the problems with buying Green Power Efficient NAS drives that shut off, put the drives in sleep state not spinning and then spin back up when needed. If this is the case with the NAS Sleep State then this could be a valid fix for your site as well.

1810.	Solve : C++ IDE Suggestion??
Answer» Looking for a replacement C++ IDE other than Microsoft Visual C++ \ Express. My history of IDE's for programming in C++ are: Borland C++ 4.02 (VC6) MS Visual C++ 6.0 BloodShed Dev 5.0 I tried out Netbeans C++ IDE on a healthy Windows 7 64-bit system and when compiling good code it fails and the debug output is just about worthless. Going into Debug it gives options to configure the debugger as if the IDE is not ready after installation to just code something up and be able to compile and debug it right away as I guess I was spoiled with in all prior IDEs I have ever used to have a functional and very valuable debugger right at the get go and netbeans lacks that or isnt user friendly... https://netbeans.org/features/cpp/index.html I liked BloodShed Dev C++ 5.0, BUT it has so many bugs and some bugs are causing grammatically and syntax correct code to compile successfully but completely malfunction such as within a while loop of recent code each iteration of the loop flips a value between 0 and 1 and back to 0 again in a flipflop, and the value starts at 0 as the integer is initialized before the loop and then the variable++; increments by 1 to value of 1, it runs an IF STATEMENT that if the variable is = 1 run a process different than if the variable was 0 and before exiting the IF logic to set the value back to 0 so the next iteration of the loop the value is now 0 and so it does the other logic for if the value is not equal to 1. The value gets stuck at 1 so it runs as 0111111111 instead of 0101010101. I dug out of storage my old Borland 4.02 and opened my CPP project and compiled it without any issues, ran the program and it runs correctly with 0101010101 so there is an issue with Bloodshed Dev C++ 5.0 in that the compile result from the source code is flawed and so it must be a bug that I ran into with it. I dont want to go back to using Borland 4.02 on my old Windows XP system because it is so out of date. So looking for a modern IDE that will work the same as Borland 4.02, VC6, and Bloodshed Dev C++ 5. Reason for avoiding Microsoft Visual C++ Express is 2 reasons... #1 - I want to use one that is FREE that is completely FREE and so I have all Dev Features as well as no restrictions of HOME vs Corporate Use #2 - Might be nonsense, but I dont want to program based around MS VC++ because I want my source code to be less dependent on Microsoft and more flexible cross platform into Linux etc. I guess I am saying that I dont want to have a SITUATION where I paint myself into a corner with programming for Windows if MS VC++ uses Windows ONLY libraries etc. Sure I could always run it through Linux in a WINE environment, but I just want to avoid the potential to paint myself into a corner by creating more universal non OS platform specific code. (* I also have never programmed in C++ before for Linux but would like to and so you might see something in this part that I am wrong about and maybe I dont have to worry about MS VC++ created code migrating to Linux OS use. ) ** I feel the issue with #2 is because back in the day with Borland C++ 4.02 my code was proper for Borland and compiled and ran with no issues, and yet with VC6 I would get compile errors until I tweaked the code to be to VC6 syntax such as i had to be specific with VC6 to specify #INCLUDE on one of them and the other wanted it as #INCLUDE without the .h . Quick search online shows that .h use is depreciated. http://stackoverflow.com/questions/2976477/difference-between-iostream-and-iostream-h so I guess as standards came to be and Borland 4.02 is before many standards of today that would be why that is that issue between them however I have a feeling that that latest Visual C++ IDE has features that are not cross platform friendly for OS and so i am trying to avoid getting snagged if there is a snag into programming only for around MS Windows and trying to remain universal if at all possible. Visual Studio Express is 4 years old. They re-branded the Express editions to Community Editions. #1 is now irrelevant because the Community Edition is free for both personal and corporate use and furthermore is identical to the Professional Edition. It's only limitation is that it cannot be used in ENTERPRISE environments. (Well it can, but it would break the license). Most Open Source C++ software uses Microsoft Visual C++ for building their Windows Binaries. Avoiding MS-specific extensions is fairly easy. You can change compiler options to use g++ to avoid language extensions (or, know how to recognize them), and bind to GTK or TCL/TK or some other cross-platform toolkit if you make any User-Interface software. Thanks BC ... gonna give the Community Edition a try. Surprised the ISO is 7.1GB https://www.visualstudio.com/downloads/

1811.	Solve : Command Line?
Answer» Hello, I had ONE of my class substituted with my current class which focuses on command line.....I have zero clue about this type of stuff can ANYONE help with some lab QUESTIONS? 1.Navigate to the user account home directory. Use the command line to create a file named test.txt with the text “HI I AM A TEST FILE”. Output the contents of the file using a command line program to verify that the file contains what it should. I deleted the duplicate threads. Please only post once. Thanks.We aren't going to do your work for you by simply giving the exact commands to run. Instead I'll give you hints and let you work the rest out. Break the instructions into chunks, each will map to one command: Navigate to the user's home directory To change directory you should use the "cd" command, you can find the man page for it here: http://linuxcommand.org/lc3_man_pages/cdh.html I'll leave you to figure out how to get the home directory (hint, that page explains it if you read carefully enough) Use the command line to create a file named test.txt with the text “HI I AM A TEST FILE” If you use the "echo" command such as: Code: [Select]echo “HI I AM A TEST FILE”You will see that it will print the message to the screen, this is known as stdout. You can then "redirect" the contents of stdout to a file which is explained here: http://www.cyberciti.biz/faq/bash-script-output Output the contents of the file using a command line program to verify that the file contains what it should. For this you would use the "cat" command: http://linux.die.net/man/1/cat I'd strongly recommend learning more about the command line as once you master it it can be a lot easier and faster to use than using a regular file browser. For example, if you want to batch rename a bunch of files or even search a bunch of text files for a word and store the names of the files that contain it in another file, you can do it with a single command rather than having to manually do it with the graphical interface or find a THIRD PARTY program to do what you need. Nowadays I don't even have a file browser installed on my system, I can do all file browsing/manipulation through the command line. Just force yourself to use it more and you'll soon figure it out.

In addition to the languages provided by Microsoft, there are many alternative languages that target the .NET Platform, including: COBOL for Microsoft .NET. Perl for Microsoft .NET. Eiffel for Microsoft .NET. Python for Microsoft .NET. Pascal for Microsoft .NET. Mercury for Microsoft .NET. Mondrian for Microsoft .NET. Oberon for Microsoft .NET. Salford FTN95 (Fortran) for Microsoft .NET. SmallTalk for Microsoft .NET. Standard ML for Microsoft .NET. Dyalog APL for Microsoft .NET. Notice there is an implementation of Perl. This is not new information, But many are not aware of how people are using Visual Studio to do unusual things. It's interesting that the very first comment there does precisely what Raymond Chen says, and starts slagging off Visual Basic developers! I think the comparison falls apart somewhat after .NET, though. With earlier versions of Visual Basic and the comparable tooling it was PRETTY cut and dried that Visual Basic was much faster- it was pretty much called a Rapid Application Development tool, after all. But once we jump to Visual Basic .NET I'm not entirely sure the analogy continues, or if it does it isn't really restricted to Visual Basic, as the "RAD" element applies to almost all .NET languages. I'd argue that the looked-down-upon technology that contributes to fast development of GUI programs on Windows could probably be Windows Forms. It's very poorly regarded because it doesn't properly fellate enterprisey developer methodologies. Fitting into the idea, though, I have a Command-line tool that is about 8 years old now that I use regularly for evaluating math expressions at the Windows command line. It's hardly the only program that does it but I sometimes make use of features like lists and sets whereas most other tools of the same sort are restricted to more standard arithmetic. At any rate, I wrote it in Visual Basic 6 and haven't bothered to replace it. I did rewrite it but I simply don't trust the new version even if it does pass all the unit tests. No unit test can replace 8 years of reliable results, after all.

Microsoft partners with many companies to bring their languages to the .NET Platform. In addition to the languages provided by Microsoft, there are many alternative languages that target the .NET Platform, including:
COBOL for Microsoft .NET.
Perl for Microsoft .NET.
Eiffel for Microsoft .NET.
Python for Microsoft .NET.
Pascal for Microsoft .NET.
Mercury for Microsoft .NET.
Mondrian for Microsoft .NET.
Oberon for Microsoft .NET.
Salford FTN95 (Fortran) for Microsoft .NET.
SmallTalk for Microsoft .NET.
Standard ML for Microsoft .NET.
Dyalog APL for Microsoft .NET.

Notice there is an implementation of Perl.
This is not new information, But many are not aware of how people are using Visual Studio to do unusual things.

It's interesting that the very first comment there does precisely what Raymond Chen says, and starts slagging off Visual Basic developers!

I think the comparison falls apart somewhat after .NET, though. With earlier versions of Visual Basic and the comparable tooling it was PRETTY cut and dried that Visual Basic was much faster- it was pretty much called a Rapid Application Development tool, after all. But once we jump to Visual Basic .NET I'm not entirely sure the analogy continues, or if it does it isn't really restricted to Visual Basic, as the "RAD" element applies to almost all .NET languages. I'd argue that the looked-down-upon technology that contributes to fast development of GUI programs on Windows could probably be Windows Forms. It's very poorly regarded because it doesn't properly fellate enterprisey developer methodologies.

Fitting into the idea, though, I have a Command-line tool that is about 8 years old now that I use regularly for evaluating math expressions at the Windows command line. It's hardly the only program that does it but I sometimes make use of features like lists and sets whereas most other tools of the same sort are restricted to more standard arithmetic. At any rate, I wrote it in Visual Basic 6 and haven't bothered to replace it. I did rewrite it but I simply don't trust the new version even if it does pass all the unit tests. No unit test can replace 8 years of reliable results, after all.

1817.	Solve : What language should I use??
Answer» I want to build a front end desktop application that will be able to start Windows applications within it, it needs to be able to manipulate file structures. Any ideas?So you want a GUI shell wrapped around Windows so the user doesnt use the Windows GUI but your own? C++ would be able to do this. Its quite the project though. LOTS of programming! You would be working with OpenGL probably for your rendering of the GUI. http://www.opengl-tutorial.org/ If wrapped around Windows, it would be part of the startup and so the user would see Windows logo and Windows booting up, and as soon as the startup path triggers, your program would take over full control of the GUI. Is this what your looking for or are you trying to hide Windows completely, but base it around Windows? Your also going to be likely tapping into API calls to Windows. http://www.dreamincode.net/forums/topic/207581-intro-to-the-windows-api/ If you dont want to hide the Windows GUI environment the programming would come much easier running your program within a Window with Windows Desktop GUI not hidden. You then wouldnt be having to mess with OpenGL and able to use the IDE such as Visual C++ Studio Express 2013 https://www.microsoft.com/en-us/download/details.aspx?id=44914 in which you can build the layout and add BUTTONS and text boxes and have your code tied to buttons to perform specific tasks as well as information typed into a text box could be part of a search function etc. Have you programmed in any other languages before or is programming new to you? (This project may be way far and above anything you ever imagined in complexity and time needed to program it all. Not to scare you away, but just the facts. ) My programming in C++ is usually short and sweet programs which sometimes can take a week to create. They are generally less than 20 pages of 8.5x11 when code is printed out. I am not a master of C++ but also not new to it. I took 3 YEARS in college on it ( Intro C++, Intermediate C++, Advanced C++ ) and I dabble in it as a hobby to make small programs to solve needs I have. I started programming in the 1980s with Basic and then dabbled in QBasic, then C, then Visual Basic in the mid 90s, and then took C++ in college because it was considered the harder language not bound to just the Windows platform and C++ would help me better in my career path in which back in the late 1990s I wanted to GET into making Video games and mastering C++ was the ticket to that. However getting into it, I soon REALIZED why game manufacturers have teams of master programmers and graphic artists and computer/network engineers. A game I wanted to make as a project in college that was going to be on the lines of Quake like graphics i was dreaming up I soon realized I dont have the time and knowledge to make this happen before the semester is over, so the game I created called Moon Escape which was a linear progression game of choices, the graphics were that of something you would see on a Shareware DOS title of the 1980s with bitmap manipulation of if the person bushes a button, then load up this next bitmap that shows the change as a result of pushing the button. I got a A+ on my project, but it was almost embarassing showing this very CRUDE game to the class, standing up there with the game shown on the projector on the wall, and another older glass platen projector with code on it to show the class what I used for code and how it affected the game. The professor was very good and didnt say you are crazy to take on such a project, you would sink or swim, and you would know you bit off more than you can chew and adjust and learn from it.It would help if you could explain what you are trying to do in more detail. For Windows your best bet would probably be using .NET with a language like C# or Visual Basic. The free versions of Visual Studio would be good for this. Doing it in raw C++ seems like it would just overcomplicate the issue.What do you mean by "start Windows applications within it"? Do you mean that it will launch other applications or that those applications will need to somehow be "integrated" into the same program? For example- having multiple programs launch and somehow appear as "tabs" in your program? "it needs to be able to manipulate file structures" is rather vague. Pretty much all software needs to "manipulate file structures" so I suspect you have more specific "file structures" in mind. If you just want a launcher interface, that is reasonably straightforward. Most programming languages expose ways of starting and even monitoring launched processes. In the latter case, where they need to be integrated, that's not reasonably possible without being responsible for the applications themselves and designing them with the "launcher" in mind- eg being a Control or DLL that is interfaced with the Menu/launcher. Tomwatts, What they say is true. Learning a formal computer programming method is not an easy task for anyone. It takes years of work and the help of others to become skilled.

Regards,First of all, why? UNLESS your idea is somehow much better than the other crowd funding sites out there then there is no point. To answer your question- you will need good programming ability in both JAVASCRIPT and some sort of backend language such as Python, PHP or Ruby. You will also need very good Database knowledge and knowledge about writing a secure site, particularly since you are dealing with real money. HTML and CSS ALONE are nowhere near enough to do what you are planning to do. Don't go using a random WordPress plugin... That way there is no way your site is going to be unique and blindly using a plugin for your entire site WITHOUT the technical knowledge of how it works is just setting yourself up for trouble.

[attachment deleted by admin to conserve space]Please STOP posting links and asking us to go see what you did. Cut and paste into this thread.Not sure what you are trying to do in line 55. You're comparing the $post_id variable to the string of "comment_id".

At the moment you aren't storing which post each comment relates to in the database, it is impossible to do what you are trying to do with your current database schema. You need to change your database schema so the comment table has a post_id column then update the INSERT query to include the ID of the post that the comment relates to then update the query that gets the comments and add a WHERE clause to only get comments where the post_id column is the same as the current post ID.

Please stop posting links and asking us to go see what you did. Cut and paste into this thread.

To be fair it was me that suggested using pastebin. I prefer it as it gives line numbers/syntax highlighting and stops the thread getting full of massive blocks of code. However, if using code tags are preferred on here then that's fine.line 55 it was worth trying.... it tends to duplicate every comment in my database

let me work on that.. cause you're the second one telling me to do that!!... ill keep you posted it works

...My bad about pastebin linksI failed man... I would be glad if you send me some scripts that I need to work with....

1821.	Solve : Coding Test Ransomware Help?
Answer» Greetings, I am doing a project for school and I am making a test RANSOM ware. I have the form itself done in visual BASIC but I have questions on how to PERFECT it. What do I add to let them be able to pay and then get their decryption key, and how do I add something that ENCRYPTS all files and the only way to be decrypted is with a key. I'm making this in Visual Basic, if you could also tell me how to do the same thing but like in an inclosable browser session that would be great.Really? I mean really?

1828.	Solve : Convert symbol-file to text-file?
Answer» Hi everyone, I'm really newbie in this thing. Currently I'm using an engineering software and the output files from that software need to be converted into another software in order the results to be display in 3D format. So there's no problem for that. But the challenge was I need to look what is inside the output files. It suppose to be in coding format (I'm not sure what types of coding been used). When I tried to open the file using text file (Notepad, Notepad++, Wordpad, Word etc...), it was in symbol-format so that I can't understand it (refer to attached file for example). Is there any ways/tools that I can use to convert the file so that it can be readable? Thanks in advance. [attachment deleted by admin to conserve space]Perhaps you need to understand the disquisition of "code" and script. A code MAY not always make sense. A script is CLOSER to how people read and write. A script is something done by human hand or can be read by the human. But code is code. It is a set of values meaningful to a machine or device. Or maybe readable by a human. If you want to 'see' code, you need an editor that will present code in a form that means something to the human eye. Notepad, Word and other such tools do not represent all codes. Only those codes used for word processing. Perhaps what you expect is an editor that converts the output into a script. Some professional programmers sometimes wish to look at the raw code and see the actual output, even if it does not make sense. To make it readable, the human may ask to see the code in hexadecimal format. one byte at a time. Example. A man wrote a program called TEST.COM and wants to see the raw code. Using a PC, he gives this command at the command prompt. Code: [Select]D:\BIN>debug test.com -d 13BF:0100 B4 01 CD 21 88 C2 88 D6-52 51 B4 02 CD 21 59 5A ...!....RQ.. 13BF:0110 88 D0 FE C2 41 3C 5A 90-75 EE 90 B8 00 4C 88 E8 ....A<Z.u... 13BF:0120 CD 21 90 5A 90 76 76 76-76 76 76 76 76 76 76 76 .!.Z.vvvvvvv The part above, the human typed "debug test.com" followed by enter ant then the letter "d" followed by enter. The rest is from the computer screen. (The debug program was once used in Windows programming.) In this case, the code does not make much sense. But at least it does represent the output in a form the man can see. The example above is typical for the hexadecimal representation. If need be, the human could alter the code and SAVE it. Thanks for the comment... Yes I'm sorry for my misunderstanding about the 'code' and 'script' since I'm not in this area. So if I'm not mistaken, the problem is I tried to read the output files using Notepad, MS Word etc...which will display in funny characters. So do I need an editor to open the output files so that it will be in readable format? Any suggestion on specific editor? The problem is that it is a binary file format. Given I can find no information based on the "Drop Velocity" part of what I WOULD expect to be the header, and you didn't mention any names for the software that created it, or any file formats that it could be, I suspect it is a proprietary and poorly documented file format which isn't uncommon for those sorts of programs.Just to update about this problem... Actually I just tried to CHANGE in "save as" option into the text format and it works...!!! Maybe I was misslook at this option before. Anyway, thanks for your comments and advices here. Really appreciate it. Thanks...!!

Solve : help== Was not expected at this time (Batch)?

Answer»

Ok, Hi! This is my first topic here, so I will go to the point directly:
I have this Batch FILE:
---------------------------------------------------------------------------------------

@echo off
:checkstage
IF "%0"=="%0" goto comparch
IF "%1" == "help" goto 1
IF "%1"=="emulate" goto 2
IF %2== goto 3

:comparch
echo Comparch v1.0
echo 2015 (C) uSoft. All Rights Reserved.
cd..
call shell.bat

:1
echo Usage Description
echo ===== ===========
echo comparch help Displays help about commands
echo comparch emulate [file] Displays help about commands
cd..
call shell.bat

---------------------------------------------------------------------------------------

That file is called by another batch file, shell.bat.
And it is like this:

---------------------------------------------------------------------------------------

@echo off
title Comparch v1.0 Shell
:shell
cd bin
set/P cli= *

IF %cli%==comparch call comparch.bat

---------------------------------------------------------------------------------------

So, my problem is that when I type, for example, comparch help, it displays:

help== was not expected at this time

And it leaves instantly.

What is wrong?

Pd: When I type "comparch" alone without any parameters, it runs correctly...Look at your test for %2TO clarify

This line:

IF %2== goto 3

will break the script if there is no second parameter passed to the script (if %2 is empty when the script is RUN) This is because you must have something on both sides of the == in an IF test. The usual way to beat this is to use quotes like this

IF "%2"=="" goto 3

Also,

When this line is run:

set/p cli= *

However if the user just hits ENTER so set /p captures an empty string, then this line:

IF %cli%==comparch call comparch.bat

will break the script because %cli% will be empty so do this:

IF "%cli%"=="comparch" call comparch.bat

This will fail if the user types the answer using any upper case characters. I am sure you can find out how to get around this, if the boast in your sig is true.

Finally, what is this line supposed to do?

IF "%0"=="%0" goto comparch
Thank you, and... "%0==%0" It was 2 AM, I didn't even wanted to think anymoreQuote from: BatchProgrammer on October 29, 2015, 04:02:49 PM

1831.	Solve : Black Debug Screen?
Answer» I am trying to write a C program but every time I run the debugger all I get is a black screen. Personally I am not sure what's wrong, but would appreciate any help. The debugger is Visual Studio 2010 on Windows 10. Code: [Select]#include&LT;stdio.h> #include<stdlib.h> void main() { int num; int i,j,k; int grd[20]; for(i=0;i<20;i++) { grd[i]=5+rand()%(100-5)+1; } for(k=0;k<20;k++) { num=grd[i]/5; printf(" %d : ",grd[i]); for(j=0;j<num;j++) printf("X"); printf("\n"); } } Is it only this program that the debugger goes out to LUNCH with? Have you tried a simple program to see if it also has issues and then add an intentional typo to see if the debugger works Code Below should execute and show Hello World!. You might have to add a system pause or an input statement to avoid it running and EXITING the console. Code: [Select]#include <iostream> int main() { std::cout << "Hello World!" << std::endl; return 0; } Code Below is missing ; in 2 locations and debugger should point them out on the lines Code: [Select]#include <iostream> int main() { std::cout << "Hello World!" << std::endl return 0 }

1833.	Solve : bat volume settings?
Answer» Hello, I just wana know how to make bat file that can unmute and turn volume on maximum on windows 8. What commands should I use? ThanksYou would need a 3rd party piece of software and have a MACRO that either performed a hot key combination if laptop it might have a Fn key combination to increase volume, if s desktop you would need someone elses program that calls to the windows audio configuration through an API call I would think. I am forwarding this to the attention of a programmer who wrote some code a while back that might be of help to you on this. I had a situation where I wanted to have my audio muted for my user account because others on the computer when logging on would set the volume to max and shut off my mute. I would log on after them and have to mute it again. The audio levels are shared among all windows USERS vs user preference per profile, and so you inherit the last logons audio properties even from a different user account. It was frustrating and the work around for me was to shut off the SPEAKERS so audio was off before logging on. Then if I want audio I turn them on. Still this has me and other users fighting it out behind the scenes to where one PERSON is having to turn speakers on and I am having to turn them off. So the power button to speakers is likely to wear or break from daily on and off power to them. The programmer wrote some code that worked with an API for the windows sound audio level. Possible answer. There is a script for auto hotkey. http://stackoverflow.com/questions/16290463/can-i-make-a-script-for-a-macro-to-change-volume But I do not personally know if it works. Quote I am forwarding this to the attention of a programmer who wrote some code a while back that might be of help to you on this. Slapping the Windows Master Volume Project is on github.

If you can use 3rd party apps, with the invaluable (British) NirCMD you can at the prompt or in a batch script, mute the volume, set it to max, and set it to any level between 0 and 65535. And lots of other things, not just sound related. http://www.nirsoft.net/utils/nircmd.html You can have the system tray volume control slider visible and make it jump up and down from a command prompt.

1841.	Solve : Learn Objective C on an OSX virtual box??
Answer» Hey friends, I have decided to take up coding in objective C. My mac is a bit outdated and I really would prefer not to purchase another one at this point ESPECIALLY since they charge so much for flash memory and allow no upgrades. I really despise that. Anyway, my PC's are really great and I would like to know if it is possible to learn how to code on a hackintosh or unbuntu running an OSX virtual box, or if the downsides would warrant purchasing another mac. If it looks like I need a new mac, what would you recommend for BEST bang for buck? I have my PC's for raw power so this purchase would be used exclusively for coding. THANKS! RobHere are some observations made on my personal experience. I have worked as a professional programmer years ago. Since then my interest in the PC has been just personal for my own USE. My feeling is that if I wish to learn something new, I do not put out any money unless it is absolutely necessary. The exception would be if somebody pays me in advance for project, then I'm willing to shell out some money. Otherwise, for my own educational needs, I make use of all the free stuff that's now available over the Internet. You can find many good tutorials on the Internet about objective C and similar programs. One of the most important skills you need as a programmer is the ability to read somebody else's tutorial and understand what they're getting at. Of course, hands on experience is very important.. Yet you have to read the tutorials to understand what something really does. And there are lots of tutorials. There is a bit of mystique about programs and hardware that Apple produces. I understand that. That is part of their cult, loops, I meant to say market strategy. They promote the idea that their stuff is better and maybe a little bit more sophisticated than the average person can take. And yes, I really do like Apple products that I have had in the past. But I could not afford to keep using them. Another avenue of approach might be to consider alternatives to Objective-C. You can Google this key phrase and see what you come up with: alternatives to objective C. In my opinion, this would be easy to set up on a PC then going the virtual machine route. Furthermore, the alternatives to Objective-C are either freeware or shareware and don't cost a thing. If you get to the point where you actually have a usable program that she would like to distribute in the Apple Store, you could just fire up your old Mac and test the program out on it. When developing programs usually speed of the processor is not really a critical issue, unless you're trying to debug a very large file. Just simple editing and compiling should not take up a lot of time. If you find your projects tend to be time-consuming, you might want to reconsider making your program more granular. More granular means that the program is a little modules that can be compiled and tested by themselves in the debugger that once you have a large part of your program debug and tested, you can make that into a library and any further testing and developing you do justly sent to the library you already created. I suppose you already know that, but I'm surprised at how many people start out in computer programming don't understand some of the traditional tools that have been used to speed development. One of the things is the idea of divide and conquer. If you can divide up your project in a separate little pieces, and actually goes faster and easier than what you might think. Anyhow, that's my opinion. But I do believe it is based on years of practical experience. end of dictation Wow thanks for that reply. I will do what I can to find an older version of Xcode that actually runs on my old macbook. I will also look into alternatives. I suppose the reason I was thinking about going the xcode route is because my friend gave me a highly acclaimed book on it that I wanted to use. Unfortunately, its almost entirely from a mac, xcode perspective. I am very new to coding, with only one introductory computer SCIENCE class under my belt. But I am very motivated to learn a new marketable skill. Thanks again.GNUStep Looks like one possible route you might consider exploring. I'm not sure if it would 100% replace XCode; XCode is in many ways to Objective C what Visual Studio is to C#. It's possible to write programs in the LATTER without the former but it's an uphill battle against convenience.

1843.	Solve : batch programming?
Answer» Hi, I have folders named LIKE this 201601,201501,201602,201603 , basically yyyymm as the folder name. considering for today's month the folder will be 201606. I need to delete all the folders which are 6 months older than 201606. Also, I don't want to delete the folders by the modified date but by checking the month and year in the folder name and comparing it with current month's folder year and month and delete if the folder is more than 6 months old. Are the folders all under one top folder? Folders are inside E:\output , Basically like this: E:\output\201512 E:\output\201601 E:\output\201602 ...... ... E:\output\201606 Do you want to manually input the current month or have the script calculate it? I get the current month yyyymm that is 201606 as a user specified input parameter to the batch script.The user types (e.g.) 201606 at a prompt? Yes. Call the script : C:\Xyz.bat 201606 Inside the script Set date= %1 Which sets date as 201606, and I use %date% throughout as a reference to user defined yyyymm input. Better not to use %date%, as that is a reserved system variable (also %time%). Batch/VBscript hybrid There should NOT be ANY other folders except those named YYYYMM This may need changing if your system date format is not dd/mm/yyyy @echo off setlocal enabledelayedexpansion echo wscript.echo datediff("m", wscript.arguments(1),wscript.arguments(0)) > monthdiff.vbs set thismonth=%1 set thismonthdate=01/%thismonth:~4,2%/%thismonth:~0,4% echo This month: %thismonth% echo Using date: %thismonthdate% for /f "delims=" %%A in ('dir /b /ad') do ( set foldername=%%A set folderdate=01/!foldername:~4,2!/!foldername:~0,4! for /f "delims=" %%B in ('cscript //nologo monthdiff.vbs "%thismonthdate%" "!folderdate!"') do set folderage=%%B if !folderage! gtr 6 (set action=delete) else (set action=keep) echo Folder %%A is !folderage! months old, action: !action! if "!action!"=="delete" ( echo deleting !foldername! REM To avoid "Are you sure" prompt: REM use rd /s /q "!foldername!" REM Test script first, and if it works OK remove ECHO ECHO rd /s "!foldername!" ) ) echo Complete pause Hey, Thanks a lot . This works..!!! I have one more question similar to this for the FILES deletion based on dates in the FILE name. Will post in a while. Extension: To delete the files in a specific folder : File name is like this xyz_yyyymmdd.dat.gz Say in a folder E:\ZippedFiles, I have files like these present xyz_20160526.dat.gz xyz_20160627.dat.gz xyz_20160528.dat.gz xyz_20160529.dat.gz xyz_20160630.dat.gz xyz_20160531.dat.gz xyz_20160601.dat.gz xyz_20160602.dat.gz xyz_20160603.dat.gz File xyz_20160529.dat.gz is a Sunday File and xyz_20160531.dat.gz is the last day of the previous month file. Expectations: To move (not copy) the Sunday file and last day of previous month file to E:\Backup Conditions: 1. Batch file should be configurable to pick a day of week for running the script and is dependent on a user fed variable no_of_days. Lets say I am running the script on a Friday, so if I pass a variable no_of_days==5, it will backup sunday file. if on a thursday , then no_of_days becomes 4 basically current_day - no_of_days= Sunday (current day minus no of days should return a sunday) and backup the sunday file. 2. Also, after moving files 20160529 and 20160531. It should not delete any files for the current week but it should delete all the files of the previous week except sunday file if present. Example: files 20160530,20160602,20160603,20160604 are left in the current folder whereas 20160526,20160527,20160528 are deleted. files 20160529(sunday) and 20160531 are moved to back up folder. 3. after running the batch script expected: New location: E:\Backup\xyz_20160529.dat.gz and E:\Backup\xyz_20160531.dat.gz deleted files: E:\ZippedFiles\xyz_20160526.dat.gz, E:\ZippedFiles\xyz_20160627.dat.gz ,E:\ZippedFiles\xyz_20160528.dat.gz Not modified: E:\ZippedFiles\xyz_20160530.dat.gz, E:\ZippedFiles\xyz_20160601.dat.gz, E:\ZippedFiles\xyz_20160602.dat.gz, E:\ZippedFiles\xyz_20160603.dat.gz, So no_of_days is the day number, counting from Monday=1? A quick question: is this stuff for your job? Yes . I do have this one figured out to a certain extent but the script doesn't look very neat since I have just started with batch and Vb scripting. Answering the other question: No of days is passed to calculate the Sunday date. C:\xyz.bat today's_date no_of_days (2 parameters) if today's date is 20160603 then no_of_days =5 so that 20160603 - 5 (days)== 20160529 (sunday) if today's date is 20160602 then no_of_days =4 so that 20160602 - 4 (days)== 20160529 (sunday) A script can know today's date, today's day number (1 to 7), and the date of last Sunday without any user input.

1847.	Solve : Create a bridge between phone calls and a program?
Answer» Hello, I would like to know if what I am about to tell you is possible. I will try to make it simple and please apology, my English isn't very good. The idea is to create a bridge between my ip phone system (A) connected to my computer and a program (B) that contains all of my customers profile pages. To be more specific, when I receive a CALL (A), it sends a signal to (B) and it OPENS the profile page of the customer who's calling. 1- I am able to automatically import daily the folder that contains all the .txt files (incoming call history) (A) and refresh every second the .txt files in an Excel file (1). 2- I am also able to automatically import daily all of my customers (and new customers) profile from SQL 2014 to another sheet in Excel (2). When I receive a call (A), the phone number is written in Excel (1) and sends a ''signal'' to Excel (2) to ''MATCH'' the phone number with the customer number. Here's the part where I need help. 3- When there is a ''match'' between the phone number (calling) and the customer number in my Excel (2), I would like to send a ''signal'' to open my program (B) and write the customer number in the search bar so that it opens automatically the profile page of my custommers. I have been searching for an interprocess communication solution to send data (customer number) from my Excel (2) to my program (B), but didn't find any clear solution. (I can also use Access instead of Excel) Is it possible ? Thank you very much Its PRETTY involved, but you could tap into Caller ID and use that as a means to identify who it is thats calling for repeat customers. Which VOIP system are you using? Some come with features that allow for you to avoid reinventing the wheel. I made a system a while back that integrated with ShoreTel VOIP system for example with software that monitored the corporate network for 7 locations and it would call me on my cell phone and play WAV files telling me where the problem was for example, this way I was able to deal with a problem as it happened vs having to wait for people to complain that something isnt working. There were a few things I was not able to easily integrate which required some electronics and a audio bridge where I had a set of PC speakers in a cardboard box with a shoretel handset in the box with it and I added a relay to control when the handset was off the base of the phone to simulate the phone on and off the hook. I ended up using a USB Relay control with a program written in C++ to turn on and off the relay for the handset on and off the hook. So I wasnt able to do it all through just a software integration. Yours though at least you wouldnt need any hardware modding like I did, however depending on the VOIP system, the ability to capture that Caller ID info is key. First of all, are you a programmer looking for advice from other programmers or new to PROGRAMMING and need someone else to do the majority of the work? Trying to assess what level of help you will require and what programming language you plan to use to integrate this? If the VOIP system was one that has open source software that integrates with it, that would be the easiest for modifying and tapping into the Caller ID info. Once you have the Caller ID info you can then run that across a database and have that display all the info you need. I wouldnt bother with Excel and would keep it all within the database and the GUI that you use with the database such as a web based interface. To me looking at this, you would want to write a service that monitors the Caller ID info, and when the service detects a change in the Caller ID when it checks it on say a 2 second interval it runs that number against the database, and then if there is a match it displays the info you need. Thank you very much for your answer ! I really appreciate. I use ShoreTel VOIP system with the ShoreTel communicator (14.2) . I am actually studying to be an IT Engineer, so I am not the greatest programmer, but I am working real hard ! I am still thinking on which language to use. But I think I will go with Importing the data from my SQL database to Microsoft Access. So when I receive a call, I can see in Access (Interface that I created) the entire profile of my customers before I answer a call.

1848.	Solve : NBSTAT in Windows 10?
Answer» Hi All, I have WIN 10 enterprise 64 BIT. I am also an ADMIN on the machine. I opened a command prompt as an admin and tried to run NBSTAT The machine SAYS no such command or something like that. Has win 10 got rid of this command? I have an IP and need to know the machine name. I was using NBSTAT to get the name. Any ideas? Thanks I believe you want to run NBTSTATQuote Nbtstat is a diagnostic tool for NetBIOS over TCP/IP. It is included in several versions of Microsoft Windows. Its primary design is to help troubleshoot NetBIOS name resolution problems. https://en.wikipedia.org/wiki/Nbtstat Ok...it was a typo! My bad. Got my script to work once I put in the right stuff. Thanks! Glad you got it sorted out.Just my two cents. If you put nbstat into a Google search, Google will then say, "Showing results for nbtstat". Amazing how Google reads our minds.

Answer» Just sharing a program I was messing with to generate all combinations of A thru Z for 26 character length only. With winter storm here and an IDEA on my mind to toy with, I decided to build upon someone elses project out of curiosity as to how quickly a modern computer could process to generate all combinations of A thru Z with all letters A thru Z involved without repeat letters as for you can only have 1 of each letter type in the shuffle. I expected it to process 26 to the power of 26 quicker for all combinations of same case A to Z, but then I realized that its single-threaded execution and so only 1/4th of my Athlon II x4 2612Mhz quadcore was being used. So I do come here with a question though which is..... is it the IDE that compiled the source code that basically governs whether its a single-threaded execution or is it in your source code that you need to add to specify to tap into the use of all cores to get full 100% CPU utilization? As for with the current code to get 100% utilization the trick would be to create 4 programs with 4 blocks of the alphabet range to work WITHIN and then set core affinity so that each program when executed runs on its own core.
