Hi Experts,

When we want to lock the computer we do the following:
Ctrl Alt Del
(A dialog box appears)
Lock computer

When we want to unlock the computer we do the following:
Ctrl Alt Del
(A dialog box appears)
Key in password
Enter

Using VB script in XP Professional is it possible to:
1.      automate the above,
2.      automate a shutdown at specified time?

Thanks.
1) I would not recommending scripting the entry of user passwords, this will create large security holes. PERHAPS if you could explain a bit more of the purpose there might be a better work around.

2) To shutdown XP I would simply use the built in Shutdown.exe program.

Type shutdown -? to get a LIST of options.

You should be able to force the shutdown of a locked MACHINE if the running scripts has the correct privledges (IE: admin)

The intend is to start up the pc to run some programs,
upon completion force shutdoown the pc.

Thanks.
How do you intend to start the system in the first place?Thinking of using the BIOS to setup the Pc on certain days/time.

Thanks.Does your BIOS cater for this?You can setup Windows to automatically login on startup that would take care of the login without the need for CTRL-ALT-DELETE, so long as you are okay with this.

I imagine the shutdown command should work regardless of whether or not the workstation is locked.

As for the auto-startup, if BIOS doesn't support it you could hard wire it in such a way such that by plugging   in the PC turns it on, and then hook the plug up to a timer.

I had a machine setup like this before, but it was pretty hard on the power supply, it was easier to just leave it on all the time.

I'm fairly NEW to batch scripting, and
I've seen Batch File logon scripts that run IMMEDIATELY after a user logs on to his/her ACCOUNT. I know these scripts can be used to connect to network drives and such like below...

Code: [Select]net use R: \\officeserver\shared
net use P: \\officeserver\appsand my question is how do they get this file to run immediately after logon?  For a single workstation, try putting the login script in the "c:\documents and setttings\all users\start menu\programs\startup" folder. The script will run no matter who signs on.

On a domain network, the script runs from the server. The network administrator needs to set this up.

Hope this helps. 8-)   Thanks, this was exactly what I was LOOKING for.

When I try to compile, I GET this screen. No matter what I try, the "Run" BUTTON STAYS grayed out. HEEELP! I am TIRED of BlueJ!

im making an AUDIO converter (mp3, wav, wmv.. all to all) using vc++. any suggestions for a good algorithm and where i COULD FIND it??
any other suggestions are also welcome.. tips and guidelines as to how i should go about it..[highlight]SourceForge[/highlight] WOULD be a good place to start.

Hi

I NEED to FIND the LIST of all the servers and the database names in SQL Server but using C#.net.

I am writing an APPLICATION using C#.Net. I need to find all the servers and DB's so that I could add them to a list box to be selected.

The names of servers and databases should be in Enterprise Manager. But I need a piece of code in C# to list all of them. I will than TAKE them and add them to a combo box in the interface.

Please Help

Hi there people!
I'm TRYING to write a function in C language that reads from the user a set of integers separated by ',' (commas), but I'm having difficulty isolating the integers from the characters. I'm not sure if I should do it using a "for" or "while" loop,...
So if the input is something like: {100,20,50}
then, I should be ABLE to store the integers 100 20 50

Anybody got any idea how to do that??
I would really appreciate the help!!
Thanks.Check out the split function which RETURNS a zero-based, one-dimensional array containing a specified number of substrings.

Good luck.  8-)

Hi

I need to add code in C#.Net that allows a USER to RIGHT click and select the COPY FUNCTION. This would allow the user to copy information to the clipboard and paste elsewhere.

SOS
HELPFor text, use the SetText method:

Clipboard.SetText(data, dataformat)

To retrieve the clipboard data, use the GetText method:

Clipboard.GetText(dataformat)

Note: there are other formats besides text (images, audio, etc). Match the method (Get/SetImage, Get/SetAudioStream, etc) to your data format.

Hope this helps.  8-)

Note: The C#.NET help index has much information on this and many other subjects.
This does not really help

I need a fuction that I can use from any where on the form.
That applies to a single object such as a textbox or image, etc.

I need something more generic. The same piece of code should work on any object not just a particular object.

Is this possible???
HelpI would think you could QUERY the dataformat of the object and handle it with the appropriate code. Not familiar with C# but in VB this would be the way to go. Pass the object and the dataformat to the function and set up the set/get commands as needed.

Good luck.  8-)

For creating a log file i have to combine text and the result of the copy command in 1 text line in a new file.

now:
echo %varname% >> LOGFILE
copy x Y >> logfile

this result in two lines in the logfile
varname
1 files copied


is it possible to connect it to get the following result:

varname ; 1 files copied

1 line in the logfileMost versions of DOS do not have an echo command that will supress newline. This means that any echo command will automatically move to the next line.

You can create your own version of echo that supresses newline with the following command

ECHO ,8P_,FPZ0U]0U[,B0EWP_[[email protected][email protected]O!A>%TEMP%.\echoit.com

This creates a quick assembly file called echoit.com in your %temp% directory.

Then change your commands that USE echo command to use echoit instead. So something like

ECHO OFF
ECHO ,8P_,FPZ0U]0U[,B0EWP_[[email protected][email protected]O!A>%temp%.\echoit.com
%temp%\echoit %varname% ;>> logfile
copy x Y >> logfile
del %temp%.\echoit.com ;DELETE the program when we are done with it.

You don't have to create and delete the file each time. You could just make it once but then your batch would be specific to the one machine that has echoit.com on it.
Thanks, it works fine

Hi,

I need a program that activates the key "q" releases it and then activates key "e".
I also need a start key "k" and "k" to stop it again.

How do i make that program?
I don't now anything about PROGRAMMING, but I hope that someone can help me.

Sorry for my bad english.

Regards,
ColzenYou MEAN like a PLAYER PIANO?  

You can probably mimic this LOGICALLY (physically you're on your own).  Which language were you planning to use?

Need more info.

 :-?
Rather than re-invent the wheel, why not download the source code for >AutoHotKey< which does this plus much more?Didn't know that program, but it did it  
I do have a little trouble though. It's not easy to stop it again, the timing must be allmost perfect  :-/

Hi experts,

Files with different datas are kept in a common subdirectory.

Would like to KNOW how many times a particular file have been open
and by dates. This information need to be saved in a log (text) file in another separate (not common) directory.

(The intention is to know which files is the most POPULAR. Using XP)
 
As a newbie, which scripting language is the best and which web site provides samples?

Thanks.

It's easy enough to WRITE a script that will monitor events resulting in a change to the file system. Opening a file for input (reading) does NOT produce an event that can be monitored. With a little imagination, you could log the events to a file and create a script to summarize the activity. (EXCEL?, perhaps)

This script will monitor file system events in the c:\windows\system32 directory:
Code: [Select]strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

Set colMonitoredEvents = objWMIService.ExecNotificationQuery _
    ("SELECT * FROM __InstanceOperationEvent WITHIN 3 WHERE " _
        & "Targetinstance ISA 'CIM_Datafile' and " _
            & "TargetInstance.Drive = 'c:' And "_
             & "TargetInstance.Path= '\\windows\system32\\'")
Do
    Set objLatestEvent = colMonitoredEvents.NextEvent()
         'WScript.Echo objLatestEvent.Path_.Class & " " & objLatestEvent.TargetInstance.Name

    Select Case objLatestEvent.Path_.Class
      Case "__InstanceCreationEvent"
             WScript.Echo "File Created: " & objLatestEvent.TargetInstance.Name
      Case "__InstanceDeletionEvent"
             WScript.Echo "File Deleted: " & objLatestEvent.TargetInstance.Name
      Case "__InstanceModificationEvent"
            WScript.Echo "File Modified: " & objLatestEvent.TargetInstance.Name
    End Select
Loop

There are many free scripting languages. Choosing one is like wine. Choose the one you like. VBScript and JScript are installed free with every Windows version except Win95 (A & B).  They're easy to use and understand.

Perl, Python and PHP are popular but are geared to the internet. Can be run within Windows.

REXX comes from IBM mainframes (VM/CMS). Both versions (Classic & Object)  have been ported to Windows. (note: the REXX IDE is proprietary ($$$) but the interpreter is free).

The nice thing about script is they are not compiled and linked. Running under an interpreter, all you need is an editor (notepad works fine) to create a text file.

A good script site with plenty of VBScript examples is the Script Center

Good luck.  8-)

Hello,
I've started learning basic batch FILES, and was wondering how to open docuements (I.e 'My Documents') once the Batch FILE is opened...
Thank you
,SpedzDo you mean a batch file to open the My Documents folder? If so, all you need in the batch file is

Code: [Select]CD C:/Documents and Settings/[YOURNAME]/My Documents
assuming you are running Windows XP. I don't know the layout of the other OPERATING systems that well.

Please let me know if that's not what you want. I'll be HAPPY to help.  8-)Is  this code supposed to open a window on your desktop? For me, I get an error when I try to run that code. I put Quotes around it and I could get it to cd to the directory. Please explain how to open the window up. I am using notepad to MAKE the batch file.I am using XP Professional. Thanks for your help

You need to start the explorer.
Try this sentence:

explorer "C:/Documents and Settings/[YOURNAME]/My Documents"

ok so i've written an APP and i've created an icon for it, how MIGHT i GO about inserting the icon into the program?Many languages have a forms property SHEET where you can point to an icon during development. You can also RIGHT click the current icon for the program, choose properties, click change icon and point to the icon you wish to use.

Happy Computing.  8-)

Hello,
I've the PROBLEM that when i run any graphics BASED program of C++ ,a blank screen appears, no result display.The file compiles successfully but no output GENERATED while other (Non graphics programs) are successfully compiled and output is generating.I've SVGA Card and EGAVGA files also in bgi directory but no graphics are displayed,although the correct path is mentioned in the file.
Thanks for your valueable timeXP Doesn't like to support DOS at all.

Try DOSBOX http://dosbox.sourceforge.net/news.php?show_news=1

It's free and MIGHT help.

But Whoever told you to build long, long nested IF ELSE structure in BATCH needs to switchover to teaching something else, maybe basket weaving

Or was that your idea?

My point is the long, long, nested, nested IF ELSE is hard to read.

I am writing an html code using radio buttons. The program is a unit conversion program, where first you select a radio button to convert either length, weight, or volume. after the user selects length, weight or volume, it should then display another set of radio buttons for the user to select the conversion direction. for example, if the user selected to convert length, the second set of radio button options should be pounds to kilograms, or kilograms to pounds. After this occurs, the user then enters in the number they would like to convert and then hit the convert button to perform the conversion. For me, I am having difficulties displaying the second set of radio buttons. I am thinking of using the onClick property, and then call a function, but I can't seem to be able to do that. any suggestions?jQuery.

Use named divs:

Code: [Select]<div id="div1">Extra form controls here</div>

Then use onClick events to show or hide elements as required.

Code: [Select]$("#div1").hide();
i haven't LEARNED about JQuery. I have created the set up and layout of the program. But problems right now, lie in the calculate function and the result text box. I'm not sure if i'm writing my calculate function properly. and also, when the user clicks the calculate button, the result is displayed in the results text box below the calculate button. here is my code

Hi all,please can anyone help me,i have almost finished building my web site,(i have bought my domain name already)the problem i seem to have is that ,my web site,is placed in my/document/index.html,what i want to know is when i pay for a host and upload my web page,do i change my main index page to http://or do i leave my main index page just as it is,thanks,GillyJust leave the name index as it is because you have to it for you homepage but every thing els you can rename itthanks Chia,when you say i can rename all the other files is this really nessesary?gillyI'm not sure if this is what he means, but:

you must leave the first page that you want an internet user to see as "index.htm" (or whatever extension you have it as)
All other files that link to "index.htm" have to be recoded so that they do not go to "C:\My Documents\index.htm" but to "../index.htm".  You might know this already, but "../" means go up a level, so depending on how deep your files are stored on the domain servers, a link to your "index.htm" may look like "../../../../index.htm".

Also, I think "./index.htm" might send the browser to the topmost file, but I'm not sure, so don't trust me on it. (note, only one period)

-hope it helps
-rockNo, ./index.htm sends you to the index.htm file in the current folder.

In your links, follow this principal: '/' means the top level of your web folder.  '/index.htm' then means your home page.  In the html files, you can just call it '/index.htm' - you do not NEED to specificy the full 'http://whatever.domain.com/index.htm' - the http and domain PART are implied.

Hope this helps.I dont know as much as you robpomeroy but on most of my Sever said that the homepage must be called index but why? Cant the Internet take a different nameIt's because of defaults set on the web server.  If you just type the domain of a website, with no page (e.g. http://www.mysite.com), the web server has to decide which web page to send to the browser.  (There is no web page called ""!).  The web server typically looks through a LIST, displaying the first page it finds, eg:

index.php
index.asp
index.html
index.htm
DEFAULT.html
default.htm

If your home page does not have one of the default names, the server will not know which page to show and will instead produce a "Page not found" error.  So this is why you should choose one of the default names for your home page at least.

It's not a big problem.  The home page has got to be called something, right?Nice explaining rob  
I know it no big deal  
ThankYou can always access your server SETTINGS and tell it to look up whatever name you want  
I think it might also look for home.[whatever], maybe.Not all ISPs will allow this.  "home.htm" only works if the server has been configured that way.  In my experience, that's quite rare.  "index.html" is the standard.  "index.htm" is Microsoft's stubborn refusal to depart from the highly limiting 3 character filename extension.  "default.html" is non-standard.  "index.php" is standard, but only on servers supporting PHP.

i am looking for a c++ function that will start ANOTHER program  EVERY ONE that i have found so FAR just gives me a lot of errorsYou dont need help on this  
Google is your help  
Well this is not a Computer problem at all  perhaps a google search for "c++ start external program" might help?

I'm trying to erase the content of a specific folder with a batch file, not the folder, but just everything inside it. I am using:

DEL  c:\TEMP\*.* /s/f/q

and it works great, the only problem is that it only ERASES files not sub folders. How can I get it to erase EVERYTHING inside my "c:\Temp" folder?

Thanks

cd /d c:\temp &AMP; del /q *.* & for /f "DELIMS=" %%A in ('dir /b /ad') do rd /s /q "%%~dpnA"

thanks a lot Salmon Trout, it's work perfectly

here I  am righting a perl script something like FOLLOWING :

Code: [Select]#!/usr/bin/env perl

#define some var...

sub function_main{

if (var eq some value){
  Code_piece
} else {
  Code_piece
}
}
now here inside if and else some piece of code is calling in different conditions so I try to remove duplicate code here like :

Code: [Select]
#!/usr/bin/env perl

#define some var...

sub function_main{

   sub function_child{
       Code_piece
    }

   if (var eq some value){
      call function_child()
   } else {
      call function_child()
   }
}



So its giving me syntax error at the last line.

Here is the question : Can we define the Subroutine inside any existing subroutine?
If yes How? what mistake I did here?
If no  then whats the other way ? because I dont want that piece of code outside of the function_main, as I am using some local variable of function_main in that code and if I create a subroutine(function_child) outside I need to pass some 20+ values while calling that subroutine function_child,.

THANKS



the two parts are the if are the same.

Code: [Select]
if (var eq some value){
  Code_piece
} else {
  Code_piece
}
is equivalent to this:
Code: [Select]Code_piece


If there actually is different logic, REFACTOR it so that the duplicated code only get's called once.

Inside the if the code is calling for the loop .

I have an Array in which i have combination of array and normal var,
so if the array element slected is an array that will go in the if condition and run that code for each element of array.
and if the array element is normal var then I need to run that code once only.

Example:

Code: [Select]if (array{i} eq array)
{
    foreach $var (array{i}){
       code()
    }
} else {
    code()
}
 

If i dont use if and else condition how can I separate it?refactor it. That looks like it could be turned into a recursive routine.

Another method is to turn single elements into a single-element array and follow the iterative logic.



Thanks for the help .

Its working Now I missed one } at the end that why the error is comming I can WRITE the subroutine inside any other subroutine.A nested routine will access VARIABLES from their parent scope, but the nested routine will remain bound to the same variable from the first call. That is, when you call the parent subroutine again, the inner routine is still closed over the local variables from the first call, which are now orphaned. Example:

Code: [Select]#!/usr/bin/perl
use strict;
use warnings;

for (1..3)
{
  print "run: [time $_]\n";
  run();
}
 
sub run{
  my $counter = 0;
  inc();
  inc();
 
  sub inc{
    $counter++;
    print "Counter = $counter \n";
  }
 
}

output:
Code: [Select]run: [time 1]
Counter = 1
Counter = 2
run: [time 2]
Counter = 3
Counter = 4
run: [time 3]
Counter = 5
Counter = 6
As you can see, even though run explicitly sets counter to zero, every call to inc still increments by one. This is because the inc() routine binds to the $counter variable from the first call. If the routine in which you are adding nested functions is called more than once, it won't work as expected since all the nested functions will be closed over the first call, not the current one.

Hey guys, Just wondering if any of you guys are familiar with HTML5's WEB Socket IMPLEMENTATION? I intend to create a system or an application relating to Web Sockets but I'm just not sure what exactly. Any ideas would be much appreciated. Thanks in advanced everybody.  I'm still doing some research on this for my final year project but it would be great coming from someone who actually implemented this before in their projects or etc. HTML5 web sockets are an unstable specification not worth programming against yet, unless you want to have to constantly revisit it as the spec changes and as browser support changes. At this point the only major browser that supports it is Chrome, so calling it a "web standard" at this point is pretty laughable. By the time the other browsers decide to support it (Opera and FF did, but they dropped it because the spec was flip-flopping all over the place and still under scrutiny) it will be completely DIFFERENT than what it is TODAY anyway.

Banking on the current web sockets implementation for a project, application, or product is premature unless you have control over the browser that is being used by those who will consume the service, such as via an intranet.

I see. So besides that, What other projects you would suggest using HTML5 from your PERSPECTIVE?

I need to subtract 2 newly created columns from each other. Each customer has one or more orders and each order may (or may not) have a discount. So i have used the SUM and GROUP function to total the order prices and discounts. This has created 2 NEW columns called 'TOTAL' and 'DEDUCTION'.

What i would like to do is subtract the 'DEDUCTION' from the 'TOTAL' to find the revenue generated, but i'm struggling to find a solution. Below is the sql that i have created so far, in case it helps.

Quote

SELECT ghh.member_id, SUM (ghl.days*gr.daily_rate) AS total, SUM (ghl.discount) AS deduction, pr.firstname, pr.surname, mem.registration_date, pr.person_id

FROM garment_hire_header ghh, garment_hire_line ghl, garment_at_location gal, garment gr, membership mem, person pr

WHERE ghh.hire_id=ghl.hire_id
AND ghl.garment_at_branch_id=gal.garment_at_branch_id
AND gal.garment_id=gr.garment_id
AND ghh.member_id=mem.member_id
AND mem.person_id=pr.person_id

GROUP BY ghh.member_id, pr.firstname, pr.surname,mem.registration_date, pr.person_id
ORDER BY total DESC;

Are you sure those SUM functions are working the way you expect?

I've got all the data in spreadsheets so that i can do some filtering and addition to check against the SQL queries.

I am a beginning programmer and am attempting to create an invisible entry when using standard input as the input to set a variable.  

I need the question to display on screen and possibly the # sign to appear instead of the characters typed for the input.  

If you have a line of code for this, please reply with it or with suggestions.

Thank youPosted in The wrong place.

R0SSTyped data is not taken from the command line and made available from the keyboard device until the enter key is PRESSED. Since you cannot read a single character as it is typed, there is no way to intercept the character and echo a # to the command line. Instead, you can only read complete lines.

You would need to write a front-end GUI for this.

Hope this helps. 8-)As was mentioned, there is no "built-in" batch file way to do this.

However, if you know a little .NET you can check/modify the article here

Right now, I'm very lost as to what to do. I'm still a novice at C++, C, Java programming(I only know these few).

There's a lot of programming language out there, VISUAL Basic, asp.net, Perl, etc. I don't know know where to start(again)? It's quite confusing for me as there's so many to choose from. I also heard of Linux programming, I wanted to learn that, but that is also a whole lot of process for me. I saw books on Linux kernel, nutshell. It will direct me toother further topics.

Anyone can advise me which programming language is better to start off(nevermind about what I am learning now)?

Thank You.While I haven't even started to think about learning C++, Perl, or any of those (mainly because they look so hard ;-), I started out with HTML/CSS, and then moved up to Visual Basic coding.  I'm now trying to learn batching in Windows (which probably isn't MUCH higher than HTML/CSS on the hardness level).  I'm thinking Javascript or PHP is next on my list, maybe at the same time.

So, what I'm trying to say is, Visual Basic is probably a good starting point.  I took a really simple class my Sophomore year of Highschool and it got me jumpstarted.  It is a simple example of proper syntax and structure.  From there, you can branch out to the more complex LANGUAGES.

-rockComputer Programming Rules  
There are lots of choices of programming language.  As to which to learn?  Well that would depend on what you want to do.  If you want to do a few simple things with web pages, beyond what HTML can do, then javascript is an obvious choice.  It's also a fairly forgiving language in some ways.

I would definitely start with an interpreted language, because you can error-check it much more quickly and easily than with COMPILED languages.  Again, if your FUTURE needs are likely to be web-related, then perl or php would be excellent choices.

On the other hand, if you want to get into kernel programming then you are faced with a couple of stark options: C, or even worse, assembly language.  Neither is especially easy to learn.  But if you master either of those, you will start to have a fairly good idea of the way computers tick.

Go for a mainstream language anyway, to start with.  That way you'll find lots of support resources and tutorials.  I would suggest one from this list (but this is not exhaustive):

For web design:
perl
php
python

For GUI programs:
Visual Basic
Visual C++
C#
Delphi

For non-GUI programs (console-based, device drivers, etc):
C
Pascal
Modula-II (or whatever version we're in now)

For highly logic-driven and abstract programs:
Lisp
Prolog

For extreme pain:
Assembly language
Machine code

Some programmers will note the glaring absence of Java in this list.  That is because pretty much without exception, I have found Java programs (beyond simple web gadgets) to be sluggish, crash-prone and idiosyncratic.

um.. how does the % THING work and how do I use it?
Here it is...yeah, but that doesn't EXPLAIN it well enough, I've already read it. OK - then TRY here.  Lesson 12 looks LIKELY...

Hey, I need some lines to make a btach file COPY and paste itself where I want it to.  Can someone TELL me how??  Copy/Paste is a Windows function. Can you not simply use the batch copy command to put the file where you want it to go?

type copy /? at a command prompt for full DETAILS.

 8-)what do you MEAN, at a command prompt, as you can SEE by my status, im a newbie.  Click START-->Run. When box appears type command (Win95, 98, ME) or cmd (WinNT, 2000, XP), then click OK or hit enter. The black window that appears is the command prompt.

Newbie status refers to how many posts you've made. It has nothing to do with your knowledge of PC's.

I would like to create a batch file that will:
1.  Open a .TXT file
2.  read the first LINE of the file and save that first line into a directory with a new file name.
3.  read the next line of data and save to a new file.
4.  The script should be able to sequentially name the new file (ie.  newfile1.txt, newfile2.txt...newfileN.txt)
     as it moves to a new line.

The source file may have over 10,000 lines.

I have been able to accomplish this with a macro in Excel but I think it would run faster in DOS.
Since I don't know DOS a little help with this will GET me started.Without an OS, any solution is only guesswork. Why would anyone would clutter their HARDDISK with over 10,000 files?

Code: [Select]echo off
set count=0
for /f "tokens=1* delims=" %%i in (textfile.txt) do (
      call :Output %%i
      )
echo %count%
goto :EOF

:Output
      set /a count=%count%+1
      echo %1 > newfile%count%.txt

If there are any DOS special CHARACTERS in the lines from the file, you may get unexpected results.

Hi all,

Can u plz help me by showing some way to run MS office program like Access thru cmd command.

regardsWhat are you trying to accomplish with this?I am trying to autmoate a process of importing TXT files to multiple MS Access files. Thinking to have batch FILE that run each MS Access file separately and then thru Access I can import the txt files...so main objective is to open MS Access file thru the DOS batch file...
The executable for Access is msaccess.exe, so yes you can run it from a batch file (you'll need a PATH of course).

There are not a lot of command line switches for Access. What are you planning to do once Access opens?

Just for reference
http://support.microsoft.com/default.aspx?scid=kb;en-us;209207once Access open, I want to import txt files into predefined tables...
I am trying to make this process automated since I got too many txt files to be imported to multi Access mdbsorry...can I reformelate my question to be like this...I need the batch file to open specific Access programms then after that the thru Access I can import the txt files

ThanksFrom the reference posted by Ghostdog74, you can use the /x SWITCH to run a MACRO when Access is executed. You cannot pass instructions from the DOS command line to Access.

An alternative way would be to write a script to create a Access object. The script would be able to pass instructions to the Access object.

Good luck. Thanks and Merry Christmas

I downloaded the free Borland compiler for C++ and added BCC32.CFG and LINK32.CFG to the BIN folder but am not able to get it to work.

At first the error message was that it could not find the (source) file even when I changed to directories right to the folder that held it.

After numerous trials and errors it finally recognized the file containing the code. However there was a steady stream on code errors. This was not code I wrote but was very short from a tutorial on C++.

E2209 Unable to open include file isostream
E2282 Name space name expected
E2451 Unidentified symbol cout in function main ()

I tried running an example program from Borland and came up with 19 error messages.

More trial and error and now it cannot find/run BCC32 the compiler execute command.

I am running Windows XP on an HP laptop and use the command line prompt. Prior to downloading the compiler I had to reformat the hard drive (from the recovery disk that came with the computer).

DOS - I have very few dos commands available- find, tree, edit and other lead to error messages that these are not recognized commands.

Any help, suggestions, or references would be greatly appreciated.

THANKSAfter you formatted the drive did you reload XP? The commands you mentioned are all external to the OS which leaves me to believe you simply have a basic DOS system or a very incomplete XP system.

What lead up to you having to format the disk?

Let us know. Yes. I reinstalled XP and the drivers with the restore disks that came with the computer. The only thing I did not put back were the original applications because I have my own software that I reinstalled.

I had a bad virus that I eventually GOT rid of but I think remnants were still hiding on my computer. XP was not functioning correctly. For instance right clicking the mouse did not bring up a menu in windows although it did in some applications; internet explorer did not have an address bar and I could not get my toolbars back. Since reformatting, XP and IE are working correctly.

How can I get a more complete set of dos commands? Do you think it would be on the applications disk that came with the computer?

Why do you think the Borland compiler is not now working and at one point didn't recognize basic C++ coding?

Thanks for taking the time to respond.Check your path: set path from a command path. Both c:\windows and c:\windows\system32 should be on the path. If there are other directories on the path, don't worry about it.

Also, navigate to c:\windows\system32 from a command prompt. Use dir and check to see if find.exe, tree.com and edit.exe exist. Did you have any problems with the XP reinstall?

As for Borland, this link may help: http://www.stu.qmul.ac.uk/primer/borlandC.html

Hope this helps. The C:\>set path  results in a "Syntax error".
setpath = a "not recognized as an internal ...." error.
path results in "Path=";C:\BORLALND\BCC55\BIN"

I can find tree.com and find.exe but not edit.exe. There is however an edit.com, edit.hlp and an edlin.exe.

The link you referenced does not look like what I have. I downloaded the free compiler and that is all that is in there.

Should the DOS that comes with XP have all or most of the commands listed on sites that show DOS for Windows XP?


ThanksIt appears the C++ install mucked up your path, which would explain why you can't find edit, tree, find, and PROBABLY all the rest of the external commands. They're installed, Windows just can't find them.

Program installations usually insert or append to an existing path; not build one from scratch. According to Borland this is what should have happened (read the entire article). Did you encounter any problems during the install?

When you checked the path, was it from the MS-DOS prompt (command.com) or the Command prompt (cmd.exe)? There are separate paths for each one. The easiest way out is to do a system restore back to a date/time before C++ was installed. Since you've already done it once, you may want to re-load XP again.

In the future, create a restore point prior to program installations.

Good luck.

Note: NT, Win2000 and XP do not come with DOS; just an emulated version thereof.PROGRESS (I think)!

As long as I:

change the command prompt to C:\Windows\System32>
use the command Path=%Path%;C:\Borland\Bcc55\Bin
save the source code to the system32 folder

the computer will run Bcc32 and is able to find the source file.

That's the good news. The bad news is I still get an error message.

Turbo Incremental Link 5.0 for Win32 copyright 1993, 2000 Borland
Fatal: Illegal option: Lc:\Borland\Bcc55\Lib

A search found this expression but so far not how to cure an error message. Any suggestions how to get over this (hopefully last) hurtle?

Thanks
I probably found the same info as you, but I suspect the problem in the the .cfg file. You might want to checkout: C++

From what I have read, this is more than one persons nightmare.

Hi,

Can anybody tell me how to control the main form. I want to make the main form appear depending on a check that i am GOING to make. For example when running the exe, i need to check first if the username and password is already present in the Registry. If it is present then i wont show the LOGIN. If the login is not correct, i shouldn't get the main form but the login again.In which event of the main form should i do this check so as to make the main form appear depending on the result of this check?
Not up on C++, but most object languages use the show method to produce a form.

Have you program start with the login form, do your check and then DECIDE WHETHER to show the login form again or the mainform.

You could try something like formname.show

Good luck.  8-)I can't start with the login prompt since if the username and password exists in the registry, the login prompt should not appear at all!!

RowinWhen you do the MODULE build (make) you should have options as to which component get control during the module load.  Point the start point to a module that does the check and show whichever form is appropriate.

Good luck.  8-)Ok thanks for the help

The following vb script delete a folder:
SET fso = CreateObject("Scripting.FileSystemObject")
fso.DeleteFolder "C:\myfolder",false
Set fso = Nothing

If I have subfolders by date like:
C:\myfolder\Oct 12
C:\myfolder\Oct 15
C:\myfolder\Nov 30
C:\myfolder\DEC 21
how do I keep the latest 2 subfolders and delete the rest?

Thanks for the input.






Naming your folders with literal months makes things difficult. Consider that FEB, Apr, Aug, and Dec will all sort before Jan. Presumably not what you want.

With script of course you have other options.

Code: [Select]Dim arrdsn()
Dim arrdate()
Const fld = "c:\My Folder"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.GetFolder(fld)
Set fc = f.Subfolders

For Each fs in fc
      ReDim Preserve arrdsn(i)
      ReDim Preserve arrdate(i)
      arrdsn(i) = fs.name
      arrdate(i) = fs.DateCreated
      i = i + 1
Next

For i = UBound(arrDate) - 1 To 0 Step -1
       For j = 0 to i
        If arrDate(j) < arrDate(j+1) then
           tmpDate = arrDate(j+1)
           tmpDsn = arrDsn(j+1)
           arrDate(j+1) = arrDate(j)
           arrDsn(j+1) = arrDsn(j)
           arrDate(j) = tmpDate
           arrDsn(j) = tmpDsn
         End if
       Next
Next

For i = 2 to UBound(arrdsn)
      fso.DeleteFolder fld & "\" & arrdsn(i), True
Next

You may want to substitute a WScript.Echo in place of the fso.DeleteFolder statement to get an idea of what will be deleted before going live with this.

Good LUCK. 8-)

Hi. I am extremely new to BATCH making. Infact I havn't made one thing yet. Anyway I was wondering if it is possible to make a batch file that will SHUT Down my computer at 12:00 at night.

Since I do not know how to do this, can someone make this for me. I WOULD expect it do be pretty simple if it is possible.

Also, how would I get this to work. All I really know is that a batch file is a text DOCUMENT. What wouldI have to do after I get it for it work.

Only one is required. Look for responses in the other thread. More than 1 just makes it confusing.  Thanks.

I hope I am posting this in the right place. What I have is three 3.5 discs that I want to burn to cd. All three disk are for my printer. When I LOAD the cd I want to use an AUTO load script to load all three discs but the problem is, is that when you load them seperatly it then asks for the next one when the first one is finished.
Is this even possible to do or do you think this would be better as a dos question.
Please let me know.Unfortunately almost always this is not possible because the code for the drivers/program is pointing specifically to the A: drive. You may want to see if your printer manufacturer simply offers the same drivers/software on the disks as a downloadable FORMAT, often it will only be one file that can be used from your hard disk drive or CD. Otherwise this will not be possible.Okay....that makes sence to me. THANKS for the info very INFORMATIVE.

When using a datamodule and a database (Tdatabase), how can I retrieve the password that I set in the login prompt? I can RETRIVE the username by:

But for the password it's not working.All I can really say is that you need to figure the password. I am not all that great with C++, as I am jsut starting it.how to figure the password?I can't really say how, because I don't know, but did you make the password?ACTUALLY I will type in the password in a login prompt.
But i need to retrieve it so as to save it in the registry afterwards.
But unfortunately i can't retrieve that password TRY the retrieve command in the prompt. If not, then you just may have to enter it each TIME, then you should write it down.Try the retrieve command in the prompt. If not, then you just may have to enter it each time, then you should write it down.

Hi all.
How can I execute following SQL in bath file
"SELECT Username from LoginTbl WHERE Username LIKE '%.abc'"
The problem is  LIKE '%.abc', batch file understand % like parammeter!

Please help me.
Thank you.
I wasn't aware you could run SQL from a batch file since SQL runs in the context of a database. Oh well, for SYNTAX this may be your answer:

Code: [Select]
"SELECT Username from LoginTbl WHERE Username LIKE '^%.abc'"


I'm curious though, where is the connection to the physical file (database)? And where is the recordset DEFINED for the selected records?

You may want to check out: Reading  Records From A Database for more ideas.

Hope this helps. I have solved this problem. We can you %%.abc or ^%.abc as you said.
