Solve : Executing process at intervals??

Answer»

Hello,
I have a doubt in Windows batch programming,

Straight to the point, how to run a program at regular interval?

I have a batch script[Check.bat] which checks for a process in the running list, if it is running then the program quits, else the program shuts down the system.

Now I need another script which launches 'Check.bat' at every 1 minute.

Can anyone help me please!Task schedulerI tend to hard code this into the program, so instead of STARTING and stoping, it just performs it's task every minute instead of exiting. This allows you to drop it in the background and not have to worry about a little black window popping up all the time.

Code: [Select]@echo off
REM this sets %m% equal to the minute of the current time.
set m=%time:~3,2%
:loop1
REM this will add 1 to the minute, telling it when it should stop
set /a m+=1
REM this stops it from waiting for 1:89:00 AM :D
if %m% EQU 60 set m=0
:loop2
REM this waits for the minute to equal whatever %m% is equal too, in this case, it is the minutes +1 from the last time you passed loop1
if %m% EQU %time:~3,2% goto yourProgramCode
REM this sends you back to loop2, making sure that you can only exit the loop when the time is correct
goto loop2

:yourProgramCode
...
...
...
REM this goes back to loop1 to add 1 to %m% and to wait a minute
goto loop1
As long as your program doesn't take over a minute to complete, then this should WORK. If it does, then you'll have to change the code a bit to refresh at loop1 to =%time:~3,2% instead of +=1. Hope this helped.

EDIT: Fell free to remove the lines that start with "REM" if it hurts your eyes.This is dependent on on your regional and language settings. Not everyone displays the time and date the same way.

7552.	Solve : sending output to /dev/null?
Answer» I write script in ksh and am trying to do something we do regularly, that is send the out put of a command to null, i.e. we use 2>/dev/null in unix. Is there something like this that can be used in a .bat file. I am using cacls on a directory and it SENDS all kinds of output to the dos WINDOW, I WANT to GET rid of that. Thanks!Pretty much the same in the Windows world. cacls 2>nul Use 1 to REDIRECT STDOUT Use 2 to redirect STDERROR Hope this helps. 8-)So obvious!! Thanks!

7553.	Solve : Trouble with erase C: and format C:?
Answer» My laptop is really messed up. I have a Sager 9880. Here is my problem In "run" I type in format C: It says all data will be lost and i type in Y. Then it says "Format cannot run becasue the volume is in use by another process. Format may run if the volume is dismounted FIRST. All opened handles to this volume would then be invalid. Would you like to force a dismount on this volume? (Y/N) I type in Y. Then it says Cannot lock the drive. The volume is still in use. What do I do? It is on the drive that windows XP is on. Windows XP came installed on the computer. When i try to run and reinstall windows from the xp restoration cd, I GET another error after I press I agree. It says something about an error and the system must shut down. Run Chkdsk, and check if there is enough space. There is 8GB rmaining so it should be OK right. Please help and Thank You.You cannot format drive C while you are running from it. That will never work. You EITHER need the appropriate boot disks, or a bootable O/S CD, like the XP CD. You need to make SURE your computer has the OPTION of booting from CDROM first (it should) then just restart the machine with the CD in the drive and follow the prompts.

7554.	Solve : Embed into an echo command?
Answer» Hi: I am TRYING to do what I thought would be easy... and for some reason it is not. Here it is... I am trying to create SQL scripts for a file using the ECHO command. All is fine until I reach... echo IF (@Status <> 0 or error <> 0) it sees the <> as an attempt to redirect output ERRONEOUSLY. If I PUT quotes around the STRING, it will mess up the SQL. Any thoughts? You have to use ^ to mask <>\|... echo ^> should work hope this helps uli

7556.	Solve : hide command prompt of a batch file?
Answer» I want to know the code which can hide COMMAND prompt when the batch file is INITIATED. Even if it happens in the background but not seen to the user is also okay for me.But the INTENTION is that the user must not know a batch file is executing when it is initiated.At the command prompt type START/? and have a look at the /MIN parameter. Does this do it for you??? Please mention your OS when posting...

7557.	Solve : Please help me with the batch script?
Answer» I am a newbie to windows batch script. I ATTEMPTED to complete the following requirements, but, keep getting errors I have 3 files in C:\START folder. I WANT to copy only one file depending on the input from user into C:\END folder as end.txt. The destination file name is the same irrespective of the file to be copied. I have been trying to get this done. Unfortunately I need to do this by end of today. Please help me. Here are more details 1) Before copying each file from C:\START folder, display the filename and ask the user input 2) when user enters 'y' promt him again ask "are you SURE?" if user enters 'N' display the next file and so on.. 3) Once user enters 'y' again. move the file into C:\END folder as end.txt if user enter ''N' disply the next file and so on.. 4) CAPTURE the file name which got copied and delete it from server where it ACTUALLY came from So you want us to do your homework for you?

7558.	Solve : Help with looping and user files?
Answer» Here's my situation.... I have 5 servers (A, B, C, D, E). I need to transfer files from SERVER A for mutilple users to the other 4 but only if the folder doesn't exist. So I am looking for a way to read through multiple users C:\Documents and Settings\%Username%\Local Settings\Application Data\Microsoft\ on server A and copy the Outlook (and all pst files within it) folder to C:\Documents and Settings\%Username%\Local Settings\Application Data\Microsoft\ on servers B, C, D, and E if they don't exist (which also means the Outlook folder will need to be created. Anyone know of a way to tackle this? THANKS for any and all helpExternal DOS is out of the question if the drives are NTFS formatted and it may well be difficult if the user accounts are private. If you can get a script to RUN it would probably be easier to SET variables for each user or folder and use if exist/then, if not exist/then etc statements.

7559.	Solve : net send?
Answer» hey i'm a complete newbie and i was just wondering what the NETSEND command is and how it works. Also i was wondering if there is any way into a command PROMPT that has been disabled by an administrator and if so how. (this stuff is probably way over my head) Thanks anyonehttp://www.ss64.com/nt/net_send.html hope this helps uliNetsend can be used to send messages between networked COMPUTERS. The messenger service must be turned on for both MACHINES before the service will work, u can turn the messenger service on by opening run and directing to services.msc you can write a batch file to use netsend if it doesnt appear on your START menu. it depends if your administrator has actually disabled cmd prompt or simply removed from the start menu. something like {net send nameofcomputer "message u want to send" will work}thanks HEAPS guys that will really help

7560.	Solve : Help with Opening a File?
Answer» I have created a program in Visual Basic .NET, that opens up the COMMAND prompt window. I am telling it to open a CERTAIN file. The file opens, but I the command prompt window closes automatically. It is a .CLASS file I am opening. Are there any commands to force the window to stay open? Thanks

7561.	Solve : Help for for loop ( basics concepts of Batch)?
Answer» Hi, I am new to batch programming. I have a requirement where in I have to one map to a server and change the password for a product installed on that server there are more then one product on that one server. I need some basics to get clear for /f %%I in (dctm5dev.INI) do call change_dctm_passwd.bat %%I %1 %2 can some help me to get some tutorials which has these commands like for /f ( i dont know the meaning of /f but i can guess from the code that its says for each line in the file ........ but i want to know the correct meaning .... no guesses) similary for /f "tokens=1,2" %%I in (%dctm_server%.ini) do call change_db_passwd.bat %%I %%J i would like some one ot tell me how does token things work. Any help would be appreciated Raj The FOR command can be used for parsing, running a command repetitvely or reading input or depending on how it's written any combination thereof. They can also be NESTED. Note: %% variables do not exist outside the scope of the FOR statement. The /f switch indicates what data format the FOR statement will be acting on. for /f %%a in (file-set) for /f %%a in ('command') for /f %%a in ("string") Note the use of the quotes. (no quotes is a file-set; one quote is a command; two quotes are a string value) The tokens are stranger animals. In general they are sequenced single letters (case sensitive, %%a is not the same as %%A). The first token is the one you use in the FOR statement, the others are relative to their sequence in the alphabet. Example: for /f "tokens=1-3" %%a %%a is token 1 %%b is token 2 %%c is token 3 for /f "tokens=1-3" %%i %%i is token 1 %%j is token 2 %%k is token 3 It gets even stranger if you skip a token: Example: for /f "tokens=2-3" %%c The first value exists, but it's second value that is assigned to the %%c token. Typing FOR /? might help, but the Microsoft EXPLANATION is more convoluted than mine. Depending on your OS, there are other switches (/D, /L, & /R) and then there is skip= and delims=. Good LUCK. 8-)

7562.	Solve : copying only files and not the directory structure?
Answer» I am trying to figure out a way to copy FILES from a multi structured directory such as EXAMPLE (c:\dir1\dirA\dirB\.) to another directory copying only files and not the directory structure such as going from c:\dir1\dirA\dirB\. to c:\dirC. This would also have to take into concideration that the directory structure constantly changes. ANY IDEAS??? PLEASE HELPWithout you MENTIONING an OS, I can only guess, but this may work: Code: [Select]@echo off for /f "tokens=1" %%i in ('dir /b /s /a:-d c:\dir1\.*') do copy %%i c:\dirC Hope this HELPS. 8-)

7590.	Solve : Nslookup from an IP list - Batch??
Answer» Hello, I have used this formum for a long time now, but am finally registered to ask a question. Soon I hope to help provide feedback to people too. My question is this though, can anyone think of a way to create a batch file to do the following: 1. Input a list of known computer names 2. USE nslookup to find each computer's IP address 3. Output each address into a seperate file I know that may seem like a lot to ask for the first question, but I am drawing a blank here. My main problem is the output I currently get this: C:\>nslookup SERVERNAME.com Server: mydns.com Address: xxx.xxx.xxx.xxx Name: SERVERNAME.com Address: xxx.xxx.xxx.xxx [highlight]<-----THIS IS ALL I WANT[/highlight] Aliases: SERVERNAME2.com Any thoughts??To find just the ip address, you can pipe the output of Nslookup to the find command. nslookup www.google.com \| find "Address" this SPITS you out more than just the address, so you need to configure it a bit more. From the initial nslookup, figure out what the IP of your computer's nameserver is. (you said mydns.com in your example) So now we can eliminate that field's address nslookup www.google.com \| find "Address" \| find /v "xxx.xxx.xxx.xxx" That should POP your answer out in one of two ways. 1. Address: xxx.xxx.xxx.xxx 2. Non-authoritative answer: Address: xxx.xxx.xxx.xxx I haven't figured out how to get rid of the Non-autoritative answer: yet, but I hope this gets you going in the right direction. As far as how to get these into separate files, I would write a simple vbscript that reads from a file and loops through EXECUTING this batch file untill all addresses are used.This should do the job: @echo off set pclist=your list with the machines for /f %%a in (type %pclist%) do call :SUB %%a set pc= goto :EOF SUB: %%a set pc=%1 for /f "skip=1 tokens=1,2 delims=:" %%a in ('nslookup %pc% ^\|find /i "Address"') do echo %%a%%b >%pc%.txt :EOF hope this helps uli

7563.	Solve : DOS Loop?
Answer» I went into DOS and can't get out! Whenever I TYPE in 'exit' or 'win' it just restarts then goes back into it. I have a '98 and it is old, but it still operates pretty well. It loops back into DOS. Can anyone HELP? :-?Did you boot into Dos or open a Dos window?? On a reboot does Windows start or does pc boot into Dos??? Did you make any changes while in Dos??? What is selected on the Shutdown menu???Try these two options: At the DOS prompt type cd\windows then win Reboot and hold down the ctrl KEY while booting. This should bring up a boot menu. Select "normal" boot.I tried the cd/windows (enter) then win (enter) then holding down ctrl. It only put me right back into DOS mode. I rebooted into DOS and didn't make any changes. There also isn't a shutdown menu. My computer boots into DOS too. Hope that helps, caus' I don't have a clue!;DHey, I figured it out! Holding down ctrl during the startup then hitting the step-by-step process of chosing what drives to start (I think option #5 or #4). I clicked 'no' to all of the DOS drives or anything with DOS in the name. It then started up 'normal!' Well, it only took a good five hours of my life, but...oh well. What can one do.

7565.	Solve : Check Filesystem with .bat-File?
Answer» Hello! At first I want to note that I'm not a native english speaker, so please forgive me MISTAKES in the grammer. Now to the Problem: I have to check if the FileSystem is Fat32 and when it is Fat32 then he should do something. Like in stupid language If Filesystem = Fat32 ( START program1 )else( start program2 ) Is that possible WITHOUT creating some files? And how could I do that? THANKS for your help! FJThere are more efficient ways to do this, but this should work: Code: [Select]@echo off for /f "tokens=1-8" %%a in ('chkdsk DRIVE: ^\| find /i "file system"') do ( set filesys=%%h ) if filesys==NTFS .... if filesys==FAT32 .... if filesys==FAT .... Note: Change drive: to the drive you are checking. Hope this helps. 8-) Thank you! Does I need something? Only chkdsk.exe or?

7567.	Solve : Copy new files?
Answer» Hi everyone, I need to copy newly created files from a FOLDER to a folder on another server. I am planning to schedule this as a job in a batch file to RUN everyday during night. The problem is how do i findout when the file is created. I need to copy only new files that are created on the day the script is running. Any ideas any help, MUCH appreciated.. Thanks a lot.Without an OS I can only guess. This may work on your machine: CODE: [Select]@ECHO off for /f "tokens=1-2" %%a in ('date /t') do set datem=%%b for /f "skip=5 tokens=1-5" %%i in ('dir /tc /a:-d yourdirectorygoeshere') do ( if %%i==%datem% copy yourdirectorygoeshere\%%m destinationfolder ) Change yourdirectorygoeshere and destinationfolder to something appropriate. All bets are off if this runs after midnight :-/

7569.	Solve : Boot dos from hard drive?
Answer» I need to know which files I need to boot dos from a hard drive. I booted from a floppy proceeded to fdsik/mbr then fdisk then formated and made a partition active. I then copied auto.exec.bat, command.com and config.sys to C:\.......I get a error select proper boot disk ....what am I missing to boot my drive to dos so it comes up c:\> Thanks Deweyit isn't auto.exec.bat, it is autoexec.bat. That may be your problem, also, check for other codes that may be typed wrong.That was just a typo I have the file name right GaryI guess you could just copy all the files on the boot disk to c: but if you want dos then you will need to install dos.Have you tried entering SYS C: at the A: prompt to transfer the system files from the boot floppy to your hdd to make it bootable??? You could also have used the S PARAMETER of the Format command to do the same (Format c:/s) Which bootdisk are you using???The syntax may need to be sys a: c: in some instances. EASIER still would have been to format it as a system drive in the BEGINNING - format c: /s Config.sys and autoexec.bat aren't NEEDED to "bare boot".That is what I am doing I have done it before and cannont figure out what I am doing wrong. I use this to teach a group of kids about basic dos commands. I have removable hard drives that we have formated with the /s switch we then made a dir called dos and put the commands we are working on in the dos directory. The Autoexec.bat points to the dos directory. I just can't get the hard drive to just boot to a command prompt without the floppy.. These drives had linux on them before we started so we did a fdisk /mbr then a format with the /s switch. Did I miss something? Thanks for the sounding board. DeweyIf you have other filesystems than FAT on you HD you should delete the partitions with fdisk after fdisk /mbr -fdisk /mbr fdisk (delete the existing partitions) (create a new partition) then format c: /s hope this helps uliWe did delete all partitions using fdisk and made a new partition that we formatted..Thanks for the help I copied the system files from the floppy to the hard drive as suggested above A:>sys a: c: and it now boots as needed. The other item that was missing was that I had neglected to set our new partitions as active. Thanks again to those who responded. Dewey

7571.	Solve : net send, batch file and my question!!!?
Answer» whats up everyone! now, everyone knows the NET send command? rite and some know there is a batch file that goes like this: @echo off :A Cls echo MESSENGER set /p a=USER: set /p b=Message: net send %a% %b% Pause Goto A and when you run it, it asks for the user, and the messege but i want another type of batch file instead of a net send batch file i want a "for /L %i IN (1,1,150) DO net send IP_ADDRESS_OR_NETWORK_NAME %i" batch file "for /L %i IN (1,1,150) DO net send [IP_ADDRESS_OR_NETWORK_NAME] %i [message]" is a command that you use to send the number of messeges alot of time (in this case 150) but i need someone to do a batch file that asks you for the user to send it to and the messege but i want it to ask the number of TIMES... i did one but did not work... and here is how it looks @echo off :A Cls echo MESSENGER set /p a=User: set /p b=Message: set /p c=Times: for /L %i IN (1,1,%c%) DO net send %a% %i %b% Pause Goto A thanks for your help and timeIt's just a question of playing the percentages. Code: [Select]@echo off echo MESSENGER set /p a=User: set /p b=Message: set /p c=Times: for /L %%i IN (1,1,%c%) DO net send %a% %%i %b% Why do you want to send multiple MESSAGES to the same user? Don't answer that, I don't REALLY want to know. Good luck. 8-)thanks, u da best

7573.	Solve : automate conversion of mp4 files to mp3?
Answer» OK I'm totally at a loss on how to word this so I'm just going to write it out the best that I can... First I have a batch file that I'm writing that will convert mp4 files to mp3 files (I have a lot) for a buddies band using ffmpeg. Here's the CODE that I'm using: ffmpeg -i folder\video.mp4 -f mp3 -ab 160000 -vn "\different folder\music.mp3" what I would like to do is add to this so that I don't have to write out this code for every file I have... :/ I have the mp4 files in one folder and than the mp3 files are saving to another folder. So here's an example of what the code will do if it isn't clear yet. Folder 1: video1.mp4 video2.mp4 video3.mp4 what it should do is grab video1.mp4 and convert it. ffmpeg -i folder\video1.mp4 -f mp3 -ab 160000 -vn "\different folder\music1.mp3" and than move onto the next one ffmpeg -i folder\video2.mp4 -f mp3 -ab 160000 -vn "\different folder\music2.mp3" and than the next one ffmpeg -i folder\video3.mp4 -f mp3 -ab 160000 -vn "\different folder\music3.mp3" It's going to have to grab the name from the mp4 file and insert it for the mp3 file. Here's what I have so FAR... Code: [Select] @echo off dir /s /b "C:\Users\username\Desktop\Music Stuff\Videos\." > "videolist.txt" dir /b "C:\Users\username\Desktop\Music Stuff\Videos\." > "musiclist.txt" for /F "tokens=" %%A in (videolist.tmp) do SET video= %%A for /F "tokens=" %%A in (musiclist.tmp) do set music= %%A ffmpeg -i "%video%" -f mp3 -ab 160000 -vn "%music%".mp3 PAUSE del videolist.txt musiclist.txt [CODE] I can get around pretty good in cmd if it's basic commands but when it comes to something like this I'm a little confused... Thanks for the help in advance! I'll SEE what i can do about searching some more on what I would have to do and if I find the solution I'll post it here if it isn't already answered.Try something like this: Code: [Select]@echo off for /f "delims=" %%A in ('dir /b "C:\Users\username\Desktop\Music Stuff\Videos\."') do ( ffmpeg -i "%%~A" -f mp3 -ab 160000 -vn "\different folder\music_%%~nA.mp3" ) pauseThat should work for you, but I can't exactly test it because I don't have ffmpeg.Wow that's so much simpler than what I had and it works flawlessly! I've spent the last two days trying to figure it out I was making it way more complicated than it needed to be... Thank you SO much!

7582.	Solve : Need major help in cresting Batch File to carry out a procedure?
Answer» The batch file has the following requirements. The information should be logged either to a file on a removable device, or to a remote server using netcat. This can most easily be done by redirecting the command line. The batch file should not require any special software to be installed on the suspect PC. It should run from a CD or USB drive and be ENTIRELY self-contained. However, for this practical it is not necessary to set up assemblies -- the system DLLs and utilities can be used. Commands requiring administrator ACCESS may be used, but the batch file should not fail if run as a NORMAL user. Most information should be captured using standard Windows utilities and the Sysinternals tools, as appropriate. Can ANYONE help me with this/?Sounds like homeworkPart of my assignment yea and i need help with it

7583.	Solve : dos commands not recognized?
Answer» :-? I am running windows 98 and i have a home built cpu. I have been having dos COMMAND issues. Could not get it to defragment. Then I think I picked up a virus or two of my autoexec.bat files got corrupted. himem and win.com. Now at the dos command line it gives me a MESSAGE when I type "edit autoexec.bat" I get BAD command or filename as the response. It doesn't RECOGNIZE the format disk command either. It will let me list the dir and cd. I'm not 100% computer savvy but I'm not computer dumb. Please help. Use the cd & dir commands to check the location & existance of the files that won't run.Both Dir and Cd are internal commands for Command.com, Edit and Format are external (UTILITIES). So you can Dir and Cd all you like but you have to set the path to where Edit and Format reside. Can't be sure but think that in 98 Edit & Format are in C:\Windows\System, I'm sure you can find them - do a search and set your Path to suit. Good luckWin.com should be located in c:\windows Edit and Format should be in c:\windows\command Both directories should be in your Path statement

7584.	Solve : Linux hostname from IP?
Answer» I'm using XP. I can USE nbtstat -a to get the HOSTNAME of a windows machine from the command prompt. Am I able to get the name of a Linux box from the command prompt knowing only the IP ?Why do you need to do this ? ?Work related.How much is the solution worth ? ?Why the hard time? I'm just wondering if there's a WAY to do it from a Windows command line instead of having to walk over to the servers.Unfortunately, I don't know of anyway to check the OS on a remote system through batch. Is it possible that you can implement a naming convention that would allow you to tell just from the name whether it was Linux or not? If so, that may be a route to pursue. The command I know that would hold the OS would be systeminfo. Also, the %OS% variable in cmd environment would tell you that it was Windows_NT. Obvioulsy, these wouldn't do much good without having access to the cmd environment though. Sorry I couldn't be of more help. I don't run a mixed OS environment myself, but have heard from those who do that identifying the OS in the computer name is the most efficient way of managing things. I would suggest it (or INSTITUTE it if you have that authority) as from what I have found, it is an accepted best practice.

7592.	Solve : How to create Batch file to search for latest files in a folder??
Answer» Hi all, I got this Folder that consists of the following files: A_B_C_2012-03-29-09-20-21.xls A_B_C_2012-03-28-09-20-12.xls A_B_C_2012-03-28-09-20-05.xls D_E_F_2012-03-29-09-10-22.xls D_E_F_2012-03-28-09-10-11.xls D_E_F_2012-03-28-09-10-04.xls I want to create a batch file to copy out the latest ABC and DEF Files in the same folder. I have created a batch file @echo off setlocal set source=z: set destdir=c:\test pushd "%source%" for /f "tokens=" %%a ('dir A_B_C_.* /b /a-d /o:e 2^>NUL') do (set lfile=%%a) echo copying "%source%\%lfile%" to "%dest%" copy /y "%source%\%lfile" "%dest%" This code works FINE to extract out the latest A_B_C_ file, but when i create another batch file to extract D_E_F file, i always got an error prompt, File Not Found. Codes for D_E_F: @echo off setlocal set source=z: set destdir=c:\test pushd "%source%" for /f "tokens=" %%a ('dir D_E_F_.* /b /a-d /o:e 2^>NUL') do (set lfile=%%a) echo copying "%source%\%lfile%" to "%dest%" copy /y "%source%\%lfile" "%dest%" Any advises?When posting code please USE the code tags to increase readability. ALSO it might be better to copy/paste your actual code. The code you posted has numerous syntax errors. The only real flaw in your logic was the sort sequence. You were sorting on extension rather than file name. Other than that, it works like a CHAR,m. Code: [Select]@echo off setlocal set source=z: set destdir=c:\test pushd "%source%" for /f "tokens=" %%a in ('dir A_B_C_.* /b /a:-d /o:n 2^>nul') do set lfile=%%a echo copying "%source%\%lfile%" to "%destdir%" copy /y "%source%\%lfile%" "%destdir%" for /f "tokens=" %%a in ('dir D_E_F_.* /b /a:-d /o:n 2^>nul') do set lfile=%%a echo copying "%source%\%lfile%" to "%destdir%" copy /y "%source%\%lfile%" "%destdir%" I combined the code into a single batch file but you can separate it if necessary. Good luck. You are MISSING a percent sign in your copy command.

7598.	Solve : Unzipping to a temporary file and open and delete it?
Answer» Dear all, I'm a newbee or a noob with programming. I need a BATCHFILE wich does the following: - Unzip a file from a zipfile (using winzip32.dll) - the unzipped file must be a temporary file - the unzipped file must be opened in Excel - after closing the tempfile... the file must be deleted Until now I found this code/files on internet: filename: CreditDB.vbs containing the following code which unzips the file: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - strZipFile = "path\Some zip-file.zip"'name and path of zip file, which CONTAINS only 1 file: Some excel-file.xls outFolder = "C:\temp" 'destination folder of unzipped files 'Create the required Shell objects Set objShell = CreateObject( "Shell.Application" ) 'Create a reference to the files and FOLDERS in the ZIP file Set objSource = objShell.NameSpace(strZipFile).Items() 'Create a reference to the target folder Set objTarget = objShell.NameSpace(outFolder) intOptions = 256 'UnZIP the files objTarget.CopyHere objSource, intOptions 'Release the objects Set objSource = Nothing Set objTarget = Nothing Set objShell = Nothing - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - CreditDB Launcher.bat containing the following code to open the unzipped file: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - cscript //nologo "path\CreditDB.vbs" 'name and path to vbs-file (see above) START EXCEL.EXE "C:\temp\Some excel-file.xls" 'path and name of unzipped file (see above) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - The problem is, that the unzipped file may only be veiwed by the user that unzipped it. But when one unzips a file to C:\temp that everyone else who logs onto the PC can view this file form C:\temp. So, I need the code to delete the file after it has been closed, but I don't have a clue where to start. Hope SOMEONE can help me

7599.	Solve : How to delete a very very very large Badmail folder?
Answer» I had a virus on my windows 2003 server. It was sending out MASS emails most of which were coming back to the bad mail folder. I have removed the virus, but in the meantime the bad mail folder was filling up. The only thing I could do was to rename the folder. Before I had finished removing the virus I had 2 folders that were renamed with thousands and thousands of files. I have tried all the normal rmdir, del ., ect all that seems to do is lock up the server. The REAL problem I have is the only way I can access cpu is by remote access. Is there a way in DOS to delete files in batches "something like delete 1000 files at a time". Any help on this would be great. I hope all this makes sense.Have you tried BadMailAdmin? http://support.microsoft.com/kb/867642 I once fixed a "Can't send email" problem for a customer, because there were over 10,000 OLD emails stuffed in the Sent Items folder. I just tracked it down in Windows Explorer, right clicked on it and hit DELETE. In just a few seconds, the folder was gone and the problem was solved. The email program remade that folder the next time it ran. Good Luck,
