I want to know how can we run a bat file when a specific application is opened?
Eg: I would like to run a bat file whenever mspaint is opened.
I have successfully performed this in Windows 7 and Windows 10 using Task Scheduler. But the task scheduler available in Win Xp is very basic.
You could use another batch file that runs on startup of windows. use while loop with an appropriate sleep to detect when Paint.exe runs.
then you could write more commands to do anything you want. For example, as you said, you could run another batch file...
I found this solution by an investigation of these topics:
Syntax for a single-line Bash infinite while loop
How to check if a process is running via a batch script
Batch program to to check if process exists

I've managed to run the script from the command line thinking that i could possibly use windows Schedule Task to run it, but it doesn't run command prompt or anything. When i go and check the task it says it completed. Im running windows8. Any help would be appreciated.
You can make a .bat file to execute your sikuli sript. .bat files can be scheduled with Windows 8, but you may need to schedule that task as SYSTEM or as the admin.
I have a startup task for my webrole that download some executable file from a blob and then proceed to the installation.
From a .cmd file, I start a power shell script that download the files, then I start the file from the .cmd.
The script works fine if I run it manually through RDP after the publishing is done.
But, when running as startup script, it sometimes (often) fail at different points.
The taskType is set to background.
Last time, the error was that the command PowerShell does not exists...
Also, I use powershell -command set-executionpolicy unrestricted before running my PS script, but I read here that other task may reset this setting and make mine fail.
Quite a mess.
So that makes me think that if I could wait for all other task to perform before starting mine, it would eliminate these kinds of problems
I suppose I could check if some process is running and wait for it to finish, but I have no clue wich process to check.
Or maybe there's another solution.
~edit~
I read here that the error about powershell not existing may be caused by the batch file being saved as UTF-8 in visual studio. I re-writed it from scratch in notepad++ and made sure it is save as ANSI. Then, same error. The full message is :
'PowerShell' is not recognized as an internal or external command,
operable program or batch file.
Again, the script run perfectly from command line in remote desktop.
It would be possible to set an environment variable at the end of the script that is required to finish, then in the script which is awaiting the dependencies, loop until the environment variable is set, then kick off its activities.
You could also run everything from a single powershell script and use the '-asjob' switch on your installer statement, use the 'wait-job' cmdlet to block until the task is complete then carry on. Powershell also offers a '?!' operator which ensures the last statement executed properly.
This might be caused by an encoding issue. As mentioned in this answer you should save your file in ASCII to ensure correct interpretation of your script.
From the linked answer:
Open your whatever.cmd file with your VS 2012 Ultimate. Click on File->Save whatever.cmd as -> on the dialog there is little arrow next to the [save] button. It will show up a menu that will have the option Save with Encoding.
Select it. Now choose "US-ASCII Codepage 20127" from the list of available encodings.
Let's say I have 5 batch files that run sequentially one after another (executed via the Windows task scheduler on a normal Windows XP PC):
Script1.bat
Script2.bat
Script3.bat
Script4.bat
Script5.bat
Suppose one of the scripts fail (an error condition is detected -- details on how this happens is not important for my question here). How do I stop the other scripts from running if they all run within the task scheduler? For example, if Script1.bat fails, I don't want to run Script2-5.bat. If Script3.bat fails, I don't want to run Script4-5.bat, etc.
I thought about writing a flag value to a temporary file that each script would read from. At the beginning of each script (except for the first one), it will check to see if the flag is valid. The first script would clear out this flag at the beginning each time these set of batch files run.
Surely there is a better way to do this or maybe there is a standard for how to handle this type of situation? Thanks!
Write a master.bat file that conditionally calls each of the scripts in sequence. Then schedule the master instead of directly scheduling the 5 scripts.
#echo off
call Script1.bat
if %errorlevel%==0 call Script2.bat
if %errorlevel%==0 call Script3.bat
if %errorlevel%==0 call Script4.bat
if %errorlevel%==0 call Script5.bat
I have a perl script that I run from the command prompt: 3 times a day, the problem is now I need to run it every two hours. Im not going to be on an episode of lost so I need some help. Here is the command:
Perl C:/test/scripts/edi.pl
Does anyone know how this above one line command can be made into an executable (.exe) file so I can use the task scheduler to run?
If there is another way to do this with the task scheduler to run once every two hours every day then I could do that as well.
Thanks for your time.
Can you not simply create a batch file that runs the script, and set that batch file to run every two hours? I know from a quick test there that I can schedule a batch file to run from Task Scheduler on Windows XP at least.
You can actually use the task scheduler to run that exact command without a batch.
The task scheduler should allow you to pass some arguments to the script without a problem (I have done this on a few Windows servers in order to have them run PHP scripts)
I have a windows batch file which I run to start a java application. The problem is that I don't want the command prompt output to be visible after the app starts. And not only that,... I don't event want to see it minimised. I don't want it at all. Any ideas?
Cheers!!
Use
start/b javaw.exe ...
If your program is not a console application, you can use START.EXE in your batch file to actually launch the real app. The initial console used to launch the batch file will be closed when the batch file ends.
You could actually probably launch the .bat file with start /b too in order to avoid all console windows.
