Re: Terminating Running EXE
I know exactly what you mean Tantrum3k, I was in the same position you were before writing this myself and dis-regarding everyone's examples. I also have XP Pro SP2 so this should definately work for you. I'v commented it so you can really know what it is doing

Re: Terminating Running EXE
Will this also work for other versions of Windows? (Such as 98, ME, NT, 2K etc.)
Re: Terminating Running EXE
Kill App.path & "/myprogram.exe"

Re: Terminating Running EXE
That just deletes an .exe file, not stop a running process.

Re: Terminating Running EXE
You can not delete an exe if it is currently running. You get an error if you try.
Re: Terminating Running EXE
Also keep in mind that when you run an VB Exe normally it runs with the Logged in User credential, so if the process you want to terminate is a System Process then those API wont work unless the Logged in user is part of Administrator user Group.
Just thought I will point that out incase that is the cause of process not terminationg...

Add that to a module, then in your form do:
Code:
Private Sub cmdCloseApp_Click()
Dim blnRet As Boolean
blnRet = TerminateEXE("Woof.exe")
If Not blnRet Then
MsgBox "Terminate failed!"
End if
End Sub
Hope that helps.
I know the code above is a little messy.
If anyone wants me to tidy it up then I will.

Re: Terminating Running EXE
This is excellent!
I've been looking for a way to check whether a specific app is running or not, and act accordingly.
This code works fine - slightly adapted, using it as a Boolean Function

You are better off creating you own topic to ask the question is instead of hijack someone else's topic.
