How can I detect if a application has finished processing?

[Paco75]

Hi,

Im opening a external application and i must wait until it has finish processing before closing it...

I open the application thi way:

>dblProgramTaskID = Interaction.Shell("C:\Program >Files\Adobe\Acrobat 4.0\Distillr\AcroDist.exe >C:\WINNT\Temp\RequestPreview.txt", >VbAppWinStyle.vbMinimizedFocus)

the only way I have to wait is to use the following to do a five seconds pause:

>waiting = Application.Wait(Now + TimeValue("0:00:05&quot)

then after the application is closed this way:

>dblProgramTaskID = FindWindow(vbNullString, "Acrobat Distiller&quot
>Call SendMessage(dblProgramTaskID, WM_CLOSE, 0, ByVal 0&)

Is there a way to wait until the application has finished his procesing with something like a SendMessage?

thanks

The short answer is .. No.
I have worked with similar problems with applications using server access and it is a pig because the server response can vary considerably.

DoEvents does not seem to be any use whatever.

The only thing to do is experiment with the Wait statement.

Add forum222 to your list and search this site on "shell and wait" in your forums and you will find many examples that will allow you to shell out a program and wait on its completion.

Good Luck
