I have to shell out to a DOS app in the middle of my Win95 program. I
am able to start the DOS program, and I am able to wait until the DOS
program is finished. However, I do not know how to close the window
that is created for the DOS app.

Does anybody know the secret API call for this?

I'm calling the DOS program with the normal VB SHELL command using
vbminimized as the window state.

I'm using the GetExitCodeProcess API function to determine when the
app is done.

Thanks

Keep things the way they are, but change the command line for the DOS app
adding "command.com /c" in front, ie:

  x= Shell("\path\command.com /c " & DOSapp2start, 1)

This will start a copy of command com, and the /c tells it to close the
window when done.

You may want to use the environ$ method as well to assure the correct path
to command.com

Use the findwindow api call to locate the dos window that is open.
Once you have the hwnd for that window (The return value for
findwindow) use the PostMessage api call to send a WM_CLOSE message to
the window and it will close and cleanup after it self.

Hope this helps.

 Hi,

Take a look at the sample code I have in my site.
In the VB-Resumen look for: "Cmo saber si..." and you can download the
code.

Nos vemos.
