Bypass "Close Confirmation Dialog Box"

wballen

My VB program shells out to start an external EXE program which creates an open window. When I close this window in VB code, an "are you sure you want to close this program" confirmation dialog box pops up that must be manually closed. How do I do that in VB code?... to bypass or interrupt the dialog box? The code I am using to close the app is:

' The app may issue a close confirmation dialog
' depending on how it handles the WM_CLOSE message.
'
For i = 1 To colHandle.Count
glHandle = colHandle.Item(i)
Call SendMessage(glHandle, WM_CLOSE, 0&, 0&)
Next

Thanks for any help - wballen
