WaitForSingleObject and DOS-Windows in Win98

I'm trying to start a DOS-Application under Win98
from Delphi with CreateProcess.
Further on I want to wait for the end of the
execution, using WaitForSingleObject.

The problem is, that DOS-applications as default
do not automatically close the DOS-window when
finished. So I have to close the window manually,
to make WaitForSingleObject detect the end of
the execution.

I used sw_hide - option to prevent from displaying
the DOS-window, but this does not help.

For normal applications the property can be set manally
with applications file|properties ..close.. (don't know the exact name in the english version...).

Can I simply change the default options for DOS-windows,
or can I use CreateProcess with special options to
close after execution end??


Thanks for help,

Gamba

When you initiate the DOS program prefix it with the following:

command.com /c <nameofprog>

This means that once the DOS program has finished executing it will close automatically (e.g. type "command.com /c dir" into the run command at the start button. WaitForSingleObject will pick up on the close then.
