John,
the process receives no input. If I use C++ and WIN32-API CreateProcess
the process does not become visible.
The process is MS Word and I want it to work on a .doc-File that
contains VBA macro code. When finished, the VBA code will terminate
Word.
It works but Word is visible while working on the VBA macro. I came to
the conclusion that Process.Start may not handle the Hidden-flag
correctly. As a workaround, I am placing my own application window in
front of word. Later I will probably have to write a little C++ process
that handles starting Word.
Another solution would be to use the Word COM-objects instead of
starting Word as a new process. I do not really like that solution. It
creates dependencies I would like to avoid and an in-process COM object
may have adverse effects on my application. When started as an external
process, Word cannot hurt my application and I can terminate the
process if it behaves badly.
Anyway, thanks for your help.
Regards,
Paul Hoepping
