Write/Draw Text in a foreign window

[dani.speh]

Hi,

I have a Simulation running that is closed Source, so that I can't
change anything in this programm. I would make some calculations and
put some (Text)-Results on the Simulation-Window. MY question is how
to put text (or graphics) on a window that's not a part of my VB.Net
Project. In C++ I would probably use GDI-Functions to draw in a window
but I'm not sure this is the right way. Are there any possibilities
in .Net to make this working

Tx Dani

I recently had a similar need, and wound up using sendmessage and
postmessage from user32.dll. Not sure about drawing a window, but
send/post message will allow you to "read" and "write" information
from/to existing objects/windows in another application.
