I was trying to work up a working example,but ran into some roadblocks.. to
get a handle to that app, you can do this:
System.Diagnostics.Process[] procProcesses =
System.Diagnostics.Process.GetProcesses();
foreach (System.Diagnostics.Process procActiveProc in procProcesses)
{
if ( procActiveProc.MainWindowTitle == "whatever" )
{
// Do something - procActiveProc is a handle to that whole process now
}
}
But what I was thinking, was doing something like this:
procCmdWindow.StartInfo.RedirectStandardInput = true;
procCmdWindow.StartInfo.UseShellExecute = false;
procCmdWindow.StandardInput.Write("dir *.*\n\rdir");
But really, that is for when you create your own process.. I couldn't find
how to redirect stdin one the app is already running.. so, although I still
think this "can" be done somehow, I'm about out of ideas.
If nothing else, I've shown a way it *can't* be done!! :-) good luck!

How do you get the handle of the process. It is a seperate window.

Agreed, if you get a handle to the process, you could so something like:
objProcess.StandardInput.Write("this should show up in the console");

news:uu**************@TK2MSFTNGP11.phx.gbl... SendKeys.SendWait() works fine for a Windows app that I have to start
and then dismiss an initial dialog box -- even though my controlling app
is a console app.
I doubt it would work when *targeting* a console app however. Any
chance you could send the keystrokes to stdin instead?
