how to execute console application from windows fo

Question

I want to run a console application (eg app.exe) from a windows form load event. I'v tried System.Diagnostics.Process.Start(), But after it opens app.exe, it closes it immidiately.

Is there any way that I can run app.exe and leave it open?

Answer 1

If you are just wanting the console window to stay open, you could run it with something like this command:

System.Diagnostics.Process.Start( @"cmd.exe", @"/k c:\path\my.exe" );

Answer 2

You have one of two problems, given your master/slave application setup:

1. Your master app is opening, displaying a form, that form runs the slave app and closes immediately, even though the slave app is still running.
2. Your master app is opening, displaying a form, that form runs the slave app which closes immediately.

For the first problem, you need to wait/block for the process to complete (i.e. Process.WaitForExit().

For the second problem, it sounds like the slave app has done what it needs to (or thrown an exception) and is closing immediately. Try running it with the same parameters from a command prompt and check the output.
