Like I said, the simple example I put together worked fine for me so it seems clear that there's a detail which is missing that accounts for the behavior you're seeing. Did you try that example? If you need me to, I can send the code, though it just invokes 'ssh' as you describe via 'system()'. If you can point to how your example is different than mine or provide a simple example that shows the problem, that might help. >> At 01:03 PM 8/3/2004, you wrote: >>>Hello list, >>> >>>I am writing a program in C# that calls some cygwin programs and >>> redirects >>>the standard output and error to a textbox.
