Thank you!Either renaming the script to a .pyw or launching the app with pythonw.exe got rid of the problem. So, the block of code exactly the same with a minor change as: [option 1] p = new Process() p.StartInfo.Filename = path/to/script //Here use a .pyw instead of a .py file p.StartInfo.Arguments = string_with_arguments p.StartInfo.CreateNoWindow = true p.Start() [option 2] p = new Process() p.StartInfo.Filename = path/to/pythonw.exe p.StartInfo.Arguments = path/to/script + any_string_args //(delimited by spaces as in the command line) p.StartInfo.CreateNoWindow = true p.Start() Thanks again, On Mon, Aug 17, 2009 at 7:38 AM, Maksim Kozyarchuk < mkozyarchuk@hedgeserv.com> wrote:

I am able to run a phyton script from C# using a code similar to:

p = new Process() p.StartInfo.Filename = path/to/script p.StartInfo.Arguments = string_with_arguments p.StartInfo.CreateNoWindow = true p.Start()

I am not interested in the script outcomes since the script just starts a Tk app with its own Gui.

The problem/annoyance I am having is when the process starts, it does so with a command window that points to python instalation location (so something like C:\Python25\python.exe) and just hangs there until I quit the Tk gui. Is there a way to get rid of this command window? If I close the command window manually, the Tk app closes as well.

Thank you for your help,
