"What are you trying to do exactly ?"

An on screen grid contains a path and filename. A context menu has the function, "Open contaning folder". I'm simply tring to have the application open an explorer window with the folder in the grid as the argument.

I wasn't sure if it was something to do with the grid value I was passing it so I hard coded one, as above. Even a valid hard coded path produces the error, *after* the explorer window is successfully opened.

Is there a different/better method for running a process such as explorer.exe from within a C# program?

Thanks!
