Solution 1

You start with the Process class to get the Process instance you're looking for. Then you can use it's MainWindowHandle property to get the handle to the apps startup form.

[Adding to Dave's answer.]

You cannot use the handle returned from Process.MainWindowHandle with methods like Form.FromHandle because the handle is not already associated with a Control object in your application. Any interaction with that window will have to be through P/Invoking APIs like SetWindowText.
