How to access the main window when a child window exits a process in C #

Question

I am running an application in C # via Process.start (). when this application opens, a child window is initially launched to try to connect to the simulator equipment. until the child window can connect to the equipment, the child window will remain in focus, and the main window will remain in the background. as soon as the child window successfully connects to the simulator hardware, I want to send the strokes of the keys to the main window. so I want to know what time it took to connect it to the hardware, as well as to capture the child window. can anyone let me know how to do this if possible?

Answer 1

makes Process.MainWindowHandle not suitable for your needs.
