C# Window functions with PID or Handle not Window Title

[Kenwa]

Using C#.

All my windows have the same title and there is no subtext. How can I use something like winactivate() with a PID or Handle instead of title text...

I already have the PID and Handle just need to know how to use the function or a similar function

Thanks

I'm working with random windows and only have the PID. Found this helpful:

Answer: Use this script.

$handle = WinGetHandle("[CLASS:ACTIVE]")
