You need to SendMessage/PostMessage Windows messages to the target HWND. You may also need a CBT hook depending on how you want to manipulate the behavior of the destination window.

See this article on this topic:
Manipulating Windows using messages and simple CBT hooking[^]

(apparently lots of people are trying to do this nowadays, this question comes up very frequently).
