c# - How to find a child of a parent unmanaged win32 app

Question

Basically I am looking for a win32 method to invoke in C# to set the focus to a children of an unmanaged application.

But first I need to find the child control's handle which is the problem. Any useful win32 functions to solve this?

Answer 1

Use FindWindowEx to find the Handle of the Window you're looking for. Once you have that handle, use EnumChildWindows to find the correct child you need. There's too much code involved for me to quickly write up a sample, but there's enough on the web to help.
