获取窗口的句柄

Question

I have a window which runs in separate thread. I need to get the handle of that window in another thread.

I can't use ::FindWindow API, because the window name will change, as my application can run in other languages. Plus, I don't have access to the resource string used for window name.

I can't use ::GetActiveWindow also, as the calling thread id and the active window thread id is different.

Please suggest some solution.

It is not necessary to pass the window name to the FindWindow function. You can pass NULL for the window name and find the window using only the lpClassName parameter.

MFC normally assigns window class names automatically, but you can control a window's class name by registering a unique name with AfxRegisterClass and creating the window with that registered class name.
