Focus hWnd of another application

Is it possible to change focus inside a different application? I'm talking about the distinct views (data lists, custom views), not main windows. These also have handles, spy++ shows them properly and stuff, but when I've tried setting SetFocus(), is was no good. Does SetFocus() only work for main windows or what is amiss? Thanks

From the MSDN article:

The window must be attached to the calling thread's message queue

You'll need AttachThreadInput() first. GetWindowThreadProcessId() to get the thread that owns the window.
