I am creating window inside my program, then sending HWND of this window to another application. Will drawing on window's HDC be valid for another process?

Windows are owned by other windows, not by processes. You can draw to any HWND on your desktop (at least if the window has the same integrity -- I'm not sure what happens if they don't).

Web browsers that host plug-ins or tabs in a separate process generally make use of this functionality.

Unfortunately you can do this.
