how to get a window's direct child ( not any grandchildren) in win32?

just the direct child, 开发者_Python百科not grandchildren.

GetWindow(hwnd,GW_CHILD); seems to be the trick.

This snippet could help!

    HWND hChildWnd;
    long childCount = 0L;

    hChildWnd = GetWindow(hWnd, GW_CHILD);
    if(IsWindow(hChildWnd)) {
            childCount ++;
        while(hChildWnd){
            hChildWnd = GetWindow(hChildWnd, GW_HWNDNEXT);
            if(IsWindow(hChildWnd))
                childCount ++;
        }
    }
