I always wondered about popularity of Winamp. It has rich custom drawn UI, which made it stand out of the crowd. Did you noticed its “Always on top” feature and wondered about how its implemented? Its time to reveal the secret – How winamp implemented that feature – Staying at the top?

SetTopMostWindow


You can use – SetWindowPos() with HWND_TOPMOST flag. Have a look at the code snippet.

void CRabbitDlg::OnSetTopmost()
{
    // Set window position to topmost window.
    ::SetWindowPos( GetSafeHwnd(),
                    HWND_TOPMOST,
                    0, 0, 0, 0,
                    SWP_NOMOVE | SWP_NOREDRAW | SWP_NOSIZE );
}


Single line of code. But wowing feature. isn’t it?
