Just use SetTimer method, and pass two arguments: Timer ID (any number), and the timeout in milliseconds. Then write up OnTimer implementation, and an entry ON_WM_TIMER inside BEGIN_MESSAGE_MAP...END_MESSAGE_MAP.

CWnd::SetTimer takes 3 parameters, but only 2 are required. Pass third argument as NULL.

CWnd::OnTimer
