- * IsDialogMessage
- *
- * This program demonstrates the use of the IsDialogMessage function.
- * The IsDialogMessage function is usually used in a window's message
- * loop to determine if messages are intended for modeless dialog boxes.
- * If a message it intended for the given dialog box, IsDialogMessage
- * processes the mesage for the dialog box. IsDialogMessage is called
- * from WinMain in this sample application
