This section describes how messages are processed by the default dialog procedure. The default dialog procedure can be called using WinDefDlgProc. A user dialog procedure should make this call for all messages that it does not want to process.

For WM_* messages other than those specified in this section the Default Dialog Procedure takes the same action and sets result to the same value as in Frame Control Window Processing. In the instance of messages that would be sent to FID_CLIENT, they are passed to the default window procedure.

For any other messages the default window procedure takes no action, other than to set reply to NULL.
