PSM_ISDIALOGMESSAGE message

Passes a message to a property sheet dialog box and indicates whether the dialog box processed the message. You can send this message explicitly or by using the PropSheet_IsDialogMessage macro.

Parameters

wParam

Must be zero.

lParam

Pointer to an MSG structure that contains the message to be checked.

Return value

Returns TRUE if the message has been processed, or FALSE if the message has not been processed.

Remarks

Your message loop should use the PSM_ISDIALOGMESSAGE message with modeless property sheets to pass messages to the property sheet dialog box. On systems that support Unicode, use the Unicode versions of the GetMessage and PeekMessage functions (GetMessageW and PeekMessageW) to retrieve messages.

If the return value indicates that the message was processed, it must not be passed to the TranslateMessage or DispatchMessage function.

Note

This message is not supported when using the Aero wizard style (PSH_AEROWIZARD).
