CWnd::SendMessage

LRESULT SendMessage( UINT message, WPARAM wParam = 0, LPARAM lParam = 0 );

Return Value

The result of the message processing; its value depends on the message sent.

Parameters

message

Specifies the message to be sent.

wParam

Specifies additional message-dependent information.

lParam

Specifies additional message-dependent information.

Remarks

Sends the specified message to this window. The SendMessage member function calls the window procedure directly and does not return until that window procedure has processed the message. This is in contrast to the PostMessage member function, which places the message into the window’s message queue and returns immediately.
