The operating system sends a WM_RASDIALEVENT message to a window procedure when a change of state event occurs during a RAS connection process, and a window has been specified to handle notifications of such events by using the notifier parameter of RasDial.

The two message parameters are equivalent to the parameters of the same names that are used with RasDialFunc and RasDialFunc1 callback functions.


rasconnstate = (RASCONNSTATE) wParam; // connection state about to be entered 

dwError = (DWORD) lParam;             // error that may have occurred 



Value of wParam. Equivalent to the rasconnstate parameter of the RasDialFunc and RasDialFunc1 callback functions. Specifies a RASCONNSTATE enumerator value that indicates the state the RasDial remote access connection process is about to enter.
Value of lParam. Equivalent to the dwError parameter of the RasDialFunc and RasDialFunc1 callback functions. A nonzero value indicates the error that has occurred, or zero if no error has occurred.

RasDial sends this message with dwError set to zero upon entry to each connection state. If an error occurs within a state, the message is sent again for the state, this time with a nonzero dwError value.

Return Values

If an application processes this message, it should return TRUE.
