RASADFunc info  Overview  Group

The RASADFunc function is an application-defined callback function that you can use to provide a customized user interface for autodialing.


    LPTSTR lpszPhonebook,

// pointer to full path and filename of phone-book file

    LPTSTR lpszEntry,

// pointer to the entry name to validate

    LPRASADPARAMS lpAutodialParams,

// pointer to a RASADPARAMS structure

    LPDWORD lpdwRetCode

// receives results of dialing operation



Windows NT: Pointer to a null-terminated string that specifies the full path and filename of a phone-book (.PBK) file. If this parameter is NULL, the function uses the current default phone-book file. The default phone-book file is the one selected by the user in the User Preferences property sheet of the Dial-Up Networking dialog box.
Pointer to a null-terminated string that specifies the phone-book entry to use.
Pointer to a RASADPARAMS structure that indicates how to position the window of your AutoDial user interface. The structure may also specify a parent window for your AutoDial window.
Pointer to a variable in which you must return a value if you perform the dialing operation. If the dialing operation succeeds, set this variable to ERROR_SUCCESS. If the dialing operation fails, set it to a nonzero value.

Return Values

If your application performs the dialing operation, return TRUE. Use the lpdwRetCode parameter to indicate the results of the dialing operation.

If your application does not perform the dialing operation, return FALSE. In this case, the system uses the default user interface for dialing.


When the system starts an AutoDial operation for a phone-book entry with a custom AutoDial handler, it calls the specified RASADFunc. Your RASADFunc can start a thread to perform the custom dialing operation. The RASADFunc function returns TRUE to indicate that it took over the dialing, or FALSE to allow the system to perform the dialing.

If your RASADFunc function performs the dialing operation, it presents its own user interface for dialing and calls the RasDial function to do the actual dialing. Your RASADFunc then returns TRUE to indicate that it took over the dialing. When the dialing operation has been completed, set the variable pointed to by the lpdwRetCode parameter to indicate success or failure.

Your AutoDial DLL must provide both a RASADFUNCA (ANSI) and a RASADFUNCW (Unicode) version of the RASADFunc handler. To enable a RASADFunc AutoDial handler for a phone-book entry, use the RASENTRY structure in a call to the RasSetEntryProperties function. The szAutodialDll member specifies the name of the DLL that contains the handler, and the szAutodialFunc member specifies the exported name of the handler. The szAutodialFunc member should not include the A or W suffix.

RASADFunc is a placeholder for the library-defined function name. The RASADFUNC type is a pointer to a RASADFunc function.
