ORASADFUNC callback function (ras.h)

The ORASADFunc function is an application-defined callback function that is used to provide a customized user interface for autodialing.

This prototype is provided for compatibility with earlier versions of Windows. New applications should use the RASADFunc callback function. Support for this prototype may be removed in future versions of RAS.


ORASADFUNC Orasadfunc;

BOOL Orasadfunc(
  HWND unnamedParam1,
  LPSTR unnamedParam2,
  DWORD unnamedParam3,
  LPDWORD unnamedParam4






Return value

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

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


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

To enable an ORASADFunc 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 szAutodialDll member specifies the exported name of the handler.

The ORASADFunc function is a placeholder for the library-defined function name. The ORASADFUNC type is a pointer to an ORASADFunc function.
