===========================================================================

 

用RAS操作ADSL。

 

①.RasEnumEntries 

The RasEnumEntries function lists all entry names in a remote access phone book.

 

②.RasSetEntryProperties 

The RasSetEntryProperties function changes the connection information for an entry in the phone book or creates a new phone-book entry.

 

函数原型：

 

DWORD RasSetEntryProperties(

  __in          LPCTSTR lpszPhonebook,

  __in          LPCTSTR lpszEntry,

  __in          LPRASENTRY lpRasEntry,

  __in          DWORD dwEntryInfoSize,

  __in          LPBYTE lpbDeviceInfo,

  __in          DWORD dwDeviceInfoSize

);

 

第三个参数参照MSDN。

 

除了上面（MSDN）说的几个成员需要提供外。

还有

dwSize 推荐：sizeof(RASENTRY)-------------此成员不设置函数会返回632

dwfOptions2 推荐：RASEO2_Internet---------见图2.

dwfNetProtocols 推荐：RASNP_Ip------------见图1.

 

对于要求的dwfOptions 推荐：RASEO_RemoteDefaultGateway（见图2.）|RASEO_ModemLights（见图3.）

 

③.RasDial 

The RasDial function establishes a RAS connection between a RAS client and a RAS server. The connection data includes callback and user-authentication information.

 

④.RasEnumConnections 

The RasEnumConnections function lists all active RAS connections. It returns each connection's handle and phone-book entry name.

 

⑤.RasHangUp 

The RasHangUp function terminates a remote access connection. The connection is specified with a RAS connection handle. The function releases all RASAPI32.DLL resources associated with the handle.
