Method Detail

RasDial

int RasDial(WinRas.RASDIALEXTENSIONS.ByReference lpRasDialExtensions,
            String lpszPhonebook,
            WinRas.RASDIALPARAMS.ByReference lpRasDialParams,
            int dwNotifierType,
            WinRas.RasDialFunc2 lpvNotifier,
            WinNT.HANDLEByReference lphRasConn)

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

Parameters:

lpRasDialExtensions - Pointer to a RASDIALEXTENSIONS structure that specifies a set of RasDial extended features to enable. Set this parameter to NULL if there is not a need to enable these features.

lpszPhonebook - Pointer to a null-terminated string that specifies the full path and file name 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.

lpRasDialParams - Pointer to a RASDIALPARAMS structure that specifies calling parameters for the RAS connection. Use the RasGetEntryDialParams function to retrieve a copy of this structure for a particular phone-book entry.

dwNotifierType - Specifies the nature of the lpvNotifier parameter. If lpvNotifier is NULL, dwNotifierType is ignored. If lpvNotifier is not NULL, set dwNotifierType to one of the following values.

lpvNotifier - Specifies a window handle or a RasDialFunc, RasDialFunc1, or RasDialFunc2 callback function to receive RasDial event notifications. The dwNotifierType parameter specifies the nature of lpvNotifier. Please refer to its description preceding for further detail.

lphRasConn - Pointer to a variable of type HRASCONN. Set the HRASCONN variable to NULL before calling RasDial. If RasDial succeeds, it stores a handle to the RAS connection into *lphRasConn.

Returns:

If the function succeeds, the return value is ERROR_SUCCESS.

RasEnumConnections

int RasEnumConnections(WinRas.RASCONN[] lprasconn,
                       IntByReference lpcb,
                       IntByReference lpcConnections)

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

Parameters:

lprasconn - Pointer to a buffer that receives, on output, an array of RASCONN structures, one for each RAS connection. On input, an application must set the dwSize member of the first RASCONN structure in the buffer to sizeof(RASCONN) in order to identify the version of the structure being passed.

lpcb - Pointer to a variable that, on input, contains the size, in bytes, of the buffer specified by lprasconn. On output, the function sets this variable to the number of bytes required to enumerate the RAS connections.

lpcConnections - Pointer to a variable that receives the number of RASCONN structures written to the buffer specified by lprasconn.

Returns:

If the function succeeds, the return value is ERROR_SUCCESS.

RasGetConnectionStatistics

int RasGetConnectionStatistics(WinNT.HANDLE hrasconn,
                               Structure.ByReference lpStatistics)

The RasGetConnectionStatistics function retrieves accumulated connection statistics for the specified connection.

Parameters:

hrasconn - Handle to the connection. Use RasDial or RasEnumConnections to obtain this handle.

lpStatistics - Pointer to the RASCONNSTATUS structure that, on output, receives the status information. On input, set the dwSize member of the structure to sizeof(RASCONNSTATUS) in order to identify the version of the structure being passed.

Returns:

If the function succeeds, the return value is ERROR_SUCCESS.

RasGetConnectStatus

int RasGetConnectStatus(WinNT.HANDLE hrasconn,
                        Structure.ByReference lprasconnstatus)

The RasGetConnectionStatistics function retrieves accumulated connection statistics for the specified connection.

Parameters:

hrasconn - Specifies the remote access connection for which to retrieve the status. This handle must have been obtained from RasDial or RasEnumConnections.

lprasconnstatus - Pointer to the RASCONNSTATUS structure that, on output, receives the status information. On input, set the dwSize member of the structure to sizeof(RASCONNSTATUS) in order to identify the version of the structure being passed.

Returns:

If the function succeeds, the return value is ERROR_SUCCESS.

RasGetCredentials

int RasGetCredentials(String lpszPhonebook,
                      String lpszEntry,
                      WinRas.RASCREDENTIALS.ByReference lpCredentials)

The RasGetCredentials function retrieves the user credentials associated with a specified RAS phone-book entry.

Parameters:

lpszPhonebook - Pointer to a null-terminated string that specifies the full path and file name of a phone-book (PBK) 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.

lpszEntry - Pointer to a null-terminated string that specifies the name of a phone-book entry.

lpCredentials - Pointer to the RASCREDENTIALS structure that, on output, receives the user credentials associated with the specified phone-book entry. On input, set the dwSize member of the structure to sizeof(RASCREDENTIALS), and set the dwMask member to indicate the credential information to retrieve. When the function returns, dwMask indicates the members that were successfully retrieved.

Returns:

If the function succeeds, the return value is ERROR_SUCCESS.
