RasDialDlg info  Overview  Group

The RasDialDlg function tries to establish a RAS connection using a specified phone-book entry and the credentials of the logged-on user. The function displays a stream of dialog boxes that indicate the state of the connection operation.

BOOL RasDialDlg(

Parameters

lpszPhonebook

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.

lpszEntry

Pointer to a null-terminated string that contains the name of the phone-book entry to dial.

lpszPhoneNumber

Pointer to a null-terminated string that contains a phone number that overrides the numbers stored in the phone-book entry. If this parameter is NULL, RasDialDlg uses the numbers in the phone-book entry.

lpInfo

Pointer to a RASDIALDLG structure that contains additional input and output parameters. On input, the dwSize member of this structure must specify sizeof(RASDIALDLG). If an error occurs, the dwError member returns an error code; otherwise, it returns zero.

Return Values

If the function establishes a RAS connection, the return value is a nonzero value.

If an error occurs, or if the user selects the Cancel button during the dialing operation, the return value is zero. If an error occurs, the dwError member of the RASDIALDLG structure returns a nonzero system or RAS error code.

Remarks

The RasDialDlg function displays a stream of dialog boxes that are similar to the dialog boxes that main Dial-Up Networking dialog box displays when the user selects the Dial button. The RasDialDlg function is useful for applications in which you want to display a standard user interface for a connection operation without presenting the main phone-book dialog box. For example, the RAS AutoDial service uses this function to establish a connection using the phone-book entry associated with a remote address.

The RasDialDlg function displays dialog boxes during the connection operation to provide feedback to the user about the progress of the operation. For example, the dialog boxes might indicate when the operation is dialing, when it is authenticating the user’s credentials on the remote server, and so on. The dialog boxes also provide a Cancel button for the user to terminate the operation.

RasDialDlg returns when the connection is established, or when the user cancels the operation.
