RasSetEntryDialParams info  Overview  Group

The RasSetEntryDialParams function changes the connection information saved by the last successful call to the RasDial or RasSetEntryDialParams function for a specified phonebook entry.

DWORD RasSetEntryDialParams(

    LPTSTR lpszPhonebook,

// pointer to the full path and filename of the phonebook file

    LPRASDIALPARAMS lprasdialparams,

// pointer to a structure with the new connection parameters

    BOOL fRemovePassword

// indicates whether to remove password from entry’s parameters



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.

Windows 95: Dial-up networking stores phonebook entries in the registry rather than in a phonebook file.

Points to a RASDIALPARAMS structure containing the connection parameters to be associated with the phonebook entry. RasSetEntryDialParams uses the structure’s members as follows:




Must specify the sizeof(RASDIALPARAMS) to identify the version of the structure.


A null-terminated string that identifies the phonebook entry to set parameters for.


Not used. Set to NULL.


A null-terminated string containing the callback phone number. If szCallbackNumber is an empty string ( ““ ), the callback number is not changed.


A null-terminated string containing the logon name of the user associated with this entry. If szUserName is an empty string, the user name is not changed.


A null-terminated string containing the password for the user specified by szUserName. If szUserName is an empty string, the password is not changed. If szPassword is an empty string and fRemovePassword is FALSE, the password is set to the empty string. If fRemovePassword is TRUE, the password stored in this phonebook entry for the user specified by szUserName is removed regardless of the contents of the szPassword string.


A null-terminated string containing the name of the domain to log on to. If szDomain is an empty string, the domain name is not changed.

Indicates whether to remove the phonebook entry’s stored password for the user specified by lprasdialparams->szUserName. If fRemovePassword is TRUE, the password is removed.

Return Values

If the function succeeds, the return value is zero.

If the function fails, the return value can be one of the following error codes:




The address or buffer specified by lprasdialparams is invalid.


The phonebook is corrupted or missing components.


The phonebook entry does not exist.
