The RASDIALPARAMS structure contains parameters used by RasDial
to establish a remote access connection.
typedef struct _RASDIALPARAMS {
DWORD dwSize;

TCHAR szCallbackNumber[RAS_MaxCallbackNumber + 1];

TCHAR szPassword[PWLEN + 1];
TCHAR szDomain[DNLEN + 1] ;

} RASDIALPARAMS;
Members
-
dwSize
-
Specifies the structure size, in bytes.
-
szEntryName
-
Specifies a string containing the phone-book entry to use to establish the
connection. An empty string (““) specifies a simple modem connection on the
first available modem port, in which case a nonempty szPhoneNumber must
be provided.
-
szPhoneNumber
-
Specifies a string containing an overriding phone number. An empty string (““)
indicates that the phone-book entry’s phone number should be used. If szEntryName
is ““, szPhoneNumber cannot be ““.
-
szCallbackNumber
-
Specifies a string containing a callback phone number. An empty string (““)
indicates that callback should not be used. This string is ignored unless the
user has “Set By Caller” callback permission on the RAS server. An asterisk
indicates that the number stored in the phone book should be used for
callback.
-
szUserName
-
Specifies a string containing the user’s user name. This string is used to
authenticate the user’s access to the remote access server.
-
szPassword
-
Specifies a string containing the user’s password. This string is used to
authenticate the user’s access to the remote access server.
Windows NT: You can use szPassword to send a new password to the
remote server when you restart a RasDial connection from a
RASCS_PasswordExpired paused state. When changing a password on an entry that
calls Microsoft Networks, you should limit the new password to 14 characters
in length to avoid down-level compatibility problems.
-
szDomain
-
Specifies a string containing the domain on which authentication is to occur.
An empty string (““) specifies the domain in which the remote access server is
a member. An asterisk specifies the domain stored in the phone book for the
entry.
-
dwSubEntry
-
Specifies the index of the initial subentry to dial. If the phone-book entry
has no subentries or the dial mode of the phone-book entry is RASEDM_DialAll, dwSubEntry
is ignored. If the dial mode is RASEDM_DialAsNeeded, RAS dials the specified
subentry. If dwSubEntry is not a valid subentry index, RAS dials the
first subentry. The RASENTRY structure
returned by RasGetEntryProperties
indicates the dial mode and number of subentries for the phone-book entry.
-
dwCallbackId
-
Specifies an application-defined value that RAS passes to your RasDialFunc2
callback function.
Remarks
The szUserName and szPassword strings are used to authenticate
the user’s access to the remote access server.
-
Windows NT:
-
RAS does not actually log the user onto the network. The user does this in the
usual manner, for example, by logging on with cached credentials prior to
making the connection or by using CTRL+ALT+DEL, after the RAS connection is
established.
If both the szUserName and szPassword members are empty strings
(""), RAS uses the user name and password of the current logon
context for authentication. For a user mode application, RAS uses the
credentials of the currently logged-on interactive user. For a Win32 service
process, RAS uses the credentials associated with the service.
-
Windows 95:
-
RAS uses the szUserName and szPassword strings to log the user
onto the network. Windows 95 cannot get the password of the currently
logged-on user, so if both the szUserName and the szPassword
members are empty strings (““), RAS leaves the user name and password empty
during authentication.
