RASDIALPARAMS
The RASDIALPARAMS
structure contains parameters used by RasDial1ZUV.VA to establish a remote access connection.
typedef struct _RASDIALPARAMS {
DWORD dwSize;
TCHAR szEntryName[RAS_MaxEntryName + 1];
TCHAR szPhoneNumber[RAS_MaxPhoneNumber + 1];
TCHAR szCallbackNumber[RAS_MaxCallbackNumber + 1];
TCHAR szUserName[UNLEN + 1];
TCHAR szPassword[PWLEN + 1];
TCHAR szDomain[DNLEN + 1] ;
#if (WINVER >= 0x401)
DWORD dwSubEntry;

} RASDIALPARAMS;
Members
dwSize
Specifies the
structure size, in bytes.
szEntryName
Specifies a
string containing the phonebook 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 phonebook 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 phonebook 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 phonebook
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
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.
