RasGetProjectionInfo
The RasGetProjectionInfo function obtains information about a remote access projection operation for a
specified remote access component protocol.
DWORD RasGetProjectionInfo(
HRASCONN hrasconn,
| // handle that specifies remote access connection of interest
| RASPROJECTION rasprojection,
| // specifies type of projection information to obtain
| LPVOID lpprojection,
| // points to buffer that receives projection information
| LPDWORD lpcb
| // points to variable that specifies buffer size
| );
|
|
Parameters
hrasconn
Handle to the remote access connection of interest. An application obtains a
RAS connection handle from the RasDial or RasEnumConnections function.
rasprojection
A RASPROJECTION enumerated type value that specifies the protocol of interest.
lpprojection
Points to a buffer that will receive the information specified by the rasprojection parameter. The information will be in a structure appropriate to the rasprojection value:
lpcb
Points to a variable that, on entry, specifies the size in bytes of the buffer
pointed to by lpprojection. On exit, this variable contains the size of buffer needed to contain the
specified projection information.
Return Values
If the function succeeds, the return value is zero.
If the function fails, the return value is an error code. The function may
return a nonzero RAS error code, or one of the following error codes:
Value
| Meaning
| ERROR_BUFFER_TOO_SMALL
| The buffer pointed to by lpprojection is not large enough to contain the requested information.
| ERROR_INVALID_HANDLE
| The hrasconn parameter is not a valid handle.
| ERROR_INVALID_PARAMETER
| One of the parameters is invalid.
| ERROR_INVALID_SIZE
| The dwSize member of the structure pointed to by lpprojection specifies an invalid size.
| ERROR_PROTOCOL_NOT_CONFIGURED
| The control protocol for which information was requested neither succeeded nor
failed, because the connection's phone-book entry did not require that an
attempt to negotiate the protocol be made. This is a RAS error code.
|
Remarks
Remote access projection is the process whereby a remote access server and a
remote client negotiate network protocol-specific information. A remote access
server uses this network protocol-specific information to represent a remote
client on the network.
Windows NT: Remote access projection information is not available until the operating
system has executed the RasDial RASCS_Projected state on the remote access connection. If RasGetProjectionInfo is called prior to the RASCS_Projected state, it returns
ERROR_PROJECTION_NOT_COMPLETE.
Windows 95: Windows 95 Dial-Up Networking does not support the RASCS_Projected state. The
projection phase may be done during the RASCS_Authenticate state. If the
authentication is successful, the connection operation proceeds to the
RASCS_Authenticated state, and projection information is available for successfully
configured protocols. If RasGetProjectionInfo is called prior to the RASCS_Authenticated state, it returns
ERROR_PROTOCOL_NOT_CONFIGURED.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
