RasGetCredentials
[New - Windows NT]
The RasGetCredentials function retrieves the user credentials associated with a specified RAS
phone-book entry.
DWORD RasGetCredentials(
LPTSTR lpszPhonebook,
| // pointer to the full path and filename of a phone-book file
| LPTSTR lpszEntry,
| // pointer to the name of a phone-book entry
| LPRASCREDENTIALS lpCredentials
| // pointer to structure that receives credentials
| );
|
|
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 a phone-book
entry.
lpCredentials
Pointer to a RASCREDENTIALS structure that receives the user credentials associated with the specified
phone-book entry. Before calling RasGetCredentials, set the dwSize member of the structure to sizeof(RASCREDENTIALS), and set the dwMask member to indicate the credential information to retrieve. When the function
returns, dwMask indicates the members that were successfully retrieved.
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.
Value
| Meaning
| ERROR_CANNOT_OPEN_PHONEBOOK
| The specified phone book cannot be found.
| ERROR_CANNOT_FIND_PHONEBOOK_ENTRY
| The specified entry does not exist in the phone book.
| ERROR_INVALID_PARAMETER
| The lpCredentials parameter was NULL.
| ERROR_INVALID_SIZE
| The dwSize member of the RASCREDENTIALS structure is an unrecognized value.
|
Remarks
The RasGetCredentials function retrieves the credentials of the last user to successfully connect
using the specified phone-book entry, or the credentials subsequently specified
in a call to the RasSetCredentials function for the phone-book entry.
The RasGetCredentials function retrieves the user credentials that are stored securely for the
specified phone-book entry. This function is the preferred way of securely
retrieving the credentials associated with a RAS phone book entry. RasGetCredentials supersedes the RasGetEntryDialParams function, which may not be supported in future releases of Windows NT.

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 » |
