RasGetAutodialParam
[New - Windows NT]
The RasGetAutodialParam function retrieves the value of an AutoDial parameter.
DWORD RasGetAutodialParam(
DWORD dwKey,
| // indicates the parameter to retrieve
| LPVOID lpvValue,
| // pointer to a buffer that receives the value
| LPDWORD lpdwcbValue
| // size, in bytes, of the buffer
| );
|
|
Parameters
dwKey
Indicates the AutoDial parameter to retrieve. This parameter can be one of the
following values.
Value
| Meaning
| RASADP_DisableConnectionQuery
| The lpvValue parameter returns a DWORD value. If this value is zero (the default), AutoDial displays a dialog box to
query the user before creating a connection. If this value is 1, and the
AutoDial database has the phone-book entry to dial, AutoDial creates a connection
without displaying the dialog box.
| RASADP_LoginSessionDisable
| The lpvValue parameter returns a DWORD value. If this value is 1, the system disables all AutoDial connections for
the current logon session. If this value is zero (the default), AutoDial
connections are enabled. The AutoDial system service changes this value to zero when a
new user logs on to the workstation.
| RASADP_SavedAddressesLimit
| The lpvValue parameter returns a DWORD value that indicates the maximum number of addresses that AutoDial stores in
the registry. AutoDial first stores addresses that it used to create an
AutoDial connection; then it stores addresses that it learned after a RAS connection
was created. Addresses written using the RasSetAutodialAddress function are always saved, and are not included in calculating the limit. The
default value is 100.
| RASADP_FailedConnectionTimeout
| The lpvValue parameter returns a DWORD value that indicates a timeout value, in seconds. When an AutoDial connection
attempt fails, the AutoDial system service disables subsequent attempts to
reach the same address for the timeout period. This prevents AutoDial from
displaying multiple connection dialog boxes for the same logical request by an
application. The default value is 5.
|
lpvValue
Pointer to a buffer that receives the value for the specified parameter.
lpdwcbValue
Pointer to a DWORD value. On input, set this value to indicate the size, in bytes, of the lpvValue buffer. On output, this value indicates the actual size of the value written
to the buffer.
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_INVALID_PARAMETER
| The dwKey or lpvValue parameter is invalid.
| ERROR_INVALID_SIZE
| The size specified by the lpdwcbValue is too small.

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 » |
