RasSetAutodialParam function

The RasSetAutodialParam function sets the value of an AutoDial parameter.

Syntax


DWORD RasSetAutodialParam(
  _In_  DWORD  dwKey,
  _Out_ LPVOID lpvValue,
  _In_  DWORD  dwcbValue
);

Parameters

dwKey [in]

Specifies the AutoDial parameter to set. This parameter can be one of the following values.

ValueMeaning
RASADP_DisableConnectionQuery

The lpvValue parameter points to 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 one, 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 points to a DWORD value. If this value is one, 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 points to 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 points to a DWORD value that indicates a time-out value, in seconds. When an AutoDial connection attempt fails, the AutoDial system service disables subsequent attempts to reach the same address for the time-out period. This prevents AutoDial from displaying multiple connection dialog boxes for the same logical request by an application. The default value is five.

RASADP_ConnectionQueryTimeout

The lpvValue parameter points to a DWORD value that indicates a time-out value, in seconds. Before attempting an AutoDial connection, the system will display a dialog asking the user to confirm that the system should dial. The dialog has a countdown timer that terminates the dialog with a "Do not dial" selection if the user takes no action. The DWORD value pointed to by lpvValue specifies the initial time on this countdown timer.

 

lpvValue [out]

Pointer to a buffer that contains the new value for the specified parameter.

dwcbValue [in]

Specifies the size, in bytes, of the value in the lpvValue buffer.

Return value

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value is one of the following error codes or a value from Routing and Remote Access Error Codes or Winerror.h.

ValueMeaning
ERROR_INVALID_PARAMETER

The dwKey or lpvValue parameter is invalid.

ERROR_INVALID_SIZE

The size specified by the dwcbValue is invalid.
