WlxDialogBoxIndirectParam function

[The WlxDialogBoxIndirectParam function is no longer available for use as of Windows Server 2008 and Windows Vista.]

Called by GINA to initialize dialog box controls and then create a modal dialog box from a dialog box template in memory.

Note   GINA DLLs are ignored in Windows Vista.

Syntax


int WlxDialogBoxIndirectParam(
  _In_  HANDLE hWlx,
  _In_  HANDLE hInst,
  _In_  LPCDLGTEMPLATE hDialogTemplate,
  _In_  HWND hwndOwner,
  _In_  DLGPROC dlgprc,
  _In_  LPARAM dwInitParam
);

Parameters

hWlx [in]

Specifies the Winlogon handle passed to GINA in the WlxInitialize call.

hInst [in]

Specifies the instance of the module that creates the dialog box.

hDialogTemplate [in]

Specifies the address of a global memory object that contains a dialog box template used to create the dialog box. The template is in the form of a DLGTEMPLATE structure followed by one or more DLGITEMTEMPLATE structures. For a full description of these structures, see the Platform SDK.

hwndOwner [in]

Specifies the window that owns the dialog box.

dlgprc [in]

Points to the dialog box procedure. For more information about the dialog box procedure, see the description of the DialogProc callback function in the Platform SDK.

dwInitParam [in]

Specifies the value used to initialize the dialog box control. This value is passed to the dialog box in the lParam parameter of the WM_INITDIALOG message.

Return value

If the function succeeds, the function returns the nResult parameter given in the call to the EndDialog function used to terminate the dialog box. The following table lists some possible success return values.

Return codeDescription
WLX_DLG_INPUT_TIMEOUT

WLX_DLG_SAS

A secure attention sequence (SAS) event occurred.

WLX_DLG_SCREEN_SAVER_TIMEOUT

WLX_DLG_USER_LOGOFF

If the function fails, the return value is –1.

Remarks

WlxDialogBoxIndirectParam duplicates the Windows DialogBoxIndirectParam function and also allows Winlogon to terminate the dialog box. For more information, see DialogBoxIndirectParam.
