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

Called by GINA to create a modal dialog box from a dialog box template in memory.

Note GINA DLLs are ignored in Windows Vista.

Syntax

PWLX_DIALOG_BOX_INDIRECT PwlxDialogBoxIndirect;

int PwlxDialogBoxIndirect(
  [in] HANDLE hWlx,
  [in] HANDLE hInst,
  [in] LPCDLGTEMPLATE hDialogTemplate,
  [in] HWND hwndOwner,
  [in] DLGPROC dlgprc
)
{...}

Parameters

[in] hWlx

Winlogon handle provided to GINA in the WlxInitialize call.

[in] hInst

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

[in] hDialogTemplate

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.

[in] hwndOwner

Identifies the window that owns the dialog box.

[in] dlgprc

Points to the dialog box procedure. For more information about the dialog box procedure, see DialogProc.

Return value

If the WlxDialogBoxIndirect function succeeds, the return value is 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 code	Description
WLX_DLG_INPUT_TIMEOUT	Input timed out.
WLX_DLG_SAS	A secure attention sequence (SAS) event occurred.
WLX_DLG_SCREEN_SAVER_TIMEOUT	The screen saver timed out.
WLX_DLG_USER_LOGOFF	The user logged off.

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

Remarks

WlxDialogBoxIndirect duplicates the Windows DialogBoxIndirect macro, and also allows Winlogon to terminate the dialog box. For more information, see DialogBoxIndirect.
