WlxDialogBox function
[The WlxDialogBox function is no longer available for use as of Windows Server 2008 and Windows Vista.]
Called by the GINA to create a modal dialog box from a dialog box template.
Syntax
int WlxDialogBox(
_In_ HANDLE hWlx,
_In_ HANDLE hInst,
_In_ LPWSTR lpszTemplate,
_In_ HWND hwndOwner,
_In_ DLGPROC dlgprc
);
Parameters
- hWlx [in]
-
Specifies the Winlogon handle passed to GINA in the WlxInitialize call.
- hInst [in]
-
Specifies an instance of the module whose executable file contains the dialog box template.
- lpszTemplate [in]
-
Specifies the dialog box template. This parameter is either the address of a null-terminated character string that specifies the name of the dialog box template, or an integer value that specifies the resource identifier of the dialog box template. If the parameter specifies a resource identifier, its high-order word must be zero and its low-order word must contain the identifier. You can use the MAKEINTRESOURCE macro to create this value.
- 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 DialogProc callback function.
Return value
If the WlxDialogBox 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 |
|---|---|
|
Input timed out. |
|
A secure attention sequence (SAS) event occurred. |
|
The screen saver timed out. |
|
The user logged off. |
If the function fails, the return value is –1.
Remarks
GINA must use the Winlogon WlxDialogBox function, not the Windows DialogBox macro. WlxDialogBox duplicates the Windows DialogBox macro, and also allows Winlogon to terminate the dialog box. For more information, see DialogBox.
