WinDlgBox

This function loads and processes a modal dialog window and returns the result value established by the WinDismissDlg call.

Syntax

WinDlgBox(hwndParent, hwndOwner,pfnDlgProc, hmod, idDlg, pCreateParams);

Parameters

hwndParent (HWND) - input

Parent-window handle of the created dialog window.

HWND\_DESKTOP: The desktop window.

HWND\_OBJECT: Object window.

Other: Specified window.

hwndOwner (HWND) - input

Requested owner-window handle of the created dialog window.

The actual owner window is calculated using the algorithm specified in the description of the WinLoadDlg function.

pfnDlgProc (PFNWP) - input

Dialog procedure for the created dialog window.

hmod (HMODULE) - input

Resource identity containing the dialog template.

NULLHANDLE: Use the application's .EXE file.

Other: Module handle returned from the DosLoadModule or DosQueryModuleHandle call.

idDlg (ULONG) - input

Dialog-template identity within the resource file.

It is also used as the identity of the created dialog window. It must be greater than or equal to 0 and less than or equal to 0xFFFF.

pCreateParams (PVOID) - input

Pointer to application-defined data area.

This is passed to the dialog procedure in the WM\_INITDLG message.

This parameter MUST be a pointer rather than a long.

Returns

ulResult (ULONG) - returns

Reply value.

Value established by the WinDismissDlg call or DID\_ERROR if an error occurs.

Remarks

The use of parameters for this function is the same as those of the WinLoadDlg function.

This function should not be used while pointing device capture is set (see WinSetCapture).

This function does not return until WinDismissDlg is called.

This function is equivalent to:

ULONG    ulResult;      /* Reply value. */

ulResult = WinDlgBox(hwndParent, hwndOwner,
                     pfnDlgProc, hmod, idDlg, pCreateParams);
