Retrieves a window handle to a messenger window. Not scriptable.

Syntax

HRESULT HWND(
   [out,
   retval] long* phWnd
);

Parameters

phWnd

Pointer to a LONG that receives a HWND handle to this messenger window.

Return Value

Returns one of the following values. For managed code applications, these return values are received in the form of a COMException.

S_OK

Success.

RPC_X_NULL_REF_POINTER

phWnd is a null pointer.

E_FAIL

Cannot get a window handle.

E_NOTIMPL

The property cannot be accessed through scripting.

Remarks

Unlike the Messenger application, there can be more than one conversation window and therefore more than one HWND. Each individual conversation window handle (HWND) is retrieved by querying the specified conversation window HWND property.

If called on the IMessengerWindow interface of the application's messenger window, it returns a HWND for the messenger window instantiated by the parent application.

Example

The code example uses a previously instantiated Messenger interface object called communicator to retrieve the window handle from the IMessenger::Window property. The window handle is displayed in a console window if it is retrieved without error. In the event of an error, the communicator object raises a COM exception that is caught and displayed in the console window.

Copy Code 
if (communicator != null)
{
   IMessengerWindow messengerWindow;
   try
   {
	 messengerWindow = (IMessengerWindow)communicator.Window;
	 Console.WriteLine("Messenger Window: " + messengerWindow.HWND.ToString());
   }
   catch (COMException GWCE)
   {
	 Console.WriteLine(GWCE.ErrorCode.ToString());
   }
}
