This method retrieves a handle to a manual-reset event that will be signaled as long as there are event notifications to deliver.

Syntax 

HRESULT GetEventHandle(
  OAEVENT* 
hEvent
);

Parameters

hEvent

[out] Handle for the event.

Return Value

Returns an HRESULTvalue.

Remarks

You can monitor events (including the retrieved event) and messages on a single thread; to do this, declare a HANDLE variable, cast it to an OAEVENT pointer, then pass it to GetEventHandle. You must cast the pointer to an OAEVENT pointer because HANDLE is not a valid OLE Automation type. The following code fragment demonstrates how to cast and use the HANDLE.

Copy Code 
HANDLE hEvent;
GetEventHandle( (OAEVENT*) &hEvent );

You can pass the retrieved event handle to the Win32 WaitForMultipleObjectsor MsgWaitForMultipleObjectsfunctions to wait for event notifications at the same time as other messages and events on a single thread. The implementation of GetEventsets and resets the handle within the application, so applications should not reset the handle themselves.
