Public Function EndInvoke (asyncResult As IAsyncResult) As Object
The Object generated by the asynchronous operation.
asyncResult parameter value is
asyncResult object was not created by a preceding call of the BeginInvoke(Delegate) method from the same control.
If the asynchronous operation has not been completed, this function will block until the result is available.
In addition to the InvokeRequired property, there are four methods on a control that are thread safe: Invoke, BeginInvoke, EndInvoke, and CreateGraphics if the handle for the control has already been created. Calling CreateGraphics before the control's handle has been created on a background thread can cause illegal cross thread calls. For all other method calls, you should use one of the invoke methods to marshal the call to the control's thread.
