Retrieves the return value of the asynchronous operation represented by the IAsyncResult passed.
Public Function EndInvoke ( _ asyncResult As IAsyncResult _ ) As Object
Dim instance As Control Dim asyncResult As IAsyncResult Dim returnValue As Object returnValue = instance.EndInvoke(asyncResult)
public Object EndInvoke( IAsyncResult asyncResult )
public: virtual Object^ EndInvoke( IAsyncResult^ asyncResult ) sealed
public final function EndInvoke( asyncResult : IAsyncResult ) : Object
The asyncResult parameter value is nullNothingnullptra null reference (Nothing in Visual Basic).
The asyncResult object was not created by a preceding call of the BeginInvoke 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.
