Is there any difference between using Invoke for the parent form or for the target control?

问题

What's the difference between check InvokeRequired and call Invoke method for a control and for the parent form if I want to deal with the control from another thread?

if (theForm.InvokeRequired)
    Invoke(...)

Or

if (myControl.InvokeRequired)
   myControl.Invoke(...)

From MSDN:

The Invoke method searches up the control's parent chain until it finds a control or form that has a window handle if the current control's underlying window handle does not exist yet.

回答1:

These two have the same effect. You can assume the form and the control were created on the same thread.
