Examples

The following example shows how to use a DispatcherFrame to achieve similar results as the Windows Forms DoEvents method.

public void DoEvents()
{
    DispatcherFrame frame = new DispatcherFrame();
    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background,
        new DispatcherOperationCallback(ExitFrame), frame);
    Dispatcher.PushFrame(frame);
}

public object ExitFrame(object f)
{
    ((DispatcherFrame)f).Continue = false;
   
    return null;
}

<SecurityPermissionAttribute(SecurityAction.Demand, Flags := SecurityPermissionFlag.UnmanagedCode)>
Public Sub DoEvents()
    Dim frame As New DispatcherFrame()
    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background, New DispatcherOperationCallback(AddressOf ExitFrame), frame)
    Dispatcher.PushFrame(frame)
End Sub

Public Function ExitFrame(ByVal f As Object) As Object
    CType(f, DispatcherFrame).Continue = False

    Return Nothing
End Function

Remarks

Continue is queried at the top of each dispatcher loop.

At application shutdown, all frames are request to exit.
