This very detailed and very helpful. We were having a problem with GUI. Even though I am a C++ programmer, I was quickly able to understand and fix the C# problem after reading this article.

Thanks a lot for submitting this valuable stuff. Keep it up.

This is a simple way to raise event or call method from a child thread to update control which does not belongs to that thread.

Are you describing a different way in which to invoke there Kazi?
I’m not exactly sure what it is set out to achieve. Thanks for your comment though.

Try This:

internal static class EventInvoker
{
public static void Invoke(Delegate method,
object[] args)
{
if (method != null)
{
Delegate[] delegates = method.GetInvocationList();

if (delegates.Length > 0)
{
for(int i = 0; i < delegates.Length; i++)
{
Delegate del = delegates[i];

if (del.Target is System.ComponentModel.ISynchronizeInvoke)
{
((System.ComponentModel.ISynchronizeInvoke) del.Target).Invoke (del, args);
}
else
{
del.DynamicInvoke(args);
}
}
}
}
}
}

Then in Client:

public event EventHandler Paused;
private void OnPaused()
{
if (Paused != null)
{
EventInvoker.Invoke(Paused, new object[] {this, EventArgs.Empty});
}
}
