Hi Kevin,

Did you know about object references in VFP ?

Local myText as TextBox

myText = thisform.text1
myText.Value = "Hello"

well, you have to see Delegates as Method references. When you invoke a delegate, it means that you invoke one or more method(s).

I am like you, I am a VFP Developer trying to understand through the lens of VFP.

If you don't mind, I suggest you to read C# School eBook at http://www.programmersheaven.com/download/50118/download.aspx This free ebook help me a lot how to see C# from the beginners perspective.

Just my 0.2 cents :-)
