I added file #10023 to the download section so you could see what I am talking about.

>possible at design time to add new properties and methods to an object already on a form (don't ask me how).

I was really hoping that someone knew how the internals work for this mechanism. I guess only the Fox team at MSFT knows.

Actually, it is possible at runtime to add objects to containers. I don't think it is possible to add PEM's to the object on the form. I really haven't done it myself so I'm going to look into it.

One last note: drag a base class onto a form, like a commandbutton. The parentclass in the property sheet is "None" and the class is "CommandButton". So it is like an instance of the commandbutton class that you can add code to and get the inherited behavior by running DODEFAULT().

Thanks.

>The problem I had has been fixed in VFP7!. But they haven't "fixed" your problem. It's a fine line here between an object class and an object instance as others have said. When you drop the object onto the form you aren't really subclassing; even though I believe it is possible at design time to add new properties and methods to an object already on a form (don't ask me how). The form isn't really a subclass either, but it's "real" close. Wave-particle :-)

>>>No they don't :-), but I agree with Dave now. See my other post. If you create a command button class, and in the click method of the class access a protected property or method of the same class at the same level then drop that button onto a form, the click method fails!
