>>It's the class of the current object, but the code you see in the trace window is not necessarily in that class. It may come from the parent class, grandparent class etc. VFP knows where it comes from, because it unmistakenly takes you there when you choose Debug/Fix, or shows it in the PEM window while editing a class. I may like to know that right away while debugging.

Just tried it (keeping This.class in watch window) in VFP7 - and I had a break on dodefault(). Before executing that line, it showed the class of the object, fine. While executing the parent code, it didn't change the class - which is what I expected, because This is still the same object, and it can't change the class on the fly. I think this is OK, but still I'd need the information on where does this code come from, without having to debug/fix to get it. It could be an option to echo the exact "class .... of (vcx) method (object.method)" in the DebugOut window. A FoxWish, eh?
