>Is there a limit on how many methods and or properties a custom class can have?

I know of no such limit - the limit is probably more of a practical nature: due to the way VFP manages variables, it will probably get slower if you have LOTS of properties.

Also, a class with thousands of properties MIGHT be an indication of a bad design.

Of course, you could just test it. The following code, which I put into a CommandButton, went all the way to 20,000 - I was too impatient to wait any longer. But after a few thousand properties, execution slowdown was quite noticeable.

i = 1
do while .T.
	if i % 100 = 0
		wait window nowait trans(i)
	endif
	PropertyName = "Prop" + trans(i)
	This.AddProperty(PropertyName)
	i = i + 1
enddo
