>So... I tried putting the error handling code into the ERROR procedure of the class. Once again, it works in vanilla VFP, but not within the CodeMine framework.

Could you explain where Codemine actually fits in to this scenario? You developed a specialised visual class - have you now redeveloped the same class in Codemine (even though you dont own it) or are you trying to call your class from an existing Codemine application where you have access to its source?

>Can someone tell me how to bypass the CodeMine error handler for my comm check?

Codemine's error handling routine just works on a "chain of responsibility" basis. If the localised class cannot handle any error it encounters, it just passes it up to the next level. If you could elaborate a little on how it hangs together, maybe we can figure out where to "break the chain" <s>.

Its pretty late here now so I am now going to keep my Wife company <s>. If you post any more info about this problem, I will gladly take a look at it in the morning.
