Obviously something invalid was left there by mistake, but since VFP apparently uses the class version defined LAST within the vcx ( strange but true ! ), and that class worked well, I didn't notice the problem. Recently, when I used Fernando's excellent foxbin2prg in a round trip (bin2text and then text2bin) it apparently selected the class version defined FIRST in the VCX as the valid class. That class had an error and it showed up. Just deleted the incorrect class.

Hi Lutz,

I did copy Fernando on that last message, but I will bring it to his attention again.

I thought of it as *my* problem rather than in Fernando's, but I guess in a way it can be dealt with by foxbin2prg.

Thanks for the suggestion,

Alex
