vb6 user-defined type not defined error on full compile

Question

I have some vb6 code I have not compiled in a long time. The last compile is in production. Now I get an error "User-defined type is not defined" when I do a full compile. I'm sure there is a reference missing. But there is no code that is hi-lighted. And I cannot seem to find what reference might be lost.

Any clues as to what I can do to find the missing reference would be very helpful.

Thanks!

I've had that happen before it drove me crazy!! But then I found this:

Occurs when compiling with binary compatibility on. The above solution suggests turning off binary compatibility and re-compiling - then missing reference will then be highlighted.

Other steps you can try:

• Rather than turning off BC for everything look for ones that have been recently changed
• search C: drive and dev folder and delete any *.oca files
• also look in the vbp file for any oca references
