>To be honest, I've been a bit distressed about seeing all the posts about this error. Personally, I'd only encountered it twice (before this evening). Once was with an SDI application where the computer didn't have the DCOM95 program loaded. The other was when I did something very stupid with an ActiveX control. Well, tonight I've encountered it several times, and I think I *may* have figured something out.

I just got the C5 again in a different situation and I didn't find anything along those lines anywhere so I thought it would be good to mention it:

I have a SQL Select statement with 238 fields that always gives me the C5.

If I cut down to 237 fields, I don't get the error but I get wrong info in the 2 last fields (!). I had to cut it down a little more and do an Alter Table to add the missing fields and fill them manually...(that's the best workaround I found)...
