Re: Access violation in CreateForm

Tom/Daniel

Thanks for these replies. 

I thought that the TEMP environment setting only affected Win 2K, not 
NT or XP. We actually have had the problem with two different 
versions of our app, one built with the free version of QR 3.0 and 
the other with QR Professional 3.0.8 which has the fix for TEMP (we 
have a number of users on Win 2K). Yes, I did try the QR Knowledge 
Base but could not find anything.

I will look at creating the forms on demand. You are right that it is 
a good technique for reports although it does not explain why PCs 
suddenly develop this problem and, as you say, it may only delay the 
problem.

Best wishes
