RE: [MS_AccessPros] Proc_Exit

Put all of your cleanup code under Proc_Exit and replace all of the Exit Sub statement with goto Proc_Exit

Thanks John and Crystal.

I appreciate your explanation Crystal. As to why--I realized that I may have a problem since I have a couple of places where I put the rst.close, Set rst = Nothing etc. under Proc_Exit believing that it would be used upon exiting and thus I didn't have to put it with every Exit Sub. So now I know that the rst's and db's in those instances are not being handled properly.

So if I have several Exit Subs before the end of the procedure and a db and rst have been opened previously, what do you recommend--including closing and setting to nothing before each Exit Sub?

Thanks!
