DLL'S

I have developed an application with Visual C++ 6.0.
when I passed it on to be tested, the following DLL's needed to be replaced:
MFC42.DLL ver 4.21.7160 with ver 6.00.8168.0
MSJET35.DLL ver 3.50.3602.4 with ver 3.51.0623.4


Are these newer versions backward compatable? where did the
newer versions come from?

Thanks for any help.

The DLL's are ususally modified with each version of VC.  You should have a copy of each on your machine, since you installed VC 6.  (And of course the app runs on your machine, right?)  Yes they're supposed to be backward compatible, although microsoft has dropped the ball once or twice in the past.

Ok.  Thanks, that  was quick.

  Then it is ok to overwrite the dlls on the target machine when my application is installing.  These dlls can be distributed I hope...

Does Microsoft have an e-mail address for questions like this?  I do have a subscription to MSDN.

use msdn and do a search on
redistributable files
this should give the microsoft approved way.
