It seems that the MS ActiveX DataObjects that you referenced in your application is older than that installed on Win7, IF it was installed correctly. First check your references and make sure that the newest data object (2.8 or higher works fine) is selected. If you can not find it under your references, download the newest MDAC pack and install, then do the reference again.

btw can u let me know which version of MDAC is suitable for Windows 7?

If you download the newest MDAC and reference this in your application, when you compile the app, the version of mdac that you referenced will be added automatically to your .Cab file. When you install the app onto the users machine, Mdac will install as well, ensuring that the user has the correct version, no matter their OS.

MDAC 2.8 and up will be fine on win 7. I am running 2.8 on XP, Vista AND 7 without problems. That means that we have another problem here...

You will receive an error when trying to install MDAC on win 7 because it is already shipped with win 7. There is also a file called WDAC which is replacing MDAC. You might have a problem with this. see the following link, this might help. Please let me know if this solved your problem.

This link shows you how to troubleeshoot the data access objects on win7.

What version of access? because if *.mdb is either 2k or 97 or earlier, you may need MDAC 2.5 as the jet components were seperated out of the MDAC thereafter... Just a thought...

Good Luck
