crystal Report ActiveX Designer

i am trying to create connection with access in crystal report, then I am getting following error

Logon Failed
Details: DAO Error code 0xbb9
Source: DAO. TableDefs
Description: Invalid Argument


is there any body who can guide me in resolving this problem

note: Earlier the same process of connecting to database was working quite well.

No idea, you have not shown us any of your code. Odd that it is using DAO as that is very very outdated. Pretty much hasn't been used since the 90s.

I assume you are using VB6 or 5 or Access VBA rather than VB.Net.
