问题 I'm building an install using VS 2003. The install has an Excel workbook and two Access databases. I need to force the Access files to load regardless of the create/mod date of the existing databases on the user's computer.

So, for example: SEQ GROUP1 GROUP2 GROUP3 VALUE ---- ------- ------- ------- ------ 1 A A A 123 2 A A A 456 3 A B C foo 5 X Y Z bar 4 A B D baz I would like this data grouped in this hierarchy, but ordered by SEQ . So, the above data would produce a report like: A A A 123 456 B
