Reviving ancient Visual Basic project: possible?
I've been asked to evaluate the difficulty of extracting data from an old VB project and have a couple of questions for any VB experts out there (That's you lot :)
It's a custom built application holding the archives of a now defunct magazine - written in 1998 in VB 4.0. and currently sits on 2 CDs. There is a Setup.exe plus a bunch of .DLLs and other hidden files in the root of the CD. These files all appear to be common to both disks. There is also a Data directory on each CD with a common folder structure but different contents.
The first issue is running it - the VB stub Setup.exe on the CDs will only run on 32 bit windows. Is it likely to be possible to replace that and other VB files with equivalents from a newer version of VB to let it run on 64 bit Windows?
My other question is about the structure of VB projects - are they compiled or interpreted? By this I really want to know whether its likely that a modern version of VB could be used to open and edit the project? Or would that require some extra source code files that would not have been included on the CDs when they were originally created? Ideally they would like to combine the data from the 2 CDs and install on a hard disk rather than requiring the physical CD to be present in the drive. This would require rebuilding .IDX index files and the like.
Any insights or advice would be much appreciated.
