We have developed a financial quotation system in VB4. It runs on stand-alone PCs, uses Access databases, performs financial calculations etc.
We have been asked to investigate the development of the system as a Browser enabled product, with it running on a Web server, the user interface will be a Browser.
It has been suggested that the server could be an NT 4.0 Server running IIS3.0 and the client would be Windows 95/98 running Microsoft IE4.0
We are thinking of developing this using Microsoft Active-X technology, but we are on a steep learning curve.
So far we've got some vague ideas about this - We will change our VB forms into Active-X documents (written in VB 5) on the Web server there will be a VB program performing tasks centrally. We understand there is a Wizard to convert VB forms to Active - X. Is it any good? How far will it get us? (I assume I'll have to upgrade my forms to VB 5 to use it).
I am curious about things like database access - will the bits that do this have to be on the server or will we be able to use database commands in the Active-X documents to get data from server.
We have been asked about VB script, what is it? and will we be needing to use it in the development. Are there any good Web sites to read about this stuff.
I'd be very greatful for any suggestions/comments/answers - what we are trying to get together at the moment is an outline strategy - like do we need a complete re-write/re-design or can we convert?
