Is there an API call for Crystal Reports 8.5 that will generate a TTX schema file from a VB6 ADODB.Recordset at runtime, much in the same way you can generate an XSD from a DataSet in .NET?

This may be because they want people who can convert code from classic to .NET, but I'm not really sure. Would classic VB and ASP be helpful...
I have several VB6 ActiveX server exe files which need to be registered on install before they can be used. I have tried using Heat to extract the information but it only generates a file element.

I'd love to dive into kernel hooking - but my problem is that I don't like C/C++. But I've over 10 years experience in VB6 programming and would call my self as an expert in this language.

Hi all, I'm writing an application that is able to be connected to multiple types of database (eg: SQL Server, Oracle, MySQL, etc). It's an international-targeted application, so I ideally want to be able to do this without needing to rely on string literals if possible.
