Conclusion
Using Visual Basic to create Web-aware custom controls brings VB programming in line with Java. While ActiveX custom controls do not enjoy the "run anywhere" utility of Java, the fact that 90% of all desktop computers use the Windows operating system and that Internet Explorer is a free product makes this technology genuinely viable. The ability to make Web-aware custom components in Visual Basic is a good skill to have. Both the Internet and Visual Basic play a large role in Microsoft's plans, and Microsoft plans to do a lot with the Internet. It's no secret that Microsoft is "betting the farm" on the next generation of Internet use. If you have any anxiety about the viability of using VB to program for the Web, don't! Microsoft, the Internet, and Visual Basic are not going away in the foreseeable and distant future. Make your Visual Basic custom controls Web-aware. It's a good bet.
