Summary

Migration from Visual Basic 6.0 to Visual Basic .NET will not be much different than the migration for other technologies. Microsoft has gone out of its way to make sure that your old code will continue to work from .NET. This means that you do not need to be in a rush to migrate. Calls going from .NET to COM will cost more time than sticking with straight .NET or COM, but this does give you time to make the right decisions. If the application calls across this boundary one to ten times per second, you probably have no worries.

Use the information in this chapter to identify ways to expose existing code as a Web Service. Sometimes, you will be able to run the SOAP Toolkit's WSDL Generator and be done. Other times, you will write a front end using either .NET or the STK to access the code. Regardless of what you do, take some time to analyze what you need to accomplish and focus on that. You certainly have some code that will be valuable as a Web Service somewhere in your business.
