If you have been using the Component Enabler Visual Basic 6 client generator, you have the choice of staying with the Java Style interface, with only some minor changes, or using the new CEWindowsAPI interface.
The CEWindowsAPI interface requires changing more lines of code, but the look and feel of the resulting code is more like standard VB code.
In either case, all changes are to infrastructure files. The generated files (static or dynamic forms) do not directly make calls against the Component Enabler runtime environment, and hence do not require any changes.
Converting to the CEWindowAPI Interface.
There are two ways of changing to using the new interface. Oneallows early binding and IntelliSense works in Visual Studio, and the other uses late binding, with no IntelliSense.
