128 Extending xDriver

Figure 30. Visual Studio Add New Item Dialog

Select COM Class as the template. This template generates the proper GUIDs

and the required New Sub method for your project. If you copy the sample files

to use as a base for your project, you must change the GUIDs.

Recommendation: Use the name Lookup[Database Type] as the name of the

class, where [Database Type] represents the type of database management

system you are using. You can use this name with the xDriver Profile Editor to

identify the lookup extension component.

Delete the Project Default Class

Use the Solution Explorer to delete the Class1.vb file, the class that was initially

created with the project. Right-click Class1.vb and select Delete, as shown in

Figure 31 on page 129.
