Having made the changes to your VMD file, you are ready to regenerate the stubcode. This section will focus on the effects of the modifications to the table grammar that were made in the previous section.

To regenerate the stubcode:

• Click the Stubcode icon in the toolbar. The Stubcode Generation Wizard appears.
• In the Prefix field, specify a string that will be prepended to certain class names in the generated code. This string may be used to avoid name clashes with existing classes. The default prefix is HL7; you can leave this unchanged.
• In the Language drop-down menu, select C# - Visual Studio .NET 2005 as your programming language.
• In the Project Type drop-down menu, select Stubcode.
• Click Generate to create the stubcode.
• An information box appears, warning you that you are about to overwrite any existing stubcode. Click Yes to continue.
• View the Progress bar to track the progress of the stubcode generation. The stubcode generation is complete when the Progress bar is filled and the message Done! is displayed in the wizard's information panel.
• Click Close to close the window when done.

As you saw in Step 3 - Stubcode Generation, the Stubcode Generation Wizard creates Engine, Message, Table and TableRow classes. This time around, the Wizard has also created a pair of classes for the table group you have just created. These table classes are:

• TblGrpLabResultObservation, which defines the Observation table group for the LabResult class;
• TblGrpLabResultObservationRow, which specifies a row of the Observation table group.

The Message class has also been modified to enable you to access the table group class. Tables in the table group can only be accessed through this table group class.
