Once you complete your code in Visual C++ or Visual Basic you need to update the model to reflect any changes. This can be accomplished by using the Model Update tool. You can also use this tool to create an initial model for existing code.
TO UPDATE (CREATE) A MODEL FROM CODE USING THE MODEL UPDATE TOOL
Select the Tools:Visual C++:Update Model from Code or the Tools:Visual Basic:Update Model from Code menu command.
Follow the steps of the wizard.
The Model Update Tool is shown in Figure B-7.
