Although the Add-In model in Visual Basic 4 was a great boon, it lacked important capabilities. There was no way to move between modules within a project, although you could send keystrokes to the project window. There was no access to the code in modules. Again, you could work around this either by using the InsertFile method on the Component or FormTemplate objects to add code immediately after the declarations section or by directly manipulating the text files and then reloading them. However, you can modify Visual Basic 5 to work the way you want it to; you can enforce corporate styles, add comment templates, and add standard error handlers. Or you can specify your ideal development environment and then build it by writing add-ins and modifying the IDE with personalized toolbars.
