Welcome to the Microsoft® Visio® Managed Code Interop Tutorial. You can browse the lessons online or download the entire tutorial, which includes the lessons as well as the accompanying Microsoft Visual Basic® .NET projects, to your desktop.

This tutorial describes how to build a Visio solution written in Visual Basic .NET. It steps through the process and code required to create a Visio Component Object Model (COM) add-in in Visual Basic .NET, handles events, gathers input via a wizard interface to autogenerate a drawing, and enhances performance. Each lesson topic includes a Visual Basic .NET sample application that implements the topic functionality. Each lesson�s application can be compiled into a COM add-in that runs in Visio 2002. Each lesson's application demonstrates how to incrementally add the topic functionality for the lesson to the functionality in the previous lesson�s application.

This tutorial consists of documentation and Visual Basic .NET projects that support the topics described in the following lessons:

• Lesson 1: Visio COM Add-in Creation in Visual Basic .NET

• Lesson 2: Event Handling

• Lesson 3: Data Input

• In this lesson we extend the COM add-in from Lesson 2: Event Handling to invoke a wizard that gathers user preferences for creating a simple flowchart. Through the wizard, the user can determine the number of flowchart shapes to draw and modify shape properties. We extend the
• DocumentCreator
• class from the previous lesson so that the COM add-in creates a
• DocumentCreator
• object using the wizard data.

• Lesson 4: Performance

• Instead of setting shape properties individually on the
• Shape
• object, resulting in two calls per property for each shape, you can use the Visio
• SetFormulas
• method to modify ShapeSheet® cells in a single call by specifying an array of values and cells.
