Word Solutions

Visual Studio 2010 provides project templates you can use to create document-level customizations and application-level add-ins for Microsoft Office Word. You can use these solutions to automate Word, extend Word features, and customize the Word user interface (UI). For more information about the differences between document-level customizations and application-level add-ins, see Office Solutions Development Overview.

Applies to: The information in this topic applies to document-level projects and application-level projects for Word 2007 and Word 2010. For more information, see Features Available by Office Application and Project Type.

This topic provides the following information:

• Automating Word.

• Developing document-level customizations for Word.

• Developing application-level add-ins for Word.

• Customizing the user interface of Word.

Automating Word

The Word object model exposes many types that you can use to automate Word. For example, you can programmatically create tables, format documents, and set the text in ranges and paragraphs. For more information, see Word Object Model Overview.

When developing Word solutions in Visual Studio 2010, you can also use host items and host controls in your solutions. These are objects that extend certain commonly used objects in the Word object model, such as the Microsoft.Office.Interop.Word.Document and Microsoft.Office.Interop.Word.ContentControl objects. The extended objects behave like the Word objects they are based on, but they add additional events and data binding capabilities to the objects. For more information, see Automating Word by Using Extended Objects.

Developing Document-Level Customizations for Word

A document-level customization for Microsoft Office Word consists of an assembly that is associated with a specific document. The assembly typically extends the document by customizing the user interface (UI) and by automating Word. Unlike an application-level add-in, which is associated with Word itself, functionality that you implement in a customization is available only when the associated document is open in Word.

To create a document-level customization project for Word, use the Word Document or Word Template project templates in the New Project dialog box of Visual Studio. For more information, see How to: Create Office Projects in Visual Studio.

For more information about how document-level customizations work, Architecture of Document-Level Customizations.

Word Customization Programming Model

When you create a document-level project for Word, Visual Studio generates a class, called ThisDocument, which is the foundation of your solution. This class represents the document that is associated with your solution, and it provides a starting point for writing your code.

For more information about the ThisDocument class and other features you can use in a document-level project, see Programming Document-Level Customizations.

Developing Application-Level Add-ins for Word

An application-level add-in for Microsoft Office Word consists of an assembly that is loaded by Word. The assembly typically extends Word by customizing the user interface (UI) and by automating Word. Unlike a document-level customization, which is associated with a specific document, functionality that you implement in an add-in is not restricted to any single document.

To create an application-level add-in project for Word, use the Word Add-in project templates in the New Project dialog box of Visual Studio. For more information, see How to: Create Office Projects in Visual Studio.

For general information about how application-level add-ins work, see Architecture of Application-Level Add-Ins.

Word Add-in Programming Model

When you create a Word add-in project, Visual Studio generates a class, called ThisAddIn, which is the foundation of your solution. This class provides a starting point for writing your code, and it also exposes the object model of Word to your add-in.

For more information about the ThisAddIn class and other features you can use in an add-in, see Programming Application-Level Add-Ins.

Customizing the User Interface of Word

There are several different ways to customize the user interface of Word. Some options are available to all project types, and other options are available only to application-level add-ins or document-level customizations.
