How to Download and Use the Microsoft Office 12 Object Library
The Microsoft Office 12 Object Library is a set of primary interop assemblies (PIAs) that enable you to use the features of Microsoft Office 2007 applications from Visual Studio projects. The PIAs allow managed code to interact with the COM-based object models of Office applications.
In this article, you will learn how to download and use the Microsoft Office 12 Object Library in your Visual Studio projects.
Downloading the Microsoft Office 12 Object Library
To download the Microsoft Office 12 Object Library, you need to have Microsoft Office 2007 installed on your computer. If you don't have Office 2007, you can download a trial version from here.
Once you have Office 2007 installed, you can download the Microsoft Office 2007 Primary Interop Assemblies Redistributable from here. This package contains the PIAs for all Office 2007 applications, including Word, Excel, PowerPoint, Outlook, Access, and more.
After you download the package, run the setup file and follow the instructions to install the PIAs on your computer. The PIAs will be added to a folder in the program files directory and also registered in the global assembly cache.
Using the Microsoft Office 12 Object Library in Visual Studio Projects
To use the features of an Office 2007 application in your Visual Studio project, you need to add a reference to the corresponding PIA. For example, if you want to use Word features in your project, you need to add a reference to the Microsoft Word 12.0 Object Library.
To add a reference to an Office PIA, follow these steps:
In Visual Studio, open or create a project that targets the .NET Framework.
In Solution Explorer, right-click the project node and click Add Reference.
In the Add Reference dialog box, click the COM tab.
In the list of available references, find and select the PIA that corresponds to the Office application that you want to use. For example, select Microsoft Word 12.0 Object Library if you want to use Word features.
Click OK to add the reference to your project.
Your Visual Studio project now has a reference to the application's PIA. You can use the Object Browser (press F2) or IntelliSense to explore the objects, methods, and properties that are provided by the PIA. You can also use the documentation for the Office object library reference [^1^] for more information about how to use the PIA in your code.
In this article, you learned how to download and use the Microsoft Office 12 Object Library in your Visual Studio projects. By using the PIAs for Office 2007 applications, you can access and manipulate various features of Office documents and data from your managed code. 29c81ba772
