Microsoft Visual Studio 2005 Tools for the Microsoft Office System (Visual Studio 2005 Tools for Office) makes it possible for you to create rich Microsoft Office 2003–based applications in Microsoft Visual Studio 2005, using the power of Microsoft Office Word 2003 and Microsoft Office Excel 2003. You can take advantage of all the functionality provided by the Word and Excel object models from either Microsoft Visual Basic 2005 or Microsoft Visual C#. Although Visual Basic developers can work comfortably with the objects exposed by the object models, Visual C# developers may experience challenges. Because of the history and the original design of the Office object models, the members of their objects were created with the intent that they would be called by Microsoft Visual Basic for Applications (VBA) code. Therefore, the various properties and methods take advantage of features that are provided by VBA but that do not correspond to Visual C# features. This document discusses issues involved in working with VBA-focused methods and properties for both Word and Excel, and shows examples comparing Visual Basic code and corresponding Visual C# code.
