Visual Studio .NET integration
With the Microsoft Office InfoPath 2003 Toolkit for Visual Studio .NET, which can be downloaded from the Microsoft Developer Network (MSDN) Web site, you can use Microsoft Visual Studio .NET 2003 to create, debug, and build Microsoft Office InfoPath 2003 projects that use Microsoft Visual C# or Microsoft Visual Basic .NET managed code. By using a combination of InfoPath to design forms and Visual Studio .NET to write code, you can build your project in debug or release mode. You can create new forms or add managed code to existing ones.
