Creating and AddIn with XLL Plus for Visual Studio 2008.

XLL+ is a toolkit to aid C/C++ programmers in the construction of Excel add-in libraries. XLL+ contains tools and C++ class libraries that make it very easy and safe to produce high-performance Excel add-ins. The XLL+ class library wraps the Microsoft Excel SDK with simple, intuitive C++ classes, and the Wizards create all the code for you. The user needs very little knowledge of Excel or the SDK. Add-ins produced with XLL+ contain no Visual Basic code; they are authored entirely in C and C++.

The following editions are available:

• XLL Plus for Visual Studio 2008
• XLL Plus for Visual Studio 2005 and Visual Studio 2008
• XLL Plus for Visual Studio 2005
• XLL Plus for Visual Studio 2003 and Visual Studio 2005
• XLL Plus for Visual Studio NET 2003

Updates in V6.3

• Hidden regions
  Almost all of the generated code is now surrounded by #pragma region blocks. This means that almost all of the implementation code for each add-in can be hidden, and you need only see the code that is interesting - the function signature and your own code.
• XLL Wrapper Libraries
  Sometimes it is useful to be able to call your Excel add-in functions from other environments, such as command-line programs or interactive applications, written in C++, Java, C# or Visual Basic. The Xll Wrapper toolkit contains tools, a runtime library, samples and documentation to help with the development of COM modules and .NET assemblies that wrap Excel XLL add-ins. The add-in functions in the library are available as COM and .NET methods to client programs that use the wrapper modules. The wrapper objects can be used by clients written in any development environment that supports COM or .NET, including C++, Java, C#, Visual Basic and VBA.
• Asynchronous functions
  Planatech considerably improved the performance and scalability of the asynchronous function model. You can now place thousands of asynchronous functions in a spreadsheet without degrading performance. They have also added a new sample application which demonstrates how to integrate a data feed into an Excel add-in for high-performance real-time data add-in, written in C++, and which supports array real-time values as well as scalar values.
• Portuguese language support
  Help files can now be generated in any of three languages: English, French and now Portuguese.
• Value Lists
  The Value List Editor is now easier to use. You can copy and paste data to and from the dialog, so it's easy to edit lists in source code or in Excel, and paste them into the Value List Editor.
