Categories

There are many different versions of the XLL+ run-time libraries, each suiting a different set of requirements. The categories of choice are listed below. Some of these choices are made when the XLL+ AppWizard is run; others can be made later, by changing the configuration settings of the project.

Class library

The runtime libraries make use of a number of C++ string and collection classes. If you need to use the Microsoft Foundation Classes in your add-in, you should choose MFC; otherwise, choose STL.

C Runtime Libraries (CRT)

You can choose to use the C runtime libraries in a shared DLL (Multithreaded DLL), or you can choose to have all the required C runtime functions built into your add-in (Multithreaded).

CLR support

You can choose to use the Common Language Runtime (.NET) libraries. If you do so, you must use the shared DLL C Runtime Libraries.

Character set

You can select the Unicode character set or the standard MBCS character set for your add-in.

Configuration

There are different runtime libraries for Debug and for Release configurations.

Library inclusion

Generally, the correct XLL+ run-time library will be included automatically. The header file xlplib.h is included as part of xllplus.h. It contains a list of #pragma comment(lib, [libname]) statements, which select the appropriate library and bind it to the add-in.

The selection is driven by the macros listed below. Note that one of XLL_LIB_MFC or XLL_LIB_STLmust be defined. If neither is defined, then the project will not build. One these two macros is defined when you create the project using the XLL+ AppWizard.

If you wish to use a different run-time library (or a special build), then you should add XLL_NO_LIBS to the list of C/C++ Preprocessor Definitions for the project, and you should add the name of the desired library in the list of Linker Additional Dependencies.

Note that if you select /MT or /MTd with MFC under Visual Studio .NET 2003, you must also add _USRDLL to the list of pre-processor definitions.
