Step 2 of the wizard obtains further information from the user, which is used to build the new project.
Click on the controls on the picture below to see what they do.
Creates a results cache in the application class. See Function attribute: cacheresults for more information.
Generates code to store the cache to file when the XLL is closed and restore it from file when the XLL is opened.
Generates a CXlMenu in the header file and code to create and destroy the menu in OnXllOpenEx and OnXllClose.
Generates code to create and destroy a toolbar containing one button in OnXllOpenEx and OnXllClose. Adds a bitmap for the button to the application's resource file.
Generates empty implementations of OnXllOpenEx and OnXllClose in the the header and source file..
Decide whether to include a VersionInfo function. This is useful as a library documentation function available from within Excel. Its also a useful test as to whether your library has been built properly.
You can always delete the function later.
These option buttons determine whether (reasonably helpful) comments will be inserted into the skeleton code that the AppWizard produces.
Unless you have a very good reason, and are familiar with the content of XllPlus skeleton code, it is a good idea to keep the comments.
