If you plan to run Microsoft Excel with another desktop application that supports Visual Basic, you need the appropriate language version of the object libraries for that desktop application. For example, suppose you want to write Italian code that uses features of both Microsoft Excel and Microsoft Project. To do this, you need the following files:
For the purposes of this example, the language versions of Microsoft Excel and Microsoft Project are unimportant. Your Italian code will work with any version of Microsoft Excel and any version of Microsoft Project, provided that you include the appropriate object libraries (see the preceding list).
For more information about writing code that works with other applications, see Chapter 10, "Communicating with Other Applications."
