The LibraryPath property of the Application object in Microsoft Visual Basic for Applications works slightly differently in Microsoft Excel for Windows than it does in Microsoft Excel for the Macintosh. This article explains the differences and how to avoid problems when using the LibraryPath property in your Visual Basic macros and procedures.

More information

You can use the LibraryPath property in Visual Basic macros and procedures in Microsoft Excel to return the path to the Library folder. The Library folder is the folder where most add-ins included with Microsoft Excel are stored.

In Microsoft Excel for Windows, the LibraryPath property appears similar to the following:
   C:\Program Files\Microsoft Office\Office\Library
Note that there is no trailing separator (in this case, a backslash) at the end of the path.

However, in Microsoft Excel for the Macintosh, the LibraryPath property appears similar to the following:
   Macintosh HD:Microsoft Office:Microsoft Excel 5:Macro Library:
   Macintosh HD:Microsoft Office 98:Office:Excel Add-Ins:
Note that there is a trailing separator (in this case, a colon) at the end of the path. This may cause problems if you are writing code that is intended to work in both Microsoft Excel for Windows and Microsoft Excel for the Macintosh.

You can prevent problems from occurring by programmatically removing the trailing separator from the LibraryPath before you use it. The following example demonstrates one way in which this may be done.

Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

Sample Visual Basic Procedure

   Sub GetGoodLibraryPath()

      ' Store the LibraryPath in a variable.
      xLibraryPath = Application.LibraryPath

      ' If the LibraryPath ends in a colon...
      If Right(xLibraryPath, 1) = ":" Then

         ' ...remove the colon from the end of the path.
         xLibraryPath = Left(xLibraryPath, Len(xLibraryPath) - 1)

      End If

      ' Display the corrected LibraryPath.
      MsgBox "The application's LibraryPath is " & xLibraryPath

   End Sub
Once you have corrected the LibraryPath, you can use the PathSeparator property to add either a backslash or a colon to the end of the path, and then add a file name after the separator. Following is an example:
   xFilePath = xLibraryPath & Application.PathSeparator & "Addin.xla"
If you use the PathSeparator property when the LibraryPath has not been corrected, you may receive an error message when you run the macro in Microsoft Excel for the Macintosh.
