XL: Not All Worksheet Functions Supported as Application

• Microsoft Excel for Windows, versions 5.0, 5.0c
• Microsoft Excel for the Macintosh, versions 5.0, 5.0a
• Microsoft Excel for Windows NT, version 5.0
• Microsoft Excel for Windows 95, versions 7.0, 7.0a
• Microsoft Excel 97 for Windows
• Microsoft Excel 98 Macintosh Edition

SUMMARY

In Microsoft Visual Basic for Applications, not all Microsoft Excel worksheet functions are supported as methods of the Application object. If you attempt to use one of these worksheet functions with the Application object, you will receive the following error message:

   Run-Time Error '438':
   Object doesn't support this property or method

MORE INFORMATION

You can write Visual Basic procedures that call Microsoft Excel worksheet functions. The worksheet functions that are available to Visual Basic procedures are in the Application object, and are listed in the Methods/Properties list for the Application object in the Visual Basic Object Browser.

Most worksheet functions that are not available as methods of the Application object have an equivalent Microsoft Visual Basic built-in operator or function. For example, the Mod() worksheet function is not available as a method of the Application object because there is an equivalent Mod operator built-in to Visual Basic. This is by design, because a Visual Basic operator works faster than a Microsoft Excel function in a Visual Basic module.

Using the Visual Basic equivalent operator or function is preferred for increased speed and flexibility in calculations. Additionally, the Visual Basic operator or function is available to all applications that use Microsoft Visual Basic for Applications.

Although it is recommended that you use the Visual Basic operators or functions shown in the list above, there are alternative methods for using the worksheet functions in a Visual Basic macro if necessary. As an example, you can use the ATAN worksheet in your Visual Basic macro using the ExecuteExcel4Macro or Evaluate functions:

   x = Application.ExecuteExcel4Macro("Atan(12)")

    -or-

   x = Application.Evaluate("Atan(12)")
