XL: Error Creating OLE Automation Object with Microsoft Excel

ID: Q129252

The information in this article applies to:

SYMPTOMS

When you use the CreateObject function or the GetObject function in a procedure to create or return a Microsoft Excel OLE Automation object, you may receive one of the following error messages.

In Microsoft Excel 97:

   Run-time error '429':
   ActiveX component can't create object

In Microsoft Excel version 7.0:

   Run-time error '499':
   User-defined error

In Microsoft Excel version 5.0:

   Run-time error '440':
   OLE Automation error

CAUSE

This behavior occurs if you use an incorrect value for the class argument of the CreateObject or GetObject function. The class argument consists of the name of the application providing the object (appname) followed by a period and the type of class of object to create or return (objecttype).

The application names "Excel.Application" or "Excel.Application.5" may be used for Microsoft Excel versions 5.0 and 7.0. However, only the application name "Excel.Application" may be used for Microsoft Excel 97.

Because of this, you will receive an error message when you run any of the following commands in a procedure in Microsoft Excel or Microsoft Visual Basic:

   Set myApp = CreateObject("Excel7.Application")

   Set myApp = GetObject(,"Excel7.Application")

   Set myApp = CreateObject("Excel.Application.7")

   Set myApp = GetObject(,"Excel.Application.7")

To avoid receiving an error message when you create or return a Microsoft Excel OLE Automation object, use any of the following commands:

   Set myApp = CreateObject("Excel.Application")

   Set myApp = GetObject(,"Excel.Application")

   Set myApp = CreateObject("Excel.Application.5")

   Set myApp = GetObject(,"Excel.Application.5")

For compatibility between all of the versions of Microsoft Excel listed above, it is recommended that you use the application name "Excel.Application" rather than "Excel.Application.5".
