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

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

Because of this, you will receive an error message when you run any of thefollowing commands in a procedure in Microsoft Excel or Microsoft VisualBasic:
   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 MicrosoftExcel 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 Excellisted above, it is recommended that you use the application name"Excel.Application" rather than "Excel.Application.5".
