I'm not sure what you are asking. See if AINSTANCE() or AVCXCLASSES( ) will help you. If you don't know if newclass exists, you may have to set ON ERROR before CREATEOBJECT() then check to see if the object was created then reset on error.




>Is there any function like

IsDefined("MyClass")

that tells me if MyClass is defined? I need this function in a loop where the class name is constructed at runtime and, if defined, an object will be instantiated. e.g.
>

>for Loop = 1 to MaxClass
>  NewClass = ConstructClassName(Loop)
>  if IsDefined(NewClass)
>    oObject = CreateObject(NewClass)
>    * do something
>  end
>endfor
