>I have code in the init method of a form:
>THISFORM.ADDOBJECT("oFILE","FILE")
>where "FILE" is a 'custom' class.
>I get the error 'object class is invalid for this container'
>the code worked in 5.0a and actually worked in 6.0 when running from the project manager where the calling program said simply 'do form xyz.' When I create the app or the exe it blows up. I know one is not supposed to add a form to a class but this is adding a class to a form. Any ideas? TIA Bob

Both FILE and FILE() are VFP keywords, which makes them an extremely risky choice for class names. This is the source of your problem.
