Hi Ken,

Thanks for the quick response and your *excellent* explanation of the reasoning behind this.

Should the VFP documentation possibly be enhanced to notate this for these objects, as it does with the Session object?

>Hi Evan. The answer to your question in short is: correct. For more information on this... I designed and wrote the Class Browser for VFP 3.0 and I have updated it for each version, including the enhancements made for VFP 8.0 which were mainly adding the new base classes in VFP 8.0 now supported in the Class Designer (VCX) system. The classes that you list above are classes that can be subclassed in PRG (using DEFINE CLASS) but not in the visual Class Designer (VCX), which is why they are not listed in the Class Browser. If you enter CREATE CLASS in the command window and see the drop down list in that dialog, you will see a list of which classes are available to be subclasses in the Class Designer (VCX) system.
