>>I've got a VFP 9 app. that has some hook points in it to let me override existing behavior via an EXECSCRIPT call on a memo field. The problem I've run into is when I want to call an existing class library (that is built into the EXE and has SET CLASSLIB set) from within the EXECSCRIPT code. VFP fails saying it can't find the class. I modified the syntax to use NEWOBJECT() instead, e.g. NEWOBJECT("MyClass", "MyLibrary", "MyExe.EXE"). That fails with an "Invalid file descriptor". I've checked to make sure that the SET CLASSLIB is set (which it is), but still no luck.

Yeah, you'd think that would work, wouldn't you?

You get a "Alias is already in use error".
