>Bit of a project management problem here. I've got a class in my VFP6 and it opens fine in the project manager, however I've got a different project in VFP5 and it contains all the same files. However when opening my class within my class library I get the following error

>path/classlibname.vcx is not an object file

You cannot use the same class library in VFP5 and VFP6. Make a copy of your class library for VFP5 project and recompile it under VFP 5 using COMPILE CLASSLIB classlibname.

>Why... When running the VFP5 executable I do get an error on the property readonly, which is assigned on the init for text boxes and a spinner, this does not happen in VFP6, anybody any ideas??

Maybe VFP5 text boxes and spinners don't have ReadOnly property yet?
