>In research here on the UT there was a message from Gary Winkler dated 8/19/97 in which Gary said he usually found the problem was in - an incorrectly spelled field name in a controlsource. So I tried creating a new Form using the Form Designer with just ONE field on it. I set the DE to a table and dragged one field from the DE to the Form to create the field. Then I saved the Form normally then did a File / Save as Class – just like I did above, into the apclases.vcx. The new class was listed in the Project Manager / Classes and also showed up in the Class Browser just like the above class did.

John,

In the main of your program do you open all your classlibs? If you are testing
you may need to open it yourself.

SET CLASSLIB TO APSCLASES ADDITIVE
oForm = CREATEOBJECT("yellow_card")

If it can't find it then, check your search path. VFP may not be able to find your classlib to open.
