Hi Steve,

I don't think you can visually add a class stored in procedure to a form at design time. What you will have to do, is save your class into a VCX. Then, you can hack your form like this:

USE MyFOrm.SCX
replace class with MyTextBox, classloc with MyLib.vcx ;
    for lower(baseclass) = 'textbox'
