I just retested my code I sent him. Works fine. Sets the label's caption:

I created a Control class and dropped a label on it

I added a property called 'builder' and set it to MyBuilder.prg

I created the prg MyBuilder and added the following code:

LPARAMETERS oObject, cButton

cCaption = INPUTBOX("Enter a caption")

oObject.label1.Caption = cCaption

RETURN
