The problem is because you are adding a property to the form. Properties are not part of the form WRT to being able to display. Only objects added via CreateObject/NewObject will be able to participate in the display.

> Thisform.oProductkop(lcteller)= newobject("productkop","Std_veld.vcx")
> WITH Thisform.oProductkop(lcTeller)
> .top =Thisform.Grid1.top - 90
> .left = Thisform.Grid1.left +(lcteller*60)
> .visible = .T.
> .tabindex = 100 + lcteller
> ENDWITH

>All works fine; the objects are added to the form, the properties are set correctly, but the objects are NOT VISIBLE on the screen and therefore useless.
