Hi Steve,

You cannot add it to the form this way but you can store reference to the object in the form's property.

thisform.AddProperty("oPinPad", createobject("rpreader.rppinpad"))

>I get the error "OLE error code 0x800004002 : no such interface supported."
>when I try to use AddObject.

> thisform.AddObject("oPinPad","OLEControl","rpreader.rppinpad")
