VB supports something called "default" properties (I believe that's the name but I am not 100% sure.)

Anyway, the idea is that sometimes when you reference an object in VB, for example a texbox, you can say txtName = "Joe" and VB will automatically assign the value to the "default" property of the textbox, for example to txtName.value = "Joe"

VFP does not support these "default" properties. What you need to do is find out what is the "default" property for the object that you are trying to use and reference that property explicitly.
