Note that in Visual Basic and .NET - and perhaps a few other languages, too - you can refer to an object in a form by its name (perhaps you are confusing this):

// In C#.NET
CalcWeight.Text = ...

In Visual FoxPro, you have to indicate a containership hierarchy, which must start with This, or ThisForm (or an object reference to any object), for example:

* In Visual FoxPro
This.Value = ...
* or:
ThisForm.CalcWeight.Value = ...
