Reading and writing from VB.net Text boxes to network variables

[Dhomfray]

Using VS13 and Latest Measurement Studio

Has anyone got an example, I have tried all day and failed.

I have a LabVIEW program as follows

I really need a VB.NET form that reads Network_Double to TextBox1.Text and writes from TextBox2.Text to Network_String

There seems to be no examples for this basic thing, they all seem to be binding from Network Variables to National Instruments components but not to native VB components. 

This sort of thing must be a doddle for someone
