A VB.Net Winforms postcode lookup example using .Net framework 4.0.

VB.Net code on GitHub

The code was developed in Visual Studio 2012 using .Net framework 4.0 but should work in other versions of Visual Studio and the framework.

The example uses our free AA11AB postcode but it allows the user to select other free postcodes too. Both BasicAddress (Street Level Data) and RapidAddress (Full Property Level Data) are implemented in one Windows Application.
