Read and write Relations, Parameters by VBA or VB.NET.

I apologize, but I'm a novice of Visual Studio.

I was unable in any way, tu run the VB.net example that reside in the Creo installation folder.
(In my case C:\xxx\App\Creo2_M240_64bit\Common_Files\M240\vbapi\vbapi_examples\.
I do not understand how debug, a single *.VB code file...I also tried to open the project VB API Examples.vbproj, but still have a lot of problem, due to that I need to try to debug the example pfcRelationsExamples.vb ??

Instead if I open the Application example C:\xxx\App\Creo2_M240_64bit\Common_Files\M240\vbapi\vbapi_appls\vbparam, the ParameterAndDimension.vbproj I am able to connect with Creo.

What I would like to understand, is how to create a windows form application, to run specific operation to the relations and some parameters, but at this point I have no idea to start from ??.
