Visual Basic .NET - API Bindings

The Visual Basic .NET bindings allow you to control Bricks and Bricklets from your Visual Basic .NET programs. The ZIP file for the bindings contains:

  • Tinkerforge.dll, a precompiled .NET library
  • Tinkerforge.xml, the API documentation for Visual Studio, MonoDevelop, etc
  • in source/ the source code of Tinkerforge.dll
  • in examples/ the examples for every Brick and Bricklet

The Visual Basic .NET bindings are based on the C# bindings. Since version 2.0.0 the C# bindings are CLS compliant. This allows to use them with all .NET compatible languages, such as Visual Basic .NET.

Requirements

  • Visual Basic 2005 (VB 8.0) or newer, or Mono 1.2.3 or newer

Installation

If and how the Visual Basic .NET bindings have to be installed depends heavily on how you are going to use them. If you are just calling the Visual Basic .NET compiler from the command line then you can just put the Tinkerforge.dll file into the same folder as the Visual Basic .NET code of your program.

To use the bindings in an IDE you'll probably have to add the Tinkerforge.dll file to the assembly catalog of the IDE. How this is done depends on the IDE and will be explained in documentation of that IDE.

Testing an Example

To test a Visual Basic .NET example Brick Daemon and Brick Viewer have to be installed first. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon and helps to figure out basic information about the connected Bricks and Bricklets.

MonoDevelop

As an example we will compile the Stepper Brick configuration example with the Visual Basic .NET Compiler (VBNC) that comes with Mono. Create a new Visual Basic .NET project in MonoDevelop by clicking:

  • File
  • New
  • Solution...
  • Choose "VBNet"
  • Choose "Console Project"
  • Choose a name (e.g. ExampleConfiguration)
  • Click Forward
  • Click OK

MonoDevelop should show an Application.vb file in its editor. Replace its content with the content from ExampleConfiguration.vb file in the examples\Brick\Stepper\ folder.

In the example HOST and PORT specify at which network address the Stepper Brick can be found. If it is connected locally to USB then localhost and 4223 is correct. The UID value has to be changed to the UID of the connected Stepper Brick, which you can figure out using Brick Viewer:

Const HOST As String = "localhost"
Const PORT As Integer = 4223
Const UID As String = "XYZ" ' Change to your UID

Now add Tinkerforge.dll as a reference to the project:

  • Right click on References in Solution Explorer
  • Edit References...
  • Click on .Net Assembly tab
  • Select Tinkerforge.dll
  • Click Add

The project is now ready for a test, click:

  • Run
  • Run

The Visual Basic .NET Compiler can also be used from the command line:

vbnc /target:exe /out:Example.exe /reference:Tinkerforge.dll ExampleConfiguration.vb

Visual Studio

As an example we will compile the Stepper Brick configuration example with Microsoft Visual Basic 2010. Create a new Visual Basic project by clicking:

  • File
  • New Project...
  • Choose "Visual Basic"
  • Choose "Console Application"
  • Choose a name (e.g. ExampleConfiguration)
  • Click OK

Visual Studio should show an Module1.vb file in its editor. Replace its content with the content from ExampleConfiguration.vb file in the examples\Brick\Stepper\ folder.

In the example HOST and PORT specify at which network address the Stepper Brick can be found. If it is connected locally to USB then localhost and 4223 is correct. The UID value has to be changed to the UID of the connected Stepper Brick, which you can figure out using Brick Viewer:

Const HOST As String = "localhost"
Const PORT As Integer = 4223
Const UID As String = "XYZ" ' Change to your UID

Now add Tinkerforge.dll as a reference to the project:

  • Right click on the project in Solution Explorer
  • Add References...
  • Click on Browse tab
  • Select Tinkerforge.dll
  • Click OK

Before the project can be tested Visual Studio needs to know the correct start object:

  • Right click on the project in Solution Explorer
  • Properties
  • Click on Application tab
  • Select "Sub Main" as start object
  • Click Save

The project is now ready for a test, click:

  • Debug
  • Start Debugging
