<p>Welcome to using Phidgets with Visual Basic .NET! By using Visual Basic .NET, you will have access to the complete Phidget22 API, including events.</p>
<p>Visual Studio is an IDE provided by Microsoft that can be used to develop code in a wide variety of programming languages, including Visual Basic .NET.</p>
</div>
</div>
</div>

<div class="phd-slide">
<h2>Requirements</h2>

<p>First, make sure you have the following installed:</p>

<p>● Phidgets Drivers for Windows (see Part 1 of this user guide)</p>

<p>● Microsoft Visual Studio</p>

<br />

<h2>Nuget</h2>

<p>
The Phidget22.NET library is now available on nuget.org <span>[https://www.nuget.org/packages/Phidget22.NET/ here]</span>. Nuget is the recommended way to
install and use the .NET library in Visual Studio. The nuget package bundles the C library on Windows, so there are no other prerequisites that need to be
installed. The nuget package adds targets for .NET Core and .NET Standard, so it should be usable from almost any .NET environment which also supports the C
library.
</p>
</div>

<div class="phd-slide">
<h2>Use Our Examples</h2>

<p>One of the best ways to start programming with Phidgets is to use our example code as a guide.</p>

<p>● <span>[https://www.phidgets.com/?view=code_samples&lang=VBNET VB.Net Code Samples]</span></p>

<p>
Download the example(s) that correspond to your Phidget's channel classes. You can find them listed on the enclosure in most cases, or on the <b>API</b> tab of
the product page.
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_VBNET_WIN_VS/-x230/50/channel_class.jpg"></div>
</div>

<div class="phd-slide">
<h2>Use Our Examples</h2>

<p>Unpack and open the example project and click the <b>Start</b> button:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_VBNET_WIN_VS/-x65/50/visualstudio_run.png"></div>

<p>
The application will open the Phidget, list basic information about the Phidget, and demonstrate the Phidget's functionality. Here is an example of a Digital
Output channel on a RFID Phidget:
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_VBNET_WIN_VS/-x150/50/visualstudio_rfid.png"></div>

<p>
You should now have the example up and running for your device. This would be a good time to play around with the device and experiment with some of its
functionality.
</p>
</div>

<div class="phd-slide">
<h2>Editing the Examples</h2>

<p>
The Visual Basic .Net examples are derived from the Windows <span>[https://www.phidgets.com/docs/Phidget_Control_Panel Phidget Control Panel]</span>, so you'll
need to modify a few things to adapt them for your own purposes. To begin with, you can remove the following line:
</p>

<pre data-syntax-language="vbnet">commandLineData phidgetParameters = open.parseCmdLine(); //get command line parameters</pre>

<p>Then, you can modify any line that mentions <b>phidgetParameters</b> by setting it to the desired value instead of using PhidgetParameters object...</p>
</div>

<div class="phd-slide">
<h2>Editing the Examples</h2>

<p>For instance:</p>

<pre data-syntax-language="vbnet">
Try 'set all the values grabbed from command line. these values have defaults that are set in ExampleUtils.vb, you can check there to see them
device.Channel = phidgetParameters.Channel 'selects the channel on the device to open
device.DeviceSerialNumber = phidgetParameters.SerialNumber 'selects the device or hub to open
device.HubPort = phidgetParameters.HubPort 'selects th eport on the hub to open
device.IsHubPortDevice = phidgetParameters.isHubPortDevice 'is the device a port on a vint hub?

If phidgetParameters.isRemote Then 'are we trying to open a remote device?
device.IsRemote = True
Net.EnableServerDiscovery(ServerType.Device) 'turn on network scan
If phidgetParameters.Password <> vbNullString And
phidgetParameters.ServerName <> vbNullString Then

Net.SetServerPassword(phidgetParameters.ServerName, phidgetParameters.Password)
End If
Else
device.IsLocal = True
End If

device.Open() 'open the device specified by the above parameters
Catch ex As PhidgetException
errorBox.addMessage("Error opening the device: " + ex.Message)
End Try</pre
>

<p>Might become:</p>

<pre data-syntax-language="vbnet">
Try
device.Channel = 0
device.DeviceSerialNumber = 370097
device.HubPort = 0
device.IsHubPortDevice = True
device.IsLocal = True

device.Open()
Catch ex As PhidgetException
errorBox.addMessage("Error opening the device: " + ex.Message)
End Try</pre
>

<p>You can then manipulate the rest of the code as your application requires.</p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<p>
You now have working examples and a project that is configured. This teaching section will help you understand how the examples were written so you can start
writing your own code.
</p>

<p>Remember: your main reference for writing VB.NET code will be:</p>

<p>● The <span>[https://www.phidgets.com/?view=api Phidget22 API]</span> documentation</p>

<p>● The <span>[https://www.phidgets.com/?view=code_samples&lang=VBNET VB.Net Example Code]</span></p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<h3>Step One: Create And Address</h3>

<p>You will need to declare your Phidget object in your code. For example, we can declare a digital input object like this:</p>

<pre data-syntax-language="vbnet">ch = New Phidget22.DigitalInput()</pre>

<p>Next, we can address which Phidget we want to connect to by setting parameters such as <b>DeviceSerialNumber</b>.</p>

<pre data-syntax-language="vbnet">ch.DeviceSerialNumber = 496911</pre>

<p>
You can find information about all available parameters <span>[https://www.phidgets.com/docs/Addressing_Phidgets here]</span> or in the API documentation.
</p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<h3>Step One: Create And Address</h3>

<p>
Although we will not discuss it in-depth on this page, you should include
<span>[https://www.phidgets.com/docs/Handling_Errors_and_Logging error handling]</span> for all Phidget functions. Here is an example of the previous code with
error handling:
</p>

<pre data-syntax-language="vbnet">
Try
ch = New Phidget22.DigitalInput()
ch.DeviceSerialNumber = 496911
Catch ex As PhidgetException
errorBox.addMessage("Error initializing: " + ex.Message)
End Try</pre
>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<h3>Step Two: Open And Wait For Attachment</h3>

<p>After we have specified which Phidget to connect to, we can open the Phidget object like this:</p>

<pre data-syntax-language="vbnet">ch.Open(5000)</pre>

<p>
To use a Phidget, it must be plugged in (attached). We can handle this by calling <b>Open(timeout)</b>, which will block indefinitely until a connection is
made, or until the timeout value is exceeded. Simply calling Open does not guarantee you can use the Phidget immediately.
</p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<p>Alternately, you could verify the device is attached by using event driven programming and tracking the attach events.</p>

<p>To use events to handle attachments, we have to modify our code slightly:</p>

<pre data-syntax-language="vbnet">
Private Sub device_Attach(ByVal sender As Object, ByVal e As Phidget22.Events.AttachEventArgs) Handles ch.Attach
Console.WriteLine("Phidget Attached!");
End Sub</pre
>

<p>
We recommend using this attach handler to set any initialization parameters for the channel such as DataInterval and ChangeTrigger from within the
AttachHandler, so the parameters are set as soon as the device becomes available.
</p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<h3>Step Three: Do Things With The Phidget</h3>

<p>
We recommend the use of event driven programming when working with Phidgets. In a similar way to handling an attach event as described above, we can also add an
event handler for a state change event:
</p>

<pre data-syntax-language="vbnet">
Private Sub device_DigitalInputChange(ByVal sender As Object, ByVal e As Phidget22.Events.DigitalInputStateChangeEventArgs) Handles ch.StateChange
stateText.Text = "State: " + e.State;
End Sub</pre
>

<p>
If you are using multiple Phidgets in your program, check out our page on
<span>[https://www.phidgets.com/docs/Using_Multiple_Phidgets Using Multiple Phidgets]</span> for information on how to properly address them and use them in
events.
</p>

<p>If events do not suit your needs, you can also poll the device directly for data using code like this:</p>

<pre data-syntax-language="vbnet">
state= device.State;
stateText.Text = "State: " + e.State;</pre
>

<p>
<b>Important Note:</b> There will be a period of time between the attachment of a Phidget sensor and the availability of the first data from the device. Any
attempts to get this data before it is ready will result in an exception. See more information on this on our page for
<span>[https://www.phidgets.com/docs/Unknown_Values Unknown Values]</span>.
</p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<h3>Step Three: Do Things With The Phidget</h3>

<p>
<b>Enumerations:</b> Some Phidget devices have functions that deal with specific predefined values called enumerations. Enumerations commonly provide readable
names to a set of numbered options.
</p>

<p>Enumerations with Phidgets in Visual Basic .NET will take the form of <b>Phidget22.EnumerationType.Enumeration_Name</b>.</p>

<p>For example, specifying a SensorType to use the 1142 for a voltage input would look like:</p>

<pre data-syntax-language="vbnet">Phidget22.VoltageSensorType.PN_1142</pre>

<p>and specifying a K-Type thermocouple for a temperature sensor would be:</p>

<pre data-syntax-language="vbnet">Phidget22.ThermocoupleType.K</pre>

<p>The Phidget error code for timing out could be specified as:</p>

<pre data-syntax-language="vbnet">Phidget22.ErrorCode.Timeout</pre>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<h3>Step Four: Close And Delete</h3>

<p>At the end of your program, be sure to close and delete your device:</p>

<pre data-syntax-language="vbnet">device.Close();</pre>
</div>

<div class="phd-slide">
<h2>Setting up a New Project</h2>

<p>
When you are building a project from scratch, or adding Phidget functionality to an existing project, you'll need to configure your development environment to
properly link the Phidget .NET library. To begin:
</p>

<p>Create a new Windows Forms Application project:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_VBNET_WIN_VS/-x290/50/Vbnet_newproject.png"></div>
</div>

<div class="phd-slide">
<h2>Setting up a New Project</h2>

<p>Next, right-click to add a reference to the Phidget .NET library:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_VBNET_WIN_VS/Add_Reference.png"></div>
</div>

<div class="phd-slide">
<h2>Setting up a New Project</h2>

<p>On the following screen, click <b>Browse</b> and navigate to the location of Phidget22.NET.dll:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_VBNET_WIN_VS/Add_Reference_2.png"></div>
</div>

<div class="phd-slide">
<h2>Setting up a New Project</h2>

<p>Finally, to include the Phidget .NET library, add the following lines to main window class file:</p>

<pre data-syntax-language="vbnet">
Imports Phidget22
Imports Phidget22.Events</pre
>

<p>Success! The project now has access to Phidgets.</p>
</div>

<div class="phd-slide">
<h2>What's Next?</h2>

<p>{{Slide_Deck_PT3_Outro}}</p>
</div>
