Hi

Is there anyone who has experience with programming of BlinkStick Flex in Visual Studio 2017/2015 using [VB.net](http://VB.net)?

Can anyone give an example?

Sincerely  
Bjarne

There are a lot of examples in C# so it should be very easy to translate them to [VB.NET](http://VB.NET):

Let me know if you still have trouble using BlinkStick and I will provide some [VB.NET](http://VB.NET) examples.

Thanks

I have tried with this code, but it causes an error with “Blinkstick.FindFirst()”.

BC30491 Visual Basic AND [VB.NET](http://VB.NET) Expression does not produce a value.

Imports BlinkStickDotNet

Dim device As BlinkStick = BlinkStick.FindFirst()  
If device IsNot Nothing Then  
If device.OpenDevice() Then  
device.TurnOff()  
Console.WriteLine(“BlinkStick was turned off”)  
Else  
Console.WriteLine(“Could not open the device”)  
End If  
Else  
Console.WriteLine(“BlinkStick not found”)  
End If

Hi

Has anyone as yet got any real [vb.net](http://vb.net) examples ?

I am running VS2019 - [Vb.net](http://Vb.net), cant get the VB6 examples working either- due to an automation error.

The blinkstick would be idea but just doesnt work, i could embed via the web api, little long winded but that wont allow you to set the index of the colour light, only turn all red/etc not allow me to specify which led i want to turn on / off which was the original idea

help would be good, thanks
