Programming PhidgetAnalog 4 Output with C#

[yoni]

hi all,
i new with C# coding and i am trying to create a simple gui to a phidget analog 4 output.
i downloaded the relevant code example and tried to add radio buttons so the user will be able to configure all 4 channels.
i read the api documentation and how to open and attach a channel,
but i could attach to the channel.
can someone help with the correct syntax to do so?
thanks in advance.
