如何实例化Ag3497x类?

大家好，我是34972A仪器的新手，我正在尝试创建一个Visual Basic .Net 2010应用程序来从16个通道收集数据并切换一些I / O.
使用Console演示进行教程。
它的工作原理，但它的错误我，我必须这样做：进口Ivi.Visa.Interop进口Agilent.CommandExpert.ScpiNet.Ag3497x_1_13模块模块1分的Main（）“昏暗I34972A作为新Ivi.Visa.Interop.ResourceManager”昏暗I34972A作为
Ag3497x =新Ag3497x（61） 'U***Transport = I34972A.Transport.Visa.ResourceName.Get' 点心I34972A作为Ag3497x =新Ag3497x（U***Transport）Console.WriteLine（ “连接到34972A LXI数据采集/开关单元...”）控制台
.WriteLine（）昏暗I34972A作为Ag3497x =新Ag3497x（ “USB0 :: 0x0957 :: 0x2007 :: my49007650 :: 0 :: INSTR”）昏暗IDN作为字符串=没有I34972A.SCPI.IDN.Query（IDN）Console.WriteLine
（“* IDN查询返回：”＆amp; IDN）Console.WriteLine（）Console.WriteLine（“按任意键退出...”）Console.ReadKey（）End Sub它工作正常，但我想这样做更多
通过识别所有可用的传输（我有3个其他USB仪器）智能地我想以编程方式发现传输名称。
我不知道如何实例化Ag3497x类，所以我可以访问所有的方法和属性。
上面我被迫输入一个字符串“USB0 :: 0x0957 ....”我想发现有多少设备连接并选择适当的传输。
我不想硬编码。
有没有人知道如何：1。实例化“新”类2.以编程方式发现所有可用的传输3.打开传输4.向其写入数据5.关闭传输。
我非常感谢您提供的任何帮助！

  Hi All,

I am new to the 34972A instrument, and I am trying to create a Visual Basic .Net 2010 application to Gather data from 16 channels and to toggle some I/O.

Ran a tutorial using the Console demo.  It works, but it bugs me that I have to do this:

Imports Ivi.Visa.Interop
Imports Agilent.CommandExpert.ScpiNet.Ag3497x_1_13

Module Module1

    Sub Main()

        'Dim I34972A As New Ivi.Visa.Interop.ResourceManager
        'Dim I34972A As Ag3497x = New Ag3497x(LXI)
        'U***Transport = I34972A.Transport.Visa.ResourceName.Get
        'Dim I34972A As Ag3497x = New Ag3497x(U***Transport)


        Console.WriteLine("Connecting to 34972A LXI Data Acquisition/Switch Unit...")
        Console.WriteLine()

        Dim I34972A As Ag3497x = New Ag3497x("USB0::0x0957::0x2007::my49007650::0::INSTR")
        Dim IDN As String = Nothing

        I34972A.SCPI.IDN.Query(IDN)

        Console.WriteLine("*IDN query returns: " & IDN)
        Console.WriteLine()
        Console.WriteLine(" Press any key to exit...")
        Console.ReadKey()
    End Sub

It works fine, but I want to do this more intelligently by identifying all available transports ( I have 3 other USB instruments)

I want to programmatically discover what the transport name is.

I don't know how to instantiate Ag3497x class so I have access to all the methods and properties.  Above I am forced to enter a string "USB0::0x0957...."  I want to discover how many devices are connected and choose the appropriate transport.  I don't want to hard code it.

Does any one know how to :

1. instantiate the "new" class
2. programmatically discover all available transports
3. open the transport
4. Write data to it  
5. close the transport.

I would really appreciate any help you can provide!
