IVI issue fo PXI 2532 based on VB.NET

[CLU883R]

I using PXI2532 based on VB.net programing to control the switch box.  I had posted another question ashttp://forums.ni.com/ni/board/message?board.id=320&thread.id=1362 before. That isuee had solved well.

But when I transfer my program code to another PC, I met another issue. I found a error as:

-------------------------------------------------------------------------------------------------------------

Public Shared Function ThrowError(ByVal handle As System.IntPtr, ByVal code As Integer) As Integer
            Dim status As Integer
            Dim size As Integer = PInvoke.GetError(handle, status, 0, Nothing)
            Dim msg As System.Text.StringBuilder = New System.Text.StringBuilder   
            If (size >= 0) Then
                msg.Capacity = size
                PInvoke.GetError(handle, status, size, msg)
            End If
            Throw New System.Runtime.InteropServices.ExternalException(msg.ToString, code)
        End Function
    End Class
End Class

-----------------------------------------------------------------------------------------------------

There is a external exception in blue part. It says:

"Invalid resource name.    If the resource descriptor is an IVI name, it must match the entry in the IVI Configuration Store in a case sensitive manner. "

I try to run a NI exampl in VB.net http://zone.ni.com/devzone/cda/epd/p/id/4577.

There is a error in same code. It says

"Insufficient location information or the device or resource is not present in the system.    Common errors when initializing a session:  - Mismatch between the device and topology.  - Resource descriptor is a device that is not a switch.  - Chassis not powered on."

I check this page for help:

http://zone.ni.com/devzone/cda/tut/p/id/4562.

But  I can't used none of two method to deal with this, for

I can't add "niSwitch_32.dll" as a  reference cause I used VB.net.

I can't find measurement studio , instrument driver cause I'm unable to use measurement studio.

Does anybody have idea? PLZ help

the code I had meantioned is a part of niSwitch.vb.

Hi C.,

Verify the resource descriptor in the program is identical to the resource descriptor in MAX.

Program Resource Descriptor:

 

MAX Resource Descriptor:

 

Hope this helps!

What does the Measurement and Automation explorer say your switch device name is? Does it match what you're passing to the initialize function?

(edit to add: what Chad says above)
