Error 1172 occured at invoke node

[omerbashir]

Hello

I am new to Labview and object oriented programming. I have an already written c# code which communicates with a digital I/O card attached to a test system. I want to run those c# functions in labview. I am using .NET constructor pallett and then invoke node but I am receiving following Error:

Error 1172 occurred at Invoke Node Error calling method DmmCSharp.Handler.Reset, (System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
    Inner Exception: System.Runtime.InteropServices.COMException: KtMDsr: A connection to the instrument has not been established.)

Image file of error and vi file is attached below.

The clue is in the 'A connection to the device has not been established'. You are trying to reset the device - presumably without having first configured the appropriate parameters or opened connection to it so the library is probably throwing that error.
