While using zxing dll for reading barcode, i need to create an instance for barcode format list, but while doing so i m getting following error

 

"Error 1172 occurred at Invoke Node System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
Inner Exception: System.MissingMethodException: Cannot create an instance of an interface."

 

have attached the .dll and is there is any other way to create a .net object.

or any way to solve this problem?

Hi @Rajhelboy 

 

You should use a .NET Constructor Node to create an instance.

Unfortunately sir, this will not work as the object is not initialized, i have tried that earlier, for now i have modified the dll to give output for an initialized Barcode Format object.
