HI
I am using labview to read ECU data from INCA software .INCA providing COMTOOL API(incacom.dll). I am using ACTIVEX for communication between INCA & Labview. My problem is If I have used single activex class object I am able to read Inca version, getting the database path etc. If I have used two activex class in same vi (one to open Inca & other one is to read the folder structure) I am not getting output.I have attached snapshot for referance

There is no general issue with using multiple ActiveX classes in the save VI. This sounds more like an issue with the specific ActiveX component that you are using. I would suggest contacting the component vendor with this question.

As you are only using references one after the other, you could try closing references before opening the other.

It wasnt in the first two images you posted, or I couldnt see it anyway! That was the only reason.
Did you try the database block on its own, just to confirm that it is working?

Do you want to share you solution?
I'm in the same situation. Can read a value from INCA but not a table. Also would like to write value to a table further on.
