Archie, I was testing the Ini parser in v3.6.8 without a PLC online right now. I added the file as you mention, changed the CopyToOutputDirectory property, added those exact lines you wrote to the text file, and set the IniFileName property to TextFile1.txt (name of my text file). I still get the "Undefined message for 0" legend. If I change the file name property to something different the legend would change to "Could not find.." (it gets cut by the frame), so it looks like is being found but now shown. What am I missing?
