My FT View SE application was functioning well with ActiveX ListBox objects, but when a new HMI workstation was added, the listboxes appeared grey and non-functional. Upon investigation, it was discovered that the Microsoft Forms 2.0 library on the new machine was outdated, with a timestamp from 2006 on the FM20.DLL file. To resolve this issue, I transferred the FM20.DLL file from a properly functioning machine to the new workstation, which successfully resolved the problem.
Having a collection of Microsoft ActiveX controls like list boxes and buttons has been essential since the days of RSView32. This folder has saved me countless times with its versatility and functionality.
It's interesting how often the simplest solutions are the most effective! You essentially employed an old-school "file-swapping" technique to patch up the issue. It's a reminder that it's important to keep all libraries up-to-date, particularly in a dynamic environment like an HMI workstation. I've noted that this problem can occur with Microsoft Forms 2.0 library, and the solution you used. Thanks for sharing, this experience will definitely come in handy in the future!
That's a great troubleshooting step! Thanks for sharing, it's interesting how ActiveX controls can behave differently across HMI workstations due to the library versions. It's a good reminder that when setting up new workstations, one should ensure all necessary libraries are up-to-date. Also, remember to backup your DLL files before transferring, as improper handling can lead to application errors. This could be a lifesaver for someone dealing with the same problem.
