      I am getting the following information in the desktop info error log:
      ERROR WMI [error] : Invalid variant type conversion

      The offending query seems to be this:
      WMI=active:1,interval:0,color:FFFFFF,text:Model:,namespace:root\cimv2,query:Win32_ComputerSystem,display:%model%,text-offset:43

      I think the issue is that WMI is returning a string and delphi is trying to convert it to a string a second time. At least that’s what I can gather from google. I’m not sure how I avoid the unnecessary conversion though?

      The query is returning the text I want, so I am tempted to turn off error logging and ignore the issue but I hate leaving errors 🙂

      Thanks
      Brad

      I can’t reproduce that here. Perhaps you can switch on debug and send me the resulting log.

      Glenn any thoughts on the above? I can just disable logging and ignore it but it’d be great not to ignore the problem 🙂

        There’s an error processing a WMI result set. The item in question is not identified. Do you notice any of the wmi items showing empty results? If not it might be an interesting exercise to put every single result property on the display and see what’s there and what isn’t.
