Thanks for bringing up old memories. I'm glad I don't suffer from PTSD over those. <smile>
Yet, I still deal with DLL issues. Older versions of the software I maintain has VFP 9 SP1 and a COM DLL. Occasional a customer will get some other VFP product installed. That other product only installs the VFP 9 SP2 HF 3 dlls they need. Meaning, they don't ship the VFP9T.DLL. Suddenly functionality of my program stops working. Since this is done in a separate thread (Thank you Christof for the DMUTL.DLL), no crashing error happens in the program. It happens often enough I wrote a CMD file to search the C: drive for all instances of VFP9*.DLL, display the full path of it and the version. Later I wrote a .NET Framework WPF app that searches the PATH for VFP9*.DLL files, and gives the tech the ability to overwrite the offending problem DLL. Sometimes it suggests they should delete the file. For those sometimes clever people that think the VFP 9 files are missing and they download RTM and copy them in to the program directory. Oh to have knowledge and not know you don't have enough of the picture to make a good decision. The bane of software design. I live in both it seems.
