These executables are consolidated here for the settings.json file associated with the 'Calc Tools' extension. Harry wrote that extension pre-covid, and we have not yet found the source code. Ionic.zip.dll and NNewtonsoft.Json files are required for CheckBoxControl tool to work properly. Tools are in process of being converted to web-based. As they are, either the settings.json file needs to be updated or shortcuts put into the 'calcext' extension. Dataflow web-based shortcut (Alt+D) code lives in tht calcext extension, written by Joe A. After any update to the settings.json file, each VSC user will need to replace their local copy with the source copy. ** I can't get CalcHelper to Launch without error, seems one of the million associated files can't be found. I've tried moving several other associated files to this folder with no success, so just keeping the STFXPdfDotNET.dll file until I can figure out the other dpendencies
