Legacy ddcBar Patch File

ddcBar version 19.3.19 r2 will be the last full installer for the legacy ddcBar which supports Windows XP and Visio 2007. Any updates to the core ddcBarLib.vsl file will be posted here as a patch file. To install a patch file you must have installed the last available version of 19.3.19 (r1 or r2). Download this file, unzip and place the ddcBarLib.vsl file in the ddcBar installation folder. For typical installations this folder would be “c:\alerton\ddctools\ddcbar”. Your installation may be different.

Updates and issue fixed with the patch file are:

  • DDC Simulator: Comparator was not calculating the output result correctly when the dead-bands were set to zero.
  • VLX Configuration dialog: Updated to support more “known” GC Builder Excel workbook versions.
  • DDC Simulator: Fixed issue in REDS device where only the 1st branch point was being recognized.
  • Load Drawing: Fixed issue where loading a drawing from the command line would not use the correct database provider.
  • DDC Compare: Fixed issue where the Data Writer would show up as Unknown device with an error. Also corrected the device display name.
