Detailed Description of Changes in HALCON Progress (Hotfix)

The changes in HALCON Progress are described with respect to HALCON Progress.


  • On some computers, HALCON could not start after 2021-01-01 and showed the error 2021 (“System clock has been set back”). This problem has been fixed.


  • HDevelop's variable inspection windows did not use the selected 'Values and Parameters' font when opened. This problem has been fixed.
  • If a procedure interface dialog had been added to the docking environment during the previous session, and then this dialog was used in the new session, HDevelop could crash during a restart. This problem has been fixed.
  • On some platforms, the program editor did not have the input focus on startup. This problem has been fixed.

Code Export

  • If an output variable for an operator call was also used in an expression passed as input parameter (e.g., concatenation), the export to C# and VB.net did not work. This problem has been fixed.
