Barcode Bug in CVB 7.1.2

I am reading 1 dimensional Barcodes with the Barcode OCX or Barcode DLL in CVB. As I know the orientation I want to use the FENCE and LADDER parameters to speed up reading. In CVB 7.1.1 this worked well, in 7.1.2 Barcode seems unable to read with the above parameters and I have to use the OMNI or BOTH setting. Why?

Mixing Use of the Display DLL and the Display OCX

The Common Vision Blox Display OCX als well as the Common Vision Blox Display DLL provide functions for displaying textual labels on a display. With the OCX methods it is no problem to position a label on a Display OCX, but calling the corresponding functions of the Display DLL on the Display OCX yields nothing. The same effect can be seen with other functions (e. g. Overlay management functions). What is the reason for this behaviour?
