Thanks you Rudi. It work well.

Hi.

How to simply put on label the Hex value of a Bit32 DPE?

VS2013 instead off 2015 solved the problem with wincc_OA scripts. But problem with the dll came again with the new VS project. I translated my functions directly in winncc_Oa scripts to solve issue.

I'm not sure about the compatibility with vs2015. I still have error messages when i want to use wincc_OA scripts. I'll try tomorrow with a VS2013 installation. Thanks Frenck or your help
