Hello Cyril. Thanks for your help.
I'm using LabView Vers. 6.0.2.
I've tried to build a more simplier application, and the building works fine, both exe and tlb files are generated.
Do you know any pb for activeX server building related to application "complexity"?
Are there any "components" (vi, ctl,dll...) which are not compatible with activeX server building?
😉
