Good morning forum, 
i'm new to zenon Integration.
I would like to export all alarms from my zenon with an external C# program, i admit that i already search in the forum for a solution.

This is my code:

zenonApp = new zenOn.Application();
zenonApp = GetObj(1, "zenOn.Application");
projects = (zenOn.Projects)zenonApp.Projects();
prj = projects.Item(0);
alarm = prj.Alarm();
al_items = alarm.AlarmItems("*");

al_items.Count always return 0, why? 
Am i doing something wrong ?
Or am i searching in the wrong method?

Thanks in advance
