  Hello! Might be little off topic, but I don't really know where else to ask. I'll appriciate any help...

• Visual C# Delegates Problem - calling method more time then expected

  Hi all, I am having very strange problem. I am using delgate to call one of the method in the class. The problem is eveytime the event occurs it increasing the call value by one.

SocketEventHandler (site_SocketChanged); // where site is the object of type Site void site_SocketChanged(AC. Site site) { object [] param = new object [] ...Show All
