VB.NET Event addressof -

i set callback raised in class different class:

public class camerawindow         inherits system.windows.forms.control         private m_camera camera = nothing          ' camera property         <browsable(false)> _         public property camera() camera                             return m_camera             end             set(value camera)                 ' lock                 monitor.enter(me)                  ' detach event                 if m_camera isnot nothing                     m_camera.newframe -= new eventhandler(addressof camera_newframe)                     timer.[stop]()                 end if                  m_camera = value                 needsizeupdate = true                 firstframe = true                 flash = 0                  ' atach event                 if m_camera isnot nothing                     m_camera.newframe += new eventhandler(addressof camera_newframe)                     timer.start()                 end if                  ' unlock                 monitor.[exit](me)             end set         end property          ' on new frame ready         private sub camera_newframe(sender object, e system.eventargs)             invalidate()         end sub 

the event defined in

  public class camera          public event newframe eventhandler 

but vb.net not way attach , detach events. can tell me how correctly?

thank help!

that looks if you're using c#. in vb.net use addhandler statement:

addhandler m_camera.newframe, addressof camera_newframe 

to remove handler use removehandler

removehandler m_camera.newframe, addressof camera_newframe 

however, if event handler in different class need public:

public sub camera_newframe(sender object, e system.eventargs)     invalidate() end sub 

and need instance:

addhandler camera.newframe, addressof m_camera.camera_newframe
