AddHandler will not fire method

General

Hi community ,
i have following problem:

A thread subclass in the run event handle

  mRunning = True
  sharedManager.ChangeSharedResource(true)
  
  Dim SSLSocket As new HTTPSecureSocket
  AddHandler SSLSocket.ReceiveProgress, AddressOf me.ReceiveProgress
  AddHandler SSLSocket.Connected, AddressOf socketconnected


  SSLSocket.requestHeaders.DeleteAllHeaders
  SSLSocket.requestHeaders.AppendHeader("Accept","application/json")
  SSLSocket.requestHeaders.AppendHeader("Content-Type","application/json")
  SSLSocket.requestHeaders.AppendHeader("User-agent","MusicInstructor")
  Dim uri As String = self.getURL(mQuery,mTitle,mArtist,mAnv,mLable,mReleaseTitle,mTrack)
  Dim jsonData As String = SSLSocket.Get(uri,10)
  mJsonData = jsonData
  mRunning= False
  sharedManager.ChangeSharedResource(false)

The HTTPSecureSocket received the data, but the socketconnected method never be fired and no compiler error´s appears.
The socketconnected method look´s like:

socketconnected ( sender as HTTPSecureSocket)

have anyone an idea whats missing
best regards
Martin

i have found the problem by my self.
the problem was the

Dim jsonData As String = SSLSocket.Get(uri,10)

this call is synchronically and never trigger this method .
