Steve Gill 02.09.2006 09:15:00 Registered user	I would like to display the number of current connections in the server's main window.  I have tried both the TotalConnectionCount and TotalServerConnectionCount methods in the Connect and Disconnect events.  They seem to show the correct count when clients connect, but the counts seem to be one too many when the clients disconnect. As each client connects the count goes up.  However, the count seems do be one step behind on disconnects.  When there is only 1 client connected it shows 2 connections.  And when no clients are connected it shows 1 connection. procedure TfrmMain.HttpServerConnect(Sender: TRtcConnection); begin    with Sender as TRtcConnection do    begin       edtConnections.IntValue := TotalConnectionCount;    end; end; procedure TfrmMain.HttpServerDisconnect(Sender: TRtcConnection); begin    with Sender as TRtcConnection do    begin       edtConnections.IntValue := TotalConnectionCount;    end; end; Is there anything else I need to do? Regards, SteveG

Btw .. there's no need to cast Sender to TRtcConnection, since it already is TRtcConnection. You should only cast it to TRtcDataServer if you need more infromation.  Also, if your Server is MultiThreaded, you need to Sync() your events before accessing the GUI: procedure TfrmMain.HttpServerConnect(Sender: TRtcConnection); begin   if not Sender.inMainThread then     Sender.Sync(HttpServerConnect)   else     edtConnections.IntValue := Sender.TotalConnectionCount; end; procedure TfrmMain.HttpServerDisconnect(Sender: TRtcConnection); begin   if not Sender.inMainThread then     Sender.Sync(HttpServerDisconnect)   else     edtConnections.IntValue := Sender.TotalConnectionCount-1; end; Best Regards, Danijel Tkalcec

ISOFT, INC. 24.01.2007 16:26:38 Registered user	The above code in Delphi looks like this in BCB void __fastcall TForm1::RtcHttpServer1Connect(TRtcConnection *Sender) {         if (Sender->inMainThread() == false)         {                 Sender->Sync(&RtcHttpServer1Connect);         }         else         {                 StatusBar1->SimpleText = "Total connections: " + AnsiString(Sender->TotalConnectionCount());         } } void __fastcall TForm1::RtcHttpServer1Disconnect(TRtcConnection *Sender) {         if (Sender->inMainThread() == false)         {                 Sender->Sync(&RtcHttpServer1Connect);         }         else         {                 StatusBar1->SimpleText = "Total connections: " + AnsiString(Sender->TotalConnectionCount()-1);         } } This is my first attempt at this - so I may not have done it exactly right.
