Delphi Socekt

用Indy组件写了个小聊天室。但好象客户端不能的消息没有发送到服务器。
procedure TForm1.EditMsgKeyPress(Sender: TObject; var Key: Char);
begin
if key = #13 then
begin
if IdTCPClient.Connected = True then
begin
IdTCPClient.WriteLn(EditName.Text+':'+EditMsg.Text+EOL);
EditMsg.Clear;
end;
end;
end;
这个客户端发送消息事件的代码。也不知道是不是服务器没有转发，下面的服务器处理收到消息的代码：
procedure TForm1.IdTCPServerConnect(AThread: TIdPeerThread);
var
Buf: string;
i:integer;
begin
Buf:=AThread.Connection.ReadLn;
if Buf='' then exit;
if Buf[1]=CMD then
begin
//系统命令
Buf:=Copy(Buf,2,Length(Buf)-1);
AThread.Connection.WriteLn('Welcome:'+Buf+EOL);
end else begin
//聊天信息
list:=IdTCPServer.Threads.LockList;
try
for i:=0 to list.Count-1 do
try
AThread.Connection.WriteLn(Buf);
except
AThread.Stop;
end;
finally
IdTCPServer.Threads.UnlockList;
end;
end;
end;
请高手帮忙看下是怎么回事，万分感谢！

昨天有点头晕了，几句话都说不清楚了。
总归就是客户端没有正常显示收到的消息。补充一个客户端处理收到消息的事件：
procedure TForm1.IdTCPClientConnected(Sender: TObject);
var
Lin:string;
begin
Lin:=IdTCPClient.ReadLn();
if Lin='' then exit;
ListBoxMsg.Items.Add(Lin);
end;

IdTCPServerConnect
改用IdTCPServerExecute事件

好像是事件写错地方了 客户端的,你看下. unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, ImgList, StdCtrls, Buttons, ComCtrls, ScktComp, ToolWin, ExtCtrls; const SocketHost = '172.20.100.22'; //服务器端地址 type TfrmClientMain = class(TForm) ControlBar1: TControlBar; ClientSocket: TClientSocket; Edit1: TEdit; Memo1: TMemo; StatusBar: TStatusBar; btnSend: TBitBtn; ImageList1: TImageList; tbConnected: TButton; tbSend: TButton; tbclose: TButton; tbDisconnected: TButton; procedure tbConnectedClick(Sender: TObject); procedure tbDisconnectedClick(Sender: TObject); procedure ClientSocketRead(Sender: TObject; Socket: TCustomWinSocket); procedure tbSendClick(Sender: TObject); procedure tbCloseClick(Sender: TObject); procedure FormShow(Sender: TObject); procedure ClientSocketConnect(Sender: TObject; Socket: TCustomWinSocket); procedure ClientSocketConnecting(Sender: TObject; Socket: TCustomWinSocket); procedure ClientSocketDisconnect(Sender: TObject; Socket: TCustomWinSocket); procedure FormClose(Sender: TObject; var Action: TCloseAction); procedure ClientSocketError(Sender: TObject; Socket: TCustomWinSocket; ErrorEvent: TErrorEvent; var ErrorCode: Integer); private { Private declarations } public { Public declarations } end; var frmClientMain: TfrmClientMain; implementation {$R *.dfm} //打开套接字连接 procedure TfrmClientMain.tbConnectedClick(Sender: TObject); begin ClientSocket.Open ; end; //关闭套接字连接 procedure TfrmClientMain.tbDisconnectedClick(Sender: TObject); begin ClientSocket.Close; end; //接受服务器端的回复 procedure TfrmClientMain.ClientSocketRead(Sender: TObject; Socket: TCustomWinSocket); begin Memo1.Lines.Add(Socket.ReceiveText); end; //发送信息到服务器端 procedure TfrmClientMain.tbSendClick(Sender: TObject); begin ClientSocket.Socket.SendText(Edit1.Text); end; procedure TfrmClientMain.tbCloseClick(Sender: TObject); begin Close; end; //设置要连接的服务器端地址 procedure TfrmClientMain.FormShow(Sender: TObject); begin ClientSocket.Host := SocketHost; end; //已经连接到服务器端 procedure TfrmClientMain.ClientSocketConnect(Sender: TObject; Socket: TCustomWinSocket); begin tbSend.Enabled := True; tbDisconnected.Enabled :=True; btnSend.Enabled := True; StatusBar.Panels[0].Text := '已经连接到 '+ Socket.RemoteHost ; end; //正在连接到服务器端 procedure TfrmClientMain.ClientSocketConnecting(Sender: TObject; Socket: TCustomWinSocket); begin StatusBar.Panels[0].Text := '正在连接到服务器...
