以下是我的程式 Server部份    ==================================================================    //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" TForm1 *Form1; AnsiString CurrentDir; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner)         : TForm(Owner) { } //---------------------------------------------------------------------------    void __fastcall TForm1::Broker_ServerExecute(TIdPeerThread *AThread) {  AnsiString Serverlet_message=AThread->Connection->ReadLn();  //Server一執行所傳回來的訊息,包含執行主機IP與Serverlet的檔名  //例如:140116039126@math  Edit1->Text=Serverlet_message;  ListBox1->Items->Add(Serverlet_message); } //--------------------------------------------------------------------------- void __fastcall TForm1::FormCreate(TObject *Sender) {  char buf[512];  GetCurrentDirectory(512,buf);  CurrentDir=buf;  //Broker Server 設定  Broker_Server->DefaultPort=6666; //port  Broker_Server->Active=True;      //開啟  //End } //---------------------------------------------------------------------------    Client部分 ===================================================================== //---------------------------------------------------------------------------    #include  #pragma hdrstop #include "Unit1.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" TForm1 *Form1; AnsiString IP; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- void __fastcall TForm1::FormCreate(TObject *Sender) { Serverlet_IP->Active=True; IP=Serverlet_IP->LocalIP(); Edit1->Text=IP; Broker_Client->Port=6666; Broker_Client->Host="140.116.39.126"; //連到Service Broker } //--------------------------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) { Broker_Client->Connect(); Broker_Client->WriteLn(IP); } //--------------------------------------------------------------------------- 我的目的是,一但Client程式執行時,會傳本身的IP給Server讓Server知道他的IP,我是用WriteLn與ReadLn做,我在單機上try(127.0.0.1)沒問題,但如果我在家執行Client(浮動,且加裝IP Router),Server在學校執行(固定IP),就會出問題,請問各位高手,這是什麼原因??是不是我的Readln一定得設終止符號才行?? 小弟才疏學淺,問這個笨問題,請多指教 < class="code">
