這是上網找人家的source code，可是complier過不了，請大大幫我debug一下

主要是錯在xUDP.SendBuffer(JpgBlock[tag],xstrm.Size 3);
錯誤訊息：
[Pascal Error] Unit1.pas(183): E2250 There is no overloaded version of 'SendBuffer' that can be called with these arguments

它不是跟你說得很清楚了嗎？
SendBuffer 的參數呼叫法錯了。不能用這樣的參數格式。
看一下 xUDP 的宣告是怎樣吧。

您好，謝謝您的回答，因為我是初學，所以程式碼還看不怎麼懂，目前第一步只希望compiler能過，
希望各位大大能夠幫我改進一下語法，謝謝。
開發平台是Borland Developer Studio 2006
這是SendBuffer的參數
Procedure SendBuffer(AHost : String ; const APort : Integer ; const ABuffer : Tbytes);
Procedure SendBuffer(const ABuffer : Tbytes);

我試過xUDP.SendBuffer(xUDP.Host,xUDP.Port,JpgBlock[tag]);
也是出現一樣的錯誤

如果是程式碼不足，我可以在將其他部份在貼上，謝謝

以上為原始的主機程式碼

procedure SendBuffer(
AHost: string;
const APort: Integer;
const ABuffer: TIdBytes
); override; overload;
TIdUDPClient.SendBuffer 的宣告如上
前兩個參數要傳入 remote 的 Host 與 Port

我試過xUDP.SendBuffer(xUDP.Host,xUDP.Port,JpgBlock[tag]);
或xUDP.SendBuffer(xUDP.Host,xUDP.Port,xstrm.Size);
或xUDP.SendBuffer(xUDP.Host,xUDP.Port,JpgBlock[tag],xstrm.Size);
也是出現一樣的錯誤

真的是初學，只能亂試，希望高手能夠給予指點
