获取网页源代码的最简单办法，就是利用 WinInet 单元中的函数：
Code
uses WinInet;
function GetWebPage(const Url: string):string;
var
Session,
HttpFile:HINTERNET;
szSizeBuffer:Pointer;
dwLengthSizeBuffer:DWord;
dwReserved:DWord;
dwFileSize:DWord;
dwBytesRead:DWord;
Contents:PChar;
begin
Session:=InternetOpen(\'\',0,niL,niL,0);
HttpFile:=InternetOpenUrl(Session,PChar(Url),niL,0,0,0);
dwLengthSizeBuffer:=1024;
HttpQueryInfo(HttpFile,5,szSizeBuffer,dwLengthSizeBuffer,dwReserved);
GetMem(Contents,dwFileSize);
InternetReadFile(HttpFile,Contents,dwFileSize,dwBytesRead);
InternetCloseHandle(HttpFile);
InternetCloseHandle(Session);
Result:=StrPas(Contents);
FreeMem(Contents);
end;
使用时，直接把收到的源代码显示出来：
Memo1.Text := GetWebPage(\'http://www.delphibbs.com/delphibbs/listq.asp\');
