以下是我学习MSDN中的文章。总结出适合在C++Builder下创建WebServer的例子：
其中使用ADSI的一些接口，注意要将Activeds.Lib添加入工程，
还要包含以下几个头文件。
比较简单，希望能抛砖引玉。

file://---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"

file://---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
#include "iads.h"
#include "adssts.h"
#include "Adshlp.h"


TForm1 *Form1;

__fastcall TForm1::TForm1(TComponent* Owner)
        : TForm(Owner)
{
}



file://几个参数：ip：ip地址字符串，domain:域名(www.youname.com),DiskPath:虚拟目录路径（C:\wwwroot)
BOOL CreateWebServer(String ip,String domain,String DiskPath)
{
IADsContainer *pCont=NULL;
IADs* pAds=NULL;
IADs* pVrAds=NULL;
IADsServiceOperations *pSrvOp;
IDispatch *pDisp = NULL;
IDispatch *pVrDisp = NULL;
AnsiString WNumer=IntToStr(random(1000)); //取一个随机数建立站点
String newBindings=ip+":80:"+domain;

/* 获得WebServer */
if(ADsGetObject(L"IIS://localhost/w3svc",IID_IADsContainer,(void**)&pCont)==S_OK)
{   //创建站点
  if(pCont->Create(L"IIsWebServer",(wchar_t*)WideString(WNumer),&pDisp)==S_OK)
    {
       pDisp->QueryInterface(IID_IADs, (void**)&pAds);
       pDisp->QueryInterface(IID_IADsServiceOperations, (void**)&pSrvOp);
       pAds->Put(L"ServerSize",Variant(int(1)));
       pAds->Put(L"ServerComment",Variant(String("xiwei")));//服务器注释，没太多用处，xiwei我的名字
       pAds->Put(L"ServerBindings",Variant(String(newBindings)));
       pAds->SetInfo();

    file://创建主目录
    
   pCont->GetObject(L"IIsWebServer",(wchar_t*)WideString(WNumer),&pDisp);//得到刚才创建地网站
   if(pDisp->QueryInterface(IID_IADsContainer,(void**)&pCont)==S_OK)
   {
     if(pCont->Create(L"IIsWebVirtualDir",L"Root",&pVrDisp)==S_OK)
       {
         pVrDisp->QueryInterface(IID_IADs, (void**)&pVrAds);
         pVrAds->Put(L"AccessRead",Variant(BOOL("True")));
         pVrAds->Put(L"AccessWrite",Variant(BOOL("True")));
         pVrAds->Put(L"AccessScript",Variant(BOOL("True")));
         pVrAds->Put(L"EnableDirBrowsing",Variant(BOOL("True")));
         pVrAds->Put(L"Path",Variant(String(DiskPath)));
         pVrAds->Put(L"AppRoot",Variant(String(DiskPath)));
         pVrAds->SetInfo();
         pVrAds->Release();
         pAds->Release();
         pCont->Release();
       }
     file://启动新建的WebServer
    pSrvOp->Start();
    pSrvOp->Release();
    }
   }
}

}
void __fastcall TForm1::Button2Click(TObject *Sender)
{
CreateWebServer(Edit1->Text,"www.cccaaa.com",Edit2->Text);
}

以上内容缺少错误处理，诸如ip地址已被占用等，我认为技术这东西用不着保守，没等生利息呢，已经贬值了。
哈哈，希望各位给以指正！我的Email：proton@yeah.net
