简单的程序编译不过去，

[gunboat]

利用向导产生dll文件（Mfc dll),选择mfc extension dll,然后在project中增加一个.h文件，在.cpp文件中包含增加的文件，编译无法通过。
增加的.h文件如下
#ifndef _KEYDLL_H
#define _KEYDLL_H
//文件名称ActiveKey.h
class AFX_EXT_CLASS CKeyHook : public CObject
//class AFX_EXT_CLASS CKeyHook:public CObject
{
public:
CKeyHook();
~CKeyHook();
HHOOK Start(); //安装钩子
BOOL Stop(); //卸载钩子

}

#endif


.cpp文件如下：
#include "stdafx.h"
#include "ActiveKey.h"
#include <afxdllx.h>


#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif


static AFX_EXTENSION_MODULE ActiveKey1DLL = { NULL, NULL };

CKeyHook::CKeyHook(){}



extern "C" int APIENTRY
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
// Remove this if you use lpReserved
UNREFERENCED_PARAMETER(lpReserved);

if (dwReason == DLL_PROCESS_ATTACH)
{
TRACE0("ACTIVEKEY1.DLL Initializing!\n");

// Extension DLL one-time initialization
if (!AfxInitExtensionModule(ActiveKey1DLL, hInstance))
return 0;

// Insert this DLL into the resource chain
// NOTE: If this Extension DLL is being implicitly linked to by
// an MFC Regular DLL (such as an ActiveX Control)
// instead of an MFC application, then you will want to
// remove this line from DllMain and put it in a separate
// function exported from this Extension DLL. The Regular DLL
// that uses this Extension DLL should then explicitly call that
// function to initialize this Extension DLL. Otherwise,
// the CDynLinkLibrary object will not be attached to the
// Regular DLL's resource chain, and serious problems will
// result.

new CDynLinkLibrary(ActiveKey1DLL);
}
else if (dwReason == DLL_PROCESS_DETACH)
{
TRACE0("ACTIVEKEY1.DLL Terminating!\n");
// Terminate the library before destructors are called
AfxTermExtensionModule(ActiveKey1DLL);
}
return 1; // ok
}



提示的错误如下：
c:\program files\microsoft visual studio\vc98\mfc\include\afxdllx.h(35) : error C2143: syntax error : missing ';' before 'string'
c:\program files\microsoft visual studio\vc98\mfc\include\afxdllx.h(35) : fatal error C1004: unexpected end of file found
Error executing cl.exe.

~CKeyHook();
HHOOK Start(); //安装钩子

}; //这里没有 ；

我怎么给你分呀，我没用过这东西
