请教下，我写了个监视记事本的键盘Hook程序。在VC6.0中编译运行后弹出DebugError的错误提示。好像是函数调用约定不对，不知道该怎么解决。
另外，程序HOOK功能正常。
我不懂汇编，接触Windows编程也不久。
详细:
The value of ESP was not properly saved across a function call.This is usually a result of
calling a function declared with one calling convention with a function pointer declared
with a different calling convention.
下面附上代码，有两个文件，t.c(exe文件)和fDll.c(Dll文件)，分开编译:
//t.c
#include <windows.h>
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,
       LPSTR pCmdLine,int iShowcmd)
{
 HMODULE hLibrary;
 FARPROC fpSethook,fpUnhook;
 HWND hParent,hChild;
 DWORD dwThread;
 hParent=FindWindow(NULL,"jk.txt - 记事本");
 hChild=FindWindowEx(hParent,NULL,"Edit",NULL);
 dwThread=GetWindowThreadProcessId(hChild,NULL);
 hLibrary=LoadLibrary("fDll.dll");
 fpSethook=GetProcAddress(hLibrary,"Sethook");
 if(dwThread&&hLibrary&&fpSethook)
  MessageBox(NULL,"开始安装Hook","",MB_OK);
 if(fpSethook(hLibrary,dwThread))
  MessageBox(NULL,"函数已返回","",MB_OK);
 MessageBox(NULL,"终于成功啦!","",MB_OK);
 fpUnhook=GetProcAddress(hLibrary,"Unhook");
 if(fpUnhook)MessageBox(NULL,"成功","",MB_OK);
 fpUnhook();
 FreeLibrary(hLibrary);
 MessageBox(NULL,"Start Setup Hook","",MB_OK);
}
//fDll.dll
#include <windows.h>
LRESULT CALLBACK Hookproc(int nCode,WPARAM wParam,LPARAM lParam)
{
 MessageBox(NULL,"哈哈","",MB_OK);
 return (LRESULT)CallNextHookEx(hHook,nCode,wParam,lParam);
}
__declspec(dllexport) BOOL Sethook(HMODULE hLibrary,DWORD dwThread)
{
 hHook=SetWindowsHookEx(WH_KEYBOARD,Hookproc,hLibrary,dwThread);
 if(hHook)
  return TRUE;
 else
  return FALSE;
}
__declspec(dllexport) void Unhook()
{
 UnhookWindowsHookEx(hHook);
}
