内容：DllRegisterServer调用时,"CLSID_SafeItem"是什么，又在哪里定义的呢？STDAPI DllRegisterServer(void)
{

    if (FAILED(hr))
        return hr;    return NOERROR;
}error C2065: 'CLSID_SafeItem' : undeclared identifier

还是我自己来解决吧！在XXXcontrol.cpp文件中添加下面的东西，就能搞定了！要包括两个文件
#include "comcat.h"
#include "Objsafe.h"// 本控件的CLSID,注册表用
const GUID CDECL CLSID_SafeItem ={ 0x7AE7497B, 0xCAD8, 0x4E66,
                      { 0xA5,0x8B,0xDD,0xE9,0xBC,0xAF,0x6B,0x61 } };
// 版本控制
const WORD _wVerMajor = 1;
// 次版本号
const WORD _wVerMinor = 0;
