CComBSTR、_bstr_t是对BSTR的封装,BSTR是指向字符串的32位指针。 char *转换到BSTR可以这样:BSTR b=_com_util::ConvertStringToBSTR("数据");//使用前需要加上头文件comutil.h(有时还需头文件comdef.h) 反之可以使用char *p=_com_util::ConvertBSTRToString(b); 六、VARIANT 、_variant_t 与 COleVariant...

如果一个 Win32 API 期望的 PCWSTR (或 LPCWSTR 在旧术语),那就是,const 的 wchar_t * NUL 终止的 C 样式输入的字符串参数,只需调用 std::wstring::c_str 方法将是很好。事实上,此方法返回只读的 NUL 终止的 C 样式字符串的指针。 例如,若要设置窗口的标题栏的文本或使用存储在 std::wstring ...
