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 反之可以使用char *p=_com_util::ConvertBSTRToString(b); 2、VARIANT、_variant_t与COleVariant VARIANT:的结构可以参考头文件...

cannot convert parameter 1 from 'const char [12]' to 'LPCWSTR' Where LPCWSTR maps to a wchar_t pointer, regardless of your build configuration. This problem can be resolved primarily by using solution #2, but in some cases also #1. A lot of the Microsoft provided libraries, such as...

create_string_buffer() 函数已经替换了 c_buffer() 函数(仍然作为别名存在),有如 c_string() 函数以前,只是出现在以前的版本中。想要创建包含unicode字符(对应C类型wchar_t)的可变内存块,使用create_unicode_buffer() 函数。 2.5 调用函数,继续 需要注意的是,printf打印到真实的标准输出,而不是 sys.stdout ,...
