实际上bstr很像delphi里面的string，平时只是指向pchar或pwchar，但是在pchar和pwchar的前面却有长度信息，以下是一段来自网络的解释： BSTR并不是WCHAR*，BSTR...所以，你可以将BSTR当作WCHAR*用，但是不能将WCHAR*当作BSTR用！...要使用(_bstr_t)进行类型转换，必须引用以下库： #include #pragma comment(lib,"comsuppw.lib") 或 comsuppwd.lib...(d一般代表debug版本) HRESULT hres = (*pSvc)->ExecQuery((_bstr_t)_T("WQL"), szQuery, WBEM_FLAG_FORWARD_ONLY
例如： CComBSTR bstr1; bstr1 = “Bye”; // 直接赋值 OLECHAR* str = OLESTR(”ta ta”); // 长度为5的宽字符 CComBSTR bstr2...”)); CComBSTR bstr4(5, “Hello World”); CComBSTR bstr5(OLESTR(”Hey there”)); CComBSTR bstr6(”Hey there...”); CComBSTR bstr7(bstr6); // 构造时复制，内容为”Hey there” _bstr_t是是C++对BSTR的封装，它的构造和析构函数分别调用SysAllocString和SysFreeString...例如： BSTR bstrText = CComBSTR(”This is a test”); 或 CComBSTR bstr(”This is a test”); BSTR bstrText = bstr.m_str...、_bstr_t与CComBSTR CComBSTR、_bstr_t是对BSTR的封装,BSTR是指向字符串的32位指针。

BSTR COM中规定了一种通用的字符串类型BSTR，查看BSTR的定义如下： typedef /* [wire_marshal] */ OLECHAR *BSTR; typedef WCHAR OLECHAR...; 从上面的定义上不难看出BSTR其实就是一个WCHAR ,也就是一个指向宽字符的指针。...在BSTR类型中，定义了两个函数SysAllocString(),和SysFreeString()用来分配和释放一个BSTR的内存空间。...在这总结一下他们之间的相互转化： char*----->BSTR: _com_util::ConvertStringToBSTR WCHAR---->BSTR:可以直接用 = 进行赋值，也可以使用SysAllocString...BSTR---->WCHAR:一般是直接使用等号即可，但是在WCHAR使用完之前不能释放，所以一般都是赋值给一个CString BSTR---->char:_com_util::ConvertBSTRToString
