C++/(MFC)CString to BSTR . . . . 15회 일치

     === 'CString' to 'BSTR': ===
     BSTR bstr = str.AllocSysString();
     If you pass the 'BSTR' to some OLE function, this will normally free the 'BSTR' memory when done with it.
     If you use the 'BSTR' by yourself, dont forget to call '::SysFreeString()' when you're done with it.
     ::SysFreeString(bstr);
     === 'BSTR' to 'CString': ===
     You will mostly need this when you have some OLE function that returns a 'BSTR'. Such an OLE Function will basically do something like this:
     HRESULT SomeOLEFunction(BSTR& bstr)
      bstr = ::SysAllocString(L"Hello");
     Use a temporary variable of the type '_bstr_t' to wrap the 'BSTR'. This way you handle both the 208 and make sure that you have no memory leak:
     BSTR bstr;
     SomeOLEFunction(bstr);
     _bstr_t tmp(bstr, FALSE); //wrap the BSTR
     // when tmp goes out of scope it will free the BSTRs memory
     What is this BSTR thing, and how does it differ from WCHAR* ? Here is Eric's Complete Guide To BSTR Semantics.
