CComBSTR::m_str

  • Статья

BSTR m_str;

Remarks

Contains the BSTR associated with the CComBSTR object.

Example

CComBSTR GuidToBSTR(REFGUID guid)
{
   // 39 - length of string representation of GUID + 1
   CComBSTR b(39, L"");

   // convert GUID to BSTR
   // m_str member of CComBSTR is of type BSTR. When BSTR param
   // is required, pass the m_str member explicitly or use implicit
   // BSTR cast operator.
   int nRet = StringFromGUID2(guid, b.m_str, 39);

   // above equivalent to:
   // int nRet = StringFromGUID2(guid, b, 39);
   // implicit BSTR cast operator used for 2nd param

   _ASSERTE(nRet);
   return b;
}
