Visual Basic Syntax

strValue = oXMLHttpRequest.responseStream

C/C++ Syntax

HRESULT get_responseStream(VARIANT* pvarBody);

Parameters

pvarBody [out, retval]
The response entity body as an IStream.

C/C++ Return Values

S_OK
The value returned if successful.

E_PENDING
The value returned if the data is unavailable.

Example

HRESULT hr;
IXMLHttpRequest *pIXMLHttpRequest = NULL;
IStream *pIStream = NULL;
VARIANT varValue;

try
{
   // Create XMLHttpRequest object and initialize pIXMLHttpRequest.
   hr = pIXMLHttpRequest->get_responseStream(&varValue);
   if(SUCCEEDED(hr))
   {
      pIStream = (IStream*)varValue.punkVal;
      if(pIStream)
      {
         pIStream->Release();
         pIStream = NULL;
      }
   }
}
catch(...)
{
   if(pIStream)
      pIStream->Release();
   DisplayErrorToUser();
}
// Release pIXMLHttpRequest when finished with it.

Remarks

Variant. The property is read-only. Represents the response entity body as an IStream. This stream returns the raw undecoded bytes as received directly from the server. Therefore, depending on what the server sent, this may appear as binary-encoded data (UTF-8, UCS-2, UCS-4, Shift_JIS, and so on).
