Help Oblob code stopped working (oo4o)

I was working with 0040 2.3 and upgraded to the version that comes with 8i and some code that previously worked stopped working.

I put in some try catch wrappers and changed a couple of things but I cannot get anything to work.

Previously it was this

if(0 != oDynamicSet.GetFieldValue(_T("WORKBOOK"), lpszCompressedBlob, lBlobLength, &lBytesRead))

but that started throwing exceptions with no error text in them . So I changed this to

OBlob blob;
try
{

    if(0 != oDynamicSet.GetFieldValue(_T("WORKBOOK"), &blob))

        return false;

     bool b;
     b = blob.IsNull();
     b = blob.IsOpen();

this code blows up right when I call the IsNull returning error code 16 #define OERROR_NOTOPEN 16 // attempt to use unopened object

I don't know how I'm supposed to open it other than the getfieldvalue call. This is pretty much the same as the sample code.

Thanks
