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

If i move IsOpen up above it returns false.

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.

Anyone know what I'm doing or oracle is doing that is wrong. Like I said this code worked fine before the upgrade.

Thanks
