I am having major difficulty in getting CreateBlobStream to work properly
with Builder 6.  I am using the code below and I can get it to compile, but
the program crashes with a message like "Invalid Variant Operation".  I am
connected to a MS SQL database and the field that I am trying to access is
defined as a VarByte with a size of 8000.  The help in BCB6 is not correct
for ADO blobs and I cannot find any other help on the web.  I am stuck at
this point.  Please help if there are any sugestions.

    int MemSize;
    char *Buffer;
    TADOBlobStream *Stream;

//Crashes on this line.  I have tried many variations including
"CreateBlobStream"with no success.
    Stream = new TADOBlobStream((TBlobField
*)adoTraceDetailsDataSet->FieldByName("TraceArray") , bmRead);
