[V4RB] Updating Blob Fields in VCursors

[Joerg Pressel]

How could I update a Blob field in a cursor?

I tried:
       cur.BlobField(4).WriteRawData s
       If cur.Update Then
         // O.K.
       End If

Cursor is read and write and field #4 is a VBlob field – but it does 
not work.

Any idea what's wrong?

TIA,

Jörg
