Answer 1

Your sql should be this:

UPDATE Invenotry
SET B = @B
WHERE A = @A

You can also try the full version of a parameter constructor:

SqlParamter param = new SqlParameter("@B", SqlDbType.VarBinary, 1728, ParameterDirection.Input, 
     // we have these parameters but they are ignored for input types
     false, 0, 0, null, DataRowVersion.Current, 
     // the data
     to_store);

cmd.Parameters.Add(param);
