Previously I was looping thru TADOQuery object. I changed the code which now loops thru TADOQuery.recordset But now I have problem while passing the field into existing procedure

//// ----- Previous Code (which works fine)

Procedure ReadRecord(Fld : TField)

qr := TADOQuery.create(nil);
qr.sql.text := 'select * from table1'

with qr do
  while not eof
  begin
     ReadRecord(qr.fields[0]) ;
     Next ;
  end ;

//// ----- Latest Code

Procedure ReadRecord(Fld : TField)

qr := TADOQuery.create(nil);
qr.sql.text := 'select * from table1'

rs := qr.recordset ; {where as rs is type _Recordset}
with rs do
  while not eof
  begin
     ReadRecord(rs.fields[0]) ; //compile error here
     MoveNext ;
  end ;

I get compile error in readrecord line. I tried to typecast as Tfield but I got access violation. Pls help me to solve this problem

Thx in advance.

The problem is that the types are different. ADO does not know TField.

Try the following:
First put ADOInt in the uses clause. Second change the parameter type of ReadRecord from

Procedure ReadRecord(Fld : TField)

to

Procedure ReadRecord(Fld : Field)


But I don't think this is what you want.
