How can I load on the TComboBox component one colum of a TDBGrid (I load one Table1) that I create from a DataBase (Access 97).
I only could load the first line of my Table1 with this:

cant := Form1.Table1.RecordCount;
  for  i := 0 to cant do
    Form3.List.Items.Insert(i, Form1.Table1);

I need to load each line of one colum.  Thanks.

Hello

  change ur code as following ,you are adding only the first record, so you need to move to the next one


cant := Form1.Table1.RecordCount -1;
 for  i := 0 to cant do
  begin
   Form3.List.Items.Insert(i, Form1.Table1);
   Form1.Table1.Next;
  end

Hi matuf,

something like this:

Table1.DisableControls;
Table1.First;
while not Table1.EOF do
begin
  ListBox1.Items.Add(Table1.Fields[3].AsString);
  Table1.Next;
end;
Table1.EnableControls;

recordcount is not allways properly set,
depending on the database

better would be
table1.first;
while not table1.eof do
begin
  Form3.List.Items.add(table1.fieldbyname('fieldwhateverneeded').asstring;
  table1.next;
end;

meikl ;-)
