I have a POS application. I am trying to format my text before I print it.
I need to add Store Name, address, & phone number,
Date & Time, - as well as some formating of the receipt items. I also need to add two types of taxes (GST, PST)



ps. If Shane Holmes is out there, i'd appreciate his help, since he knows all about the POS

Hi George, Its added and I have emailed you the code.

Modified the following

procedure TfrmMainPOS.actPrintExecute(Sender: TObject);
var
 I: Integer;
begin
 with frmPrint.memPrint.Lines do
  begin
   Add(StoreName);
   Add(StoreAddress);
   Add(StoreCity + ', ' + StoreProvince + '  ' + StorePostal);
   Add(StorePhone);
   Add('');
   Add(DateTimeToSTr(Now));
   Add('');
   for I:= 0 to lvwReceipt.Items.COunt - 1 do
    Add( lvwReceipt.Items[I].SubItems[0] + '  ' +
         lvwReceipt.Items[I].Caption + '  ' +
         lvwReceipt.Items[I].SubItems[1] + '  ' +
         lvwReceipt.Items[I].SubItems[2]);
   Add('');
   Add('Total Items = ' + sttTotalQty.Caption);
   Add('Total Cost = ' + sttTotalCost.Caption);
   Add('Total Tax = ' + sttTotalTax.Caption);
   Add('Grand Total = ' + sttGrandTotal.Caption);
  end;
 if frmPrint.ShowModal = mrOK then
 begin
  if DefaultPrinter <> '' then
   PrintMemo(frmPrint.memPrint, False, False);
 end;
end;

procedure WriteRegistry;
var
 Reg: TRegistry;
begin
  Reg := TRegistry.Create;
  try
    Reg.RootKey := HKEY_CURRENT_USER;
    if Reg.OpenKey('\Software\POS\', True) then
    begin
     Reg.WriteFloat('GST', GST);
     Reg.WriteFloat('PST', PST);
     Reg.WriteString('Store Name', StoreName);
     Reg.WriteString('Store Address', StoreAddress);
     Reg.WriteString('Store City', StoreCity);
     Reg.WriteString('Store State', StoreProvince);
     Reg.WriteString('Store Postal', StorePostal);
     Reg.WriteString('Store Phone', StorePhone);
     Reg.CloseKey;
    end;
  finally
    Reg.Free;
  end;
end;

procedure ReadRegistry;
var
 Reg: TRegistry;
begin
  Reg := TRegistry.Create;
  try
    Reg.RootKey := HKEY_CURRENT_USER;
    if Reg.OpenKey('\Software\POS\', True) then
    begin
    if Reg.ValueExists('GST') then
     GST:= Reg.ReadFloat('GST')
    else
     GST:= 0.08;
    if Reg.ValueExists('PST') then
     PST:= Reg.ReadFloat('PST')
    else
     PST:= 0.07;
    if Reg.ValueExists('Store Name') then
     StoreName:= Reg.ReadString('Store Name')
    else
     StoreName:= 'Acme Store';
    if Reg.ValueExists('Store Address') then
     StoreAddress:= Reg.ReadString('Store Address')
    else
     StoreAddress:= '111 Anywhere';
    if Reg.ValueExists('Store City') then
     StoreCity:= Reg.ReadString('Store City')
    else
     StoreCity:= 'Toronto';
    if Reg.ValueExists('Store Provice') then
     StoreProvince:= Reg.ReadString('Store Provice')
