unit UMain;

interface

uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
Db, DBTables, StdCtrls, Grids, DBGrids,Excel97,Comctrls,OleCtnrs,ComObj;

type
TForm1 = class(TForm)
DBGrid1: TDBGrid;
Button1: TButton;
Button2: TButton;
DataSource1: TDataSource;
Table1: TTable;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure FormClose(Sender: TObject; var Action: TCloseAction);
private
{ Private declarations }
public
XlsApp,XlsSheet,XlsWBk : Variant;
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
var
I,J : integer;
begin
if VarIsEmpty(XlsApp) then
XlsApp := CreateOleObject('Excel.Application');

XLsApp.Workbooks.Add;
XlsSheet := XLsApp.Worksheets['Sheet1'];

for I := 0 to Table1.Fields.Count - 1 do
begin
XlsSheet.Cells[3,I + 1] := dbgrid1.Columns[I].Title.Caption;
end;

Table1.first;
for J := 0 to Table1.RecordCount - 1 do
begin
for I := 0 to Table1.Fields.Count - 1 do
begin
XlsSheet.Cells[J + 4,I + 1] := Table1.Fields[I].AsString;
end;
Table1.Next;
end;

XlsApp.Visible := true;
end;

procedure TForm1.Button2Click(Sender: TObject);
var
I,J : integer;
TxtFile : TextFile;
TmpString : String;
begin
try
if VarIsEmpty(XlsApp) then
XlsApp := CreateOleObject('Excel.Application');
XlsSheet := XlsApp.workbooks.open('c:\my documents\book3.xls');

AssignFile(TxtFile,'C:\My Documents\Test.txt');
Rewrite(TxtFile);
try
for I := 3 to 21 do
begin
TmpString := '';
for J := 1 to 5 do
begin
TmpString := TmpString + XlsSheet.ActiveSheet.Cells[I,J].Text + '|';
end;
Writeln(TxtFile,Tmpstring);
end;
finally
CloseFile(TxtFile);
end;
