一个文件重复生成的小工具[附源码和可执行文件]

最近，因为项目的需要，我用Delphi开发了一个小的程序。程序的功能就是选择一个文件，而后可以指定复制多少个相同的文件，用这些复制的文件做并发上传文件用。下面附源码和可执行文件。

源码如下：

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, SUIButton, Buttons, StdCtrls, ExtCtrls, SUIForm, ComCtrls;

type
  TForm1 = class(TForm)
    suiForm1: TsuiForm;
    lbl1: TLabel;
    edt1: TEdit;
    btn1: TSpeedButton;
    lbl2: TLabel;
    edt2: TEdit;
    btn2: TsuiButton;
    btn3: TsuiButton;
    dlgOpen1: TOpenDialog;
    pb1: TProgressBar;
    procedure btn2Click(Sender: TObject);
    procedure btn1Click(Sender: TObject);
    procedure btn3Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.btn2Click(Sender: TObject);
var
  i:integer;
  str:string;
begin

  if Trim(edt1.Text)='' then begin
    Application.MessageBox('请选择要复制的源文件！', '提示', MB_OK +
      MB_ICONINFORMATION);
    btn1.Click();
    Exit;
  end;

  try
    if StrToInt(edt2.Text)<=0 then begin
              edt2.Clear;
        edt2.SetFocus;
        Exit;
    end;

    except
      Application.MessageBox('请输入合法数值！', '提示', MB_OK +
        MB_ICONINFORMATION);
        edt2.Clear;
        edt2.SetFocus;
      exit;
      end;
      pb1.Max:=StrToInt(edt2.Text);

  if not DirectoryExists('c:\测试数据') then
    ForceDirectories('c:\测试数据');

  for i:=1 to StrToInt(edt2.Text) do
  begin
    try
    str:='c:\测试数据\'+Copy(ExtractFileName(edt1.Text),1,Length(ExtractFileName(edt1.Text))-4)+inttostr(i)+Copy(ExtractFileName(edt1.Text),Length(ExtractFileName(edt1.Text))-4+1,4);
    CopyFile(PChar(edt1.text),PChar(str),False);
    pb1.Position:=i;
    except
      end;
    end;
  Application.MessageBox('文件生成完毕,数据存放于"c:\测试数据"目录！', '提示', MB_OK +
        MB_ICONINFORMATION);
end;

procedure TForm1.btn1Click(Sender: TObject);
begin
     dlgOpen1.Execute;
     edt1.Text:=dlgOpen1.FileName;
end;

procedure TForm1.btn3Click(Sender: TObject);
begin
     Application.Terminate;
end;

end.
