dear 請問我如何於主畫面中增加一個新的button，並接下後可跳到另一個畫面維護資料呢？這其中的連結，程式需如何撰寫與連接呢？由於我是個初學者，功力很差，還麻煩幫忙解說時詳細些，謝謝你大爺！

建立新project, 並new兩個form    form1 檔案 Unit1.pas:

unit Unit1;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;    type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;    var
  Form1: TForm1;    implementation    uses Unit2;    {$R *.dfm}    procedure TForm1.Button1Click(Sender: TObject);
begin
   //form2 按下任何按鍵都會回到form1
   Form2.ShowModal;       //或 只有在form2按下OK 才會回到 form1
   {
   repeat
   until (Form2.ShowModal=mrOK);
   }
end;    end.     

form2 檔案 Unit2.pas:

unit Unit2;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, Buttons;    type
  TForm2 = class(TForm)
    BitBtn_OK: TBitBtn;
    BitBtn_Cancel: TBitBtn;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;    var
  Form2: TForm2;    implementation    {$R *.dfm}    procedure TForm2.FormCreate(Sender: TObject);
begin
   BitBtn_OK.Kind:=bkOK;
   BitBtn_Cancel.Kind:=bkCancel;
end;    end.     

dear 非常謝謝你的解說，感謝，但為何我依樣畫胡盧時，會出現以下error呢？謝謝！ error module 'form' link to module 'dm' which cannot be found in the current project . Do you wish to remove/redirect the links to another module?
