我想在form2中調用form1的過程test1,看到資料上面說要將過程的標題放在interface部份,含標題的整個過程放在庫單元implementation中,在form2的uses中加入了form1的名稱,但我在form1的interface中加入procedure test1;時就有錯誤,請大大們指點指點. 初學者望高手們多賜教

是uses unit的名稱吧 ex. uses unit1; 在form2使用的時候 ex. form1.test1; 發表人 - lesae 於 2004/12/30 16:15:43 發表人 - lesae 於 2004/12/30 16:18:43

zhong您好：可否将您的错误POSE上来，或参照下列，对比看看 < class="code"> unit1: 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 } procedure test;//写在这里，不能被其他unit调用 public { Public declarations } procedure test;//写在这里，可供其他unit调用 end; var Form1: TForm1; implementation uses Unit2; {$R *.dfm} //Form1的一个过程 procedure TForm1.test; begin showmessage('我是Form1的Test过程'); end; //显示出Form2来 procedure TForm1.Button1Click(Sender: TObject); begin Form2.show; end; end. unit2: unit Unit2; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm2 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form2: TForm2; implementation uses unit1; {$R *.dfm} procedure TForm2.Button1Click(Sender: TObject); begin Form1.test; end; 另：上述例子，只是冰山一角，您可以自己去查找站内相关资料，内有很多相关的介绍和例子，试试看 <> ============================= 为什么经过多年以后，得失的过程如此冷漠 =============================

引言: 以下是代碼

unit T_FORM1;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;    type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
  procedure test;//此處會錯誤Unsatisfied forward or external declaration: 'TForm1.test'
过程声明在私有部分中，不能够被其他单元给调用，如需调用，得声明在公共部分，才能给其他单元调用
    { Private declarations }
  public
    { Public declarations }
    procedure test;//声明在这里才对的
  end;    var
  Form1: TForm1;    implementation    uses T_FORM2;    {$R *.dfm}    procedure TForm1.test; //加上红色部分试试
begin
showmessage('hello');
end;    procedure TForm1.Button1Click(Sender: TObject);
begin
test;
end;    procedure TForm1.Button2Click(Sender: TObject);
begin
FORM2.Show;
end;    end.    unit T_FORM2;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;    type
  TForm2 = class(TForm)
    Button1: TButton;
  private
    { Private declarations }
  public
    { Public declarations }
  end;    var
  Form2: TForm2;    implementation    USES T_FORM1;
