//一个包含两个窗体的例子, 这是工程中的内容:
program Project1;

uses
  Forms,
  Unit1 in 'Unit1.pas' {Form1},
  Unit2 in 'Unit2.pas' {Form2};

{$R *.res}

begin
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TForm1, Form1);
  Application.CreateForm(TForm2, Form2);
  Application.Run;
end.

// unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); end; var Form1: TForm1; implementation {$R *.dfm} uses Unit2; procedure TForm1.Button1Click(Sender: TObject); var num: Integer; begin num := Screen.FormCount; {当前程序中窗体的个数} ShowMessage(IntToStr(num)); {2} Screen.Forms[1].ShowModal; {显示第二个窗体} {上面这句相当于} //Form2.ShowModal; end; end.
