Question

我想请教下，delphi7怎么按一个form1中的button然后就跳出form2的代码（form1，form2都已经建了）

Answer 1

if FindglobalComponent('Form2')=nil then
Form2:=TForm2.create(self);
form2.show;

Answer 2

代码如下:
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.Show;
end;

end.
