delphi怎么才能实现登录窗体在主窗体前面显示，也就是同时显示两个窗体，只有登录后主窗体才能操作

Answer 1

做两个窗体 一个是主窗体 一个是登陆窗体. 将主窗体放在自动建立的列表里

Answer 2

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

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
testForm : Tform;
edit1 : Tedit;
begin
testForm := Tform.Create(form1);
testform.Left := form1.Left+30;
testform.Top := form1.Top+30;
testform.Width := 150;
testform.Height := 150;
testForm.ShowModal;
end;

end.
