采用Delphi开发环境编写的一个简单代码

unit Main;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

uses DeviceTypeDialog;

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
var
  l_DeviceTypeDlg: TDeviceTypeDlg;
begin
  l_DeviceTypeDlg:= TDeviceTypeDlg.Create(nil);
  try
    if not l_DeviceTypeDlg.Execute then exit;
    
    case l_DeviceTypeDlg.DeviceType of
      dtHDR: Edit1.Text := '硬盘录像机';
      dtPTL: Edit1.Text := '云台';
      dtPTLController: Edit1.Text := '云台控制器';
    else
      Edit1.Text := '无效设备';
    end;

  finally
    l_DeviceTypeDlg.Free;
  end;
end;

end.
