使用函数:
System.IOUtils.TDirectory.GetAttributes//获取属性
System.IOUtils.TDirectory.SetAttributes//设置属性
注:次例未添加异常处理。
补充一句代码:
CheckListBox1.CheckAll(vcl.StdCtrls.TCheckBoxState(0), False, False);//ListCheckBox取消所有选中
示例:
代码:
unit Unit1; interface uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants,
System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, System.TypInfo, Vcl.StdCtrls,
Vcl.CheckLst, Vcl.FileCtrl, System.IOUtils; type
TForm1 = class(TForm)
