本文講述了Delphi讀取系統(tǒng)時間與日期的實現(xiàn)方法，首先設置各個控件用于顯示時間、讀取時間與設置時間。再添加如下代碼：
unit Unit1;interfaceuses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls;type TForm1 = class(TForm) Button1: TButton; Memo1: TMemo; Button2: TButton; procedure Button1Click(Sender: TObject); procedure FormCreate(Sender: TObject); procedure Button2Click(Sender: TObject); private { Private declarations } public { Public declarations } end;var Form1: TForm1;implementation{$R *.DFM}uses ShellAPI;function SetSystemDateTime(Year, Month, Day, Hour, Minute, Second: word): integer; export; procedure SetDate(Year, Month, Day: Word); assembler; asm MOV CX,Year MOV DH,BYTE PTR Month MOV DL,BYTE PTR Day MOV AH,2BH INT 21H end; procedure SetTime(Hour, Minute, Second, Sec100: Word); assembler; asm MOV CH,BYTE PTR Hour MOV CL,BYTE PTR Minute MOV DH,BYTE PTR Second MOV DL,BYTE PTR Sec100 MOV AH,2DH INT 21H end;begin SetDate(Year, Month, Day); SetTime(Hour, Minute + 1, Second, 0); result := 1;end;procedure TForm1.Button1Click(Sender: TObject);var st : TSYSTEMTIME;begin //得到系統(tǒng)時間 GetSystemTime(st); //顯示系統(tǒng)時間 Memo1.Lines.Add('系統(tǒng)時間 = ' + IntToStr(st.wmonth) + '/' + IntToStr(st.wDay) + '/' + IntToStr(st.wYear) + ' ' + IntToStr(st.wHour) + ':' + IntToStr(st.wMinute) + ':' + IntToStr(st.wSecond));end;procedure TForm1.FormCreate(Sender: TObject);begin Memo1.Lines.Clear;end;procedure TForm1.Button2Click(Sender: TObject);var st: TSYSTEMTIME;begin DateTimeToSystemTime(StrToDatetime('2002-06-23 15:39:46' ),st); SetSystemTime(st);end;end.新聞熱點
