引言: 請問我可以讓MonthCalendar自動一天一天的選取嗎?{當click button後} 就是說偵測今天日期後再加一天,直到2003/12/31就不再加. 因為我打算每加一天就去做特定事情.

procedure TForm1.Button1Click(Sender: TObject);
begin
  if MonthCalendar1.Date < StrToDate('2003/12/31') then
    MonthCalendar1.Date := MonthCalendar1.Date   1;
end;

unit Unit1;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  ComCtrls, DateUtils;    type
  TForm1 = class(TForm)
    MonthCalendar1: TMonthCalendar;
    procedure FormShow(Sender: TObject);
    procedure MonthCalendar1Click(Sender: TObject);
  private
    LastDate : TDate;
    { Private declarations }
  public
    { Public declarations }
  end;    var
  Form1: TForm1;    implementation    {$R *.dfm}    procedure TForm1.FormShow(Sender: TObject);
begin
  LastDate := MonthCalendar1.Date;
  MonthCalendar1.MaxDate := EncodeDate(2003,12,31);
end;    procedure TForm1.MonthCalendar1Click(Sender: TObject);
var NewDate : TDate;
begin
  if LastDate = MonthCalendar1.Date then exit;
  NewDate := MonthCalendar1.Date;
  MonthCalendar1.Date := LastDate;
  //This session make the traveral over month to stop at start/end of the new month
  //If you want it to stop in the same day of the old value, just delete this session
  if MonthOf(NewDate) > MonthOf(LastDate) then
    NewDate := EncodeDate(YearOf(NewDate),MonthOf(NewDate),1)
  else if MonthOf(NewDate) < MonthOf(LastDate) then
    NewDate := EncodeDate(YearOf(NewDate),MonthOf(NewDate),DaysInMonth(NewDate));
  //End of new Month operation
  repeat
    if MonthCalendar1.Date < NewDate then
      MonthCalendar1.Date := MonthCalendar1.Date   1
    else
      MonthCalendar1.Date := MonthCalendar1.Date - 1;
    //Do what you need to do every date
    sleep(300); //demo only pls delete
  until MonthCalendar1.Date = NewDate;
  LastDate := MonthCalendar1.Date;
end;    end.
