GDI+带农历的万年历（周历）之制作

今天在网上无意中搜索到“Vista风格日历控件”。下载之后发现，略有BUG，于是进行改进。无意中，制作出来带农历的万年历（周历版）。

运行如下图：

            int offsetY = -10;

            for (int i = 0; i < vistaCalendarList.Length; i++)
            {
                vistaCalendarList[i] = new VistaCalendar();
                vistaCalendarList[i].BackColor = System.Drawing.Color.Transparent;
                vistaCalendarList[i].CurrentDate = dateTimeNow.AddDays(i);
                vistaCalendarList[i].IsUseToday = false;
                calendarX = (i % columns) * (155 + offsetX);
                calendarY = (i / columns) * (160 + offsetY);
                vistaCalendarList[i].Location = new System.Drawing.Point(calendarX, calendarY);
                vistaCalendarList[i].Name = "vistaCalendar" + (i+1).ToString();
                vistaCalendarList[i].Size = new System.Drawing.Size(155, 160);                vistaCalendarList[i].Style = (CNPOPSOFT.Controls.VistaCalendar.VistaCalendarStyle)((i + i/columns) % styleCount);
                vistaCalendarList[i].TabIndex = i + 1;
                this.Controls.Add(vistaCalendarList[i]);
            }            // 
            // frmDemo
            // 
            this.MaximizeBox = false;
            this.MinimizeBox = false;
            this.Name = "frmDemo";
            this.Text = "Vista时钟控件";
            this.Load += new System.EventHandler(this.frmDemo_Load);
            this.ResumeLayout(false);        }
    }
}

VistaCalendar.cs中新增了CurrentDate和IsUseToday两个公共属性：
        public DateTime CurrentDate
        {
            get 
            {
                return _currentDate;
            }
            set
            {
                _currentDate = value;
            }
        }        public bool IsUseToday
        {
            get { return _isUseToday; }
            set { _isUseToday = value; }
        }

并将UpdateCurrentDateInfo();由构造函数中放到了void VistaCalendar_Paint(object sender, PaintEventArgs e)中，这样更加合理。其他地方的微小改动包括字体大小等。

在此，谨向原作者致谢！感谢他的辛勤劳动！
