修改的Vista风格多功能日历Demo

Vista风格日历程序来源于网上开源程序，首先感谢下原作者的无私奉献！

在原来基础上稍作修改添加了一些演示，效果如图：

 

 

 

新增演示：1，gdi绘制小图标,

              2，带图标的ComboBox 

 

实际应用：

           可以抓取气象网上的气象信息，做一个完善的小程序。

代码：

带图标的ComboBox

public   class  UIcombox : ComboBox
    {
         public  UIcombox()
        {
            DrawMode  =  DrawMode.OwnerDrawFixed;
        }
         private  ImageList _ListaImg  =   new  ImageList();

         public  ImageList ImageList
        {
             get
            {
                 return  _ListaImg;
            }
             set
            {
                _ListaImg  =  value;
            }
        }

         private   bool  _ShowTitle  =   true ;
         public   bool  ShowTitle
        {
             get
            {
                 return  _ShowTitle;
            }
             set
            {
                _ShowTitle  =  value;
            }
        }
         protected   override   void  OnDrawItem(DrawItemEventArgs e)
        {
             if  (e.Index  >=   0 )
            {
                e.DrawBackground();
                e.DrawFocusRectangle();
                Rectangle bounds  =   new  Rectangle();

                bounds  =  e.Bounds;

                 string  s  =   "" ;
                 if  (_ShowTitle  ==   true )
                {
                    s  =   this .Items[e.Index].ToString();
                }

                 try
                {
                     if  (_ListaImg.Images.Count  !=   0 )
                    {
                         // _ListaImg.ImageSize = new Size(this.Height - 8, this.Height - 8);  /*此处new操作之后_ListImg会为NULL*/
                        _ListaImg.Draw(e.Graphics, bounds.Left, bounds.Top, e.Index);
                        e.Graphics.DrawString(s, e.Font,  new  SolidBrush(e.ForeColor), bounds.Left  +  _ListaImg.Images[e.Index].Width, bounds.Top);
                    }
                     else
                    {
                        e.Graphics.DrawString(s, e.Font,  new  SolidBrush(e.ForeColor), bounds.Left, bounds.Top);
                    }
                }
                 catch     /* ImageList中Images尽量与ComBox中Items对应 */
                {
                    e.Graphics.DrawString(s, e.Font,  new  SolidBrush(e.ForeColor), bounds.Left, bounds.Top);
                }
            }
             base .OnDrawItem(e);
        }
    }
