PPC开发，窗体添加背景图片

其实很简单首先添加背景图片到所在工程，设置为嵌入式资源。接着获取嵌入式图片资源，覆写OnPaint绘制背景。

private  Image bgImage;
public  FormBase()
         {
            bgImage= new Bitmap(Assembly.GetExecutingAssembly().GetManifestResourceStream("CMclient.Image.Img_BackGround.gif"));
        }
// 绘制背景
         protected   override   void  OnPaint(PaintEventArgs e)
         {
            base.OnPaint(e);
            e.Graphics.DrawImage(bgImage, this.ClientRectangle, new Rectangle(0, 0, this.bgImage.Width, this.bgImage.Height), GraphicsUnit.Pixel);
        }
