下面是在.net framework 2.0平台下的一个报错：

[Exception] Out of memory.
[Message]    System.OutOfMemoryException
[StackTrace]    at System.Drawing.Graphics.FromHdcInternal(IntPtr hdc)
   at System.Drawing.BufferedGraphicsContext.CreateBuffer(IntPtr src, Int32 offsetX, Int32 offsetY, Int32 width, Int32 height)
   at System.Drawing.BufferedGraphicsContext.AllocBuffer(Graphics targetGraphics, IntPtr targetDC, Rectangle targetRectangle)

   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

这个报错发生的概率非常的小，而且复现也是比较困难的。从该链接http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=161567&SiteID=1里你会发现的确是GDI+的bug。任何东西的成熟都需要一个过程，新生事物不可能一下子就是无敌状态。工业强度的软件和随便写几行代码绝对是不可同日而语的。

下面还有GDI+的一个报错，好晕阿

[Exception] A generic error occurred in GDI+.
