[Windows Develop] Ghost_drag_image DL : 0: Have you noticed the cool ghost image that Windows Explorer produces when you start dragging files/folders from it? Well, I wanted to implement this in a C# project when dragging files between it and Windows Explorer. After a lot of Googling, I found out that there are three directions to start working on, as follows: Using a \"custom\" cursor created from a MemoryStream initialized from an Image, as shown in this article. Using the ImageList_BeginDrag and related APIs, as shown in this article: Dragging tree nodes in C#. Using the IDragSourceHelper and IDropTargetHelper interfaces.

[RichEdit] ManOriKnowledge DL : 0: 最近弄一个可以编辑显示文本、图片、公式、表格、超链接等内容的东东，将其保存好数据库（DB4O），然后直接在内存中打开。最先想到的当然是dotNet的RichTextBox，但它对这些格式数据支持并不好，尤其是上下标。然后就是微软的Office Framer Control，没有什么问题，但是需要运行word进程，那玩意太庞大，尤其是在打开多个文档的时候占用内存过多。最后想到了wpf的Flowdocment，它虽然不直接支持公式，但在能直接将相关内容转换为图片形式，且不会改变显示样式。使用WPF的richTextBox可以直接将word编辑好的内容复制过来，然后保存。同时文档保存形式也就讲究，应该保存为XamlPackage，这是一种压缩格式，把流文档的各种相关数据一同保存，因此很省事，不用关系连接或图片、多媒体的数据源问题。当然XamlPackage只保存Section节点。在数据库中文档用byte[]表示，从数据库中打开文档时，可以使用byte[]实例化MemoryStream然后直接加载到相应的流文档显示控件中，但保存到数据库时却需要使用临时文件转储。相应的代码如下（C#）：
