请问如何完善下面的功能，RichEdit显示GIF动画？现在能够在RichEdit中添加BMP与GIF图片，
GIF也能动，想实现的功能是如何能存储RichEdit中内容到sql2000，并且能够读取，保证读出
后格式一样，且GIF也能动！请问该怎么改软件？下面是软件的下载链接！分不够开帖再加，前提要源码，可以发到，好用立即再加500分！

左侧Richedit中添加Gif时最好可以用OpenPictureDialog打开选择添加，添加好后再存到数据库中，可以设个编号如：001，然后再根据编号001读出来放到右侧Richedite2中，格式不变，gif能动。
为什么会这样？不是已经导入类型库了吗？怎么还要注册DLL吗?
