Application of Resource Storage Management Framework in CBT

文中介绍了在CBT课件开发系统中,采用经过改进的树型控件开发课程素材录入和管理系统素材存储结构方法,达到既符合人们的浏览习惯,也便于素材在数据库中存储、管理和进一步操作的目的。实现了使用数据库记录创建树型控件,通过使用自行设计的派生于CTreeCtrl的子类实现支持拖拽的树型控件,并利用树型控件的附加属性保存了便于检索和操作相应记录的关键信息。

Discusses the method to develop the storage framework of CBT resource management system using an improved tree control. Achieve the purpose of expressing resource in a way according with custom, and easy to store,mange,operate.
