本人有一基于对话框的应用程序上有很多步，在没实现一功能后，就希望刷新当前视图，请教如何处理
以下内容引用帮助
int acedRedraw(const ads_name ent,int mode);ent The name of the entity to redraw or NULL to specify the graphics viewport
mode The mode in which to redraw
Redraws either the graphics viewport or a single entity, according to the arguments.
The following table shows the acceptable values for mode and the effect that each has. (If ent is not NULL but mode is 0, the call has no effect.)
