有关分割视中切换View的问题

同意楼上的观点
视图没有必要删除的
只要在 CDocument中调用UpDateAllViews函数。
然后在 View中调用 WM_UPDATE响应就完全能够解决同步刷新的问题了
没有必要删除的
用条目值来传递视图相应

对啊，要实现视图的切换，没有必要删除旧的视图。你用SetDlgCtrlID把每个视图都设置一个不同的ID，要切换的时候只要根据ID值用ShowWindow()把旧的视图隐藏并把新的视图显示出来，然后用SetActiveView来设置活动的视图就行了（把活动视图的ID设为IDW_PANE_FIRST)。

to webber84(糕鱼昏):
在没有分割视的框架中，切换视图我是按你的方法来做的。但在有分割视的框架中，好像不太行。
