东软总结02-文档类的相关操作

在文档类中找到序列函数Serialize（CArchive &ar）

void CHomework_jiangjieDoc::Serialize(CArchive& ar){if (ar.IsStoring()){// TODO: add storing code herear << nCount;//写入数据}else{// TODO: add loading code herear >> nCount;//读取数据}}

 

新建 文件时触发事件：找到OnNewDocument（）

BOOL CHomework_jiangjieDoc::OnNewDocument(){if (!CDocument::OnNewDocument())return FALSE;// TODO: add reinitialization code here// (SDI documents will reuse this document)nCount = 0;return TRUE;}

 

关闭程序时，提醒用户是否保存：view中要保存的动作之后添加：

pDoc->SetModifiedFlag();
