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 here
		ar << nCount;//写入数据
	}
	else
	{
		// TODO: add loading code here
		ar >> 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();
