遍历你需要查找的位置的文件,并用GetFileTime获取文件最后访问时间,计算与当前时间间隔,删除。
#3
可以使用 CFileFind 类查找指定目录下的文件,然后使用 CFileFind::GetCreationTime(创建时间)、CFileFind::GetLastAccessTime(最后访问时间)、CFileFind::GetLastWriteTime(最后修改时间),获取文件的时间,最后使用 DeleteFile 删除文件。
#4
试试先
#5
这是删除C:\1\下面创建时间小于2009-2-23 18:50 1秒的
CFileFind ff;
CString szDir="c:\\1\\*.*";
BOOL res=ff.FindFile(szDir);
while(res)
{
res=ff.FindNextFile();
if(!ff.IsDirectory()&&!ff.IsDots())
{
CTime fTime;
CTime time(2009,2,23,18,50,1);
ff.GetCreationTime(fTime);
if(fTime<time)
{
CString path="c:\\1\\";
path+=ff.GetFileName();
DeleteFile(path);
}
}
}
ff.Close();
}

大家帮我看看啊。

强,,顶一下。
#9
yuzhongzhu帮了大忙了,不过再改进一下变成“删除与当前系统时间相隔特定时间(比如说一星期)的文件”用CTime类中的“-”操作来判断减之后的结果是否大于7天从而来删除文件也应该能够实现吧
#10
我也正愁这个问题 谢了啊 呵呵

//查找目录下指定时间以前的文件
CString strDir=m_SelFolder;
int nNum=SearchFile(m_SelFolder);
CString str="";
str.Format("该文件夹下文件数为%d!",nNum);
MessageBox(str);
}
int CDelfilesonTimeDlg::SearchFile(CString strDir)
{
CFileFind filefind;
int m_nNum=0;
CString szDir=strDir; //文件目录
if (szDir.Right(1)!="\\")
szDir+="\\";
szDir+="*.*";
BOOL bRes=filefind.FindFile(szDir);
while(bRes)
{
bRes=filefind.FindNextFile();
// if(filefind.GetCreationTime<m_Seltime)
if(!filefind.IsDirectory()&&!filefind.IsDots())
{
if(filefind.GetCreationTime<m_Seltime)
m_nNum++;
}
else if (filefind.IsDirectory()&&!filefind.IsDots())
SearchFile(filefind.GetFilePath());
}
filefind.Close();
return m_nNum;
}
但现在问题是比对时间报错。用的vc中自带的date time picker控件,帮定了一个变量,在和filefind.get creationtime比较时报错,再者,删除功能还没实现。

大家帮我看看啊。

强,,顶一下。

yuzhongzhu帮了大忙了,不过再改进一下变成“删除与当前系统时间相隔特定时间(比如说一星期)的文件”用CTime类中的“-”操作来判断减之后的结果是否大于7天从而来删除文件也应该能够实现吧

我也正愁这个问题 谢了啊 呵呵
