因为要写工作日总结，以前的都没有写，今天要一起给补上．总结
的形式是一个一个的ｗｏｒｄ文档，要是让老板看到它们都是一天
建的就不好了。所以才想到用程序来修改这三个时间．
我用ｆｉｌｅｓｙｓｔｅｍｏｂｊｅｃｔ得到ｆｉｌｅ，但是ｆｉ
ｌｅ的ｄａｔｅｃｒｅａｔｅｄ／ｄａｔｅｌａｓｔａｃｃｅｓｓ
ｄ／ｄａｔｅｌａｓｔｍｏｄｉｆｉｅｄ都是只读属性。怎么才能
改呢？
希望跟大家探讨探讨．
给我信箱 我给你例子~
【声明】
Public Declare Function SetFileTime Lib "kernel32" Alias "SetFileTime" (ByVal hFile As Long, lpCreationTime As FILETIME, lpLastAccessTime As FILETIME, lpLastWriteTime As FILETIME) As Long
【说明】
设置文件的创建、访问及上次修改时间
【返回值】
Long，非零表示成功，零表示失败。会设置GetLastError
【参数表】
hFile ---------- Long，系统文件句柄
lpCreationTime - FILETIME，文件的创建时间
lpLastAccessTime - FILETIME，文件上一次访问的时间
lpLastWriteTime - FILETIME，文件最近一次修改的时间
以下是要用到的API函数，如果还不能解决，mail to :qbilbo@kali.com.cn。
我发个测试程序给你。
用于改变文件创建日期，最后修改日期的API，数据类型及常量。
Private Type FILETIME
dwLowDateTime As Long
dwHighDateTime As Long
End Type
Public Type SYSTEMTIME
wYear As Integer
wMonth As Integer
wDayOfWeek As Integer
wDay As Integer
wHour As Integer
wMinute As Integer
wSecond As Integer
wMilliseconds As Integer
End Type
Private Const GENERIC_READ = &H80000000
Private Const GENERIC_WRITE = &H40000000
Private Const OPEN_EXISTING = 3
Private Const FILE_SHARE_READ = &H1
Private Const FILE_SHARE_WRITE = &H2
获取文件句柄
Private Declare Function CreateFile Lib "kernel32" Alias "CreateFileA" (ByVal lpFileName As String, _
ByVal dwDesiredAccess As Long, ByVal dwShareMode As Long, _
ByVal lpSecurityAttributes As Long, ByVal dwCreationDisposition As Long, _
ByVal dwFlagsAndAttributes As Long, ByVal hTemplateFile As Long) As Long
获取文件UTC时间信息中的创建日期和最后修改日期
Private Declare Function GetFileTime Lib "kernel32" (ByVal hFile As Long, lpCreationTime As FILETIME, _
ByVal lpLastAccessTime As Long, lpLastWriteTime As FILETIME) As Long
设置文件创建日期，最后修改日期
Private Declare Function SetFileTime Lib "kernel32" (ByVal hFile As Long, lpCreationTime As FILETIME, _
lpLastAccessTime As FILETIME, lpLastWriteTime As FILETIME) As Long
将系统日期格式转换成本地日期格式
Private Declare Function SystemTimeToFileTime Lib "kernel32" (lpSystemTime As SYSTEMTIME, _
lpFileTime As FILETIME) As Long
将本地日期格式转换成系统日期格式
Private Declare Function FileTimeToSystemTime Lib "kernel32" (lpFileTime As FILETIME, _
lpSystemTime As SYSTEMTIME) As Long
将UTC时间信息转换成本也时间信息
Private Declare Function FileTimeToLocalFileTime Lib "kernel32" (lpFileTime As FILETIME, _
lpLocalFileTime As FILETIME) As Long
将本地文件时间转成UTC时间信息
Private Declare Function LocalFileTimeToFileTime Lib "kernel32" (lpLocalFileTime As FILETIME, _
lpFileTime As FILETIME) As Long
关闭文件
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
he SetFileTime function sets the date and time that a file was created, last accessed, or last modified.
BOOL SetFileTime(
HANDLE hFile, // identifies the file
CONST FILETIME *lpCreationTime, // time the file was created
CONST FILETIME *lpLastAccessTime, // time the file was last accessed
CONST FILETIME *lpLastWriteTime // time the file was last written
);
