上次发帖我自己没说清楚,帖子沉了,现在再发一次,希望大哥们帮忙
我想用VB做一个可以设置文件夹时间的小工具,用来修改PSP上的排列
显示的顺序。
我是想这样做的,点一下按钮,就将文件夹的创建时间修改TEXT里设置的时间,我在网上找到的
那些代码都是只能将文件夹改成与系统当前一样的时间,不能自己设置。大家有更好的代码么?共享一下
或者发到

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
参数 类型及说明
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
