VB怎么获取文件创建时间
Set fs = CreateObject("Scripting.FileSystemObject") '创建FileSystemObject 对象Set f = fs.GetFile("C:\123.exe ") '返回指定路径文件所对应的 File 对象
'File 对象的 DateCreated 属性返回该文件夹的创建日期和时间
'File 对象的 DateLastModified 属性返回最后一次修改该文件的日期和时间
'File 对象的 DateLastAccessed 属性返回最后一次访问该文件的日期和时间
MsgBox "创建时间：" & f.DateCreated & vbCrLf & "修改时间：" & f.DateLastModified & vbCrLf & "访问时间：" & f.DateLastAccessed, vbInformation, f.Name & "属性" --------------------编程问答-------------------- 有什么问题？
还可以用API还获得。
还有vb6的函数FileDateTime，不过它可能返回的是最后修改时间。

lz不是已经获得文件的创建日期和时间了吗
