我编写了一些 Excel VBA 代码来将文件名、版本和上次修改日期/时间添加到工作表中。代码似乎工作正常,除了有时Last Modified Date
文件的时间部分与我在资源管理器窗口中看到的时间相比正好向前或向后 1 小时。
我注意到如果我执行dir
命令,我的代码返回的值与 cmd 窗口中显示的修改日期/时间相同。
例如,如果我在system32文件夹中查找dbghelp.dll文件:
C:\Windows\System32>dir dbghelp.*
Volume in drive C has no label.
Volume Serial Number is 16E8-4159
Directory of C:\Windows\System32
21/11/2010 04:24 1,087,488 dbghelp.dll
1 File(s) 1,087,488 bytes
0 Dir(s) 60,439,101,440 bytes free
C:\Windows\System32>
但资源管理器窗口中的同一文件显示修改时间为2010 年 11 月 21 日 03:24 - 1 小时前。
我编写的代码返回 cmd 窗口时间,而我想要资源管理器窗口时间:
Sub GetFileDetails()
Dim path As String
Dim objFSO As Object
Dim objFile As Object
Dim objFolder As Object
Dim loopCount As Integer
Dim pathCheck As Boolean
'Prompt for directory path
path = InputBox(Prompt:="Enter file path", Title:="Enter file path", Default:="")
If (path = "" Or path = vbNullString) Then
MsgBox ("Invalid path - exiting")
Exit Sub
End If
'Required for interacting with filesystem
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(path)
'1st row for path title, 2nd row for column headings
loopCount = 3
For Each objFile In objFolder.Files
Range("A" & loopCount).Value = objFile.Name
Range("B" & loopCount).Value = objFSO.GetFileVersion(objFile)
Range("C" & loopCount).Value = objFile.DateLastModified
'Combine Version and Modified
If Range("B" & loopCount).Value <> "" Then
Range("D" & loopCount).Value = Range("B" & loopCount).Value & ", " & Range("C" & loopCount).Value
Else
Range("D" & loopCount).Value = Range("C" & loopCount).Value
End If
loopCount = loopCount + 1
Next
'Set up headings
Range("A" & 1).Value = (loopCount - 3) & " files found in " & path
Range("A" & 2).Value = "FileName"
Range("B" & 2).Value = "Version"
Range("C" & 2).Value = "Modified"
Range("D" & 2).Value = "Version & Modified"
End Sub
如果有人可以对这个问题有所了解 - 将不胜感激。
===EDIT=== 这是我想出的代码,它总是给我与资源管理器窗口中显示的时间相同的时间:
