我在弄清楚如何获取文件夹名称以输出到MS access中的单独字段时遇到麻烦。到目前为止,我已经设法使用了Allen Browne脚本并将其调整为将文件名和路径输出为一个字段。
此搜索中的所有文件都包含在子文件夹中,对于我而言,在单独的字段中输出最后一个子文件夹名称非常重要。像这样:
代码如下:
Option Compare Database
Option Explicit
'list files to tables
'http://allenbrowne.com/ser-59alt.html
Dim gCount As Long ' added by Crystal
Sub runListFiles()
'Usage example.
Dim strPath As String _,strFileSpec As String _,booIncludeSubfolders As Boolean
strPath = "H:\Pictures\2019"
strFileSpec = "*.*"
booIncludeSubfolders = True
ListFilesToTable strPath,strFileSpec,booIncludeSubfolders
End Sub
'crystal modified parameter specification for strFileSpec by adding default value
Public Function ListFilesToTable(strPath As String _,Optional strFileSpec As String = "*.*" _,Optional bIncludeSubfolders As Boolean _
)
On Error GoTo Err_Handler
'Purpose: List the files in the path.
'Arguments: strPath = the path to search.
' strFileSpec = "*.*" unless you specify differently.
' bIncludeSubfolders: If True,returns results from subdirectories of strPath as well.
'Method: FilDir() adds items to a collection,calling itself recursively for subfolders.
Dim colDirList As New Collection
Dim varitem As Variant
Dim rst As DAO.Recordset
Dim mStartTime As Date _,mSeconds As Long _,mMin As Long _,mMsg As String
mStartTime = Now()
'--------
Call FillDirToTable(colDirList,strPath,bIncludeSubfolders)
mSeconds = DateDiff("s",mStartTime,Now())
mMin = mSeconds \ 60
If mMin > 0 Then
mMsg = mMin & " min "
mSeconds = mSeconds - (mMin * 60)
Else
mMsg = ""
End If
mMsg = mMsg & mSeconds & " seconds"
MsgBox "Done adding " & Format(gCount,"#,##0") & " files from " & strPath _
& IIf(Len(Trim(strFileSpec)) > 0," for file specification --> " & strFileSpec,"") _
