在文件夾中創建文件名數組-Excel VBA

Question

我當前正在將Application.GetOpenFilename與MultiSelect：= True結合使用，以允許用戶在一個文件夾中選擇一個或多個文件，然后將所有文件中的數據導入到工作表中。 如果選擇了多個文件，則將每個文件中的數據附加到前一個文件中的數據中，直到導入所有選定文件。

我現在有一個實例，其中文本文件存儲在特定文件夾的子文件夾中，並且這些子文件夾是基於訂單號創建的。 我現在嘗試將父文件夾定義為變量，允許用戶使用Application.InputBox輸入子文件夾名稱，然后自動從用戶指定的子文件夾中的所有.txt文件中導入數據。 我掛斷了運行時錯誤'53'，找不到文件錯誤。 我知道使用GetOpenFilename方法會創建一個文件名數組，我試圖通過創建文件名數組來復制此文件名，但顯然我缺少了一些東西。

我基本上是在嘗試從類似以下的文件中導入所有.txt文件：

C：\\ AOI_DATA64 \\ SPC_DataLog \\ IspnDetails \\ 用戶定義的子文件夾 \\ * .txt

使用Application.GetOpenFilename的代碼：

如我的評論中所述，您的帖子中有很多事情要做。 但是，專注於此

我現在嘗試將父文件夾定義為變量，允許用戶使用Application.InputBox輸入子文件夾名稱，然后自動從用戶指定的子文件夾中的所有.txt文件中導入數據。

我有一個解決方案-您可以創建一個存儲每個文件（路徑和文件名）的數組，您應該可以使用該數組來獲取文件名，然后執行所需的任何操作：

Sub import_files()
Dim files As String
Dim parentDir As String

parentDir = InputBox("Please input the directory you want to import files from")
If parentDir = "" Then Exit Sub 'If they hit "Cancel" or don't put anything.
' parentDir = GetFolder() 'UNCOMMENT THIS if you want the user to select a folder via "Windows Explorer"
files = LoopThroughFiles(parentDir, "txt")
' Debug.Print (files)

Dim iFiles() As String
iFiles() = Split(files, ",")

Dim i As Long
For i = LBound(iFiles) To UBound(iFiles)
    If iFiles(i) <> "" Then
        Debug.Print ("File located: " + parentDir + "\" + iFiles(i))
        ' THIS IS YOUR ARRAY, `iFILES`, SO HERE IS WHERE YOU DO STUFF
    End If
Next i

End Sub
Private Function LoopThroughFiles(inputDirectoryToScanForFile, filenameCriteria) As String
'https://stackoverflow.com/a/45749626/4650297
Dim tmpOut As String
    Dim StrFile As String
    'Debug.Print "in LoopThroughFiles. inputDirectoryToScanForFile: ", inputDirectoryToScanForFile
    StrFile = Dir(inputDirectoryToScanForFile & "\*" & filenameCriteria)
    Do While Len(StrFile) > 0
        ' Debug.Print StrFile
