In der Bibliothek enthaltener VBA-Code im Ordner

Die VBA-Codebibliothek enthält Code, der sich auf Ordner bezieht: zwei Snippets für die Schleifenbildung eines Ordners, eine Funktion FolderExists und eine Prozedur zum Erstellen von Ordnern mit Unterordnern.

Das Bild auf der rechten Seite zeigt das Menü Code VBA " VBA " Folder wo sich die VBA-Bibliothekseinträge ganz unten befinden. Die anderen Elemente sind Standard-VBA-Ordnerprozeduren und ein spezielles Werkzeug zum einfachen Erstellen einer Ordnerzeichenfolge.

• Array mit Unterordnern füllen mit Dir
• Schleifenordner mit Dir
• Prüfen, ob ein Ordner existiert
• Mehrere verschachtelte Verzeichnisse erstellen

Array mit Unterordnern füllen mit Dir

Dim strItemInFolder As String
Dim FolderList() As String 'The array with found folders
Dim intFoundFolders As Integer
strItemInFolder = Dir(, vbDirectory)
Do While strItemInFolder <> ""
    If ((GetAttr(strFolder & strItemInFolder) And vbDirectory) = vbDirectory) And _
        Not (strItemInFolder = "." Or strItemInFolder = "..") Then
            ReDim Preserve FolderList(intFoundFolders)
            FolderList(intFoundFolders) = strItemInFolder
            intFoundFolders = intFoundFolders + 1
    Ende wenn
    EintragInOrdner = Dir
Schleife

Schleifenordner mit Dir

Dim strItemInFolder As String
strItemInFolder = Dir(, vbDirectory)
Do While strItemInFolder <> ""
    If ((GetAttr( & strItemInFolder) And vbDirectory) = vbDirectory) And _
        Not (strItemInFolder = "." Or strItemInFolder = "") Then
        'TODO: Ersetzen Sie Debug.Print durch den Prozess, den Sie mit dem Unterordner durchführen möchten
        'Dim strFilePath As String: strFilePath = strFolder & strItemInFolder
        Debug.Print strItemInFolder
    End If
    strItemInFolder = Dir
Schleife

Prüfen, ob ein Ordner existiert

Public Function FolderExists(Directory As String) As Boolean
    If Len(Dir(Directory, vbDirectory)) > 0 Then
        If GetAttr(Directory) = vbDirectory Then
            FolderExists = True

' will create only the last (right-most) directory of a
' path specification, and all directories to the left of the
' last director must already exist. For example, the following will fail
'       MkDir "C:\Folder\Subfolder1\Subfolder2\Subfolder3"
' will fail unless "C:\Folder\Subfolder1\Subfolder2\" already
' exists. MakeDirMulti will create all the folders in
' "C:\Folder\Subfolder1\Subfolder2\Subfolder3" as required.

' At present, MakeDirMulti supports local and mapped drives,
' but not UNC paths.
' The function will return True even if no directories were
' created (all directories in DirSpec already existed).
