如何从 VBA 中的文件对话框对象中获取单个文件名（对于 MS Access 2007）？

Question

如何更改代码以获取文件名而不是目录名？ openDialog.InitialFilename 给我目录名称。
openDialog.FileName 给我错误“找不到方法或数据成员”。

Private Sub btnEditPhoto_Click()
    If (txtImageName > "") Then

        Application.FollowHyperlink txtImageName

    Else
        Dim openDialog As Office.FileDialog

        Set openDialog = Application.FileDialog(msoFileDialogFilePicker)

            openDialog.Filters.Clear
            openDialog.Filters.Add "JPEG Files", "*.jpg"

        Dim pickedFile As Boolean
            pickedFile = openDialog.Show

        If pickedFile Then
                txtImageName.SetFocus
                txtImageName.Text = openDialog.InitialFileName
        End If

    End If

End Sub

Answer 1

您想要：

OpenDialog.SelectedItems.Item(1)

代替：

OpenDialog.InitialFileName

因为您不允许多重选择。

所以：

''Reference Microsoft Office x.x Object Library
Dim openDialog As Office.FileDialog

Set openDialog = Application.FileDialog(msoFileDialogFilePicker)
openDialog.Filters.Clear
openDialog.Filters.Add "JPEG Files", "*.jpg"

If openDialog.Show Then
    ''SelectedItems is not zero based

    ''Do not use .Text property in MS Access except
    ''in special cases, then you will not have to set focus
    ''txtImageName.SetFocus

    txtImageName = openDialog.SelectedItems(1)
End If

如果使用AllowMultiSelect，则需要迭代SelectedItems

''Reference Microsoft Office x.x Object Library
Dim openDialog As Office.FileDialog
Dim i As Integer

Set openDialog = Application.FileDialog(msoFileDialogFilePicker)
'Use ctl or shift + click to select more than one file
openDialog.AllowMultiSelect = True
openDialog.Filters.Clear
openDialog.Filters.Add "JPEG Files", "*.jpg"

If openDialog.Show Then
    For i = 1 To openDialog.SelectedItems.Count
        Imagelst = Imagelst & ";" & openDialog.SelectedItems(i)
    Next
End If

Answer 2

我需要选择一个文本文件...这就是我所做的...它工作得很好。

' Get the File
'----------------------------------------------------------
Dim dialog As Object
Dim pickedfile As Boolean
Dim myfile As String
Set dialog = Application.FileDialog(msoFileDialogFilePicker)
With dialog
    .AllowMultiSelect = False
    .Title = "Please pick the file to convert."
    .Filters.Clear
    .Filters.Add "Text Files", "*.TXT"
    .Filters.Add "All Files", "*.*"
    pickedfile = False
    pickedfile = .Show
    If pickedfile Then
    myfile = .SelectedItems.Item(1)
    End If
End With
'----------------------------------------------------------

另外...您可以将对话框类型替换为...

Set dialog = Application.FileDialog(msoFileDialogOpen)

并且它同样有效。

Private Sub Command135_Click()

Dim dialog As Object
Dim pickedfile As Boolean
Dim myfile As String
Set dialog = Application.FileDialog(1)
With dialog
    .AllowMultiSelect = False
    .Title = "Please pick the file to convert."
    .Filters.Clear
    .Filters.Add "Picture Files", "*.Jpg"
    .Filters.Add "All Files", "*.*"
    pickedfile = False
    pickedfile = .Show
    If pickedfile Then
    myfile = .SelectedItems.Item(1)
    End If
End With

Me.Form.Picture = myfile
End Sub


Command_135=Button Name
Me.Form.Picture = "The Control Name"
