访问VBA:如何返回您浏览的文件的路径

时间:2011-07-27 22:22:54

标签: excel ms-access vba filepath

我想返回我浏览过的excel文件的完整路径。 使用以下内容,

Set dlg = Application.FileDialog(msoFileDialogFilePicker)

dlg.Title = "Select Excel Spreadsheet to import"
dlg.AllowMultiSelect = False
If dlg.Show = -1 Then
    dataPath = dlg.InitialFileName
    Me!browseDataPath = dlg.InitialFileName

End If

我可以打开对话框并返回文件所在的目录,但是此代码不会在路径末尾附加文件名(例如blabla.xls)。

例如,如果我的C盘有blabla.xls,它只会返回C:\

如何让它返回C:\ blabla.xls(或者excel文件的名称是什么)?

谢谢!

3 个答案:

答案 0 :(得分:3)

dataPath = dlg.SelectedItems(1)
Me!browseDataPath = dataPath

由于您已禁用多选,因此获取第一个(基于一个)项就足够了。

将此代码粘贴到模块中。

Function GetFolder(strPath As String) As String

Dim fldr As FileDialog
Set fldr = Application.FileDialog(msoFileDialogFolderPicker)

With fldr
    .Title = "Select a Folder"
    .AllowMultiSelect = False
    .InitialFileName = strPath

    If .Show <> -1 Then GoTo NextCode
    sItem = .SelectedItems(1)
End With

NextCode:

GetFolder = sItem
Sheets("Home").OLEObjects("TextBox1").Object.Value = sItem
Set fldr = Nothing

End Function

'**And then call it by using**

Private sub button1_click()
   call GetFolder("Any default folder path")
end sub
