Excel單元格自動打開/關閉文件窗口並將文件名和路徑作爲單元格值

Question

我是Excel中的新手。我需要下面的東西。

當在一個小區用戶點擊或輸入到單元格：

1. 它會自動打開/關閉文件窗口。

2. 當用戶選擇一個文件，它應該拿起路徑/文件名，並把進入細胞內，就像c:\folder1\file1.ext

3. 如果用戶選擇一個以上的文件，它應該拿起所有的路徑/文件名進入細胞，以|作爲分隔符。像c:\folder1\file1.ext|d:\folder2\file2.ext

4. 如果一個小區用戶點擊或進入細胞第二次，它應該一直存在的路徑/文件名，並讓在數量上增加其他的路徑/ filnames他們像3

這與Sid的類似，只是讓你雙擊任何一個單元打開文件對話框。

在模塊

Public Function getList(Optional ByVal Target As Range = Nothing) As String 
Dim Dialog As FileDialog 
Dim File As Integer 
Dim Index As Integer 

Dim List() As String 
Dim Item As Integer 
Dim Skip As Boolean 

Set Dialog = Application.FileDialog(msoFileDialogFilePicker) 

File = Dialog.Show 

If File = -1 Then 
    ' Get a list of any pre-existing files and clear the cell 
    If Not Target Is Nothing Then 
     List = Split(Target.Value, "|") 
     Target.Value = "" 
    End If 
    ' Loop through all selected files, checking them against any pre-existing ones to prevent duplicates 
    For Index = 1 To Dialog.SelectedItems.Count 
     Skip = False 
     For Item = LBound(List) To UBound(List) 
      If List(Item) = Dialog.SelectedItems(Index) Then 
       Skip = True 
       Exit For 
      End If 
     Next Item 
     If Skip = False Then 
      If Result = "" Then 
       Result = Dialog.SelectedItems(Index) 
      Else 
       Result = Result & "|" & Dialog.SelectedItems(Index) 
      End If 
     End If 
    Next Index 
    ' Loop through the pre-existing files and add them to the result 
    For Item = UBound(List) To LBound(List) Step -1 
     If Not List(Item) = "" Then 
      If Result = "" Then 
       Result = List(Item) 
      Else 
       Result = List(Item) & "|" & Result 
      End If 
     End If 
    Next Item 
    Set Dialog = Nothing 
    ' Set the target output if specified 
    If Not Target Is Nothing Then 
     Target.Value = Result 
    End If 
    ' Return the string result 
    getList = Result 

End If 
End Function 

在工作表中的代碼

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean) 
    If Target.Rows.Count = 1 And Target.Columns.Count = 1 Then getList Target 
End Sub 

更新 我已經改變了的GetList功能（它也不會斷裂，只是做它做更多）

• 它將使你雙擊任一單元格，這將打開一個文件對話框。
• 您可以選擇1個（或更多）文件
• 文件名將與「|」特點，並提出在靶細胞
• 如果預先存在的任何文件都在細胞內，新的會被追加到它們

但是，它並不支持按Enter，打開文件對話框中，必須雙擊該單元格。

更新 爲了幫助VMO（評論員）

工作表模塊中的代碼：

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean) 
    If Target.Rows.Count = 1 And Target.Columns.Count = 1 Then 
     If Target.Address = "$A$1" Then ' See Notes Below 
      Target.Value = getList(Target) 
     End If 
    End If 
End Sub 

要限制單元格是雙click'able，你將需要使用類似的東西。你可以改變$A$1爲任何你想要的或找到一種方法來確定目標範圍的名稱（不是太難）

如果你的工作表沒有被鎖定，單擊的單元格將保持焦點，並處於編輯模式，即有點討厭。鎖定單元格，在以前版本的Excel中修復此問題（我認爲它在v.2010 +中無效）

模塊中的代碼（getList）可以保持幾乎完全相同（儘管您可能想要刪除所有處理多個文件的代碼，但不是必需的）。您只需添加一行代碼即可。

....... 
Dim Skip As Boolean 

Set Dialog = Application.FileDialog(msoFileDialogFilePicker) 

Dialog.AllowMultiSelect = False ' This will restrict the dialogue to a single result 

File = Dialog.Show 

If File = -1 Then 
...... 

希望這會有所幫助，我明白你在問什麼！

Answer 2

這應該做的伎倆。第一個子例程是用戶單擊單元格時觸發的事件。更改第一個if語句中的行和列號以更改目標單元格。您可以將所有這些代碼放入您想要的工作表的代碼模塊中。

Private Sub Worksheet_SelectionChange(ByVal Target As Range) 

    Dim filenames() As String 
    Dim filename As Variant 
    Dim filelist As String 

    ' Make sure the user clicked our target cell 

    If Target.Row = 2 And Target.Column = 2 Then 

     ' Get a list of filenames 

     filenames = GetFileNames 

     ' Make sure we got some filenames 

     If UBound(filenames) > 0 Then 

      ' Go through the filenames, adding each to the output string 

      For Each filename In filenames 
       filelist = filelist & CStr(filename) & "|" 
      Next filename 

      ' Remove the final delimiter 

      filelist = Left(filelist, Len(filelist) - 2) 

      ' Apply the output string to the target cell (adding another 
      ' delimiter if there is already text in there) 

      If Not Target.Value = "" Then 
       Target.Value = Target.Value & "|" 
      End If 

      Target.Value = Target.Value & filelist 

     End If 

    End If 

End Sub 

以下函數是調用該函數打開文件對話框並檢索文件名。

Private Function GetFileNames() As String() 

    Dim dlg As FileDialog 
    Dim filenames() As String 
    Dim i As Integer 

    ' Open a file dialogue 

    Set dlg = Application.FileDialog(msoFileDialogFilePicker) 

    With dlg 
     .ButtonName = "Select"     ' Text of select/open button 
     .AllowMultiSelect = True    ' Allows more than one file to be selected 
     .Filters.Add "All Files", "*.*", 1  ' File filter 
     .Title = "Select file(s)"    ' Title of dialogue 
     .InitialView = msoFileDialogViewDetails 
     .Show 

     ' Redimension the array with the required number of filenames 

     ReDim filenames(.SelectedItems.Count) 

     ' Add each retrieved filename to the array 

     For i = 1 To .SelectedItems.Count 
      filenames(i - 1) = .SelectedItems(i) 
     Next i 

    End With 

    ' Clean up and return the array 

    Set dlg = Nothing 
    GetFileNames = filenames 

End Function
