我有碼開具有可變日期的文件,如下圖所示。如果不在輸入框中輸入m.d.y.xls,此代碼將不起作用。我只想輸入m.d.y到輸入框中。請看一下,讓我知道我缺少的東西。謝謝!Excel的VBA - 附加的.xls爲filename打開文件

Dim wbkOpen As Workbook 
Dim strFilePath As String 
Dim strFileName As String 
strFilePath = "D:\Users\stefan.bagnato\Desktop\Daily Performance Summary\Agent Group Daily Summary " 
strFileName = InputBox("Enter last Friday's date in the format M.D.Y", "Friday's Date") 
Set wbkOpen = Workbooks.Open(strFilePath & strFileName, False, True)

這是基本的字符串連接:

strFilePath & strFileName & ".xls" 

你或許應該檢查以確保該文件存在,否則會出現錯誤:

Dim fullFileName As String 
strFilePath & strFileName & ".xls" 
If Dir(fullFileName) = "" Then 
    MsgBox "Invalid filename!" 
    Exit Sub 
End If 
Set wbkOpen = Workbooks.Open(fullFileName, False, True) 

理想情況下,你能避免用戶 - 輸入(這是容易出錯)共:

Const strFilePath As String = "D:\Users\stefan.bagnato\Desktop\Daily Performance Summary\Agent Group Daily Summary " 
Dim wbkOpen As Workbook 
Dim LastFridayDate As String 
Dim fullFileName As String 
Dim fdlg as FileDialog 
LastFridayDate = Format(Date - (Weekday(Date, vbFriday) - 1), "m.d.yy") 
fullFileName = strFilePath & LastFridayDate & ".xls" 

If Dir(fullFileName) = "" Then 
    If MsgBox("The file named " & fullFileName & " doesn't exist. Would you like to manually locate the file?", vbYesNo) = vbNo Then 
     Exit Sub 
    Else 
     Set fdlg = Application.FileDialog(msoFileDialogOpen) 
     '## Opens the fileDialog in the normal folder where these files should exist 
     fdlg.InitialFileName = strFilePath 
     '## Display the fileDialog to the user 
     fdlg.Show 
     '## Validate the fileDialog hasn't been canceled 
     If fdlg.SelectedItems.Count <> 0 Then 
      '## Return the value of the item selected by the user 
      fullFileName = fdlg.SelectedItems(1) 
     Else: 
      MsgBox "No file selected, exiting procedure..." 
     End If 
    End If 
End If 
Set wbkOpen = Workbooks.Open(fullFileName, False, True) 

當然允許用戶手動選擇的文件最終可能需要額外的驗證和/或錯誤處理(即,如果他們選擇了錯誤的文件是什麼?程序如何知道哪些日期正確日[我打賭它不能,沒有做一個醜陋的暴力循環仍使很多的假設可能並不總是抱着]如果他們選擇的PDF或一個PPT文件,而不是一個XLS等,但這些點是完全超出範圍了這個問題。)

如果您有其他跟進,請按照適當的場地禮儀和提出新問題:)

這將是罰款,如果該文件正在使用中,雖然application.displayalerts需要被禁用,以避免只讀對話。 – Zerk

謝謝David!該文件應該始終存在,所以唯一的問題是我會忘記日期。而不是做一個'退出小組​​',我怎麼能得到它回到輸入框? – sbagnato

使用'GoTo'語句或'While'循環。 –
