VBA를 사용하여 파일이 있는지 확인하십시오.

Sub test()

thesentence = InputBox("Type the filename with full extension", "Raw Data File")

Range("A1").Value = thesentence

If Dir("thesentence") <> "" Then
    MsgBox "File exists."
Else
    MsgBox "File doesn't exist."
End If

End Sub

입력 상자에서 텍스트 값을 가져 오면 작동하지 않습니다. 그러나 If "the sentence"에서 제거 Dir()하고 코드의 실제 이름으로 바꾸면 작동합니다. 누군가 도울 수 있습니까?

코드가 포함되어 참고 Dir("thesentence")해야한다 Dir(thesentence).

이 코드를 변경하십시오

Sub test()

thesentence = InputBox("Type the filename with full extension", "Raw Data File")

Range("A1").Value = thesentence

If Dir(thesentence) <> "" Then
    MsgBox "File exists."
Else
    MsgBox "File doesn't exist."
End If

End Sub

Office FileDialog개체를 사용하여 사용자가 파일 시스템에서 파일을 선택하도록합니다. VB 프로젝트 또는 VBA 편집기에서 참조를 추가 Microsoft Office Library하고 도움말을보십시오. 이것은 사람들이 완전한 길로 들어가는 것보다 훨씬 낫습니다.

다음은 msoFileDialogFilePicker사용자가 여러 파일을 선택할 수 있도록 사용하는 예 입니다. 당신은 또한 사용할 수 있습니다 msoFileDialogOpen.

'Note: this is Excel VBA code
Public Sub LogReader()
    Dim Pos As Long
    Dim Dialog As Office.FileDialog
    Set Dialog = Application.FileDialog(msoFileDialogFilePicker)

    With Dialog
        .AllowMultiSelect = True
        .ButtonName = "C&onvert"
        .Filters.Clear
        .Filters.Add "Log Files", "*.log", 1
        .Title = "Convert Logs to Excel Files"
        .InitialFileName = "C:\InitialPath\"
        .InitialView = msoFileDialogViewList

        If .Show Then
            For Pos = 1 To .SelectedItems.Count
                LogRead .SelectedItems.Item(Pos) ' process each file
            Next
        End If
    End With
End Sub

많은 옵션이 있으므로 가능한 모든 것을 이해하려면 전체 도움말 파일을 확인해야합니다. Office 2007 FileDialog 개체로 시작할 수 있습니다 (물론 사용중인 버전에 대한 올바른 도움말을 찾아야합니다).

@UberNubIsTrue에서 fileExists 수정 :

Function fileExists(s_directory As String, s_fileName As String) As Boolean

  Dim obj_fso As Object, obj_dir As Object, obj_file As Object
  Dim ret As Boolean
   Set obj_fso = CreateObject("Scripting.FileSystemObject")
   Set obj_dir = obj_fso.GetFolder(s_directory)
   ret = False
   For Each obj_file In obj_dir.Files
     If obj_fso.fileExists(s_directory & "\" & s_fileName) = True Then
        ret = True
        Exit For
      End If
   Next

   Set obj_fso = Nothing
   Set obj_dir = Nothing
   fileExists = ret

 End Function

편집 : 단축 버전

' Check if a file exists
Function fileExists(s_directory As String, s_fileName As String) As Boolean

    Dim obj_fso As Object

    Set obj_fso = CreateObject("Scripting.FileSystemObject")
    fileExists = obj_fso.fileExists(s_directory & "\" & s_fileName)

End Function

그 음성 표시를 제거하십시오

Sub test()

Dim thesentence As String

thesentence = InputBox("Type the filename with full extension", "Raw Data File")

Range("A1").Value = thesentence

If Dir(thesentence) <> "" Then
    MsgBox "File exists."
Else
    MsgBox "File doesn't exist."
End If

End Sub

이것은 내가 좋아하는 것입니다.

Option Explicit

    ExistsAndClosedOrReadOnly = 0
    ExistsAndOpenSoBlocked = 1
    NotExists = 2
End Enum


Function IsFileReadOnlyOpen(FileName As String) As IsFileOpenStatus

With New FileSystemObject
    If Not .FileExists(FileName) Then
        IsFileReadOnlyOpen = 2  '  NotExists = 2
        Exit Function 'Or not - I don't know if you want to create the file or exit in that case.
    End If

Function FileExists(fullFileName As String) As Boolean
    FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End Function

내 사이트에서 거의 잘 작동합니다. 빈 문자열 ""로 호출하면 Dir는 " connection.odc "!! 여러분이 결과를 공유 할 수 있다면 좋을 것입니다.

어쨌든, 나는 이것을 좋아합니다 :

Function FileExists(fullFileName As String) As Boolean
  If fullFileName = "" Then
    FileExists = False
  Else
    FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
  End If
End Function

귀하의 코드에 어떤 문제가 있는지는 확실하지 않지만 온라인에서 찾은이 함수 (주석의 URL)를 사용하여 파일이 있는지 확인합니다.

Private Function File_Exists(ByVal sPathName As String, Optional Directory As Boolean) As Boolean
    'Code from internet: http://vbadud.blogspot.com/2007/04/vba-function-to-check-file-existence.html
    'Returns True if the passed sPathName exist
    'Otherwise returns False
    On Error Resume Next
    If sPathName <> "" Then

        If IsMissing(Directory) Or Directory = False Then

            File_Exists = (Dir$(sPathName) <> "")
        Else

            File_Exists = (Dir$(sPathName, vbDirectory) <> "")
        End If

    End If
End Function

Function FileExists(fullFileName As String) As Boolean
    FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End Function

Very old post, but since it helped me after I made some modifications, I thought I'd share. If you're checking to see if a directory exists, you'll want to add the vbDirectory argument to the Dir function, otherwise you'll return 0 each time. (Edit: this was in response to Roy's answer, but I accidentally made it a regular answer.)

Private Function FileExists(fullFileName As String) As Boolean
    FileExists = Len(Dir(fullFileName, vbDirectory)) > 0
End Function

---

based on other answers here I'd like to share my one-liners that should work for dirs and files:

• Len(Dir(path)) > 0 or Or Len(Dir(path, vbDirectory)) > 0  'version 1 - ... <> "" should be more inefficient generally
  

  • (just Len(Dir(path)) did not work for directories (Excel 2010 / Win7))

• CreateObject("Scripting.FileSystemObject").FileExists(path)  'version 2 - could be faster sometimes, but only works for files (tested on Excel 2010/Win7)
  

as PathExists(path) function:

Public Function PathExists(path As String) As Boolean
    PathExists = Len(Dir(path)) > 0 Or Len(Dir(path, vbDirectory)) > 0
End Function
