如何检查工作表是否存在？

Question

我想在特定路径的子文件夹中搜索具有特定名称的 Excel 书。 找到后，检查文档是否有特定的工作表。 如果没有，请插入另一个文件中的工作表并关闭文档。

我需要遍历特定路径中的每个文件夹（总共大约 300 个文件）。

Public strDestinationPath As String
Public strSearch As Variant    

Sub SearchFolders()

Range("B:M").ClearContents
Range("B1").Value = "Name"
Range("C1").Value = "Path"
Range("D1").Value = "Size (KB)"
Range("E1").Value = "DateLastModified"
Range("F1").Value = "Attributes"
Range("G1").Value = "DateCreated"
Range("H1").Value = "DateLastAccessed"
Range("I1").Value = "Drive"
Range("J1").Value = "ParentFolder"
Range("K1").Value = "ShortName"
Range("L1").Value = "ShortPath"
Range("M1").Value = "Type"
Range("B1").Select

Dim strPath As String
strPath = UserGetFolder & "\"

strSearch = InputBox("Enter Search Criteria (Case Sensitive)")

Dim OBJ As Object
Dim Folder As Object
Dim File As Object
Set OBJ = CreateObject("Scripting.FileSystemObject")
Set Folder = OBJ.GetFolder(strPath)

Call ListFiles(Folder)

Dim SubFolder As Object

For Each SubFolder In Folder.SubFolders
    Call ListFiles(SubFolder)
    Call GetSubFolders(SubFolder)
Next SubFolder

If Range("B2").Value = "" Then
    MsgBox "No Files Found", vbInformation
Else
End If

Range("B1").Select

End Sub


Private Sub ListFiles(ByRef Folder As Object)

For Each File In Folder.Files

    If InStr(File.Name, strSearch) <> 0 Then
    
        ActiveCell.Offset(1, 0).Select
        ActiveCell = File.Name
        ActiveCell.Offset(0, 1) = File.Path
        ActiveCell.Offset(0, 2) = (File.Size / 1024) 'IN KB
        ActiveCell.Offset(0, 3) = File.DateLastModified
        ActiveCell.Offset(0, 4) = File.Attributes
        ActiveCell.Offset(0, 5) = File.DateCreated
        ActiveCell.Offset(0, 6) = File.DateLastAccessed
        ActiveCell.Offset(0, 7) = File.Drive
        ActiveCell.Offset(0, 8) = File.ParentFolder
        ActiveCell.Offset(0, 9) = File.ShortName
        ActiveCell.Offset(0, 10) = File.ShortPath
        ActiveCell.Offset(0, 11) = File.Type
        
    Else
    End If
    
Next File

End Sub


Private Sub GetSubFolders(ByRef SubFolder As Object)

Dim FolderItem As Object

For Each FolderItem In SubFolder.SubFolders
    Call ListFiles(FolderItem)
    Call GetSubFolders(FolderItem)
    
    If File = Survey_Additional_Info Then
        Call WorksheetExists
        Call CopySheetToClosedWB
    Else
        'do nothing
    End If
    
Next FolderItem

End Sub


Function UserGetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    UserGetFolder = sItem
    Set fldr = Nothing
End Function


Function WorksheetExists(ByVal WorksheetName As String) As Boolean
    'Code to find sheet in a file - added by me not part of original

    Dim Sht As Worksheet

    For Each Sht In closedBook.Worksheets
        If Application.Proper(Time_Slots) = Application.Proper(Time_Slots) Then
            WorksheetExists = True
            Exit Function
        Else: Call CopySheetToClosedWB
            
        End If
    Next Sht
    WorksheetExists = False
End Function


Sub CopySheetToClosedWB() 'Copy Worksheet to a Closed Workbook
    Application.ScreenUpdating = False
 
    Set closedBook = Workbooks.Open("S:\Accordant\SUS\NewTimeSlotTab.xlsx")
    Sheets("Time_Slots").Copy Before:=closedBook.Sheets(Alternative_Locations)
    closedBook.Close SaveChanges:=True
 
    Application.ScreenUpdating = True
End Sub

我的代码最多

Call WorksheetExists

Answer 1

function WorksheetExists()不知道变量closedBook是什么。 该变量未传递，也不是Publlic。

编辑＃1：

通常，在为变量赋值之前，您不能使用变量。

例如在该行之前：

For Each Sht In closedBook.Worksheets

closedBook应该有一个Dim语句和一个Set语句。

Dim和Set应放置在包含For的 function 中。
