Excel VBA - 在文件夹中循环文件和使用子过程时错误处理

Question

我创建了一个宏来遍历文件夹中的文件并通过 2 个子过程（其中一个子过程也调用其他子过程）运行一些操作。 在某些情况下，文件没有正确的格式或导致任何子过程失败的任何其他错误。 我想添加错误处理，以便它跳过文件，但它将文件的名称保存在 txt 或最后的 msg 框中，显示哪些文件未处理。 我对循环中的错误处理不熟悉，所以我不确定如何做到这一点。 任何帮助将非常感激。

Dim folderName As String, eApp As Excel.Application, fileName As String
Dim wb As Workbook, ws As Worksheet, currWs As Worksheet, currWb As Workbook
Dim fDialog As Object: Set fDialog = Application.FileDialog(msoFileDialogFolderPicker)
Set currWb = ActiveWorkbook: Set currWs = ActiveSheet
Dim lcolPS As Integer
Dim lcolTC As Integer
Dim lcolRTD As Integer
Dim NumberPS As Integer
Dim TC_Number As Integer
Dim RTD_Number As Integer
Dim fileName2 As String


'Select folder in which all files are stored
fDialog.Title = "Select a folder"
fDialog.InitialFileName = currWb.Path
If fDialog.Show = -1 Then
  folderName = fDialog.SelectedItems(1)
End If

 'Create a separate Excel process that is invisibile
Set eApp = New Excel.Application:  eApp.Visible = True
eApp.DisplayAlerts = False
eApp.ScreenUpdating = False

'Search for all files in folder [replace *.* with your pattern e.g. *.xlsx]
fileName = Dir(folderName & "\*Steady*.xlsx")
'fileName = "C:\Users\mconejoh\OneDrive - Intel Corporation\Documents\Lidded BGA\ETB4_noTS_lid_5W_CPU_heavy.xlsx"
Do While fileName <> ""
    'Update status bar to indicate progress
    Application.StatusBar = "Processing " & folderName & "\" & fileName
    Set wb = eApp.Workbooks.Open(folderName & "\" & fileName)
    eApp.DisplayAlerts = False
    eApp.ScreenUpdating = False
    
    'Get the PS, RTD and TC number:
    lcolPS = wb.Worksheets("Power").Cells(1, Columns.Count).End(xlToLeft).Column
    NumberPS = (lcolPS - 1) / 3
    lcolTC = wb.Worksheets("Thermocouples").Cells(1, Columns.Count).End(xlToLeft).Column
    TC_Number = lcolTC - 1
    lcolRTD = wb.Worksheets("RTDS").Cells(1, Columns.Count).End(xlToLeft).Column
    RTD_Number = lcolRTD - 1
    
    'Run each subprocedure

    Call RTS_powerSheet(wb, NumberPS)
    Call PL1_only(wb, RTD_Number, TC_Number, NumberPS)
    wb.Close SaveChanges:=True
    'Close opened worbook w saving, change as needed
    fileName = Dir()
    
    eApp.DisplayAlerts = True
    eApp.ScreenUpdating = True

Loop
eApp.Quit
Set eApp = Nothing
'Clear statusbar and notify of macro completion
Application.StatusBar = ""
MsgBox "Completed executing macro on all workbooks"

您将您的潜艇重写为函数。 然后一个结构如何收集潜艇失败的所有文件可能看起来像这样

    Sub fileLoop()
    
        Dim Foldername, fileName
        
        Dim colProblem As New Collection
     
        fileName = Dir(Foldername & "\*Steady*.xlsx")
        Do While fileName <> ""
    
            If Not Dosth(fileName) Then
                colProblem.Add fileName
            End If
    
            fileName = Dir()
    
        Loop
    
    End Sub
    
    Function Dosth(fileName) As Boolean
    
        On Error GoTo EH
        ' ... Code here
        
        ' In case everything went fine
        ' function did its job
        Dosth = True
        
        Exit Function

     EH:

        Dosth = false

    End Function
