使用VBA退出Excel会导致运行时错误424

Question

我一直在编写一个VBA宏，它在Excel中打开一个HTML文档（为了对它执行各种计算）。 Excel将在当前文件夹中搜索HTML文档。如果它找不到它，它将生成一个文件打开框，用户可以手动浏览到HTML文档的位置。到目前为止都很好。但是，如果用户选择取消（而不是选择文件），我希望Excel显示一条消息并退出。

生成消息但代码因以下错误而停止：

运行时错误'424'：需要对象。

这听起来不是太麻烦，但我一直在碰到一块砖墙，试图找出导致问题的原因。

似乎不起作用的子是：

Sub ExitWithoutPrompt()

MsgBox "You failed to select a file, therefore Excel will now close.  Please refer to the readme file."
Excel.Application.DisplayAlerts = False
Excel.Application.Quit

End Sub

我正在使用MS Excel 2002，但我渴望解决方案能够处理尽可能多的Excel变体。

感谢我在哪里出错了。顺便说一下，我是一个完整的新手，所以如果可能的话，请为我提供任何指导，啰嗦......

因为它可能在下面使用（有使这篇文章变得笨拙的风险）是我在宏中使用的另外两个潜艇：

第一分：

Sub Endurance()

Call OpenHTML

Range("G27").Value = "Category"
Range("G28").Value = "Meat"
Range("G29").Value = "Veg"
Range("G30").Value = "PRP"
Range("F27").Value = "Fleet"
Range("E27").Value = "Consumption"

Range("E32").Value = "Endurance"

Range("E33").Value = "Lowest Category"
Range("E34").Value = "Fleet"
Range("E35").Value = "Consumption"

Range("E27, F27, G27, E32").Font.Bold = True
Range("F28").Value = WorksheetFunction.Sum(Range("E8,E9,E11,E14,E21"))
Range("E28").Value = WorksheetFunction.Sum(Range("G8,G9,G11,G14,G21"))
Range("F29").Value = WorksheetFunction.Sum(Range("E10,E16"))
Range("E29").Value = WorksheetFunction.Sum(Range("G10,G16"))
Range("F30").Value = WorksheetFunction.Sum(Range("E20,E22"))
Range("E30").Value = WorksheetFunction.Sum(Range("G20,G22"))

Columns("E:F").EntireColumn.AutoFit

Range("G28:G30, E27, F27, G27, G33").Select
    With Selection
        .HorizontalAlignment = xlRight
    End With

Range("E27:G30, E32:G35").Select
    Selection.Borders(xlDiagonalDown).LineStyle = xlNone
    Selection.Borders(xlDiagonalUp).LineStyle = xlNone
    With Selection.Borders(xlEdgeLeft)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    With Selection.Borders(xlEdgeTop)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    With Selection.Borders(xlEdgeBottom)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    With Selection.Borders(xlEdgeRight)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    Selection.Borders(xlInsideVertical).LineStyle = xlNone
    Selection.Borders(xlInsideHorizontal).LineStyle = xlNone


Dim Endurance As Double
Endurance = WorksheetFunction.Min(Range("F28:F30"))
Range("G34").Value = WorksheetFunction.RoundDown(Endurance, 0)

Endurance = WorksheetFunction.Min(Range("E28:E30"))
Range("G35").Value = WorksheetFunction.RoundDown(Endurance, 0)

Range("G33").Value = Endurance

Dim LowCat As String

LowCat = WorksheetFunction.VLookup(Endurance, Range("E28:G30"), 3, False)
Range("G33").Value = LowCat

ActiveSheet.PageSetup.PrintArea = "$A$1:$G$35"
ActiveSheet.PageSetup.Orientation = xlLandscape

Range("G36").Select

If MsgBox("Print endurance statement?", vbYesNo + vbDefaultButton2, "Print endurance") = vbYes Then
    ActiveWindow.SelectedSheets.PrintOut Copies:=1
    Else
    Range("G36").Select
    End If


End Sub

第二个子：

Sub OpenHTML()

On Error GoTo MissingFile

Workbooks.Open FileName:=ThisWorkbook.Path & "\TRICAT Endurance Summary.html"


Exit Sub

MissingFile:

Dim Finfo As String
Dim FilterIndex As Integer
Dim Title As String
Dim FileName As Variant

' Set up list of file filters
Finfo = "HTML Files (*.html),*.html," & _
        "All Files (*.*),*.*,"

' Display *.html by default
    FilterIndex = 1

' Set the dialog box caption
Title = "Select TRICAT Endurance Summary"

' Get the filename
FileName = Application.GetOpenFilename(FInfor, FilterIndex, Title)

' Handle Return info from dialog box
If FileName = False Then
    Call ExitWithoutPrompt
    Else
    MsgBox "You selected" & FileName
    Workbooks.Open FileName

End If

End Sub

如果你已经走到这一步，感谢阅读......

Answer 1

将 ActiveWorkbook.Close 的调用添加到 ExitWithoutPrompt ：

Sub ExitWithoutPrompt()
    MsgBox "You failed to select a file, therefore Excel will now close.  Please refer to the readme file."
    Excel.Application.DisplayAlerts = False
    Excel.Application.Quit
    ActiveWorkbook.Close False
End Sub

这适用于我在Excel 2003下。

出于某种原因，调用 Application.Quit 和 ActiveWorkbook.Close 的顺序非常重要。反直觉地，至少在我看来，如果你在 Application.Quit 之前调用 ActiveWorkbook.Close ，你仍然会得到错误。
