复制行时是否存在工作表的错误处理

Question

跟随我的帖子。如果单元格值与UserForm ComboBox列匹配，则复制到工作表。

我已经设法让代码工作起来，检查名称，然后移动到正确的表格。

我遇到的问题是检查床单是否存在。如果它在工作表和组合框中的第2列中找到匹配项，但没有该值的工作表，则会崩溃代码。

2. 一旦所有信息都被复制到相关的工作表中，我希望它显示一个消息框，告诉用户有多少行数据被复制到了相应的工作表。

在Jeeped的帮助下，我设法获得了将行复制到相关工作表的代码，如果工作表不存在，它就会创建它。我只需要解决上面的第二个问题。

Answer 1

尝试使用不存在的工作表对象会引发错误。如果您发现该错误并使用您正在查找的名称创建工作表，则可以Resume返回到引发错误的位置并继续处理。

Private Sub CommandButton7_Click()
    Dim i As Long, j As Long, lastG As Long, strWS As String, strMSG As String
    dim rngHDR as range, rngCPY aS range
    With Application
        .ScreenUpdating = False
        .EnableEvents = False
        .CutCopyMode = False
    End With
    On Error GoTo bm_Close_Out
    ' find last row
    lastG = Sheets("Global").Cells(Rows.Count, "Q").End(xlUp).Row
    For i = 3 To lastG
        lookupVal = Sheets("Global").Cells(i, "Q") ' value to find
        ' loop over values in "details"
        For j = 0 To Me.ComboBox2.ListCount - 1
            currVal = Me.ComboBox2.List(j, 2) ' value to match
            If lookupVal = currVal Then
                set rngHDR = Sheets("Global").Cells(1, "Q").EntireRow
                set rngCPY = Sheets("Global").Cells(i, "Q").EntireRow
                strWS = Me.ComboBox2.List(j, 1)
                On Error GoTo bm_Need_Worksheet  '<~~ if the worksheet in the next line does not exist, go make one
                With WorkSheets(strWS)
                     rngCPY .copy
                    .Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Insert shift:=xlDown
                End With
                exit for
            End If
        Next j
        if j >= Me.ComboBox2.ListCount then _
            strMSG = strMSG & "Not found: " & lookupVal & chr(10)
    Next i
GoTo bm_Close_Out      
bm_Need_Worksheet:
    On Error GoTo 0
    With Worksheets.Add(after:=Sheets(Sheets.Count))
        .Name = strWS
        'maybe make a header row here; watch out you do not lose your copy
        rngHDR.copy destination:=.cells(1, 1)
    End With
    On Error GoTo bm_Close_Out
    Resume
bm_Close_Out:
    With Application
        .ScreenUpdating = True
        .EnableEvents = True
        .CutCopyMode = False
    End With
    debug.print strMSG 
    'the next is NOT recommended as strMSG could possibly be VERY long
    'if cbool(len(strMSG)) then msgbox strMSG 
End Sub

有一个问题是，新工作表是否需要列标题标签行，但这应该很容易纠正。

Answer 2

您可以使用这样的函数：

Sub test_atame()
Dim Ws As Worksheet
Set Ws = Sheet_Exists(ThisWorkbook, "Sheet1")
Set Ws = Sheet_Exists(ActiveWorkbook, "Sheet1")
End Sub

以下是功能：

Public Function Sheet_Exists(aWorkBook As Workbook, Sheet_Name As String) As Worksheet
Dim Ws As Worksheet, _
    SExistS As Boolean
SExistS = False
For Each Ws In aWorkBook.Sheets
    If Ws.Name <> Sheet_Name Then
    Else
        SExistS = True
        Exit For
    End If
Next Ws
If SExistS Then
    Set Sheet_Exists = aWorkBook.Sheets(Sheet_Name)
Else
    Set Sheet_Exists = Nothing
    MsgBox "The sheet " & Sheet_Name & " wasn't found in " & aWorkBook.Name & vbCrLf & _
            "Break code to check and correct.", vbCritical + vbOKOnly
End If
End Function

Answer 3

也许是像这样的检查

Public Function SheetExists(ByVal Book As Workbook, ByVal SheetName As String) As Boolean
On Error Resume Next
Dim wsTest As Worksheet
Set wsTest = Book.Worksheets(SheetName)
If Not wsTest Is Nothing Then SheetExists = True
End Function
