userform文本框如果保持空白则起作用

Question

我创建了一个useform，它帮助我从B列或C列更改活动工作表或所有工作表的列宽和行高（基于Frame3中的选择选项）（基于Frame2中的选择选项）基于textbox1和textbox2中输入的文本。 我已经使用了userform供您参考。

此代码工作正常，但是如果我只需要更改列宽而不是行高，那么当我键入列宽并将行高保持为空时，它会在下面提到的行上给出错误：  Selection.Cells.RowHeight = Me.TextBox2.Value

请告诉我如何修改我的代码，即使任何文本框值留空（即如果我只想更改列宽并按原样保持行高）那么它不应该给我错误。

Userform代码：

Dim exworkb As Workbook
Dim xlwksht As Worksheet
Dim lastrow1 As Long
Dim lastcolumn1 As Long
Dim firstrowDB As Long
Dim Z As Integer
Dim ShtNames() As String

Private Sub CommandButton1_Click()

If Me.OptionButton3.Value = True Then
    If Me.OptionButton1.Value = True Then
        Call rowcolactivesheetb
        Selection.Cells.RowHeight = Me.TextBox2.Value
        Selection.Cells.ColumnWidth = Me.TextBox1.Value
    ElseIf Me.OptionButton2.Value = True Then
        ReDim ShtNames(1 To ActiveWorkbook.Sheets.Count)
        For Z = 1 To Sheets.Count
            ShtNames(Z) = Sheets(Z).Name
            If ShtNames(Z) <> "Trans_Letter" And ShtNames(Z) <> "Cover" And ShtNames(Z) <> "Abbreviations" And InStr(ShtNames(Z), "_Index") = 0 Then
                Sheets(Z).Select
                lastrow1 = Sheets(Z).Cells(Rows.Count, "A").End(xlUp).Row
                lastcolumn1 = Sheets(Z).Cells(1, Columns.Count).End(xlToLeft).Column
                ActiveWorkbook.Sheets(Z).Range(Sheets(Z).Cells(1, 2), Sheets(Z).Cells(lastrow1, lastcolumn1)).Select
                Selection.Cells.RowHeight = Me.TextBox2.Value
                Selection.Cells.ColumnWidth = Me.TextBox1.Value
            End If
        Next Z
    End If
End If

If Me.OptionButton4.Value = True Then
    If Me.OptionButton1.Value = True Then
        Call rowcolactivesheetc
        Selection.Cells.RowHeight = Me.TextBox2.Value
        Selection.Cells.ColumnWidth = Me.TextBox1.Value
    ElseIf Me.OptionButton2.Value = True Then
        ReDim ShtNames(1 To ActiveWorkbook.Sheets.Count)
        For Z = 1 To Sheets.Count
            ShtNames(Z) = Sheets(Z).Name
            Sheets(Z).Select
            If ShtNames(Z) <> "Trans_Letter" And ShtNames(Z) <> "Cover" And ShtNames(Z) <> "Abbreviations" And InStr(ShtNames(Z), "_Index") = 0 Then
                lastrow1 = Sheets(Z).Cells(Rows.Count, "A").End(xlUp).Row
                lastcolumn1 = Sheets(Z).Cells(1, Columns.Count).End(xlToLeft).Column
                ActiveWorkbook.Sheets(Z).Range(Sheets(Z).Cells(1, 3), Sheets(Z).Cells(lastrow1, lastcolumn1)).Select
                Selection.Cells.RowHeight = Me.TextBox2.Value
                Selection.Cells.ColumnWidth = Me.TextBox1.Value
            End If
        Next Z
    End If
End If

End Sub

Private Sub CommandButton2_Click()
