如何在vba中将excel宏指定给命令按钮？

Question

我在Excel工作簿中编写了一个宏，该宏被分配给一个按钮。我现在在VBA中创建一个新表单，并尝试将相同的代码分配给命令按钮。 这是一个用于浏览指定URL并将信息提取到excel工作簿的代码。它适用于前10条记录，但后来，它在“For Each TRelement In TRelements”代码行中给出了错误“权限被拒绝”。

请帮我解决这个问题。

                maxOffSet = CInt(Split(Split(InputElement.getAttribute("onclick"), "Navigator(")(1), ")")(0))
            End If
        Next
        While offSet <= maxOffSet

                    i = 0
                    For Each Child In TRelement.ChildNodes
                        Sheet1.Range("A1").offSet(r, i).Value = Child.innerText
                        i = i + 1
                    Next
                    r = r + 1
                End If
            Next
            If offSet <= 10 Then
                Sheet1.Rows(1).Delete
                Sheet1.Rows(1).Delete
                r = r - 2
            End If
            If offSet > 10 Then
                Sheet1.Rows(offSet - 8).Delete
                Sheet1.Rows(offSet - 8).Delete
                Sheet1.Rows(offSet - 8).Delete
                r = r - 3
            End If
            IE.document.parentWindow.execScript "submitHTMLTableNavigator(" + CStr(offSet) + ");"

            'While .readyState <> READYSTATE_COMPLETE
                'DoEvents
            'Wend

            Do While IE.Busy
                Application.Wait DateAdd("s", 1, Now)
            Loop

        Sheet1.Range("A:F").WrapText = False
        IE.Quit
    Wend
    'End With
End Sub

我正在使用Excel 2010。

谢谢。
