Question

我找到了关于如何执行此操作的问题的可能答案here

然而，该问题的代码：

Sub UnCheckBoxes()
Dim ChkBox As CheckBox = Nothing
    ' to unchecked all
    For Each ChkBox As Object In Worksheets("Check sheet").Report_Checks.Controls
        If TypeOf xObject Is CheckBox Then
            ChkBox = xObject
            ChkBox.Checked = False
        End If
    Next
End Sub

产生＆＃39;编译错误：语法错误＆＃39;。任何帮助表示赞赏

Answer 1

根据我的评论。将代码切换为：

Sub UnCheckBoxes()
    Dim ChkBox As CheckBox = Nothing
    ' to unchecked all
    For Each xObject As Object In Worksheets("Check sheet").Report_Checks.Controls
        If TypeOf xObject Is CheckBox Then
            ChkBox = xObject
            ChkBox.Checked = False
        End If
    Next
End Sub

xObject对象用作循环类，以循环遍历Report_Checks中的所有控件。然后，If语句检查xObject是否为CheckBox类型。然后将ChkBox设置为xObject，以便您可以访问它的CheckBox属性并指定.Checked = False

Answer 2

这是一个解决方案，它使用OfType来消除每次检查对象类型的需要

For Each ChkBox As CheckBox In Worksheets("Check sheet").Report_Checks.Controls.OfType(Of CheckBox)
    ChkBox.Checked = False
Next
