我有一个Excel电子表格,它将单元格的值设置为组中复选框的数量。我想为每个看起来像这样的宏分配一个宏:
Sub clickedBox()
If thisBox(or however you would do it).Checked = True Then
Range("D9").Value = Range("D9").Value + 1
Else
Range("D9").Value = Range("D9").Value - 1
End If
End Sub
单元格默认为0,所有框默认为未选中。这样一来,勾选一个方框就可以计算出来,然后将其扣掉,将其击倒,并且它永远不会低于零或高于方框的数量。
我意识到我也应该这样做,以便当复选框的状态发生变化时宏不会触发,不仅仅是在点击它时,我还要确保这是可行的。
有没有办法让复选框像这样引用?

这取决于您是否与ActiveX控件或表单控件绑定。两者都可以工作,任何一条路径都可能指示如何清楚地实现它。
使用ActiveX控件(复选框):
您可以使用两种方法为ActiveX控件编写“点击处理程序”。第一个是为每个控件硬编码一个公共子:
控制Thisworkbook.Sheets("Sheet1")
:CheckBox1
Sheet1
中的代码:
Private groupCheckBoxCount As Integer
Private Sub CheckBox1_Click()
Debug.Print "Control on " & Me.Name & " is now " & Me.CheckBox1.Value
RegisterCheckedValue Me.CheckBox1.Value
End Sub
Private Sub RegisterCheckedValue(cbVal As Boolean)
If cbVal = True Then
Range("CheckBoxCount") = Range("CheckBoxCount") + 1 'choose to store on the sheet
groupCheckBoxCount = groupCheckBoxCount + 1 'or in a variable
Else
Range("CheckBoxCount") = Range("CheckBoxCount") - 1
groupCheckBoxCount = groupCheckBoxCount - 1
End If
End Sub
然后,如果你有10个复选框,你将有10个CheckBox(x)_Click
个子,每个子项专门绑定到一个ActiveX控件。这些点击处理程序中的每一个都可以增加或减少存储在工作表单元格中(或模块私有变量中)的计数器。
第二个选项是创建一个类模块,您可以为任意数量的CheckBox实例化。
类模块MyCheckBoxClass
的代码
Dim WithEvents cbControl As MSForms.CheckBox
Private controlName As String
Public Sub cbControl_Click()
Debug.Print controlName & " is now " & cbControl.Value
If cbControl.Value = True Then
Range("CheckBoxCount") = Range("CheckBoxCount") + 1 'choose to store on the sheet
groupCheckBoxCount = groupCheckBoxCount + 1 'or in a variable
Else
Range("CheckBoxCount") = Range("CheckBoxCount") - 1
groupCheckBoxCount = groupCheckBoxCount - 1
End If
End Sub
Public Sub Attach(newCB As MSForms.CheckBox, newName As String)
Set cbControl = newCB
controlName = newName
End Sub
Private Sub Class_Initialize()
controlName = ""
End Sub
常规代码模块中的代码:
Public groupClickCount As Integer
Private cbCollection As Collection
Public Sub SetUpControlsOnce()
Dim thisCB As MyCheckBoxClass
Dim ctl As OLEObject
Dim cbControl As MSForms.CheckBox
If cbCollection Is Nothing Then
Set cbCollection = New Collection
End If
For Each ctl In ThisWorkbook.Sheets("Sheet1").OLEObjects
If TypeName(ctl.Object) = "CheckBox" Then
'--- this is an ActiveX CheckBox
Set thisCB = New MyCheckBoxClass
thisCB.Attach ctl.Object, ctl.name
cbCollection.Add thisCB
End If
Next ctl
End Sub
使用表单控件(复选框):
虽然有多种方法可以捕获表单复选框的click事件,但最简单的方法是将组中的所有复选框连接到单个宏:
Public groupClickCount As Integer
Public Sub cbControl_Click()
'--- loop through all the controls on the form and filter for
' only checkboxes, then count up how many are checked
Dim ctl As Shape
Dim checkCount As Integer
checkCount = 0
For Each ctl In ActiveSheet.Shapes
If ctl.Type = msoFormControl Then
On Error Resume Next
If ctl.ControlFormat = xlCheckBox Then
If ctl.ControlFormat.Value = 1 Then
checkCount = checkCount + 1
Else
checkCount = checkCount - 1
End If
End If
End If
Next ctl
Range("CheckBoxCount") = checkCount 'choose to store on the sheet
groupClickCount = checkCount 'or in a variable
End Sub
根据您的需求以及您希望如何跟踪复选框,这两种解决方案都可以通过多种方式进行调整。
