我有一个excel表单,其中包含大量在运行时添加的复选框。我想为每个复选框添加一个处理程序,这些复选框将在更改值时运行。我知道在其他版本的Visual Basic中我会使用AddHandler,但这在Excel VBA中不起作用。
举个例子,我想出了以下代码:
'This is in a class module called CheckboxHandler
Public WithEvents cb As MSForms.CheckBox
Private Sub cb_change()
MsgBox ("test")
end sub
而且,在我的用户表单中,我有这段代码:
With CreateObject("Scripting.Dictionary")
.....'Unrelated code omitted
'Variable Checkboxes
'Add Handler to checkboxes
Dim colCBHandlers As Collection
Set colCBHandlers = New Collection
Dim objHandler As CheckboxHandler
Dim i As Long
Dim chkBox As MSForms.CheckBox
For i = 1 To .count - 1
Set chkBox = Me.Controls.Add("Forms.Checkbox.1", "Checkbox" & i)
chkBox.Caption = .Keys()(i)
chkBox.VALUE = False
chkBox.Top = (chkBox.Height + 10) * (i - 1) + 55
chkBox.Left = 725
Set objHandler = New CheckboxHandler
Set objHandler.cb = chkBox
colCBHandlers.Add objHandler
Next i
End With
答案 0 :(得分:1)
colCBHandlers
将超出范围。
您需要将该集合声明为全局(在模块级别),以便在创建和填充后不会丢失。
