我在互联网上找到了很多资源几乎我想做什么,但并不完全。我有一个命名范围“daylist”。对于dayList中的每一天,我想在用户表单上创建一个按钮,该按钮将运行当天的宏。我能够add the buttons dynamically但不知道如何将daycell.text从命名范围,按钮,事件处理程序传递到宏:S继承我必须创建用户表单的代码:< / p>
Sub addLabel()
ReadingsLauncher.Show vbModeless
Dim theLabel As Object
Dim labelCounter As Long
Dim daycell As Range
Dim btn As CommandButton
Dim btnCaption As String
For Each daycell In Range("daylist")
btnCaption = daycell.Text
Set theLabel = ReadingsLauncher.Controls.Add("Forms.Label.1", btnCaption, True)
With theLabel
.Caption = btnCaption
.Left = 10
.Width = 50
.Top = 20 * labelCounter
End With
Set btn = ReadingsLauncher.Controls.Add("Forms.CommandButton.1", "runButton", True)
With btn
.Caption = "Run Macro for " & btnCaption
.Left = 80
.Width = 80
.Top = 20 * labelCounter
' .OnAction = "btnPressed"
End With
labelCounter = labelCounter + 1
Next daycell
End Sub
为了解决上述问题,我目前提示用户输入他们想要运行的日期(例如Day1)并将其传递给宏并且它有效:
Sub B45runJoinTransactionAndFMMS()
loadDayNumber = InputBox("Please type the day you would like to load:", Title:="Enter Day", Default:="Day1")
Call JoinTransactionAndFMMS(loadDayNumber)
End Sub
Sub JoinTransactionAndFMMS(loadDayNumber As String)
xDayNumber = loadDayNumber
Sheets(xDayNumber).Activate
-Do stuff
End Sub
因此,对于我的每个runButton,它需要显示daycell.text,并运行一个宏,该宏使用相同的文本作为参数来选择工作表来完成它的工作。
任何帮助都会很棒。我已经看到动态写入vba代码的响应,以处理宏,但我相信必须有一些通过传递参数可以更优雅地完成,只是不确定如何。非常感谢提前!

我知道您已经接受了一个适合您的解决方案,并且比下面的方法简单得多,但如果您感兴趣,这将是您问题的更直接的答案。
您需要创建一个类来处理按钮单击,因此每次单击该按钮时它都会使用该类中的事件,您只需要执行此操作一次,然后为每个按钮创建一个新实例。要阻止这些类超出范围并丢失,它们需要存储在类级别声明中。在下面我已经将你的代码移动了一点。
在类模块中(我称之为cButtonHandler)
Public WithEvents btn As MSForms.CommandButton
Private Sub btn_Click()
MsgBox btn.Caption
End Sub
使用事件,因为它允许您将大多数事件用于控件。我已将按钮生成代码移动到用户窗体中,如下所示:
Dim collBtns As Collection
Private Sub UserForm_Initialize()
Dim theLabel As Object
Dim labelCounter As Long
Dim daycell As Range
Dim btn As CommandButton
Dim btnCaption As String
'Create a variable of our events class
Dim btnH As cButtonHandler
'Create a new collection to hold the classes
Set collBtns = New Collection
For Each daycell In Range("daylist")
btnCaption = daycell.Text
Set theLabel = ReadingsLauncher.Controls.Add("Forms.Label.1", btnCaption, True)
With theLabel
.Caption = btnCaption
.Left = 10
.Width = 50
.Top = 20 * labelCounter
End With
Set btn = ReadingsLauncher.Controls.Add("Forms.CommandButton.1", "runButton", True)
With btn
.Caption = "Run Macro for " & btnCaption
.Left = 80
.Width = 80
.Top = 20 * labelCounter
'Create a new instance of our events class
Set btnH = New cButtonHandler
'Set the button we have created as the button in the class
Set btnH.btn = btn
'Add the class to the collection so it is not lost
'when this procedure finishes
collBtns.Add btnH
End With
labelCounter = labelCounter + 1
Next daycell
End Sub
然后我们可以从一个单独的例程中调用useform:
Sub addLabel()
ReadingsLauncher.Show vbModeless
End Sub
许多VBA书中都没有特别详细介绍VBA中的课程(通常你需要阅读VB6书籍以获得理解),但是一旦你理解了它们以及它们如何工作,它们就会变得非常有用:)
希望这有帮助

要引用集合中的对象,可以通过键或索引来完成。要使用密钥,您需要在将项目添加到集合时添加密钥,因此:
collBtns.Add btnH
会变成
collBtns.Add btnH, btnCaption
因此,密钥必须是唯一的。您可以参考如下:
'We refer to objects in a collection via the collection's key
'Or by it's place in the collection
'So either:
MsgBox collBtns("Monday").btn.Caption
'or:
MsgBox collBtns(1).btn.Caption
'We can then access it's properties and methods
'N.B you won't get any intellisense
collBtns("Monday").btn.Enabled = False
如果需要,您还可以在课程中添加其他属性/方法,例如:
Public WithEvents btn As MSForms.CommandButton
Private Sub btn_Click()
MsgBox btn.Caption
End Sub
Public Property Let Enabled(value As Boolean)
btn.Enabled = value
End Property
然后可以访问:
collBtns("Monday").Enabled = False
这有帮助吗?为了进一步阅读,我会指向Chip Pearson的网站,他在大多数主题上都有很棒的东西http://www.cpearson.com/excel/Events.aspx
请记住,VBA基于VB6,因此不是完全成熟的OO语言,例如,它不支持正常意义上的继承,只有接口继承
希望这会有所帮助:)

捕获点击工作表的示例。把它放在工作表模块中:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
' e.g., range(A1:E1) is clicked
If Not Application.Intersect(Target, Range("A1:E1")) Is Nothing Then
MsgBox "You clicked " & Target.Address
End If
End Sub
