Excel中 - 如何在Workbook_Open事件创建按钮 [英] Excel - How to create button upon Workbook_Open event

问题描述

我试图使一个Excel加载创建一个简单的按钮时，任何打开工作簿，但我发现

I'm trying to make an Excel Add-In to create a simple button when any workbook is opened, but I'm getting

对象变量或带块变量未设置

Object variable or With Block variable not set

我认为这正在发生的事情，因为在技术上不存在ActiveWorkbook'呢。

I think this is happening because technically there is no 'ActiveWorkbook' yet.

我想要做的第一件事是删除当前工作表上的任何按钮。然后，我要放置一个按钮。

First thing I want to do is delete any buttons currently on the sheet. Then I want to place a button.

任何人知道如何做到这一点？

Anyone know how to make that happen?

Private Sub Workbook_Open()
    ActiveWorkbook.ActiveSheet.Buttons.Delete
    Dim CommandButton As Button
    Set CommandButton = ActiveWorkbook.ActiveSheet.Buttons.Add(1200, 100, 200, 75)
    With CommandButton
        .OnAction = "Test_Press"
        .Caption = "Press for Test"
        .Name = "Test"
    End With
End Sub

然后我有一个私人小组TEST_ $ P $（PSS）来显示MSGBOX。未被虽然创建的按钮。

I then have a Private Sub Test_Press() to display a MsgBox. The button is not being created though.

推荐答案

幸得 HTTP ：//www.jkp-ads.com/Articles/FixLinks2UDF.asp

注意：我还有一个模块我没有低于张贴，里面有宏观的 Project_Count 的我绑在我按钮放置在工作簿只有在工作簿名称是TT_GO_ExceptionReport

Note: I have another module I didn't post below, which houses the macro Project_Count I tied to the button I place on the workbook only if the workbook name is TT_GO_ExceptionReport

我也有下载加载项，将它置于用户的插件文件夹，并安装一个VBScript。如果你想知道如何做到这一点，发表评论。

I also have a VBScript that downloads the Add-In, places it in the users addin folder, and installs it. If you want to know how to do that, leave a comment.

的ThisWorkbook

Option Explicit
    Private Sub Workbook_Open()
    ' Purpose   : Code run at opening of workbook
    '-------------------------------------------------------------------------    
    'Initialise the application
    InitApp
    modProcessWBOpen.TimesLooped = 0

    Application.OnTime Now + TimeValue("00:00:03"), "CheckIfBookOpened"
End Sub

的模块1 的名为 modInit
    显式的选项

Module 1 named modInit Option Explicit

'Create a module level object variable that will keep the instance of the
'event listener in memory (and hence alive)
Dim moAppEventHandler As cAppEvents

    Sub InitApp()
        'Create a new instance of cAppEvents class
        Set moAppEventHandler = New cAppEvents
        With moAppEventHandler
            'Tell it to listen to Excel's events
            Set .App = Application
        End With
    End Sub

的模块2 的名为 modProcessWBOpen
    显式的选项

Module 2 named modProcessWBOpen Option Explicit

'Counter to keep track of how many workbooks are open
Dim mlBookCount As Long

'Counter to check how many times we've looped
Private mlTimesLooped As Long

' Purpose   : When a new workbook is opened, this sub will be run.
' Called from: clsAppEvents.App_Workbook_Open and ThisWorkbook.Workbook_Open
'-------------------------------------------------------------------------
Sub ProcessNewBookOpened(oBk As Workbook)

    If oBk Is Nothing Then Exit Sub
    If oBk Is ThisWorkbook Then Exit Sub
    If oBk.IsInplace Then Exit Sub

    CountBooks

    'This checks to make sure the name of the new book matches what I 
    'want to place the button on
    If oBk.Name = "TT_GO_ExceptionReport.xlsm" Then
        Dim CommandButton As Button
        Set CommandButton = Workbooks("TT_GO_ExceptionReport.xlsm").Sheets(1).Buttons.Add(1200, 100, 200, 75)
        With CommandButton
            .OnAction = "Project_Count"
            .Caption = "Press for Simplified Overview"
            .Name = "Simplified Overview"
        End With
    End If
End Sub

Sub CountBooks()
    mlBookCount = Workbooks.Count
End Sub

Function BookAdded() As Boolean
    If mlBookCount <> Workbooks.Count Then
        BookAdded = True
        CountBooks
    End If
End Function

' Purpose   : Checks if a new workbook has been opened 
' (repeatedly until activeworkbook is not nothing)
'-------------------------------------------------------------------------
Sub CheckIfBookOpened()

    If BookAdded Then
        If ActiveWorkbook Is Nothing Then
            mlBookCount = 0
            TimesLooped = TimesLooped + 1
            'May be needed if Excel is opened from Internet explorer
            Application.Visible = True
            If TimesLooped < 20 Then
                Application.OnTime Now + TimeValue("00:00:01"), "CheckIfBookOpened"
            Else
                TimesLooped = 0
            End If
        Else
            ProcessNewBookOpened ActiveWorkbook
        End If
    End If
End Sub

Public Property Get TimesLooped() As Long
    TimesLooped = mlTimesLooped
End Property

Public Property Let TimesLooped(ByVal lTimesLooped As Long)
    mlTimesLooped = lTimesLooped
End Property

的类模块的名为 cAppEvents

' Purpose   : Handles Excel Application events
'-------------------------------------------------------------------------
Option Explicit

'This object variable will hold the object who's events we want to respond to
Public WithEvents App As Application

Private Sub App_WorkbookOpen(ByVal Wb As Workbook)

    'Make sure newly opened book is valid
    ProcessNewBookOpened Wb
End Sub

Private Sub Class_Terminate()
    Set App = Nothing
End Sub
