【问题描述】:
我正在尝试创建一个类模块,当有人单击我表单中的 60 个文本框之一时,该模块将充当全局处理程序。文本框代表一周的考勤卡,显示信息为打卡、打卡、午餐开始、结束、持续时间、一周 7 天每天的总小时数。当有人在一天内单击任何一个框时,所有框都将解锁并启用,以便用户可以编辑其中的信息。
在网上搜索全局点击事件的解决方案后,我发现我可以创建一个类模块来处理事件,而无需为调用单独函数来处理事件的每个文本框创建点击事件。我遇到的问题是我的类模块似乎没有处理我的事件,并且想知道是否有人可以建议我的问题的解决方案。仅供参考,我所有的文本框都被锁定和禁用以防止数据损坏。以下是我的代码:
''# Class module
Option Compare Database
Option Explicit
Public WithEvents TC_txtbox As TextBox
''# Set the textbox so that its events will be handled
Public Property Set TextBox(ByVal m_tcTxtBox As TextBox)
TC_txtbox = m_tcTxtBox
End Property
''# Handle and onClick event of the
Private Sub TC_txtbox_Click()
''# Find out the controls that where clikck
Debug.Print Form_TimeCard.ActiveControl.Name
Dim ctl As Control
For Each ctl In access.Forms.Controls
Debug.Print ctl.Name
Next ctl
End Sub
表格代码
Option Compare Database
Option Explicit
''# Global Variables
Public clk_inout As Boolean
Public settings
Public weekDict
Public weekOf As Variant
Public curDay As Variant
Public txtBxCollection As Collection
''# Event Handler for when the form opens
Private Sub Form_Open(Cancel As Integer)
''# Configure varaibles
Me.TimerInterval = 60000 ''# 10 sec Interval
weekOf = getFirstDayofWeek(Date)
curDay = Date
Set weekDict = CreateObject("Scripting.Dictionary")
Set settings = CreateObject("Scripting.Dictionary")
Set txtBxCollection = New Collection
''# Load Time Card Data
Call initSettings
''# Debug.Print "Work Day Goal " & settings.Item("Work_day_goal_hrs")
Call initDict
Call initTextBoxEventHandler
Debug.Print "Collection count " & txtBxCollection.Count
Call loadDates(Date)
Call clearDay
Call selectDay(Date)
Call loadWeeksData(weekOf)
Dim ctl As Control
Set ctl = weekDict.Item(Weekday(curDay)).Item("In")
If IsDate(ctl.Value) And (Not ctl.Value = "") Then
Me.but_clk_inout.Caption = "Clock Out"
Me.but_lunch.Visible = True
clk_inout = False
Else
Me.but_clk_inout.Caption = "Clock In"
Me.but_lunch.Visible = False
clk_inout = True
End If
''# Debug.Print "Work Day Goal " & settings.Item("Salary")
End Sub
Public Sub initTextBoxEventHandler()
Dim eventHandler As TextBoxEventHandler
Set eventHandler = New TextBoxEventHandler
Debug.Print "Collection count " & txtBxCollection.Count
Set eventHandler.TextBox = Me.txt_F_in
txtBxCollection.Add eventHandler
Debug.Print "Collection count " & txtBxCollection.Count
End Sub

我在设置文本框的类模块中发现了我的问题,我忘记添加“TC_txtbox.OnClick = “[Event Procedure]”” VBA 不会触发我的自定义偶数处理程序如果您要处理的事件的属性中未声明 [Event Procedure],则扩展文本框
