我正在使用带有SQL后端的Access应用程序。
我有一个人的表格,每个人都需要检查或取消选中不同的东西。表单上有以下字段和相应的控件:
没有选项(整数 - 布尔 - 复选框)
选项A(整数 - 布尔 - 复选框)
选项A金额(金钱)
选项B(整数 - 布尔 - 复选框)
选项B金额(金钱)
选项C(整数 - 布尔 - 复选框)
选项C金额(金钱)
选项D(整数 - 布尔 - 复选框)
选项D命令按钮(打开弹出窗体,选项类型下拉列表,输入多个值的金额)。
我担心的是,如果有人检查一个方框,它可能会与另一个复选框或货币字段发生冲突。
如果有人选中No Options,并且选中了其他选项之一,我必须取消选中。我还需要把他们相应的钱场分开0。如果有选项D"其他选项"记录,在链接表中,然后我需要删除这些,在我与用户确认后。我还想禁用选项A-D的复选框和money / command按钮控件。
如果我取消选中No Options,那么我需要启用所有这些。
您可以开始查看每次检查任何无选项或选项A - D时,我必须检查无选项的状态以及选项的相应金额,以确认用户想做出这个改变。
为此,我为更新前的无选项设置了以下代码:
Private Sub NoOptions_BeforeUpdate(Cancel As Integer)
Dim Msg, Style, Title
Dim delOLiensSQL
If Me.NoOptions = False Then
If (Me.OptionA = True Or Me.OptionB = True Or Me.OptionC = True Or Me.OptionD = True) Then
Msg = "You have chosen No Options, but one or more option is checked." & vbCrLf & _
"Choosing No Options will require removing all Lien amounts." & vbCrLf & _
"Would you like to change this Person to No Options?"
Style = vbYesNo
Title = "All Options Will Be Reset to 0 and False."
Response = MsgBox(Msg, Style, Title)
If Response = vbYes Then
If Nz(DLookup("ID", "tblPersonOtherOptionsD", "FKPerson = " & Me.ID), 0) Then
delOLiensSQL = "Delete From tblPersonOtherOptionsD Where FKPerson = " & Me.ID
DoCmd.RunSQL delOoptionssSQL, dbSeeChanges
End If
Me.OptionA = False
Me.OptionAAmount = 0
Me.OptionB = False
Me.OptionBAmount = 0
Me.OptionC = False
Me.OptionCAmount = 0
Me.OptionD = False
OptionsAllowPubFunc (False)
Else
Me.Undo
MsgBox "OK, we will leave everything as it is.", vbOKOnly, "Better Safe Than Sorry"
End If
Else
Me.NoOptions = True
End If
Else
Me.NoOptions = False
End If
End Sub
OptionsAllowPubFunc(False)是一个公共函数,如下所示:
Public Function PlaintiffLiensAllowed(Liens As Boolean)
Forms!frmPerson.OptionAAmount.Enabled = Liens
Forms!frmPerson.OptionBAmount.Enabled = Liens
Forms!frmPerson.OptionCAmount.Enabled = Liens
Forms!frmPerson.OptionDAmount.Enabled = Liens
End Function
我还为OptionA,OptionB,OptionC,OptionD设置了Before Update公共功能,如下所示:
Public Function ChangeAOption(OptionCheck As Control, OptionAmount As Control, OptionName As String)
Dim Msg, Style, Title
Dim Msg2, Style2, Title2
If OptionCheck = True Then
If Nz(OptionAmount, 0) > 0 Then
Msg = "There is a " & OptionName & " Option amount. Unchecking " & OptionName & " Option, will require the amount to be 0." & vbCrLf & _
"Would you like to uncheck " & OptionName & " Option and make the amount 0?"
Style = vbYesNo
Title = "Confirm No " & OptionName & " Option."
Response = MsgBox(Msg, Style, Title)
If Response = vbYes Then
OptionAmount = 0
OptionCheck = False
Else
OptionCheck.Undo
MsgBox "Ok, we will leave it as is.", vbOKOnly, "Better Safe Than Sorry."
End If
Else
OptionCheck = False
End If
Else
If Forms!frmPerson.NoOptions = True Then
Msg2 = "No Options is Checked. Checking " & OptionName & " Options will require no Options to be unchecked." & vbCrLf & _
"Would you like to uncheck no Options?"
Style2 = vbYesNo
Title2 = "Confirm No Options False."
Response2 = MsgBox(Msg2, Style2, Title2)
If Response2 = vbYes Then
OptionsAllowPubFunc (True)
Forms!frmPerson.NoOptions = False
OptionCheck = True
Else
OptionCheck = True
End If
Else
OptionCheck = True
End If
End Function
我正在对此进行测试,当我尝试选中No Options复选框时,将其从false更改为true,我收到运行时错误' -2147352567(80020009)':
将宏或函数设置为BeforeUpdate或ValidationRule属性 对于此字段阻止[人员应用程序]保存数据 在现场。
任何人都知道我做错了什么?有更简单的方法吗?
谢谢!!!
答案 0 :(得分:0)
根据我最近的经验,当触发Before Update事件时,它会在任何计算中使用字段的新值。所以我希望你想要开始像If
这样的主If Me.NoOptions = True Then
语句。
我也不相信你需要Else OptionCheck = True
之前的End If
位。
可能导致问题的原因是您已拨打OptionsAllowPubFunc
,但您在此问题中包含的功能实际上称为PlaintiffLiensAllowed
- 除非您有相同的功能OptionsAllowPubFunc,这个' ll会给你一个错误。
最后,我从未发现me.undo
在这种情况下特别有帮助,但是更新之前为您提供了一个 - 只需告诉它取消使用Cancel = True
(或任何内容)那不是0)并且它不会更新字段并退出子。
如果他们取消选中该框,您还可以添加一些内容来重新启用选项字段。
尝试将其作为:
运行Private Sub NoOptions_BeforeUpdate(Cancel As Integer)
Dim Msg As String, Style As VbMsgBoxStyle, Title As String
Dim Response As VbMsgBoxResult, delOLiensSQL As String
If Me.NoOptions = True Then
If (Me.OptionA = True Or Me.OptionB = True Or Me.OptionC = True Or Me.OptionD = True) Then
Msg = "You have chosen No Options, but one or more option is checked." & vbCrLf & _
"Choosing No Options will require removing all Lien amounts." & vbCrLf & _
"Would you like to change this Person to No Options?"
Style = vbYesNo
Title = "All Options Will Be Reset to 0 and False."
Response = MsgBox(Msg, Style, Title)
If Response = vbYes Then
If Nz(DLookup("ID", "tblPersonOtherOptionsD", "FKPerson = " & Me.ID), 0) Then
delOLiensSQL = "Delete From tblPersonOtherOptionsD Where FKPerson = " & Me.ID
DoCmd.RunSQL delOoptionssSQL, dbSeeChanges
End If
Me.OptionA = False
Me.OptionAAmount = 0
Me.OptionB = False
Me.OptionBAmount = 0
Me.OptionC = False
Me.OptionCAmount = 0
Me.OptionD = False
PlaintiffLiensAllowed(False)
Else
MsgBox "OK, we will leave everything as it is.", vbOKOnly, "Better Safe Than Sorry"
Cancel = True
End If
End If
Else
PlaintiffLiensAllowed(True)
End If
End Sub
