是否可以通过编程方式单击关闭按钮

如何解决是否可以通过编程方式单击关闭按钮

我在Access中使用窗体作为对话框，并且试图弄清楚如何以编程方式关闭它。 our-button在这里不起作用，因为它以DoCmd.Close开头。

是否有一种方法可以调用用户单击关闭按钮时触发的同一事件？ 如果没有，该如何以编程方式关闭表单？

编辑：

为了澄清，这是我的表格：

这是事件：

acDialog

（代码中不包含子代码，只是为了说明问题）

解决方法

如果您要查找表单超时，可以研究该函数：

' Opens a modal form in non-dialogue mode to prevent dialogue borders to be displayed
' while simulating dialogue behaviour using Sleep.

' If TimeOut is negative,zero,or missing:
'   Form FormName waits forever.
' If TimeOut is positive:
'   Form FormName exits after TimeOut milliseconds.

Public Function OpenFormDialog( _
    ByVal FormName As String,_
    Optional ByVal TimeOut As Long,_
    Optional ByVal OpenArgs As Variant = Null) _
    As Boolean
        
    Const SecondsPerDay     As Single = 86400
    
    Dim LaunchTime          As Date
    Dim CurrentTime         As Date
    Dim TimedOut            As Boolean
    Dim Index               As Integer
    Dim FormExists          As Boolean
    
    ' Check that form FormName exists.
    For Index = 0 To CurrentProject.AllForms.Count - 1
        If CurrentProject.AllForms(Index).Name = FormName Then
            FormExists = True
            Exit For
        End If
    Next
    If FormExists = True Then
        If CurrentProject.AllForms(FormName).IsLoaded = True Then
            ' Don't reopen the form should it already be loaded.
        Else
            ' Open modal form in non-dialogue mode to prevent dialogue borders to be displayed.
            DoCmd.OpenForm FormName,acNormal,acWindowNormal,OpenArgs
        End If
        
        ' Record launch time and current time with 1/18 second resolution.
        LaunchTime = Date + CDate(Timer / SecondsPerDay)
        Do While CurrentProject.AllForms(FormName).IsLoaded
            ' Form FormName is open.
            ' Bring form to front; it may hide behind a popup form.
            DoCmd.SelectObject acForm,FormName
            ' Make sure form and form actions are rendered.
            DoEvents
        
            ' Halt Access for 1/20 second.
            ' This will typically cause a CPU load less than 1%.
            ' Looping faster will raise CPU load dramatically.
            Sleep 50
            If TimeOut > 0 Then
                ' Check for time-out.
                CurrentTime = Date + CDate(Timer / SecondsPerDay)
                If (CurrentTime - LaunchTime) * SecondsPerDay > TimeOut / 1000 Then
                    ' Time-out reached.
                    ' Close form FormName and exit.
                    DoCmd.Close acForm,FormName,acSaveNo
                    TimedOut = True
                    Exit Do
                End If
            End If
        Loop
        ' At this point,user or time-out has closed form FormName.
    End If
    
    ' Return True if the form was not found or was closed by user interaction.
    OpenFormDialog = Not TimedOut

End Function

它取自我的项目VBA.ModernBox中的模块 ModernBox.bas 。

对于“关闭/取消”按钮，请始终使用

DoCmd.Close acForm,Me.Name

即使您重命名表单，也可以使用Me.Name。

您可能要添加

DoCmd.Close acForm,Me.Name,acSaveNo

避免用户设置的过滤器或排序顺序与表单一起保存。
