Access 2016 Switchboard 将宏转换为 vba

Question

在 Access 2016 Switchboard 上，我将表单后面的宏转换为 VBA，但无法编译。我发现的创可贴解决方案是将 .Value 添加到 TempVars.Add "CurrentItemNumber", ItemNumber 并更改两个实例Call Argument & "()" 到 Call Eval(Argument & "()")。这解决了编译错误。

然后我向总机添加了另一个按钮 "Reports Menu"，但是当我点击新按钮时出现此错误。

当我单击“调试”时，它会突出显示此行 TempVars.Add "SwitchboardID"，参数。当我将 .Value 添加到此行的末尾时 TempVars.Add "SwitchboardID", Argument.Value 它解决了断点问题和新按钮可以使用，但现在报告菜单无法正确填写。

我可以单击 Return 到主菜单返回主菜单，主菜单上的所有其他按钮都可以正常工作，除了新的报告菜单按钮。

这是交换机背后的代码...

Answer 1

对您的代码的一些批评：

Call Eval(Argument & "()") 没有任何意义。 Call 是多余的； Eval(Argument & "()")才是真正调用Argument中的函数名。请尝试 Application.Run Me.Argument.Value。
您应该在代码中完全指定所有控件值。示例：Me.Command.Value、Me.Argument.Value、Me.ItemNumber.Value 等
而不是 DoCmd.SetProperty "Label1", acPropertyCaption, "caption"，使用：Me.Lable1.Caption = "caption"
在任何情况下，都不需要使用与 Label1 相同的 DLookup 函数来设置 Lable2。只需使用 Me.Label2.Caption = Me.Label1.Caption
而不是TempVars.Add "SwitchboardID", Argument，写成TempVars("SwitchboardID") = Me.Argument.Value

这将帮助您实现目标，但我不能保证这会解决您的问题。您将不得不使用传统的调试方法找出其他可能出错的地方，并修复它。

我非常感谢您的回复，但由于时间限制，我放弃了尝试修复由 Access 2016（当它转换宏时）生成的代码，并从旧数据库的代码中获取 Switchboard。我相信该代码是使用 Access 2003 创建的，但它仍然可以完美运行（见下文）每个总机有 8 个按钮的限制，但对于大多数应用程序来说应该足够了。

Option Compare Database

Private Sub Form_Open(Cancel As Integer)
' Minimize the database window and initialize the form.

' Move to the switchboard page that is marked as the default.
Me.Filter = "[ItemNumber] = 0 AND [Argument] = 'Default' "
Me.FilterOn = True

End Sub

Private Sub Form_Current()
' Update the caption and fill in the list of options.

Me.Caption = Nz(Me![ItemText], "")
FillOptions

End Sub

Private Sub FillOptions()
' Fill in the options for this switchboard page.

' The number of buttons on the form.

' Set the focus to the first button on the form,
' and then hide all of the buttons on the form
' but the first.  You can't hide the field with the focus.

    Me("Option" & intOption).Visible = False
    Me("OptionLabel" & intOption).Visible = False

' the first item for this Switchboard Page.

Answer 3

在 Access 365 中，将 Switchboard 宏转换为 VBA 时似乎有两个错误：一个在 On Current 事件过程中，一个在 打开时 事件过程。错误消息仅指向 On Open 过程，而 On Current 事件过程似乎也需要更改。

当前： 这会生成运行时间错误 32538 "TempVars can only store data. They cannot store objects."。将TempVars.Add"CurrentItemNumber"、ItemNumber改为
TempVars.Add"CurrentItemNumber",ItemNumber.Value.

打开时： 这会产生编译错误。将 Call Argument & "()" 的所有实例更改为 Eval (Argument & "()")。虽然不是必需的，但是良好的编码习惯，将所有具有 Argument 的 DoCmd 语句更改为 Argument.Value.

希望对您有所帮助。
