Question

我有一个应用程序，我第一次使用功能区。我可以填充自己的控件，并回调子程序没问题。我现在处于开发阶段，我希望隐藏/动态显示一些组以提供更好的用户体验。

我可以通过更改CallbackGetVisible中的visible属性来隐藏/显示工作簿加载期间的组，但是当我更改值并在应用程序运行时调用RefreshRibbon时，它会在Rib.Invalidate处中断。测试显示Rib（IRibbonUI）对象（Rib）设置为空。有没有办法让对象保持活跃状态，或者还有其他我缺少的东西？

代码

Option Private Module
Option Explicit
Const errModule As String = "modRibbon"

'Module Variables
Dim Rib As IRibbonUI
Public MyTag As String

Sub CallbackGetVisible(control As IRibbonControl, ByRef visible)

    visible = True

End Sub

Sub RefreshRibbon()

    Debug.Print "RefreshRibbon"
    If Rib Is Nothing Then
        MsgBox "Error, Save/Restart your workbook"
    Else
        Rib.Invalidate
    End If
End Sub

'==================================================================================================================================================================
'Called On Load From XML
'==================================================================================================================================================================
Sub onLoad(ByVal ribbon As IRibbonUI)
On Error GoTo err_Handle
Const strError As String = "Error - Please Contact " & gblDeveloper & " Quoting 'OnLoad'"

    Set Rib = ribbon
    Rib.ActivateTab ("MyCustomTab")
    GoTo Cleanup

'Set Any Objects to Nothing, Exits Sub
Cleanup:
    Set Rib = Nothing
    Exit Sub
'Throw Error
err_Handle:
    errMsg strError & Chr(10) & Err.Description & Chr(10) & errModule
    Resume Cleanup
End Sub

修改

我认为Rib.Invalidate会导致CallbackGetVisible运行，因此会相应地设置Group的visible属性。但是当功能区为Nothing时，Invalidate将不会运行。

Answer 1

您将@设置为子Rib的{{1}}部分中的Nothing。

删除该行，只要保存Cleanup:变量的代码模块打开，就可以使用onLoad对象。

动态控制VBA功能区
