通过 vba 访问更改导航窗格组

技术标签:
【中文标题】通过 vba 访问更改导航窗格组【英文标题】：Change Navigation pane group in access through vba 【发布时间】：2014-12-08 20:10:36 【问题描述】：我有一个 VBA 代码模块在访问中创建 4 个新表并将它们添加到数据库中。我想在最后添加一个部分，通过自定义组在导航窗格中组织它们，以便它们都被组织起来。这可以通过 vba 实现吗？
编辑：
我不希望这些表位于未分配对象组中。我想通过 VBA 更改该组的名称。
【问题讨论】：
“在导航窗格中组织”？你要什么？ 所以我有 4 个从宏创建的表，我希望将它们放在导航窗格中的新自定义组中。查看编辑。 我仍在寻找 VBA 解决方案，但根据我的阅读，您无法重命名“未分配”组 - 您所能做的就是隐藏它。您想要的是移动项目（通过 VBA），但我所看到的只是如何手动执行此操作。我会继续寻找...... 好的，谢谢。我找到了这个：social.msdn.microsoft.com/Forums/en-US/…，但我不确定它的含义或如何使用它。 我想我已经找到了解决方案，很快就会发布。您是否已经定义了组？ 【参考方案1】：编辑：添加了更多代码以将其他对象类型添加到自定义导航组。
以下代码会将表格分配给您的自定义导航组。
警告！！我仍在尝试解决表“MSysNavPaneObjectIDs”的“刷新”问题。如果您创建一个新表，然后尝试添加到您的组 - 有时它在第一次尝试时可以工作，有时它会失败但会在延迟后工作（有时长达五或十分钟！）
此时，我通过读取表“MSysObjects”中的信息，然后将新记录添加到“MSysNavPaneObjectIDs”中解决了这个问题（当它失败时）。
下面的代码只是创建了五个小表并添加到 Nav Group 'Clients'
修改代码以使用您的组名/表名。

【讨论】：
这很完美！但是我该如何修改它以包含查询呢？ 我更新了答案以支持其他对象类型。查看修改后的代码。【参考方案2】：非常感谢您的代码， 由于刷新表格的问题，我不得不根据我的具体情况对其进行一些修改。 事实上，我正在重新创建一个表（之前删除旧表）。由于 MSysNavPaneObjectIDs 不刷新，旧 ID 保留在里面。
例如让我们使用我想放入组 TEMP 的表 tmpFoo。
tmpFoo 已经在组 TEMP 中。 TEMP 的 ID 为 1，tmpFoo 的 ID 为 1000 然后我删除 tmpFoo，并立即重新创建 tmpFoo。 tmpFoo 现在位于“未分配对象”中。
在 MSysObjects 中，tmpFoo 的 ID 现在是 1100，但是在 MSysNavPaneObjectIDs 中表格没有刷新，这里的 tmpFoo 的 ID 仍然是 1000。
在这种情况下，在表 MSysNavPaneGroupToObjects 中创建了 TEMP(1) 和 tmpFoo(1000) 之间的链接 => 由于 ID 1000 不再存在于 MSysObjects 中，因此没有任何反应。
所以，下面的修改代码在所有情况下都从 MSysObjects 获取 ID，然后检查该 ID 是否存在于 MSysNavPaneObjectIDs 中。
如果没有，添加该行，然后使用相同的 ID 将其添加到 MSysNavPaneGroupToObjects。
这样看来我没有任何刷新问题（在上层函数中添加Application.RefreshDatabaseWindow）。 再次感谢韦恩，

谢谢，dbs.Execute "INSERT INTO MSysNavPaneObjectIDs ( Id, Name, Type ) SELECT MSysObjects.Id, MSysObjects.Name, MSysObjects.Type FROM (MSysNavPaneGroupToObjects INNER JOIN MSysObjects ON MSysNavPaneGroupToObjects.ObjectID = MSysObjects.Id) LEFT JOIN MSysNavPaneObjectIDs ON MSysObjects.Id = MSysNavPaneObjectIDs.Id WHERE MSysNavPaneObjectIDs.Id Is Null;"
哎呀，让SELECT DISTINCT【参考方案3】：
这是我的代码，它不像主代码那样对用户错误友好，但进行大规模移动应该更快一些。
