Word加载项工具栏问题
我正在构建一个 word2k3 插件，并且正在创建一个包含相关按钮的新工具栏。一切似乎都工作正常，除了根据谁正在查看活动文档，必须启用/禁用某些按钮。这不是问题，因为我只需将 button.enabled 设置为 true/false 就可以了。
我的问题是，在启用/禁用这些按钮几次后，我突然收到 Hresult 错误。我尝试用谷歌搜索该错误，它显示了有关按钮不存在或其他内容的信息。 确切的异常如下： {"Exception from HRESULT: 0x800A01A8"} System.SystemException {System.Runtime.InteropServices.COMException}
我对这个问题感到非常困惑，因为它是随机发生的，我只是不知道会发生什么造成它。
ps：我的菜单栏上也有按钮，但这个问题从来没有出现过，只出现在工具栏上。
干杯
I am building a word2k3 add-in and i'm creating a new toolbar containing the relevant buttons. All seems to work fine except, depending on who is viewing the active document, certain buttons must be enabled/disabled. This is not a problem as I simply set the button.enabled to true/false and it does the trick.
My problem is that after enabling/disabling these buttons a couple of times, I suddenly get an Hresult error. I tried googling the error and it says something about the button not being there or something.
The exact exception is the following: {"Exception from HRESULT: 0x800A01A8"} System.SystemException {System.Runtime.InteropServices.COMException}
I'm utterly confused about this issue since it occurs at random times and I just cant figure out what might cause it.
p.s.: I also have buttons on the menu bar and this problem never occurs there, only on the toolbar.
cheers

听起来不知何故你失去了对按钮的引用。它们在全局变量中吗？这些变量是否会被清除（也许是通过您忘记的事件代码）？
It sounds like somehow you're loosing the reference to the buttons. Are they in global vars? Could those vars be being cleared (maybe by event code you've forgotten about)?
