正如你可以看到我有一对夫妇的要求无效，使行动，切换..我的按钮。我的加载项启动正常，但有时会崩溃。下面是一些例子在其上加载几乎总是崩溃：
- 打开一个新的Inspector窗口邮件项目，然后再将它关闭
- 多个窗口打开，上下文菜单的自定义按钮，在打开
它发生的场合让我非常肯定它与创建新的上下文菜单或功能区时的自动失效有关，而不是当我自己调用它时。当我删除getEnabled，getPressed ...属性时，该错误不会持续。我无法想出一个办法来压制错误，而不是崩溃或如何解决它。所以，如果任何人都可以帮助，或者可以给我更多的信息，这将是非常感激。如果你需要更多的代码（比如getEnabled，getPressed ...方法），请告诉我。
我的无效方法。请注意，大多数只是返回一个布尔值。这些布尔值保持为ribbon.cs类
public bool getEnabledToggleHistory(IRibbonControl control)
{
return toggleHistoryPanelState;
}
public bool getMailSelected(IRibbonControl control)
{
try
{
MailItem mailItem = getMail();
if (mailItem != null)
{
return true;
}
else
{
return false;
}
}
catch (System.Exception ex)
{
return false;
}
}
public bool getMailAndIDSelected(IRibbonControl control)
{
return mailAndIDSelected;
}
public bool getMailAndIDSelectedAndAttach(IRibbonControl control)
{
if (hasAttachments && mailAndIDSelected)
{
return true;
}
return false;
}
如果我在一个新的Visual Studio实例调试，我得到以下内部私有变量：
Unhandled exception at 0x70B5B2A7 (MSO.DLL) in OUTLOOK.EXE: 0xC0000005: Access violation reading location 0x00000000.
如果我从调试的代码我的解决方案，我永远不会发现错误，也没有说它有一个未处理的错误。它只是崩溃。

我的方法需要无效非常简单，最有可能不是问题。不过，我会张贴一些，如果你想 – 2013-03-25 12:43:06
