以编程方式启用/禁用Outlook外接程序 [英] Enable/Disable Outlook Addin Programmatically

问题描述

我为Outlook 2013创建了外接程序.

I have created Add-in for outlook 2013.

我想打开/关闭其他插件.所以我用下面的代码来做到这一点.

I wanted to on / off other addin. So I have used below code to do that.

Outlook.Application OutLook = new Outlook.Application();

if (OutLook.Application.COMAddIns.Item("OutlookAddIn").Connect)
{
 OutLook.Application.COMAddIns.Item("OutlookAddIn").Connect = false;
}
else
{
OutLook.Application.COMAddIns.Item("OutlookAddIn").Connect = true;
}

但是，只有当我以管理员身份打开Outlook时，它才能正常工作.对于普通用户，它不能正常工作.

But it is working fine, only if I open outlook as administrator. For normal user, it is not working fine.

那么我还有其他方法可以实现这一目标吗?或者我只能以管理员身份运行此代码?

So is there any other way I can achieve this? or I can run only this code as admin?

推荐答案

您必须是本地管理员或超级用户才能修改HKLM.普通用户没有足够的特权来修改 Windows注册表项用于加载项.很有可能该加载项已在HKLM配置单元中注册，对吗?

You need to be a local admin or a power user to be able to modify HKLM. A normal user doesn't have sufficient privileges for modifying the windows registry keys for the add-in. Most probably the add-in was registeredin the HKLM hive, am I right?

当然，对于每台计算机外接程序，如果您的应用程序是在具有管理权限的情况下运行的，则可以设置Connect属性.但是，在启用了UAC的系统上，除了具有管理权限之外，还必须提高应用程序的流程.

Of course, for a per-machine add-in, you can set the Connect property if your application is run with administrative permissions. But on a system with UAC enabled, in addition to having administrative permissions, the application process must be elevated.

您可以在Outlook中手动禁用加载项，甚至是每台计算机的加载项.这意味着您可以添加HKCU条目来完成它.如果我查看注册表，则HKEY_CURRENT_USER下Addin的'LoadBehavior'值已更改.但是HKEY_LOCAL_MACHINE下的'LoadBehavior'的值未更改.这是预期的行为-普通用户不能为所有用户禁用该插件.

You can disable the add-in manually in Outlook, even a per-machine add-in. It means that you can add a HKCU entry to get it done. If I look at the registry, the value of 'LoadBehavior' of the Addin under HKEY_CURRENT_USER has changed. But the value of 'LoadBehavior' under HKEY_LOCAL_MACHINE has not changed. This is expected behavior - normal user can't disable the Addin for all users.

请注意，在这种情况下，该加载项将仅对当前用户禁用.

Be aware, in that case the add-in will be disabled for the current user only.

这就是为什么我建议在运行时禁用外接程序的所有功能，而不是尝试将其关闭.在运行时，您可以检查用户是否被授权加载加载项，根据身份验证结果，您可以决定是否加载加载项的UI和其他业务逻辑(订阅Outlook事件等). . IE.该加载项将被启用，但最终用户不会注意到这一点.

That is why I'd suggest disabling all features of your add-in at runtime instead of trying to turn it off. At runtime you can check whether a user is authorized to load your add-in or not, based on the authentication results you can decide whether to load the add-in's UI and other business logic (subscribe to Outlook events and etc.) or not. I.e. the add-in will be enabled, but the end user will not notice that.

即使将LoadBehavior键添加到相应的HKCU配置单元中，该加载项也将在下次启动Outlook时加载.

Even if you add the LoadBehavior key to the corresponding HKCU hive, the add-in will be loaded next time Outlook is started.
