VSTO Outlook加载项，是否需要从主线程完成UI操作? [英] VSTO Outlook add-in, does UI manipulation need to be done from main thread?

问题描述

我正在维护Outlook的VSTO加载项，它具有处理与服务器同步的BackgroundWorker.我希望工作人员在用户界面中触发用户错误(更改按钮上的图片，在设置窗口中启用消息).

是否需要在初始线程中进行UI操作?

此StackOverflow答案不会，但是解决方案

是的，所有Outlook/Office对象模型访问都必须从主线程完成.参见带有Windows窗体和工作线程的VSTO

I'm maintaining a VSTO add-in for Outlook, and it has a BackgroundWorker that handles syncing with a server. I want the worker to trigger user errors in the UI (changing the picture on a button, enabling a message in a settings window).

Does UI manipulation need to be done from the initial thread?

This StackOverflow answer says not, but a comment on it says so. It's for Excel, but still for a VSTO add-in. I tried and it seems to work from either thread, but there could be a race condition I haven't hit yet.

解决方案

Yes, all Outlook / Office Object Model access must be done from the main thread. See VSTO with Windows Form and Worker Threads
