当多个用户登录Windows时，如何获取活动用户？ [英] How to get the active user when multiple users are logged on in Windows?

问题描述

假设目前有多个用户在Windows上登录。说， user1 登录，然后切换用户和 user2 登录，（不使 user1 注销）。假设有一个应用程序在用户登录时运行。有两个用户 user1 和 user2 登录， user2 作为活动用户，并且有两个应用程序。

我的问题是：应用程序如何知道其相应的用户是否活动？即， user2 域中的应用程序确定其用户处于活动状态，而 user1 域中的应用程序确定其用户当前处于非活动状态。感谢！

解决方案

您可以致电 WTSGetActiveConsoleSessionId 获取终端服务（又名快速用户切换 远程桌面）当前在物理控制台上处于活动状态的会话ID。

您可以调用 WTSQuerySessionInformation ， WTS_CURRENT_SESSION 为会话标识符和 WTSSessionId 为 WTSInfoClass 获取当前的终端服务会话ID

如果活动会话ID和当前进程会话ID相同，则当前进程对应的用户在物理控制台上具有活动会话。 p>

如果你想知道的是当前进程运行的会话是否是活动的（但不一定在物理控制台上），你可以改用 WTSConnectState 选项 WTSQuerySessionInformation 。

Suppose there are multiples users currently logged on on Windows. Say, user1 logs on, then switch user and user2 logs on, (without making user1 log off). Suppose there is an app which runs when user logs on. There are two users user1 and user2 logged on, with user2 as the active user, and there are two apps.

My question is: How does the app know whether its corresponding user is active or not? I.e., app in user2 domain determines that its user is active, while app in user1 domain determines its user is currently inactive. Thanks!

解决方案

You can call WTSGetActiveConsoleSessionId to get the terminal services (aka "fast user switching" aka "remote desktop") session ID that is currently active on the physical console.

You can call WTSQuerySessionInformation with WTS_CURRENT_SESSION for the session identifier and WTSSessionId for WTSInfoClass to get the terminal services session ID for the current process.

If the active session ID and the current process session ID are the same, the user corresponding to the current process has the active session on the physical console.

If what you want to know is whether the session that the current process is running in is active (but not necessarily on the physical console) you can instead use the WTSConnectState option to WTSQuerySessionInformation.
