查看各数据库的连接数：

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

查看总连接数

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
    

连接的更多信息（账号等）, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)，注意，需要sysadmin权限。

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

show total Connections

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
    

If you need more detail, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)

TGitCache任务管理器中杀掉后依然会重新启动。这个进程的功能是实时扫描纳入SVN版本控制的文件夹，如有修改，显示不同的图标以示修改。但是这会占用内存、IO等资源

1.关闭方法：Explorer右键菜单→TortoiseGIt→Settings→Icon Overlays→Status cache，将这一项设成None。

2.刷新图标状态
使用“Explorer右键菜单→TortoiseGIt→Check for modifications”显示差异

Have you ever needed to view your chat messages while reading an article within WeChat or playing a Mini Game? It’s a hassle to back out of your article mid-stream in order to check your messages.

Floating Window was initially introduced in 2017 as a way for you to save your place and minimize an article while checking other parts of WeChat like chats. We’ve now greatly expanded Floating Window so that you can “float” up to 10 different windows. Windows can be articles, document previews, or nearly any other type of content. When viewing a music or audio Mini Program, you’ll also be able to see what’s playing via our new music display in Floating Window. Floating Window makes multi-tasking within WeChat a breeze.

When viewing an article, document preview, or other content, simply swipe right and hold to minimize the article to your Floating Window.
