Take a database offline when it has open connections

I want to take a database offline to do some testing. When I select the database > right click > Select All Tasks > Take Offline I get the error:

[Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 5070: [Microsoft][ODBC SQL Server Driver][SQL Server]Database state cannot be changed while other users are using the database 'myDB'

Two questions:
1) How do you determine who or what is connected to the database?
2) How do you kill those connections?

Thanks

Hi TAMUQITS,

You can use sp_who to see who's connected:
EXECUTE sp_who

You can then identify from those results who is connected and then kill those processes using the KILL statement with the associated spid:
KILL <spid>

I have 104 connections. Is there a simple way to kill them all at once?
