How to clear all database connection using SQLDMO?

Hello guys! I'm using SQLDMO to restore a database backup. The problem is, the program cannot restore the backup if there are active connections using the database. Is there are way to clear all database connections using SQLDMO (or other libraries)? Thanks in advance

You could create a storedproc in master that kills any existing spids per db, then run that proc from DMO as part of the restore job.. something like this

CREATE procedure sp_KillOldspids

@.dbName varchar (30) = NULL
AS

set nocount on

declare @.currentspid int,@.cmdstring varchar(30)

dECLARE OPENSPIDS CURSOR FOR SELECT [SPID] from [MASTER].[DBO].[SYSPROCESSES] WHERE DBID = db_id (@.dbName)
OPEN OPENSPIDS

FETCH NEXT FROM OPENSPIDS INTO @.CURRENTSPID

WHILE @.@.FETCH_STATUS = 0
BEGIN

SELECT @.cmdString = 'kill ' + convert(varchar(10), @.CURRENTspid)
IF @.@.SPID <> @.CURRENTSPID
BEGIN
EXEC (@.cmdString)
END
FETCH NEXT FROM OPENSPIDS INTO @.CURRENTSPID

END

CLOSE CURRENTSPIDS
DEALLOCATE CURRENTSPIDS

hopes this helps.
