If you browse the Virtual Center CD and go to the folder vpx and expand the VPX.cab file you will find the SQL scripts that install the SQL jobs. It's three files:
job_schedule1_mssql.sql.v3v4.t
job_schedule2_mssql.sql.v3v4.t
job_schedule3_mssql.sql.v3v4.t
Open them in a text editor and you will see the actual SQL script and that each job contain two steps.
I'll take schedule1 as example. You will find job name and description:
@job_name = N'Past Day stats rollup',
@description = N'This job is to roll up 5 min stats and should run every 30 mins',
Further below you see the two job steps and their actual SQL commands (two different stored procedures):
@step_name = N'Past day stats rollup',
@command = N'EXECUTE stats_rollup1_proc',
and
@step_name = N'Delete past day rolled up records',
@command = N'exec purge_stat1_proc',
Since SQL 2005 Express Edition do not have an SQL Agent to schedule jobs you could mimic the the Virtual Center SQL jobs by scheduling those stored procedures in OS scheduled task or using some other form of scheduler.
