2 thread run simantaneously

[Arjun_Sarankulu]

I have the application In which i am ruuning the procedure which runs the Sql Job
and at the other end i need to show the job history in grid whose query is select job_id, step_id, step_name, message, run_date from sysjobhistory
where run_date = replace(convert(varchar(10), getdate(), 121),'-','')
the job which i am running internally runs many job
I want to show job status one by one in grid not after the procedure fully executed
Till now i have not done Thread Programming
Search a lot but didnt got the same

Very rarely will you find a solution to your exact problem. Since you haven't done any threaded development thus far, I'd recommend a general threading tutorial first, then something specific to your current problem of updating the UI with progressive results from a long running background thread.
