Hi, I am very new to multi threading. my requirment is read the data from DB(universe DB) and create the report and export to excel. there might muliple report created say 10 to 15 reports
Here what i have to do is two threads 1) read the data from DB for reports 2)with each data create excel
And these process should work as background process.
Pls help, any idea to do this is deeply appreciated.

Thanks in Advance.

That doesn't make a whole load of sense: why have two threads doing this? Why not have a thread (from the BackgroundWorker[^] pool) for each report? Then it keeps the related tasks together - each thread reads data, create report, export to excel, end thread.
Otherwise, you have to pass data between the threads, presumably using some form of queue - it's much easier to handle if the thread handles the whole task, particularly as the next stage can't start until the previous one is complete.

@OriginalGriff - Thanks for ur response. Why i thought of 2 thread is, querying the data from DB also time consuming and with generating the report. So while the thread is generating a report(as excel) let the other thread queries the data from DB. Both the thread should be Synchronized. Any other idea is also welcomed.

Why go to that complexity? If you use them as background threads and an operation is slow, then others can "get in" and do something - they won't all lock up waiting for the DB read to finish.
