best way to ...

[JABOSL]

I would like to know the best way to have a program start working on startup and keep looping until someone clicks file exit. It needs to go as fast as possible.

I've used a loop like:

dim continue as boolean = true
do while continue

I sprinkle application.doevents inside the loop so the program remains responsive and the file/exit button sets continue to false.

But, I've heard folks say that's bad. One recommended a timer. I can see a timer starting a 5 minute process ever 15 minutes or something like that but I can't see it helping me. I have what I hope will be a second or less process and as soon as it's done the process needs to be done again. Over and over until eternity.

Is there a more appropriate way of doing it in .net than the do while continue method?

What are you trying to do in your process perhaps there is a beter way of doing it.

In this program I have to "watch" a database table for new records being added. When a record is added I take part of the data and create a soap message which is sent to another company. The other company sends a reply back and the reply is added to the record in the database table and then a new record is created in another table also containing part of the received reply.

I really can't change the process much. My boss, colleagues and I all had a part in deciding on the process. These folks aren't dumb. They have good reasons for their choices. I just have to get it coded and want to know how to best loop. I frequently have to write looping programs that run on dedicated pcs or servers sitting in a computer room doing what they do hopefully w/o a hitch for weeks, months, years, ok they probably never make it a year before someone reboots one but you get the idea.

Thanks

Actually, the timer idea is not bad. If you are sure that the process takes less than a second, you could have a timer fire once per second to check the database, etc. Basically, just take the code inside your loop and put in the timer's Tick event handler.

I would suggest threading then. Run the code you have to process in a seperate thread so the main thread stays responsive.
