Use a separate thread for it. On top of each thread catch all exceptions and notify main UI thread on every exception using Control.Invoke.

can u give me a tutorial link on doing that?

Simon Bang Terkildsen 26-Sep-11 2:43am

I simple tutorial is not enough, if you want to do multithreaded programming you have to dedicate a good amount of time and probably some money for a good book. Multithreaded programming is not a simple task, even though SA makes it sound like it.

hey simon, so can i find another solution without using multithreading?

Sergey Alexandrovich Kryukov 26-Sep-11 2:54am

Forget about it; don't invite troubles. Use multithreading.

Like SA says this requires multithreading. All I'm saying is that I do not find it wise to use multithreading if you don't know a good deal about it.
I myself have learn through trail and error, it's only the past few years I've realized the value of books. I took me atleast 4 years of trail and error and debugging multithreaded issues before I had a good understanding of multithreading, even today I do not take multithreaded programming litely and any developer (even very seasoned developers) who does will be in for a world of trouble sooner or later, this is my belief not a fact. though I feel so strongly about it that I often state it as a fact.

Thank you, Simon.
"Even SA" sounds flattering. :-)
Multithreading needs more of understanding, less of "training". Not using threads leads to much more tricky situations then using them, in cases where threads are appropriate.

Yousif, don't fool yourself. You do need a thread, that's it.

I don't completely agree with you, if you do not know what you're doing sooner or later you will run into a problem where you just will have to give up or finally learn about multithreading and realize you've made alot of mistakes (start rewriting).
Multithreading is the one aspect of programming that I do not believe you can learn by doing, I believe you need to know exactly what is going on even when using the TPL you should know what is going on at the OS and hardware level.

Ok thanks alot but how am going to use this thread? the thread is going to read from the database or what is the job of this thread will be?
