I am using timer control in a form, i call this control from a vb class file which internally called by vb module.
Timer is working until i exit from vb class file. When i check the value of timer.enabled in vb module (after existing from vb class) it is false.

Can anyone help me why the timer stops when it exits class file?

Thanks.

This is a kind of very usual problems you face with timers, which just needs more accurate programming. Without seeing your code, it's hard to say anything certain (isn't it obvious?). Please see: SSCCE on how to do it.

Besides, you need to explain why would you needed to use a timer in first place, not anything else. In most cases, using timers is not the best option.

It's a migrated code from vb 6 to VS 2008. The code was working in vb 6. After migration, i checked the timer is working but it stops when i exit vb class file.

First of all, rethink using timer. VB6 was never an adequate development tool. For example, it lacks threading; and chances are, you would need it, not timers.

Is it possible to share some example program which suits this scenario?

This is no good in first place. It's bad to use timers, and bad to use DoEvents. You need to explain your ultimate goals, before moving any further.

Ok. My requirement is to scan a directory in few seconds to see is there any file waiting to be processed. The form and class are common files for many applications. Timer logic and scan should happen in these files only. Can you guide me in this?

Late to the party but throw all of this away and look up the .NET FileSystemWatcher class.
