Hi All..

I really hope someone can shed some light on this.

I have a VB6 application with alot of timer control functions, interfacing with barcode scanners printers and card readers.

It was running perfectly fine, until recently when I upgraded my OS from Win 98SE to Win 2000. Somehow, the application went abit berzerk. It could still run, read/write data, access database etc, but it somehow ignores all the timing controls, and goes by very very fast.

So far I have not changed anything to my code yet, cos I figured, something must be missing from the Win2000 system files. or some of the OCX files may be corrupted or sthg.

I hope someone can give me some suggestions on how to solve this problem. Thanks in advance.

cheers

what do you mean with "timing controls"?

I suspect that your “timing controls” rely on Loops with a certain number of iterations, whose duration was discovered through trial and error.

This was done a lot when computers were just becoming available, back in the late 1980s and the early 1990s, but it is a really fragile undertaking (as you have discovered).

You should switch to using code that relies explicitly on elapsed time periods, rather than on iterative loops.

Look into the Timer statement, and using StopWatch ActiveX controls.

There are also some API functions that allow you to obtain better resolution than Timer does.

If I have misunderstood what you are working with, please forgive me, and just ignore this post.
