SystemTimer - SetTimer fails

[jkcool]

Hi All,

I have a VB code in which System Timer (see below ) is used.

Declare Function SetTimer Lib "user32" (ByVal hWnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerProc As Long) As Long


The program scans a table for a specific interval and once scan is complete. It sets the timer using SetTimer function. and after the specified seconds , it triggers the event again.

The code works fine , but some times the timer is being set correctly , but after the specific time period the event is not getting triggered.

And it looks like application hangs.

Is there any known problem with the system timer ? If so , what's the alternative way ..

Thanks in advance in

JK
