Multiple Timers, Events Queue, DoEvents Don't Work

Author	Message
Scott Presto #1 / 4	Multiple Timers, Events Queue, DoEvents Don't Work HI, I have multiple timers. I am using the System.Timers.Timer class. In one of the timer events I have to call a method on another class that requires some intinsive processing. That timer has an interval of about 333ms, taking about 250ms to complete. On the other timer I am performing a some simple calculation. This timer has an interval of 50ms. Even with Application.DoEvents inside a loop of the intinsive processing function called from timer1. The events queue up in timer2 and i get about 5-6 events that happen at the same time. Please help! Thanks!

Steve C. Orr, MCS #2 / 4	Multiple Timers, Events Queue, DoEvents Don't Work It sounds like you need to run these processes on different threads. This way they can all run independently and won't queue up and block eachother like you are experiencing. Using threads, you will also be able to set the priority of different threads so that some get more processor time than others. Here's more info: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcn... vaconThreadingInVisualBasic.asp -- I hope this helps, Steve C.

Scott Presto #3 / 4	Multiple Timers, Events Queue, DoEvents Don't Work i was able to repeat the problem using the threading.timer with the same results. and by creating the system.timer on two seperate threads. it seems the events are the ones sharing the threads not neccisarily the timers.

Scott Presto #4 / 4	Multiple Timers, Events Queue, DoEvents Don't Work unable to get these to move two two seperate threads. the only way that I can do it is to declare a method with no parameters or return values via new ThreadStart (AddressOf obj.MethodFoo) although I tried creating a timer and placing the start() method in there it does not seem to work.
