Using timersHello,
1. Is there any 'optimal' number of timers can be used on one form? 2. Which design will be more efficient: A. using one timer and combine different events using If... Then statements. Because each event requires different time interval change timer intervals for each event will be included in the code or B. For each event use different timer with preset time interval Your thoughts please, Jack What are you trying to do?
Option: One timer with a low interval (1 second maybe) and have the timer event check for how much time has passed and react accordingly. Then your timer event can trigger several events based on passed time. Remember timer events are low priority events with the system and instead of checking for a time being reached you should check for a time being passed... -- Show quoteHide quoteChris Hanscom - Microsoft MVP (VB) Veign's Resource Center http://www.veign.com/vrc_main.asp Veign's Blog http://www.veign.com/blog -- "Jack" <replyTo@newsgroup> wrote in message news:OJ$FmLUKGHA.1676@TK2MSFTNGP09.phx.gbl... > Hello, > 1. > Is there any 'optimal' number of timers can be used on one form? > 2. > Which design will be more efficient: > A. using one timer and combine different events using If...

What I am worrying about is that my form has already 15 timers on it and I am in need to add some more. Not all the timers are active at the same time of course, but one or two. I do not want to have big overhead, or the code became too 'heavy'.

timers are used for: -main timer --> heart of the system -retrieving TAPI callbacks -detecting busy line -scheduler -recording -playing -running script -finding specified window (FindWindow() ) -redirecting voice -buffering -monitoring should I go on?

I have just tried to answer your question. You asked me what I am trying to do and I explained. Each timer has specific task as shown. At most only one or two timers are active at the same time. What I am trying to find is how that timers are weighting on my code? Is there a better approach to reduce number of timers and cumulate more code inside them? It was my original question, btw, Jack Show quoteHide quote "Veign" <NOSPAMinveign@veign.com> wrote in message news:enwL%23ddKGHA.524@TK2MSFTNGP09.phx.gbl... > Good luck.

You really haven't provided enough information on coming up with an alternate solution. By the sound of the complexity of your application I'm not sure you could. What's hard to tell is the why. Like why does running a script require a timer or why does finding a window need a timer. I guess I stand by my original statement that a single timer that monitors all the events is the way to go. Also, its hard to tell if you even need everything on timers. Maybe what you could do is start consolidating timers that perform a common function like; Recording, playback, redirect. See how this works for you and keep moving in the direction of removing timers and not adding new ones... Also, I guess it would be nice to try and understand 'why so many things need times' -- Show quoteHide quoteChris Hanscom - Microsoft MVP (VB) Veign's Resource Center http://www.veign.com/vrc_main.asp Veign's Blog http://www.veign.com/blog -- "Jack" <replyTo@newsgroup> wrote in message news:eDwAHkdKGHA.3144@TK2MSFTNGP11.phx.gbl... > No need to get offended.

with the intervals you expect. Because VB can do one thing at a time, and by the time you expect it to run your function at the interval you set, it will be busy doing the first function. You have to run things in sequence rather than by timer intervals. And don't expect it to run things for you in intervals of 250 or 500, because it would take that long to run your first function. Yes timers do run in the background, but will not function if you have it busy doing something else. Use one timer. Set a long variable to count time, then call functions when the variable reaches time desired. 'Example: Dim T500 As Long, T750 As Long, T1000 As Long, T1250 As Long Private Sub Form_Load() Timer1.Interval = 250 End Sub Private Sub Timer1_Timer() T500 = T500 + 1 If T500 = 2 Then T500 = 0 Call theFunction500 End If T750 = T750 + 1 If T750 = 3 Then T750 = 0 Call theFunction750 End If T1000 = T1000 + 1 If T1000 = 4 Then T1000 = 0 Call theFunction1000 End If End Sub Public Sub theFunction500() MsgBox "500" End Sub Public Sub theFunction750() MsgBox "750" End Sub Public Sub theFunction1000() MsgBox "1000" End Sub Show quoteHide quote "Jack" <replyTo@newsgroup> wrote in message news:eDwAHkdKGHA.3144@TK2MSFTNGP11.phx.gbl... > No need to get offended.
