Check The State Of A Certain Key But Only Inside Timer Event?
Sep 14, 2009I want to check the state of a certain key, but only inside timer event. So my sub will be something like.......
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Need code here along the lines of an old fashioned... 'If Input="Q" then......"
End Sub
I'm not sure how to check for keyboard input except for inside a 'Keydown' event.
Asp.net - Local Static Variables In Timer.Tick Event (Stopping A Timer)
Jul 9, 2009I have a timer on a page in ASP.NET.
After a certain period of time elapses, I want to disable the timer.
I want to put a static variable in the timers tick event that will track how many seconds have elapsed.
My question is, will this work?
If user X and Y are viewing the page will they both have separate local static variables?
What is the best method of shutting down an ASP.NET timer after a certain elapsed time?
Synchronize The Timer Event So That The Timer Executes From The Background Worker Thread?
Apr 23, 2009I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.
My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.
1. How can i close my background worker and at the same time have the timer to be stopped?
2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?
3. Is there a better approach for me to adapt?
Create An Array Of Timer - Raise The Tick Event For A Particular Timer?
Jan 11, 2011I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:
public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20
[Code]...
i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.

View 4 RepliesProgress Bar Directly To A Timer?
May 7, 2009I have been trying to accomplish what i thought was a fairly straightfoward task of tying a progress bar to a timer. I have a simple VB app that rotates between windows for a kiosk-type application. I would like to have a progress bar that counts down until the next window will rotate. So i thought it would be taking the total value of the timer and assigning that as the value of the progress bar, then update the progress bar while the timer is going so it can tick down to the end, then restart

[Timer] Trigger Event Manually - User Must Wait For A Minute Before The Event Is Triggered
Feb 12, 2010Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 60000
Timer1.Enabled = True
[CODE]...
Is it possible to force this event to occur instead of waiting for it?
Make A Timer That Beeps 3-5 Times And Runs A Progress Bar?
Jan 9, 2009I am trying to make a timer that beeps 3-5 times and runs a progress bar. All it has to do is click start (timer set for 2 minutes starts) and as time runs out the progress bar fills. When the time is up 3-5 beeps happen. I am missing the coding for the 3-5 beeps and design parts for it and all coding for that along with code for setting the 2 minute timing. There is no label for telling the time left or to go just a progress bar. Here is my code so far.

VS 2010 Make A Timer, Inside Of A Class?
Dec 3, 2010I am trying to make a timer, inside of a class, tick, by calling it from a backgroundworker. It never ticks (the Tick event is never raised), but the Timer shows as Enabled (with Interval set to 1).
Here is the simplified

If I move the code inside the Thread1_DoWork procedure into the Button1_Click procedure, the code works fine (by bypassing the backgroundworker). But, when it is called inside of the backgroundworker, it doesn't work at all.
Calling .dll Method From Inside A Timer Won't Work(Console Application)?
Nov 26, 2009I have a .dll file (Interop.ACTMULTILib.dll) that I use to connect to a PLC. This .dll contains a sub called ReadDeviceBlock2(byval devicename as string, byval size as integer, byref data as short). When I call this method in my main it works fine, if I call it from another method that was called by main it works as well.However, it doesn't work when I call it from my Timer_Elapsed sub? I guess this has to do something with threads but I can't figure it out.

View 12 RepliesDisplay Total Up Value From Progress Event
Jun 21, 2010I'm trying to display the total extraction progress of a zip file as below. This gives me the total file size of all uncompressed files in the zip:
For Each backup In zip
TotalSize = backup.UncompressedSize + TotalSize
Next
I'm then using this to get the current bytes transfered:
TranferTotal = e.BytesTransferred + TranferTotal
The problem is this value resets after each file is extracted from the zip. I was expecting the above to "tally up" the total so I could use it for the progress bar but it seems to still reset after each item? Also, I'm using a global varible for the transfer total, if there a better method to transfer this information to the StepEntryProgress? The reason I'm doing this is because the DotNetZip Library does not support multiple extraction in this way, so I need to tally up in this way.
Code:
Imports Ionic.Zip
Imports System.Threading
Imports System.ComponentModel
Public Class Form1
Dim TotalSize = 0
