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.

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?
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.

in Timer.Tick
I used raiseEvent myevnt. I also raised the event from a button click. This event is handled in a windows form where the control is used, My problem is event is firing when the button is clicked but not firing from the timer.tick. Is there any problem from Timer.Tick.
Changing Visibility Of Picturebox With Timer Tick?
Jun 10, 2012I have a timer that on tick checks to see the value of a an element in an array using a counter on another form as well. The picture boxes are initially set to false for visible and they should become true when the timer ticks and the element is equal to 1. I know that the pictureboxes have a valid picture in them because if I initialize them as TRUE first, it shows up properly. I also know that I am entering the IF statement because I can put a simple MsgBox with any string in the IF statement and it will display when the requirements are set. But yet the pictureboxes still do not change.

Create A Timer That Will Activate A Tick Event?
Jul 11, 2011I am attempting to create a timer that will activate a tick event every 1 second until stopped by an "If" statement. The tick event should then drive a clock measuring time in units of hours, minutes and seconds. The if statements handle the time readout, timer stop and activate another form after a set number of hours have elapsed. I have tried several different methods and while my application is running, it does not add increments to the integers representing the time units, refresh the displayed time units, or perform any of the timer related functions. I assume the cause is that I just don't know as much as I think I do (which isn't much)
Here is the applicable code:
Imports Microsoft.VisualBasic.ApplicationServices
Imports System.IO
Public Class SessionManager

Interface And Graphics :: Delay In Timer Tick?
Dec 2, 2008I am running an application to control at 1, 10 and 100 Hz to compare their response for a control systems class. I have a timer that reads data from hardware, a timer that updates the screen and does the control, and a timer that writes data to a file. I've been having problems with the speed of the write timer, so I created a buffer.It takes 0 ms to load the buffer, and the buffer is written to file using a synchronized streamwriter and a thread every 100 iterations. It also flips back and forth between two buffers so there are no read/write conflicts.If I try to run at 10 Hz, the timer executes on average every 109 ms. If I try to run at 100 Hz, the timer executes on average ever 15-16 ms.

Timer.Tick - Remove A Control & A Hint?
Feb 3, 20111.) I would like to cause a Timer.Tick event in code. I know you can use PerformClick to cause a Click event. Is there a way to do the same with a timer?
2.) I have several "TextBoxes" listed as being on a "Form" but they cannot be seen. I have copied and pasted these during the design phase but have renamed the copies since. Is there a way to purge the unseen TextBoxes?
Hint: If you have "Windows 7", at the desktop, press <CTRL><SHIFT> and Rotate the Wheel on the Mouse. This will re-size the Icons on the desktop. "THIS ALSO WORKS IN THE VB2010 IDE" and allows you to Zoom the code window.
VS 2008 Timer Tick-event Never Occures?
Oct 21, 2009I'm trying to make my application react the way I want if the internet connection goes down, because the application need a permanent internet connection to work properly. This also includes if the server my program is trying to connect to goes down/stops or something.
What I want is that if a exception occures when trying to connect to the server, i calls a sub wich stops all timers, disables some buttons and comboboxes. At the same time it starts a new timer named "retrytimer". The retrytimer checks every fifth second if the connection is re-established. If it is, it activates all the controls and disables itself.
For some reason, the retrytimer tick-event never occures. I've tried inserted a breakpoint on the first line of the event-sub, but it never hits. If I check the enabled-property of the timer, it is set to "true". Why does this happen?The timer is made in the design window, and it's default enabled-property is set to false.Here is my sub wich deactivates some controls and starts the timer:
vb.net
Private Sub connectionLost(ByRef errnr As Integer) connected = False If starttimer.Enabled Then starttimer.Enabled = False If resulttimer.Enabled Then resulttimer.Enabled = False If radioposttimer.Enabled Then radioposttimer.Enabled = False If runningtimer.Enabled Then runningtimer.Enabled = False
[Code]...
But here is the funny part! If I start the application without a internet connection, everything works the way I want. But if I disable the internet connection in the middle of my program, it acts as described. The lasts messagebox in my connectionLost-sub are shown, and the timer is set to enabled = true.
Does anyone have a clue? EDIT: I think I've narrowed down the problem quite a bit.It seems like the timer won't work correctly if the connectionLost-sub is called from within a BackgroundWorker. If it is called from something else than inside a BackgroundWorker, it seems to work the way I want.

Timer Tick Not Happening On Form / When Told To Show By Delegate
Dec 6, 2010I have an app that basically monitors states, then when a state has changed, a notify form is triggered to show for the user.Timers are used on the form to showing a fading in/out of the form (somewhat like MS Outlook new email notification windows).I'm using a delegate from the main form to show the form, but when the first timer in the form is set to start, the timer's tick event is never ran. Everything up to that point in code works perfectly though.Is there something I need to do in order for the tick event to fire, like it would without the use of a delegate to show the form?[code]

Me.Height = Me.Height + 1
End If
If Me.Height = "500" Then
Me.Height = Me.Height - 1

Now i want it to stop when it hits 500, and then scroll back...
Ive also tried this...it stop at 500, but doesnt scroll back:

End If
If Me.Height = "500" Then

C# - Button Click In Repeater In Updatepanel Not Triggered Until AsyncPostBackTrigger Timer Tick?
Dec 16, 2010I have an update panel that has a timer set as the AsyncPostBackTrigger.In this Update Panel I have a repeater and in the repeater I have a few buttons which have on click events.
The on click of these buttons does not appear to fire until the timer has ticked.I have tried debugging and this is what seems to be happening, either way it takes ages for the button click to actually fire.
Does anyone know why this would be and what I can do about it?

Set My Timer Interval To 1000 And Enabled It?
Feb 12, 2011I am trying to write a simple code that will essentially change the background oclor of a form from say red to green, like every five seconds.(Actually, it will be green 4 and red 6 seconds). I set my timer interval to 1000 and enabled it. So when I write my if/then statements in the timer area, would I be using timer.interval <=4, or timer.interval <=4000 to count off four seconds?
View 1 RepliesTimer Tick Event And Serial Port / Read And Display Live Data?
Jun 21, 2009[code]...
I have a quick question regarding the serial port and timer tick event. Basically i have a micro processor connected to the PC via the serial port. With a baurd rate of 38400 set.When the PC sends the micro ":K + VBCRLF" the micro response with a string of information (ASCII encoded) and delimited with a "," and at the end of the transmission a cartridge return line feed is added.Example of sent string:
"12,1134,123,545,76,6868,34,232,1,2,3,6,7,8" These numbers are then split using the VB mystring.split(",") function into an array of strings, then the numbers are converted using ctype. After which my UI is then updated.I have Witten the code in a tick timer event using a timer count of 300ms. Although the program runs and the UI is updated i end it with lots of exception errors. I think allot of this is down to the serial port either timing out or not reading complete string.Or possibly the timer has not executed all the code before another tick event happens Even after adding a few try catch statements i am still having problems. Can anybody suggest a better way of doing it?I was thinking of using a do while loop and at the end a sleep function instead of the timer tick event.I need the speed as i am trying to read and display live data.

Time Program Tick Method - Where To Place It
Feb 12, 2011I'm trying to complete a time program for a class that I am currently taking in which it's supposed to utilize a Tick Method. Essentially, the Tick should be incrementing the time by one second. The problem is that I don't know where to place it. The book I have doesn't go much into this, just the code. I have also placed the timer in the Designer, set enable to True and set the interval to 1000 milliseconds. This is the code I found for the Tick Method
