VS 2008 Timers And Forms
Mar 18, 2011
I have a background application with a couple of System.Timers.Timer running in it. I also have a NotifyIcon that when double clicked brings up a windows form.
My problem is that sometimes my form gets displayed but then for whatever reason it seems like it's losing focus and becomes un-usable (it just sits there in the background).
So here comes the question now... Can the freeze be caused by the form loading (i.e. me double clicking my NotifyIcon) and the timer tick happening the same time?

I have a form that holds min two timers, One is a 72 hour timer and one is a 12 hour timer.
What I am trying to do is have both run at the same time, when the 12 hour timer expires it'll bring up a form informing the user that in 60 hours the machine will reboot (or they can just hit reboot). When the 72 hour timer expires it reboots the machine.
BUT I know my managment is going to want to be flexable. e.g instead of 72 hours make is 54, and instead of 12 make it 6.
I wish to avoid using global variables
This is the code for the 12 hour one, How do I call it and set i12sec and i12min?
************************************************
Private Sub t12hTimer_Tick(sender As System.Object, e As System.EventArgs, i12sec As Integer, i12min As Integer) Handles t12hTimer.Tick
t12hTimer.Interval = 1000 '1000 Miliseconds = 1 second

Do timers not work in services? I have a service that is running fine, has been for a while. I'm trying to add some work that needs to kick off regularly, so I create a timer that fires every 5-seconds and kick it off when needed. The Tick event never fires. Never, not once. I'm not sure why it doesn't work. Here's the relevant code I'm using. I have 4 backgroundworker threads named, simply enough, bgw1 - bgw4. I wil show you the code for one of the threads so you can see what I'm doing.

I am working with a simple game idea. I wanted to have two players running around shooting each other (very low graphics, like circles and squares). I've got this far; I have the ability to move around both characters, and change directions etc. ive also been able to set up my shooting. Only problem I run into is getting the bullet to move! I cant use a preset timer, because if I used that, I could only shoot one bullet at a time, so I would need to create new ones dynamically.
So my question is; how does one add dynamic timers to a form on runtime, and alter the tick sub so that it moves the picturebox (bullet) and once it can be moved, (I was thinking about using player locations in relation to the bullet, and if they were equal than the health would go down or whatever, but unfortunately, this means it would have to be directly in the middle of the player, which would be odd..

I have a background application that has a System.Timers.Timer running in it.When the elapsed event is raised I want to show a form.Now if I call form.showDialog everything is hunky dory. If I call form.show the form is not responding ... Now I suspect that this is happenening because the elapsed event is raised on a secondary thread but that said I dont know how to fix this.

All the code needs to be controled by seperate timers as the user may need to pause timer3 or timer4 at any one time. The problem I have is that after about 5 minutes the time and elapsed time are about three seconds ahead of the two count down timers.

I'm developing an application to learning purposes only. The application will check some proxies that are in a proxy list.
I did a For Each loop ( to run all the proxies in the listbox ). The problem is some proxies are slow to answer and I must do the application wait some seconds before get the next proxy.
I tired a sleep thread but I don't want the application to be unanswering. There's any chance to help me with the timers?
I tried all possible ways and searched a lot but my problem is each time the timer ticks, it make the full for each loop again instead waiting.

I am using vb 2008 I am trying to learn loops and timers but I have some problems. [Code] The problem with this is it does not wait it just sends 123 all at the same time. I tried using the other way the one that makes the program freeze for the amount of time I want it to wait, but I don't want the program to freeze I want to to move my mouse ext whilst its doing it. as for the loop this is as far as I got I cant really test it yet cos my program is typing 123 a million times a second and my pc doesn't like that so i need to fix the timers.

I created a timer in the main form - form1 which then updates some text in form2 each 100ms. Now When I click a button in form1, the timer stops. Why? Happens no matter if timers are on or off by default. I have to open/close form2 to make my status updates work again - that's where I run the timer on form load and stop the timer on form close.
Was doing it in windows 2010 express.
So this is what I have in form1:
Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'some stuff
