I have a from with various timers. what is the code to turn off all timers in a form at once?
i all ready tried:
For Each crt As Control In Me.Controls<br/>
If TypeOf crt Is Timer Then<br/>
crt.Stop()<br/>
End If<br/>

Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.
CODE:
When a dialog form opens, does all code and timers stop until it is closed?
View 19 RepliesI have a simple application that use thread pool to read a file and input the data into a listbox. I want to be able to stop threadpool from running after clicking a stop button. How do I stop threadpool? Here is the code for my application below:
Imports System.Threading
Public Class Form1
Private Delegate Sub StringDelegate(ByVal text As String)

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

is it a good coding practice to keep timers in a project to a minimum, or does it not really matter?
View 1 RepliesI have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?
how can I place all timers on a form into a collection

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.
basically what im doing is something similar to this;
Private Sub FirstRoutine()
'This is my first routine, i load a listbox up with a whole

I have the system tray icon changing pictures based off a timer..and when I check my page faults they go up on every tick ofthe timer.. so then I pull out the changing of the picture thinkingthat was it.. but still page faults increase..so just wondering if timers have issues ?this was a timer from VB6 ? is there a new timer I should use from.net.. delete the old and use a new control ? I have a couple sobefore I switch them all out.. figure I would find out first..

View 5 RepliesI 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.

View 7 RepliesI 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

View 4 RepliesI 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?

View 12 RepliesI'm considering making an application that will perform various tests against servers on a local network - for example pinging them, checking hard drive space, checking the state of services, whether or not databases are available, etc etc. Very similar to Hostmonitor if anyone has ever used that - but my app will be free
These tests would have to be performed at specified intervals, but the problem is that there could be literally hundreds of tests and I'm not sure how well my app would cope with hundreds of timers running... especially if they are all configured to run every minute or two (they all need to run independently of each other).
Really I'm just wondering how you guys would design such a system.The best way I can think of is to have a separate timer associated with every test and then when a test's timer has elapsed use the ThreadPool to do the work that the test will perform. That way if loads of them happen to run at the same time then the ThreadPool will queue them rather than trying to run say 200 at once. I also think I would need to have some kind of staging for when the app first starts, so that every single test is not going to have the exact same time to run (well, every test that has the same interval configured), but that shouldn't be too much of an issue.I guess it would be a good idea to try and use some sort of grouping so that more than one test can use the same timer - like if 20 tests were set to run with a 5 minute interval then I could use one timer and run all of the tests when that one timer fires.
I want to expand it a little bit and add a second timer that runs parallel to the first timer, but is not affected in any way shape or form by the first timer.
Ive tried nesting the second loop in the first loop but the second loop takes 3 seconds to complete (I use thread.sleep(3000)), so I found that it froze the first loop till the second loop finishes. I was reading about system threading (System.Timers.Timer) and it seems like that is the route I want to go.
I wrote this quick as an example:

I cant use the timer1 to set off the second round of events because of the thread.sleep. I was hoping that the code above puts the second thread to sleep while the windows.form.timer continues on ticking every 1000 ms
Is there any way to check date and hour without using two Timers?
Right now i have this for the date:
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Timer1.Stop()

PS (again): I thought about setting the Timer1 interval to 60000miliseconds, so that it would check the time everysingle step of the way (or maybe 10 minutes...), but I don't want the app to lag, so... How can i implement a Background Worker?
In my class, we are designing a concentration game. The game will give you and output of numbers and you will have a specified time to memorize the numbers. Then, you will enter your guess to see if you were right or not. User will have the option to specify if they want a 3, 6, 12, or 24 digit number. Then they will be able to specify their own timer of 30 seconds, 15 seconds, 3 seconds, or 1 second. The options are done using radiobuttons.Groupbox 1 categorizes the number of digits long. Groupbox 2 is for the timer. So far, I have the whole game layed out except for the timer. Everything works.
