Two Different Timer Variables In The Same Code Firing At Different Intervals?
Mar 31, 2011
I have created a windows service and I have two different timer variables in there. 1st one fires off every 5 seconds and then does whats it is required to do. The second one fires every 30 seconds.
I make sure that when the function are getting executed I disable both the timers and enable once the function is complete.My problem is my second longer (30 second ) timer never fires only the first one is firing. I had created this service 3 months ago and it was working fine till now. But now I do not see the timers work properly in a simple windows app i created to test their workings.
I decided to whip up a simple stopwatch-esque timer for some needs of mine. Well after writing a very basic code for the timer to show seconds and milliseconds I see that the intervals are wrong[code]...
I'm trying to make a form that will read my wordlist. txt (one word or phrase per line) then using a timer, insert one word randomly selected from the list, and display it in textbox1 where it will remain until another timer changes the word. The word in the textbox will display for a random time 1min to 7 min, then the textbox displays another word randomly selected from the word list.
I am looking to create a 500ms timer that I can use to make some text flash.Setting up the timer is straight forward enough, but I have not found an example of letting the timer create an exception so I do not have to poll it for a timeout.
I used a timer in my user control now when Timer_Tick event is fired I want to raise an event like Ticked. I created:
public delegate sub myDel() public event myevnt as myDel 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.
I have a Windows Service -which contains a System.Timer -which get enabled and started in the OnStart event handler.In the Timer Elapsed event -I make a call to a routine within another DLL. The problem is that the Timer Elapsed event never fires... I have a test application -which works fine. This is written in VB.Net 2008 framework 3.5
I am a newbie, but I am unable to get this code working. FileSweeper is supposed to start a timmer that triggers fileCopy on a web server. fileSweeoer is triggered by global.asax.ileCopy then will copy the filWould it make any difference if this was a class running on a web server?
Imports Microsoft.VisualBasic Imports System Imports System.Threading
When I run the following code in the UI thread, it works without issue.
VB.NET private timer as new timer public sub test()timer.enabled = true timer.interval = 1000 timer.start()addhandler timer.tick, addressof timer_tickend sub private sub timer_tick(...) messagebox.show("fff")end sub
But if I run it within a background thread, nothing happens.
Im currently writing a sort of Tamagotchi game or "virtual pet". It's really basic, it runs on timers and has a health meter, hygiene, happiness etc. The problem I have is when the program is closed it obviously resets the properties back to the origional settings. Is there a way I can save the state of the program so when the user opens it back up it is as the same as of the point when it was closed?[Just had an idea, would I set a timer to periodically save the value of the variables to a database and then have them load the next time the user opens the program, for example if the health was 50% on closing or at intervals it would save the health into a column in a db table then when the user re opens the program call that db?]
i have a project with 1 main form, in form load i call 4 subs which call data from an api. I have added a splashscreen from the add form menu. The splashscreen displays first while the main form loads(calling api data)What i would to do is have a progress bar on the splashscreen with the progress of the mainform load.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SplashScreen1.ProgressBar1.Value = 0 updategeneral()
Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?
I would like this ASP button control to stop calling its event handler when the JavaScript client method IsCorrectPrice() returns false.
<asp:Button ID="btnsubmit" runat="server" Text="Submit" OnClientClick="javascript:IsCorrectPrice()"/> btnsubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnsubmit.Click
I have an asp.net app that launches a modal window upon button_click event. That modal window launches another modal window upon another button_click event.
However, the final modal window's "Page_Load" event is not firing.
The second modal winodw is called via a javascript call from vb.net code behind Page.ClientScript.RegisterStartupScript(Me.GetType(), "Script", "ShowModalWin('brPreview','brPreview')", True)
As the subject describes, once I implemented support for DragDrop - The DoubleClick event of the ListView control no longer fires.An overview of the code is as follows:
Private Sub ListView_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView.MouseMove
I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?
I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
I some code that looks to see if a certain program is running when the form is open. If the program is open it puts Running in a label, if it isn't running it says not running.What I want to do is repeat this process every 5 or 10 seconds. I have never used a Timer before so not sure where to start.
I am trying to implement a progress bar into my code but it seems to not run when another section of code is running. I set a timer to run when the ok button is clicked and it should then start the progress bar but also when clicking the ok button whatever radio button is selected also runs. I am trying to do this in Visual Basic 2008. I will post my current code below and I will say I am a complete novice at this so I apologize if the code looks weird:
