I want to add a countdown timer to my page. What happens is when the user presses the 'Process' button it goes out and performs various tasks and displays results to a listbox. I want to add a 10 - 1 countdown timer so the user knows its actually moving. Once it gets to 1, I need it to start over from 10 until it is finished.
So I'm creating a countdown timer for a project I'm on and I feel its important to get the most accurate time possible. I figure; what is more accurate... and more importantly the most unalterable than server time?
i am using vb.net i am doin an online exam....and i want to apply a timer countdown when the exams starts....this is my code...i have used a asp Timer with ajax enabled
Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Session("sec") = Session("sec") - 1 If Session("sec") = 0 Then Session("min") = Session("min") - 1 Session("sec") = 60 End If Label1.Text = Session("min") Label2.Text = Session("sec") End Sub session("sec")=60 &session("min")=5....ie for 5 min exams..these session variables are initialzed in the previous page....
it works fine BUt i have many buttons in my exam page for submiting answers,moving to next page etc....if i click any of the buttons the timer stops for a second..if i click any button continously the timer stops till i stop clicking the button....how can i keep the timer countdown working without any stopping...even if i click any buttons on the exampage.. or is there any other better solutions to make an timer countdown...
I am Creating Timed online test in C# asp.net.I have created it using the local machine time. But in the case of Database disconnection or system hang, The countdown timer must start from the time at which the machine has hanged or unexpected database disconnectivity.For example the user is answering the Questions for 10mins and unexpectedly system hanged. After recovery the countdown must start from 10mins. Can anyone please help me with coding in C#? I have used the following coding, But its not useful in the above scenario.
I am a newbie and have designed a website using ASP .Net 2.0 with C# 2005. On the home page I am displaying rates of a few items which gets updated every 15 minutes. The new rates are entered through a different web page into a SQL Table and I am using Page Refresh of the home page to update the rates every 15 minutes. Everything is working ok upto this. But now I have to display a countdown timer of time remaining for the next update on the home page. I am totally clueless as how to approach the problem.
I'm searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.
I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.
I have an ASP.NET form with several update panels. All works great.I use a timer and have it handle some periodic upates. That works correctly too. However, I appear to get an error when I leave the page open running in the debugger. Specifically the above JScript error 12030.I'm not clear how to find the source but I assume it is because my page has logged out. If I refresh I go back to my login page.So, does this sound like the cause? If so, how to I address this?
VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.
For two days now I try to produce a simple timer. To do this a use Visual Studio 2005, I installed .NET 3.5 (should include AJAX?).
Then I follow the tutorial:
I make new ASP.NET website (can't choose AJAX web site). I put a ScriptManager on this site. Then I add an UpdatePanel and insert a Timer INSIDE the Update Panel. I also add a Label. I double-Click on Timer1 to create the Timer1_Tick and write the code in the timer. I set the timer to 5000ms and try to run the page.
But the Timer1_Tick is never activated. Here the code:
To debug I use Firefox 188.8.131.52. The Webpage has no errors. When I put this project to IIS6 and open it with IE6 there are errors on the page: 'sys undefinded'. But I regard this problem as a different one.
I have the following simple code for executing a long running task
Code works fine in IE, Safari. In FireFox, it doesn't work after I refresh (clicking the refresh button or press CTRL+R or only F5). It simply doesn't get to the timer_tick event. It does work when I press CTRL+F5.
I made a very simple pannel updating wich will query a database and show a message on masterpage through a label.
Thus, I've put an updatePannel with a label and a timer within (obviously with a scriptManager) in my site's masterpage.
However, when I try to interact with the timer1 object, I receive an error message: "object not set to an instance of an object". I not receive this message when placing the schema in a blank page (without masterpage).
I must to run the query in masterpage because the users need to receive information whatever they are in my site.
How can I correctly place the components to do this work? what I'm doing wrong?
have an application which runs in the offline environment and populates the MS SQL Server 2005 database. By one of our process we do the incremental update to online (web) database.Now the problem is that by clicking the button to update the online database it take 15 to 20 minutes to and the user have to wait until the complete postback process complete.The grid that contains the information (about the updation of database) will be refreshed after the complete postback but we want to refresh it as by a particular items (i.e. table of the database)How can i do it ??
I'm trying to create a 2 second Delay before I initiate a File Download Link.
The problem is, it all works but once the Save Dialog appears, then Timer is supposed to TURN OFF. But then it keeps on calling Page_Load event again, which enables the timer. So it keeps sending/showing the File Save Dialog constantly in a loop.
The thing is it seems to work when I test it on the Development machine, but when uploaded on the server it goes back to a loop.
I have this to try & prevent the loop:
Basically its a label which holds the full URL once its initialised. But empty on form_Load.
If Not lblFileURL.Text = vbNullString Then Timer1.Enabled = False Exit Sub End If
How Do I prevent this. It is a PostBack problem I believe.
here I'm using a timer control to increment count variable. When I run it on the browser, it shows 1 every time when a timer ticks it's not incrementing can any body tell me why this is happening.Here is the code..
I am doing a countdown with a timer that runs every second. I have a scriptmanager, but how do I make it update behind the scenes so the user does not see it? I thought I could use an update panel, but I can't get it to work right.
I am using ajax timer outside update panel Timer_tick event fired twice after every 5 secondsMy Issue is why it fires twice after 5 secondsI know the interval its my setting like (interval=5000)but why it fires twice together thats why my application get hanged???
I am currently working on an ASP.NET project, where I am using C# as my default language. I have an .aspx page, where I have an AJAX Script Manager and an AJAX timer. When that page first initializes, it does a pretty costly operation (parses a .csv file), which I only need to do once. However, every time the Timer tick takes place, Page_Init is fired again. Is there any way to correct it?
To avoid that users get logged out when they haven't been active for a while, I am using a Timer-control to make a request periodically before the session times out.
My problem is that even though it is not shown (which is good), the entire page gets sent back to the client on each "tick" (25k or so, shown in Fiddler) and even if this is not really a problem, it would make me feel a lot better if less data was returned (since I am really not doing anything anyway). I am using this code in my masterpage which all of my pages use.
Code on the client side:<atlas:ScriptManager ID="ScriptManager1" runat="server" [code]....
When a new item is inserted I want to show a message like "Successful" for 3 seconds and then redirect to main page. For that purpose I used timer control. It works fine in IE but not in firefox. Below is the tick method:
If that is even the right combination of controls to use.. I have a page that will display a list of files that have been processed or processing.. its not really time sensitive, but would like for the page to refresh the gridview every say every minutelonger(not determined yet)Is that the most optimal way to accomplish this, i mean if you are on the page, i dont want you to have to hit refresh to see any new records or status changes to the existing records..
