Javascript - Make A Countdown Timer In Web Application(C#)?
Nov 11, 2010
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.
How do you make a Countdown timer? When the user loads the page, clock starts counting down, it reaches time, it redirects browser to a new page.Found this, it was not too useful.
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?
The project requires days/hours/minutes/seconds so if I could grab the exact time the page was requested from the server I could then just through it in a JavaScript variable and work it out from there.
i added a countdown timer to show seconds before page gets refreshed. But every tick counts 2 seconds instead of 1 .. so it goes from 30 > 28 > 26 instead of 30 > 29 > 28 ..
On page load I set the label value to 30.
The update panel contains following code for 2 labels and timer:
[Code]....
Code behind:
[Code]....
There is another timer on the page that forces a refresch every 30 seconds:
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 want a browser to go full screen as soon as my page loads. Is it possible in javascript. I know the shortcut key for this F11 but requirement is on page load only.
After reading the solution provided below. I achieved full screen but here i got a trap. I was using timer to make my page postback to get fresh data after every 5 second. And here I found after every 5 sec new window opens up but I want full screen to go only once and next time content gets refreshed there itself.
First of all, I'm sorry if I don't describe my problem so well, English is not my first language. I'm working on a project where after the user has pressed a button, the button goes invisible and a label control should say "In 20 mintes you may press the button again". The problem is that if the user presses the button before the current hour is almost over, then he will be able to press the button again. The way I compare the time is by placing th current time, which the user presses the button in a sqldatabase table row for that user. This is my code for the moment for showing the user how long he has to wait:
DateTime TimeSincePressedbutton = Convert.ToDateTime(user.timeSincePressedButton); //value from database TimeSincePressedbutton.AddMinutes(20.00); TimeSpan d = DateTime.Now.Subtract(TimeSincePressedbutton); int dd = Convert.ToInt32(d.Minutes); int timeLeft = 20 - dd; ValPointsTitle.Text = "In " + timeLeft.ToString() + " minutes you may press the button again";
and the code I have for comparing time with the time now, is to see if the user may press the button again (which I know is wrong, just cant figure out how to fix it, the reason I compare hour, day, month, year etc is because if the user doesnt show up online the same day, maybe he comes back after a couple of days, or next month, or next year).
if (timeLeft <= 0 && DateTime.Now.Hour == TimeSincePressedbutton.Hour || DateTime.Now.Hour > TimeSincePressedbutton.Hour || DateTime.Now.Day > TimeSincePressedbutton.Day || DateTime.Now.Month > TimeSincePressedbutton.Month || DateTime.Now.Year > TimeSincePressedbutton.Year) { //button becomes visible and the user may press it again }
I am looking for a way of graphically showing a countdown. I am working for a large Hospital and have written an Ambulance page that shows ambulance arriving in a datagrid with the time of arriving at the hospital in minutes and seconds (plus other info).They have asked me for somehow visually representing the information, so it fits with there other visually appealing Emergency Department web application (e.g. progress bar or something better):1) Can somebody show me (visually appealing) design examples on how this could be done2) Are there solutions in .Net (ASP.net or JQuery or Javascript) since this is our preferred technology
I have a gridview on my page. I want the page to show me next 10 records after every 10 seconds. i.e. automated paging.I have implemented manual paging on Gridview. How can I do this using Client Side event triggering
I have created an application in asp.net using c#.In that i have a Quiz Module.Quiz is working fine but now clients wants a Timer in this Module.How do i add a Timer for two minutes for whole quiz which will be showing like this- > 02:00 to 00:00 ?
I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes
a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I haven�t put here.
But what does not work is the code I have in the Page_Load event now.
I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");
This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.
But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve 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.
I have an ASP.NEt website and I want to know how can determine how long the website was idle (no activity from the user) and then based on that timer I want to automatically logout and redirect to default.aspx?
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.
