Ajax - How To Call A Function Automatically After A Certain Time Has Elapsed

Jan 19, 2011

Let's say I have a Label on my page. In PageLoad() it's Text parameter is set to "This is my first text".

After, for example, 1 minute I want this Label to change it's text parameter to "This is my second text" (completely automatically, without any interaction of a user with this site).

SQL Server :: Using Datediff To Calculate Elapsed Time?

Sep 3, 2010

my app requires an elapsed time calculation that I have done like this

CONVERT(Varchar, (DATEPART(dd, GETDATE() - DateAdded)-1) * 24 +
DATEPART(hh,GETDATE() - DateAdded)) + 'h:' + CONVERT(Varchar, DATEPART(mi, GETDATE() - DateAdded)) + 'm' AS ElapsedTime

This works.. I can then colour my grid view cells accordingly using the substring function.. the problem is that I have been told that using GETDATE three times is not a good use of resources, is it possible to use the Datediff function to get the same result?

C# - How To Find The Elapsed Time Between Send And Receive Data

Feb 28, 2010

I am using the System.Timers.Timer class. And I enable when I send a message and disable when I receive the message. How do I calculate how much time has elapsed. I have set the interval as 1 sec

Basically I retransmit data after 1000 sec again if I do not recive an ACK. I retransmit 5 times max until I get a Ack. If I receive and something before 150ms then I stop retrnsmission.

Here's the code:

timer1.interval = 1000;
port.Write(data)
timer1.enabled = true;

event handler for the received data.

Web Forms :: System.Web.UI.Page.ProcessRequest - Elapsed Exclusive Time

Jan 28, 2010

We have an ASP.NET web app talking to WCF for data. After resolving a number of service and db level performance issues, we turned to look at the web app itself.

After running a profile while hitting a few common pages, ProcessRequest is at the top of the list as far as elapsed exclusive time (which means time just in that method and any kernel code if I'm not mistaken)

Function Name
Elapsed Inclusive Time
Elapsed Exclusive Time
System.Web.UI.Page.ProcessRequest(class System.Web.HttpContext)
31,573.64
17,915.56

Viewstate sizes are not severe, prob 60k at most for fattest page.

MVC :: Call Ajax.ActionLink From JavaScript Function?

Unless that can be made to populate at runtime, on demand from a script. manually clicking the ""Load Menu" ActionLink works exactly like I want except it requires the user to click the link; I want to do that for them... in this case from the Body onload event.

Javascript - How To Use MS Ajax PageMethods To Call A Function On The Server

Jan 16, 2011

I have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured

"WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON."

Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example:

function OnRequestComplete(result,
userContext, methodName) {
var Person = eval('(' + result + ')');
alert(Person.Forename);
alert(Person.Surname); }

So is the first technique is correct? or what?

P.S:

the function on the server is defined on the default.aspx.cs file as follows:

[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] Foo(string s);

from the client side the calling is as follows

PageMethods.Foo("value",OnSuccess);

Also all the users have the same browser version (IE8)

VS 2013 - Call Web Service Function Within (Code Behind) Using AJAX On Page

Dec 4, 2014

I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.

Once i push the button to execute the JS/AJAX/codebehind - I got an error.

POST http://************/admin/Admin.aspx/getDBInformation 500 (Internal Server Error)

This is my code below that I am currently using:

Code:
<WebMethod> _
Public Shared Function getDBInformation() As String
loadDBData()
Return JsonConvert.SerializeObject(dbInfo, System.Xml.Formatting.Indented)
End Function
End Class

The code behind looks like this:

Code:
Imports System.DirectoryServices
Imports System.Security.Principal
Imports System.Net
Imports System.Drawing
Imports System.IO
Imports System.Data.SqlClient
Imports System.Web.Services
Imports Newtonsoft.Json

[Code] ......

How can I correct this issue so that I am able to call **loadDBData()** without that 500 error?

Ajax Javascript Function Taking Too Much Time

May 20, 2010

We are using asp.net ajax 1.1 (and can't upgrade to latest for internal known reasons). We are having a page where we call ScriptService method through ASP.Net ajax and oncallback of result, we bind that result to Html controls on the page. During testing we observed that this whole process is taking too much time. When we profiled using IE8 developer toolbar, we observed that there is one standard function from ASP.net Ajax frameworks' own JS. Function name is function$_validateParameterType and it is the one which takes maximum time amongs others. Is there any way we can reduce the time take by this. Is there any standard practice for such requirements.
