Yes i am sure it doesnt work even after 20 minutes after that last request.I have added the element:
<sessionState mode="InProc" timeout="1"></sessionState>
to the web.config file but the Session_End doesnt execute and the Session_Start executed when i refresh the page after one minute after last page request..

What code have you put in Session_End, and how did it lead you to the conclusion that it doesn't execute?
---
b { font-weight: normal; }
|
|
|
|
|
The code just decrement a number(a static member in the global) and send an email to me:
EProjects.AdministratorSite.SessionTracker tracker;
tracker=new EProjects.AdministratorSite.SessionTracker();
Application.Lock();
--m_ActiveUsers;
Application.UnLock();
EProjects.AdministratorSite.MailUtil.SendSessionEndAlert(tracker);
"I am too late but i will never give up"
|
|
|
|
|
What does the tracker object do? Are you sure that it can be created in this environment?
Decrement the number before you create the tracker object, in case that causes an exception.

b { font-weight: normal; }

Well I used the code in the following article to create the tracker object:
http://www.15seconds.com/issue/021119.htm[^]
But the WebSite Visitors number is independent of this article and depends only on the static int member that is incremented in the Session_Strat and decremented in the Session_End .
"I am too late but i will never give up"
|
|
|
|
|
The very first thing that the constructor of the tracker object does, is to try to get the context for the current request. As the Session_End event isn't run as a result of a request, there is no context, so it will only get a null reference. When it will try to use the reference, that will result in a null reference exception.
It's as I suspected. The Session_End is executed just fine. It's just the code that you put in it that doesn't work.

Sorry for being late..You are right about my mistake:create a tracker object in the Session_End Handler:
tracker=new EProjects.AdministratorSite.SessionTracker();
But I have modified the code to:
tracker=(EProjects.AdministratorSite.SessionTracker)Session["Tracker"];
Like the article code but I got the same result(nothing happend).
I made a test for the Session_End by writing a code that only send a simple message using SmtpMail.Send() and nothing happend too...
Then I made another test by removing the sessionState element and nothing happend too.
May be because I deal with a Web Hosting Server(Iam not the Web Server) there is something different I dont know what is it?!

The SqlDataSource control only supports a single view, it means you cannot use a single SqlDataSource object to return multiple result sets. Instead, you can use multiple SqlDataSource objects, or write code to return a single dataset object having 3 difference tables and bind it to the dropdownlist controls, also you remember to set the DataMember property accordingly.

Hello All,
I have a <b>datagrid</b> control on webpart, in which I am displaying two out of six columns from a dataset. When somebody click on one row, I want to display all six values for that row on the same webpart without postback. i made this datagrid clickable. i m passing value using the following code.
public void dgSpeakerEvents_ItemDataBound(object sender, DataGridItemEventArgs e)
{
if(e.Item.DataItem!=null)
{
e.Item.Attributes.Add("onmouseover","this.style.cursor='hand'");
e.Item.Attributes.Add("onclick","ShowDetails('"+
DataBinder.Eval(e.Item.DataItem, "TOPIC_NM").ToString()+ "','"+
DataBinder.Eval(e.Item.DataItem, "CITY").ToString()+ "','"+
DataBinder.Eval(e.Item.DataItem, "STATE").ToString()+ "');");
//e.Item.Attributes.Add("onmouseout", "HideTooltip();");
}
}
but when i clicked on datagrid, it shows an error: object expected. i checked in the html source code generated by the browser, values passing correctly.
my javascript function is :
<html>
<body>
<div id=Popup class='transparent'>
<div style='background-color: #003366'>
<b><center><span>VenueDetail</span></center></b>
</div>
<div><table width=100% border=0 cellpadding=0 cellspacing=0>
<tr><td id=td0 align=left class=runtext></td></tr>
<tr><td id=td1 align=left class=runtext></td></tr>
<tr><td id=td2 align=left class=runtext></td></tr>
</table></div>
</div>
<script language=javascript>
function detail()
{
function ShowTooltip(name,city,state)
{
document.getElementById('td0').innerText=name;
document.getElementById('td1').innerText=city;
document.getElementById('td2').innerText=state;
X=event.clientX+document.body.scrollLeft;
Y= event.clientY + document.body.scrollTop + 10;
Popup.style.display='block';
Popup.style.left = X;
Popup.style.top = Y;
}
}
function HideTooltip()
{
Popup.style.display='none';
}
</script>
</body>
</html>
If any body can suggest me with good example.Thanks.

First you should display all the six columns in the datagrid and hide the columns that you don't want to be visible using e.Item.Attributes.Add("display", "none") in datagrid_ItemCreated event. This will ensure that the specific columns will be present in the aspx page, but not visible to the user. You need them to be present in order to be able to show them without a postback.
Then, add a control to the webpage where you will display the hidden columns when the user clicks on an item.
When the user clicks on an item call a javascript function that will read the values from the specific hidden columns and display them in the control.
Your code above for clicking on an item in the datagrid is not correct. Adding an attribute to the datagrid will result in calling the javascript function when the user clicks on the datagrid, and not an specific item in it. You need to add an attribute to each item in the datagrid. See this article[^] as an example on how to create javascript events for items in a datagrid.

Hi all

You can't automatically save the file on the users desktop. The best you can do is provide the dialog which prompts for saving the file.

In ASP.NET 2.0, you can use the FileUpload control.

Hi Developers
I watermark an image dynamicaly using VB.net. It was great to seee my company's logo on Product Images BUT I was amazed to see that Watermarked Image size increased almost 10 times.
Original Images Size =60KB
Image size after watermarking=557KB
Image format is .jpg......What I think is that the original image is first converted to Bitmap and then its Watermarked, but its not compressed to .jpg format after watermarking.
Please suggest me anything regarding this, Thanks

Hi Developers
I am trapped in a serious problem. I have developed a site for online Automobiles sales/purchase. You may heard about Autochek which take the VIN(Vehicle Identification Number) and give you the entire history for that Vehicle.
I want to integerate this with my site. The problem is that autocheck provides information about vehicle only if the "request made from the IP of our site". In short i need that Request should be made from website's IP not from client IP.
Thanks in advance

Use a HttpWebRequest object to request the data from the server code, then present it on the page.
