What is the value you are getting in r(string)? It may not be a integer thats why you are getting the exception.

i can give you a idea.
when a user is logoff you application that time you have to call a another form (like "logout.aspx" )for stoping in to user go back.
now you can write a javascript on Body tag window.open(index.aspx");
wirte in Header Tag
<code><javascript>
function logout()
{
window.open(index.aspx");
}
</javascript></code>
call this function on body load.
<big><b><body onload="logout()"></b></big>
i thing this is very help full for you.!

Hi All
I need to generate multiple line charts dynamically using ADO.NET data in ASP.NET 1.1 application.
If anyone can provide me a link to some example code to handle line charts. By "line
graphs" means,graphs that have dates on the X-axis and data on the Y-axis in several colored lines .
I'm limited of not using any readily available graph tools/controls.
The Graph with features i'm looking to generate will look in the manner as available in this link below:
(http://finance.yahoo.com/charts) or (http://finance.google.com/finance?q=CSCO)
Thanks in advance

I have a question regarding keeping a username in the cache in order to
prevent multiple logins. I read 'Preventing Multiple Logins in ASP.NET' by
Peter Bormberg (great article
http://www.eggheadcafe.com/articles/20030418.asp) and everything works fine,
however, I think we are going to have problems from our users having to wait
for their cache to clear out before they can login again. Is there a way to
clear the username out of the cache when they logout? I seem to be missing
something here.

You can remove the cache by using the Remove method
Cache.Remove("MyCachedItem")
Hope this may help u out of your problems.

I tried to display images from a database in to a datagrid....
The images are coming one below the other.
I would like to display images as 4 rows and 4 columns in a page
and the rest of the images in another page..
In a datalist it is possible but there is no paging in datalist..
so i cant use it..
the code i have written
<asp:datagrid id="DLFotos" runat="server" cellpadding="2" cellspacing="2" allowpaging="true" autogeneratecolumns="False" pagesize="3">
<columns>
<asp:templatecolumn>
<itemtemplate>
&IdPadre=<%# DataBinder.Eval(Container.DataItem, "IdPrenda") %>"><asp:image id="Image1" runat="server" borderwidth="0">
Please Help....
Thanks in advance

I think datalist will better suit for your requirement. And for paging you can implement custom paging with the datalist.
