You can use session("varname")=null; to clear the session

Hi
Session object in ASP.NET implements ICollection interface
So Session has a method
Session.Remove("entityName") ;
to remove all the items in Session collection one may use
Session.RemoveAll();
Session.Clear();
P.S.

how to develop spam filter application using asp.net with c#.net
plz help me
|
|
|
|
|
You probably need to have the list of spammer ip addresses in your database or need to use the third-party service for that..
|
|
|
|
|
ASP.NET is not an appropriate technology to use here, unless you're writing an app that reads mail online. Otherwise, why do you need web pages to filter spam ?

Seems to me that you're just asking for grief. Why not install MySQL on the Windows machine ?

Hi....
I want to Create drive on own server..Just Like Gmail Drive
|
|
|
|
|
What do you mean by "creating a drive"? Virtual partition or ??
GMail Drive is the same as GMail (but with filter). So, All files that you store in GDrive is actually stored in GMail Mail Server. So, If you want to do that, just host the Email server with larger maximum attachment size. then write another client application like GDrive that fake users not to know whether they are sending a mail or transferring the file.
Anyway, I don't think this is a good idea.

hi,
i have a dagrid..in that checkboxes are there with ids of 1,2,3;
i am passing the ids to that grid are 2,1..accordig to my logic those checkeboxes(1,2) has to be checked =true
for ids 1,2 it is working
if i pass the 3,2 then only 2nd checkbox is checking
if i pass the 3...then no checkbox is checked...
last checkbox is not checking for the last id..
i wrote the code like this in the databound event
strScheduleIds=strScheduleId.Split(',');(here the values i am getting which i passed from the otherpage .)
for(i=0;i<strScheduleIds.Length;i++)
{
foreach(DataGridItem dg in dglist.Items) {
if(dg.Cells[9].Text.ToString()==strScheduleIds[i].ToString()
) {
((CheckBox)dg.FindControl("chk1")).Checked=true; }
}
}
|
|
|
|
|
Have you tried to debug your code? strScheduleIds.Length - 1 in first for-loop?
Are dg.Cells[9].Text.ToString() and strScheduleIds[i].ToString() the same if you pass "3"?

Yesterday i post this query.First of all sorry to post it agin.
The above code is to get the unit id checking with the userid.That means if the user login had the particular unitid.I want to chk that.If the use had login had no unit id thn an exception in sql is displayed.The exception is object reference is not set.How i overcome it..Laos i attach the checking functinality itself with this mail.Please help me to overcome the pbm....Thanks

change your logic, if your GetUnitId method doesn't have any record then it should send something which shows that it return null.
Push your brain and it will work out for you

Hi
I am trying to create a page that when I access it using the Internet Explorer, the page will not load, and in the Internet Explorer's status bar, the status will be "Loading".
(I need it to create tests for my systems)
I tried to add Thread.Sleep(1000000) on Load_Page event, but then the IE froze and the status was "Connected"
I also tried to add the frame tag. and in it i called another page, but for some reason it didn't get stack at all.
Can anyone help me?
thank you in advanced,
Daniel
ASP page that stacks on status loading
