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.

Have you tried a template column with a table in it to format your pictures?

Hi,
I have a question regarding breadcrumb...
I have 3 pages say page1, page2 and page3.
i have added breadcrumbs on all pages and its working fine but i need to show all the nodes of breadcrumbs in all pages (like this page1>page2>page3) so that i can move forward or backword from the breadcrum e.g. if i'm on page1 then i want to show breadcrum like this page1>page2>page3 and other page2 and 3 will be a link but not page1.
is it possible with asp.net 2.0 sitemappath control? if yes then how
|
|
|
|
|
If you want it to be the same on every page why use the sitemappath control at all? Just put them all in the master page and roll with it. I doubt its an option because sites are rarely linear and you would need a tree to map the site backwards as well as forwards.

When do you think that it would fire, and what is your code doing?
Why I'm asking is that in most cases when this question comes, the person don't know how the even works, or is trying to do something that is not possible at the time when the event does fire.

Hi there,
I'm trying to change a password in Active Directory using C# & ASP.NET, I've tried 2 ways but can't get it working.
Method 1
---------
The conn.SendRequest() method raised a DirectoryOperationException (the server is
unvailable). However the server is available.
try
{
LdapConnection conn = new LdapConnection(serverName);
conn.Bind(new NetworkCredential(userName, currentPassword, domainName));
DirectoryAttributeModification deleteMod = new DirectoryAttributeModification();
deleteMod.Name = "unicodePwd";
deleteMod.Add(GetPasswordData(currentPassword)); //encrypt
deleteMod.Operation = DirectoryAttributeOperation.Delete;
DirectoryAttributeModification addMod = new DirectoryAttributeModification();
addMod.Name = "unicodePwd";
addMod.Add(GetPasswordData(newPassword));
addMod.Operation = DirectoryAttributeOperation.Add;
ModifyRequest request = new ModifyRequest(userName, deleteMod, addMod);
DirectoryResponse response = conn.SendRequest(request);
conn.Dispose();
}
catch
{
throw;
}
Method 2
--------
de.Invoke raises a DirectoryServicesCOMException (an invalid dn syntax has been specified)
string strADSIPath = @"LDAP://CN=username,DC=companyname,DC=net,DC=au";
DirectoryEntry de = new DirectoryEntry(strADSIPath);
try
{
de.Invoke("ChangePassword", new object[] { currentPassword, newPassword });
de.CommitChanges();
}
catch
{
throw;
}
de.Close();
I can't work it out, any help would be greatly appreciated,
Cheers,
Ron.
