- ASP.Net >> Asymmetric EncryptionHello everybody..
I hav some confusion regarding asymmetric encryption.As asymmetric
encryption it there is one private key and one public key.So any data
is encrypted using private key and the same is decrypted at client side
using public key and vice-versa..Now i hav confusion like i.e.
* Are both the keys available to both sender and receiver.?
* When data is encrypted using public key ,Is the same data decrypted
using private key( at client side).?
* How the keys are send to the client/receiver of message..I mean are
they assigned to browsers or they are validated or send depending on
login id/password of a user.?
*If possible kindly explain (in-short) the whole process of assymetric
encryption.!!!plz
Thanks & Regards

- ASP.Net >> Adding Validation via OnItemDataBound event (ASP.NET 2.0)OK, I am running into some issues that I cant figure out a work-around.
I am not going to post code cause I figured out WHY my issue is
happening:
-I have a datagrid, and a button that fires a click event.
-The Datagrids onitemdatabound event dynamically creates validation
controls per values from other columns in the datagrid, one of those
controls is a textbox and it is the ControlToValidate of the validation
control.
ie - Basically, think of a shopping cart with a quantity textbox and
another NOT visible column for inventory. During onitemdatabound I
check the inventory (tempInventory = e.Item.Cells(1).Text) and create
the necessary validation for Qty.
Everything works great with client side validation, the problem starts
when I attempt to process validation server side.
When my button with the click event is fired, Page.IsValid is always
true. BUT, when I move the validation control creation to the
OnItemCreated event, it all works fine.
My problem is that the validation relies on data, which OnItemDataBound
has not fired yet for that item.
Any ideas? In theory, I am thinking of creating the validation fully at
itemCreated, then disable and change validator properties at the
itemdatabound event if applicable???? I don't know if that will even
work.

- IIS >> WIN XP PRO HOSTING MULTI WEBSITES IIS 5.1I want to host 2 websites on my win xp pro box using default IIS 5.1. I am dumbfounded at how IIS knows which root directory to use when it receives a request for webpages. I only have one root directory avail on win xp pro. Knowledge database talks about utilizing multi headers, but I dont understand how its suppose to work with one IP and one port. Any help would be great. What about creating virtual directory, would that help

- Frontpage Client >> Publishing ProcedureHello.
You create a new site using FrontPage. You publish it to a server with
FrontPage extensions already installed. No problem!
Now you Frontpage website is 350-400 htm pages! You publish and FrontPage
takes forever to compare the local and remote webs in order to start
publishing!
Is that the only thing to do when publishing lareg websites through
FrontPage? ie, wait until the comparison process ends for FP to start
publishing the modified or new htm documents and pictures (if any)?
Please advise.

Probably not. There seems to be a number of problems getting this to work
remotely.
You might, however, be interested in this:

Thanks Eric, that code was just what I was looking for. Now if I can only get
it to work on my hosted site (works locally but I get "That assembly does not
allow partially trusted callers" when trying to run Atlas (ajax) on the
hosted server).

- ASP.Net >> "Thread was being aborted" exception on redirect - VERY weird!!Hello,
I have a page that is supposed to do some checking, and if OK, set a
session variable before redirecting to another page. The following code
is a simplified version, I have hard-coded the basket ID and removed a
load of extra checking...
public partial class GoToCheckout : Page {
public void Page_Load(Object o, EventArgs e) {
try {
Session["basketid"] = "178";
//x.Text = "redirecting to PreCheckout.aspx";
Response.Redirect("PreCheckout.aspx");
} catch (Exception ex) {
Response.Redirect("/?msg=" + ex.Message);
//x.Text = "exception - " + ex.Message;
}
}
}
When this page is called, it throws a "Thread was being aborted"
exception when it hits the line...
Response.Redirect("PreCheckout.aspx");
The catch block picks it up and redirects to the home page, putting the
exception message in the querystring. I did this because if I comment
out the redirect in the catch and instead use the (commented out) x.Text
bit (x is a literal, put on the otherwise empty .aspx file for
debugging), then the redirect works fine!!
If I comment out the redirect in the try block and uncomment the x.Text
line there, then the page displays the message "redirecting to
PreCheckout.aspx" exactly as expected.
So, it seems there's some weird problem with the redirect, but I can't
work it out. Nor can I work out why changing the behaviour of the code
in the catch block changes whether the exception is raised or not.
This code has been working fine for a few months now. I have recently
been changing pages to use master pages and themes, which is when I
noticed the problem. However, if I now change this page back to not use
a master or theme, the problem is still there. I am totally baffled, and
would appreciate any help you can offer. TIA

- ASP.Net >> Website security without javascript or cookiesWhat are the pitfalls of passing a token in the url once a user is
logged on so I can remember who they are?
I can easily implement this by adding &token=abcdefghijklmnop123 to
each internal link on my web pages once the user is logged on.
I won't be passing the username or password in the url, just a token
that is created when a user logs on. When the server receives the token
it maps it back to the account id. This saves the user from logging on
all the time and also means I don't rely on javascript or cookies.
I can make the token time out after ten minutes of inactivity. I could
also encrypt the client ip address in the token for further security
and check it on the server. Is this wise? How dynamic can IP addresses
be? Can a surfer's ip address change without dialing off and back in to
the isp?
My "token in the url" proposal isn't used by Amazon and that makes me
think I'm missing some security issue. Amazonseem to use cookies for
all but the secure pages and then seem to use a token in the url over a
https link for the more secure pages, which scrambles the token.
Thanks for any insights

- ASP.Net >> redirecting a form's POST targetnot sure if that subject makes sense ;0)
I've been asked to do something I've never had to do; Create a form and
"hide" the url that it posts to. They don't want a user to be able to view
the source and see the REAL url that the form is posting to, they don't mind
if the user see "a" url, just not the actual one.
For example:
The site's URL is www.someForm.com and the form needs to post it's data to
www.someFormDatabase.com
I want to post the form to www.someForm.com then on the server side
"re-post" it to www.someFormDatabase.com
I hope you are following me, if so, does anyone have any idea how to do
this? I'm sure it's possible, I've just never needed to do it before. Any
suggestions or help very much appreciated.
Thanks for reading,

- ASP.Net >> DropDownList Selecting itemUsing Visual Studio.net 2003 to create an aspx web form I am having a
problem selecting an item from DropDownListBox with id= ListBoxStudies.
I can see the items from the bound database table but when I click on an item
the selected item stays at itemindex 0. What must I do to have the
itemindex change when I click on an item. What's missing from the following
code?
ListBoxStudies.DataSource = BICDataSet.Tables("protocols")
ListBoxStudies.DataTextField = "Study_name"
ListBoxStudies.DataValueField = "irb_number"
ListBoxStudies.DataBind()
I have tested this using a submit button and the _SelectedIndexchanged event
and I still always get selectedindex = 0.
Private Sub DropDownListStudies_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Dim study_name As String = Session("study_name")
study_name = ListboxStudies.SelectedItem.Text
End Sub

This left-hand navigation is included on every single page in the site and
