Deleting Cookies

Deleting a cookie—physically removing it from the user's hard disk—is a variation on modifying it. You cannot directly remove a cookie because the cookie is on the user's computer. However, you can have the browser delete the cookie for you. The technique is to create a new cookie with the same name as the cookie to be deleted, but to set the cookie's expiration to a date earlier than today. When the browser checks the cookie's expiration, the browser will discard the now-outdated cookie. The following code example shows one way to delete all the cookies available to the application:

Visual Basic
Dim aCookie As HttpCookie
Dim i As Integer
Dim cookieName As String
Dim limit As Integer = Request.Cookies.Count - 1
For i = 0 To limit
cookieName = Request.Cookies(i).Name
aCookie = New HttpCookie(cookieName)
aCookie.Expires = DateTime.Now.AddDays(-1)
Response.Cookies.Add(aCookie)
Next

C#
HttpCookie aCookie;
string cookieName;
int limit = Request.Cookies.Count;
for (int i=0; i{
cookieName = Request.Cookies[i].Name;
aCookie = new HttpCookie(cookieName);
aCookie.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Add(aCookie);
}

Exact Displayed Url in the browser

Request.RawUrl gives you the exact url in the address field of the browser.
This is important when you use url rewriting.

if the above step doesnt help you, please try the below:
Request.ServerVariables("HTTP_X_REWRITE_URL")
This will definutely help you out when using rewriting tools like helicon or so.

If anybody still doesnt get the exact url in any scenario, please let me know, so that i can also help you through... I challenge this !!!

Crystal Report Configuration Isuses in Vs.net 2008

I migrated one web application done in 2.0 to 3.5 framework. It worked fine after migration. So at the time of migration i had both VS.net 2005 and VS.net 2008 intsalled on my machine. Then i removed VS.net 2005 as i dont needed it anymore.

Then while building the solution, i got the following error:
the assembly 'CrystalDecisions.shared/Web/Engine, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' could not be loaded

Finally i managed to fix it by doing the following things:

1) Install the crystal runtime package that can be found on your local computer (I believe it is installed with visual studio 2008). It is located in:

\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\CrystalReports10_5

Select the appropriate package for your machine.

2) Modify web.config with all crystalreport assemblies so that it will be of new version eg:



3) Build solution. Now the solution successfully builds up !!!
