I have two applications configured in IIS. I need to Pass some values from one application to other using HttpContext object.
I have tried out using
FormsAuthentication.SetAuthCookie("Hello", false)
which sets one value in the Httpcontext object which i m retrieving from other application through
HttpContext.Current.User.Identity.Name property.
Upto this all works fine but i need to pass more user data using Httpcontext object and retrive it in other application.
How can i do that?
Is it possible to pass more user data Using HttpConext Object or not....
Please help me out

Actually, what is happening is simply a cookie being set on the client. SetAuthCookie establishes the user authentication cookie, which allows HttpContext.Current.User to be available.
If you want to application #2 to read application #1 data, you could have app#1 set a cookie that app#2 can then read.

I need to fetch the list of open windows, which all currently open in client machine. Though i did some finding and code is working in local web server, however this does not works if this hosted in remote machine.
I am trying to access the link (application hosted in remote server) in my local machine, and while doing so this does not return me list for currently opened windows.
What should i do to make this work? Here is the code sample i am using:-

}

mTitlesList.Add(title);
return true;
}

Yup that will happen because of the Asp.net nature.If you want this in client machine you have only one option that is ActiveX control...

Thanks. Let me do some more digging

As the code runs on the server it is returning you the open windows on the server, not the client PC. This distinction about where code runs is often overlooked but it is fundamental to understanding ASP.net. As the above post, you'd need ActiveX.

Why cant you try this. Simple when you are using only few parameters.
and dont forget to add where clause while updating, It may update all records in the table.
string str = "UPDATE ManageAboutJA SET Description='" + TextBox2.Text + "'";
SqlCommand cmd = new SqlCommand(str,conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();

This can cause SQL Injection.

you got what i have done...?

Good Mornig Malik1122
We cant know what is the Problem until we see the code, another thing that can be easly done on the SQL.
e.g
INSERT INTO TABLE2
SELECT COL1,COL2 FROM TABLE1
WHERE COL1 IS NOT NULL
Always try to keep the sql side in SQl , because these things can be achieve at ease that side than trying to loop through a datatable.
Please explain clearly what is your problem.

The column of 'tbl' are
1. FIRST NAME
2. LAST NAME
3. DATE OF BIRTH
4. AGE
5. GENDER
And that of 'tblSwapedColumns' are
1. GENDER
2. DATE OF BIRTH
3. AGE
4. LAST NAME
5. FIRST NAME

The Problem might be the names of your Columns in SQl it would be fine. Try not to name your Field names with Spaces , when Defining your Column names use something like th
First_Name or Firstname
Last_Name or LastName
please Fix that and try to run your code again

I'm not using any SQL Query to fill datatable. I'm just coying data from one datatable to an other datatable without the use of any Query.
