I want that value of textbox to be converted into base64 string so that i can sent it to another page as encrypted username from response.redirect....what i used
<code>Convert.FromBase64String(textbox1.Text);</code>
how to save this converted value and in what data type...and i want it converted into string so that i can send encrypted code to another page and then decrypt it and again save it as string.....please suggest any easy way.....

Use this Code below
string str = textbox1.Text;
string encstr = Convert.ToBase64String(System.Text.Encoding.Unicode.GetBytes(str));
string decstr = System.Text.Encoding.Unicode.GetString(Convert.FromBase64String(encstr));
encstr represents the base64 encrypted string which you can pass between pages, and decstr is the string decryption. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

THNX!!!! alot  i got my problem solved...but please could you explain it....i can't understand the use of ascii encoding then base64 string use....

Well,
Convert.ToBase64String takes a byte array. You need to convert your string to Byte array. You can do it using a for loop and create the Byte array yourself. System.Text.Encoding.Unicode.GetBytes does it for you. 
On the contrary, the reverse is Convert.FromBase64String returns a byte[], so again you need to convert Byte array into string. System.Text.Encoding.Unicode.GetString does it for you .. .
Hope this help you.

it is known that some text size in the webpages will be changed by changing textsize in the view menu in the internet explore setting.
I want to know is it possible to fix the text size (e.g. label), which is not changed by the textsize setting in the explore?
if so, and how?
thanks.

Why would you want to do this? The point of having the option to change font sizes in the browser is to allow the user a choice. It isn't a good design to take that choice away. Instead you should make your layout flexible enough the handle the change.

this may be so called Ajax application in ASP.net.

Nopes dear..
AJAX is Asynchronous Javascript and XML. Well, AJAX relates to XMLHttpRequest Object present in Javascript API which can call to the server. Just like you postback to get data from the server, if you dont want to postback but call the server from your client using Javascript, you can use XMLHttpObject. To get more knowledge about AJAX try AJAX W3Schools [^] tutorial.
This is simple JavaScript fix in the client side.

How does it related with ASP.NET ? If you have to ask it on General DB Forum.

Why you want to avoid Wizard ? Do you want to do it programmatically.?

Connect to master Database using your .NET object. Then run the stored procedure below :
EXEC sp_attach_db @dbname = 'dbname',
@filename1 = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\dbname.mdf',
@filename2 = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\dbname_log.LDF'
Please replace the path to the existing mdf and ldf files.
You can also create using
CREATE DATABASE [dbname] ON
( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\dbname.mdf' ),
( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\dbname_log.LDF' )
FOR ATTACH
GO
command
Hope you can do this now.

Am currently working on my end of semester project (online examination system )where questions are to be obtained from a database,cached on a dataset and store the dataset in session object(of the global asax file).questions are read from this session variable and displayed on a form on its form load event.this form has 3 buttons that can enable a user to navigate to the next question,previuos question(s) and another to intentionally end the exam.whenever a user clicks on the back button of the form to access a previously answered question,the previous question is shown but the radio button that was checked as the answer is not checked.Any idea on how can i maintain the checked status for the previously answered questions?

So you don't record and persist the answers they provided to the questions?

First of all, dont do this. Why do you have to set an Entire detaset in session, rather you store in database and get when required.
mbams wrote: whenever a user clicks on the back button of the form to access a previously answered question
Well, in your case, as I said, always store user's input to the database. Use <a href=nextpage.aspx> to ensure everything to be in the history. If you really require the back functionality you should use <a > tag.
Hope you are getting me.

Use
OracleClient classes.
System.Data.OracleClient Namespace allows you to connect to Oracle Database.
|

I am not able to use this namespace. For connecting to Oracle should i have any add on or any assembly?
