This is not a quite simple as I think.but may be this suggestion helps you
Follow these three steps
Store Procedure
First Step : Create temporary table
CREATE TABLE #TempTable
(
ID int IDENTITY PRIMARY KEY,
Column1 nvarchar(100),
Column2 nvarchar(100),
)
Second Setep: Insert matched records from other tables into temporary table
INSERT INTO #TempTable(column1,column2)
Select column1,column2 from myTable1 where column3=yourSearchingText
INSERT INTO #TempTable(column1,column2)
Select column1,column2 from myTable2 where column3=yourSearchingText
INSERT INTO #TempTable(column1,column2)
Select column1,column2 from myTable3 where column3=yourSearchingText
Third Step : Select all records from temp table
SELECT * FROM #TempTable
Best of luck

Or possibly just use a UNION predicate? Better asking this in the SQL forum...

Dear All
Is any one haveing have script wich converts english to french(in a text box)
Thanks

Oh god not again!
What makes you think Javascript alone would be capable of this task? Sure javascript could kick of an AJAX call to a server side translation engine... but thats not really javascript "converting english to french".
You dont seem to have much asp.net or web development experience? Try a beginners book on the subject and go from there. start smaller than a translation engine!

This is easy to write. You just need to send every English word and it's French translation to the client with every page. Your website will obvioulsy be huge and very slow, but you can do it, if you want to.

Why do you want to store password in session?
To store variable in session,
Session["MyKey"]=VariableName;

You can't.
Onclick of browser Back or previous button,Just history of browser is change and content of page get back from cache memory.Page is not reloaded so you can not run code.

If you put Session.Abandon(); in the page_load then that should do the trick. The only issue is that it will abandon the session everytime the user goes to that page.
Not a big deal if it's on the Login page though.
Hope this helps.

Session["UserId"]=txtuserid.text.trim();
To clear session
Session.Abandon();

I used the System.Diagnostics.Process.start method to open an application from an ASP.Net. It works fine when I debug it using VS 2005, but when I put it on a web server and click the button nothing happens. Please help me resolve this issue

Process runs on the server side so you can not see that process on client side.

Thank you for responding. Is there another method I can use instead of process?

I want to open an application written in vb.net using VS2005.

Just using asp.net you will not be able to open (or generally interact at all) with a client computer. You'll need some kind of ActiveX or Applet control for this.
