Just search it in CP Q&A forum. This has been asked number of times:

one of the ways: Try...In you logout event:

protected void LogOut()   
{       
     Session.Abandon();       
     string nextpage = "Logoutt.aspx";       
     Response.Write("<script language=javascript>");             
     Response.Write("{");       
     Response.Write(" var Backlen=history.length;");       
     Response.Write(" history.go(-Backlen);");       
     Response.Write(" window.location.href='" + nextpage + "'; ");
     Response.Write("}");       
     Response.Write("</script>");   
}

This particular question has been asked so many times. I am not able to provide you the codeproject search link for search "disable back".
You may try searching. You would get a lot of hits.
You may also search Google for "disable back button" if that does not satisfies you.
Here are few links from codeproject:

http://www.codeproject.com/Questions/73968/Disable-back-option-after-logout.aspx[^]
http://www.codeproject.com/Questions/53733/how-to-disable-browser-back-button.aspx[^]

Hope this helps!

The best option is
(1) check for a valid session object as the first statement to be executed for your page load event handler. If there is no session (or session object is null you write code to redirect user to login and force user to create a session. Assumption is, while logging out code is written to clear Session which has been created at the time of "Login".
(2) Sometime, developer creates "Base" page class and write this kind of session checking in base page itself so that every derived page class follows the same.

This way, you can set aside any dependency of javascript.

Hope it helps you,

Thanks,

You should go here: Google: Did web service come first or Dotnet?[^]

BTW: a simple thought (based on what they are) would had told you that .NET is a new technology and Webservices (a way to communicate) are from before!

Hello.

Im having few textboxs,image button and Button in a page.
default button is set to button control and focus is on one of the textboxs but when i press enter after page loads the control shifts to image button. Why does this happen?

Sandeep Mewara1-Jun-10 19:43

1-Jun-10 19:43

Are all the controls in the same panel of the page and panel has a defined default button?
If not, try that.

m@dhu1-Jun-10 20:54

1-Jun-10 20:54

All controls are in same panel

Sandeep Mewara1-Jun-10 21:22

1-Jun-10 21:22

Ok. So after page load where is the focus? on button or image-button?

If default button of panel set to button, once page loads, enter should trigger simple button click. Are you doing something different?

Dear friend,
I am trying to fetch data from excel sheet using ASP.NET with C#. I want to get data based on one date condition. All the rows in that date column are having date only. I don't know what's wrong. I have tried in many ways. I am getting the following error.

[System.Data.OleDb.OleDbException] = {"Data type mismatch in criteria expression."}
Since last day afternoon, I am struggling for this. I have written queries in all following possible ways.

select * from [sheet1$] where [LoginDate]='21/04/10'
select * from [sheet1$] where [LoginDate]='21/04/2010'
select * from [sheet1$] where [LoginDate]='21-04-10'
select * from [sheet1$] where [LoginDate]='21-04-2010'
select * from [sheet1$] where [LoginDate]='21-Apr-10'
select * from [sheet1$] where [LoginDate]='21-Apr-2010'
select * from [sheet1$] where [LoginDate]='04/21/10'
select * from [sheet1$] where [LoginDate]='04/21/2010'
select * from [sheet1$] where [LoginDate]='04-21-10'
select * from [sheet1$] where [LoginDate]='04-21-2010'
select * from [sheet1$] where [LoginDate]='Apr-21-10'
select * from [sheet1$] where [LoginDate]='Apr-21-2010'
select * from [Sheet1$] where [LoginDate] = '"+DateTime.Parse("04-21-10").ToString()+"'"
select * from [Sheet1$] where [LoginDate] = '"+DateTime.Parse("04-21-10")+"'"

Still I am not getting. Can anyone, pls help me. It's very urgent.

Regards,
Dileep

There is a known issue with OleDb and dates!
It expects dates in format: "yyyy-MM-dd hh:mm:ss"

Try something like:

"SELECT * FROM [sheet1$] where [LoginDate]='" + myLoginDate.ToString("yyyy-MM-dd hh:mm:ss") + "'"

Read this thread for details and one more other option to use parameters: Data type mismatch in criteria expression[^]

Thanks friends,
I have got it in another way.

select * from [sheet1$] where LoginDate=#21/04/10#

It's working fine.

Thanks everyone.
