Yes sir you are right that "we should not block the back button of the browser using some javascript" because javascript can be disable for a browser.
As you suggested to check the session -- I am using Login control and form authentication, and after successfully logged in i have checked to count number of session available, but result found 0, because it keeps all information in a cookie. There is no any session. then how can i prevent to see the page before logged out.
If i manually set a session when user logged in and kill the session on logged out, then also someone can see pages (may contain confidential information) which was opened before logged out. Am I Right?
Then what is the proper solution to prevent see the confidential information opened during any one logged in??????
This Question was made too much earlier, So I think now u found the proper solution.
Please tell me sir.....
I am waiting for your reply...
Thank you in advance

I am not sure I got your question. But using sessions to keep login information is a standard practice. Sessions are stored in the server memory and unique for each users.

Do you mean when user presses back button? There are no efficient way to prevent the back button. You can do it using JS, which is not reliable. One solution I see is to open the users secured pages in a popup window, and close this window when user logs out.

There are good TWAIN SDKs available to purchase. I'm assuming you don't intend to handle scanning within Internet Explorer ? This is teh ASP.NET forum.

Do you mean 100 tables. ?  A dataset can contain tables. But not rows.
I assume that you have a datatable that contains 100 records and you want to take records between 5 to 10. So the code could be something like this
for(int i=5;i<=10;i++)
{
Response.Write(YourDs.Tables[TableName].Rows[i][YourColumnName].ToString());
}

Navaneeth. wrote: A dataset can contain tables. But not rows.
I think he want to say that Dataset contains 100 records means indirectly Dataset Contains one table which have 100 rows
so
!!! posted code is right 
Thanks and Regards

Hi,
I have been getting timeout errors for displaying my data. I used this code:
using System;
using System.Collections.Generic;
using System.Text;
namespace MyAdapters
{
public partial class working_step_a00TableAdapter
{
public string ConnectionString
{
get
{
return this.Connection.ConnectionString;
}
set
{
Connection.ConnectionString = value;
}
}
public void SetCommandTimeout(int timeout)
{
foreach (IDbCommand command in CommandCollection)
command.CommandTimeout = timeout;
}
}
}
And in the page load section, it has:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using MyAdapters;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
this.working_step_a00TableAdapter.SelectCommandTimeout = 300;
}
}
It doesn't understand 'using MyAdapters;' and it does not seem to work. What I am missing here? Thanks for your help.

Where is the class ?

Is SelectCommandTimeout static ? I don't see it there, at all.

I created the class as BLL/TechBLL.cs folder. Apparently, I am trying this out on the web and am getting session timeout. The CommandCollection seems to be only helpful for nonweb users. How can I get timeout session against the web? Thanks.

Hi all,
Been trying to play with Windows Sharepoint Services(2003 I think?) a bit recently and I'm having some pretty frustrating problems. My ASP.NET 2.0 knowledge isn't wonderful, but by my understanding, Web Parts can be used to wrap a user control and used in a web part page, correct? I tested a basic user control as a web part in my Vista environment using regular IIS and it seems to work fine. However, Sharepoint really doesn't play well with what I give it. I've looked at a bunch of different tutorials on how to get the things to work, but they just add to my confusion. Everytime I try to upload the Web Part I made to wrap a user control I did to Sharepoint, it tells me that I can't import the part. (Exact error message is: "Unable to add selected web part(s). Cannot import this Web Part.")
So does this mean that Sharepoint *requires* that you use the Sharepoint Web Parts framework/namespace, or can you use the regular ASP.NET ones found in the System namespace? And if I can use regular Web Parts, would the import error be from the configuration files? Thanks in advance for any assistance.

I have a dropdown control on an aspx page,with the first item
--Select a Customer-- Value -1
I used a compare validatore to compare the dropdown control selectedvalue with "-1",the validator did not fire
t.aransiola

Dropdown control on an aspx page:
--Select a Customer-- ----> Value -1
First ----> Value 1
Second ----> Value 2
Then set the following Properties for CompareValidator1:
1. Error message: U must select at least one value...
2. Test: *
3. Control to validate: ddlselect (Your Dropdown list name)
4. Operator : NotEqual
5. Type: Integer
6. Value to compare: -1
Now it will work. Try it out.

How can i send mail attachment to addresses that are stored in a database table.
e.g I have Customer Table with each customer address, i want to send email and attachment to all the customers
t.aransiola

Hmmm...tough question. Maybe retrieve the addresses from the database and send them each an email, or add them all to the to property.
only two letters away from being an asset

Hi all,
I know we're all mostly developers here, and not fairy designer types, but I'm in a bit of a fix since I'm on this web project all on my todd. So, does anyone know of a good place to get royalty free/public domain/ok to use in a commercial application XP Style Icons for the web? (I can probably stretch to $50.... the budget is real tight on this project!)
Cheers,
Martin.

It cost you $249. XP Style Icons[^] is it ok for you.
$50 and all hope you cannot get XPstyle icons i hope.

Hi,
I have dropdownlist named ddlapplication in my web form. When I click any item it insert
that record in database with primary key and show in gridview.
If user try to add the same record next time by clicking same item from the dropdown list
which already exist in database it should show error message that this
record alredy exist or in other words before inserting it should check wheather the record is already in database or not.
How can I do that. Here is my code
string str1 = this.ddlApplication.DataTextField;
string str2 = this.ddlApplication.SelectedValue;
string str3 = this.ddlPermission.SelectedItem.Value;
String constr = System.Configuration.ConfigurationManager.ConnectionStrings["twcsanConnectionString"].ConnectionString;
SqlConnection objConn = new SqlConnection(constr);
SqlCommand objCmd = new SqlCommand("INSERT INTO tbUsersAppRights(AppId, AppRightId, UserId) " +
"VALUES (@str1,@str2,@str3)", objConn);
objCmd.Parameters.AddWithValue("@str1", int.Parse(this.ddlApplication.SelectedValue));
objCmd.Parameters.AddWithValue("@str2", int.Parse(this.ddlPermission.SelectedValue));
objCmd.Parameters.AddWithValue("@str3", int.Parse(this.lblUserid11.Text));
objConn.Open();
objCmd.ExecuteNonQuery();
objConn.Close();
this.gdAddUser.DataBind();
seema

You will have to validate against the database, do a Select Count(Appid) From tbUsersAppRights Where AppID = @str1" and when count is zero you can insert the row into the database.
