Say I have many control buttons in the ASP.NET developped web page, each upon being clicked will do some operatoin which may take some time, when the button is clicked, a progress bar(in my case, I used an animated gif) will be shown while keeping the web page being freezed (by word "freeze", I mean the web page will be made inactive when the progress bar is being displayed in the center of the window, the user can still see the web page, however, he cannot click on any controls in the web page, the web page will be active again until the operation completes and the progress bar disappear.)
Can anybody suggest how I may do the web page freezing?

You put a transparent div over the entire page.

Just create one div, set the opacity of it to 60, make position : absolute, set top and left, z-index anything greater... and you are done.
There is also a bug in IE 6 where select controls comes over the div, use Iframe to hide them as well.

Your problem is that you don't have a clue. Why would any of this code open the link on a new page ? Seriously. Buy a book on HTML and read it, or just try using google.
You may try here[^] for the answer. Or perhaps here[^].

hi,
Actually I want to create page with resolution(size) 1024*768.
Now my pc's resolution is 1440*900.
So whenever I execute prog, in 1440*900 resolution, the website will display in centre keeping some place left and right side.
and whenever I use 1024*768 resolution, it will cover whole screen, not keeping space left or right. It will be fit to screen.
How can I get this ??
I have tried a lot but I can't get this.
Plzz help me..
Thanks & regards,
Jay

Hi Jaymm,
Setting the Width and Height in Pixels make the page dependent on resolution. If you will set the Width and Height in 100% it will not be dependent on resolution and What ever resolution you will set the page will fit on to that resolution only. Set as below
Width="100%", Height="100%"
Hope this help.
Thanks,

hai all,
i am using the below function for password encryption.here my password is changing into encrypted form,but i dont know how to check that encrypted form password with plain text password from database?
because database contains plain text password.Please can anybody respond my question.
i wanted to use md5 in my login page.
I dont know exactly how to use it.
Public Function MD5Encryption(ByVal passwd As String) As Byte
Dim i As Integer
Dim md5 As MD5CryptoServiceProvider = New MD5CryptoServiceProvider
Dim hashedbytes As Byte()
Dim textencoder As UTF8Encoding = New UTF8Encoding
hashedbytes = md5.ComputeHash(textencoder.GetBytes(passwd))
md5.ComputeHash(textencoder.GetBytes(passwd))
Dim right As StringBuilder = New StringBuilder
For i = 0 To hashedbytes.Length - 1 Step 1
right.Append(hashedbytes(i).ToString("x2"))
Next i
If (right.ToString() <> passwd) Then
Response.Redirect("login.aspx")
md5.Clear()
Else
Response.Redirect("index.html")
End If
End Function

thanks for ur reply.exactly u r correct.If stored the password in encrypted form in the database can anybody know whats the password is?
if some use asking his forgotten password,then how can i tell immediately if i look at the databse.
For security purpose i wanted to encrypt,but the concept of storing encrypted password in the databse may lead to some other problem?
Pleas understand my question and answer me.
Thans once again

You have some major issues.
1 - MD5 is a hash, NOT an encryption. Therefore, you have to apply MD5 to your entered password and see if the hashes match.
2 - MD5 is not very secure at all. It's better than plaintext, but not much good against a serious attacker. Your best bet is to add some salt, and hope they can't work out what that is

The concept of storing your non encrypted password leads to the problem you're trying to avoid. No two ways about it. Try thinking this through, just a little.

How important is it that these passwords remain protected?
Just remember that if somebody has access to your passwords within your database then they probably have access to all your other data too which makes it kinda pointless encrypting all your passwords.

thanks once again
yes u r correct,
1)but the use may change his password in later.At that time is that sqlserver automatically convert the changed password into encrypt form.
2)No this time how do i know what user has changed?
This is my question,i have no idea please guide me through ur knowedge.
So please tell me the answer

hi..i m facing most of the same problem as u. my problem is that, i've taken any random number and encrypt it through md5 and store it in the database.. but while changing password, when i want to check that random number with that encrypted password(i've encrypted the random number) then the encryption of the random number is not same as that one which is stored in database. while checking, i m giving the random number through text box. i think(with my a bit knowledge), encryption of value of a variable will not be same as encryption of the same value entered by the textbox. it can be some database problem also....i dont know.... i m sure that my coding is correct

Hi,
I have written a linq query and bind it to a gridview. Now i want to implement sorting on gridview columns for which i want this linq query to store in dataview.
So how it is possible to store linq query in dataview.
the following is the code which i have written to bind gridview.
protected void BindGrid()
{
try
{
var employees = from e in DetailContext.Employees orderby
e.Emp_Code descending
select new {e.Emp_Id,e.Emp_Code,e.F_Name,e.L_Name,e.Designation };
GridView1.DataSource = employees;
GridView1.DataBind();
}
catch (Exception ex)
{
throw ex;
}
}

There is one .cs for converting linq to datatable
//.cs file
using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using System.Data;
public class LinqToDataTable
{
public static DataTable ObtainDataTableFromIEnumerable(System.Collections.IEnumerable ien)
{
DataTable dt = new DataTable();
try
{
foreach (object obj in ien)
{
Type t = obj.GetType();
PropertyInfo[] pis = t.GetProperties();
if (dt.Columns.Count == 0)
{
foreach (PropertyInfo pi in pis)
{
if (pi.PropertyType.Name == "Nullable`1")
{
string str = pi.PropertyType.FullName;
str = str.Replace("System.Nullable`1", "");
str = str.Substring(str.IndexOf("System"));
str = str.Substring(0, str.IndexOf(","));
dt.Columns.Add(pi.Name, str.GetType());
}
else
dt.Columns.Add(pi.Name, pi.PropertyType);
}
}
DataRow dr = dt.NewRow();
foreach (PropertyInfo pi in pis)
{
object value = pi.GetValue(obj, null);
dr[pi.Name] = value;
}
dt.Rows.Add(dr);
}
}
catch (Exception)
{
dt = null;
}
return dt;
}
}
//DataTable dtEmployees = LinqToDataTable.ObtainDataTableFromIEnumerable((IEnumerable)employees);
now assign the datatable in dataview

Is there a way to convert an System.Drawing.Image to an System.Web.UI.WebControls.Image?
Im getting the image from database, the binary being in base 64 string. I then convert it back to an array of bytes. My problem is that I can't find a way to create the System.Web.UI.WebControls.Image with a Stream or an array of bytes... I got the Image from Drawing but I can't convert it back to a WebControl Image.
I suppose I must write down the file somewhere on the server then return the path but I dont want to leave these temporary images on the drive.
Any ideas or suggestion anyone?
Thanks & Regards,
Anil Chelasani

No. The namespace is the clue. One is an image, and one is a control that shows an image. You need to write a page that returns the stream of bytes, and point an Image control to it.
