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.

Thanks for reply.
but the problem is i am converting aspx page to pdf by using third party DLL. Here when i give an aspx URL it will execute that and create a PDF file, but it is not executing the link which is given to ImageURL of the image which resides on the aspx page. Please help me.
Thanks & Regards,

Your page should just contain the image, if you've done it right. No third party tool should change that, unless it flat out does not support images.

I have a page (supplier.aspx) which will dispaly the anual report of the suppplier on which i have to show the Logo of that supplier. Logo is in Database so first i have to get that to a page(Logo.aspx) i am doing so it is working properly on the aspx by writing the following line of code in the supplier.aspx.cs.
image.ImageURL="Logo.aspx?supid=4";
Upto supplier.aspx page it is ok it is displaying the logo but when i conert supplier.aspx page to PDF using
pdfConverter.SavePdfFromHtmlStringToFile(pdfData, "a.pdf");
here "pdfData" is html rendered code of the supplier.aspx page. Here is our problem when it converts into PDf it is not displaying the image because it can't execute the path which we had given to ImageURL. It is executing the physical path on the disk and getting the image to pdf from disk but it is not working with aspx page link. So i just want to put directly the image on to the supplier.aspx page without calling Logo.aspx page.
Thanks & Regards,

If you just want XHTML validation then check here:validate[^]

If you can't answer us, you want free tools, and you have no idea how to program, then I suggest you change careers, perhaps something in foodservice.

hello my friends. here is my questions
1)
i have made an application with a database.
i have made a win application with a database included. i wite the code using datasets,datatables etc... if i want to see the new datas in a table i have to reload the MyDatabase.mdf file in order to see them if i save datas when i run the application, so if i make a setup.exe for this app when i run it and do some sabes in the database will iu be able to see them in the app??
2)
i created an setup.exe
but when i fire tha icon to run it it says something about the database
"An attempt to attach an auto-named database for file C:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\WebSites\WebSite1\App_Data\aspnetdb.mdf failed. A database with the same name exists, or specified file cannot be Opened, or it is located on UNC share."
any suggestions???
thank you

1 - your mdf is your DB. I don't believe you can use it without SQL Server installed. Once it's there tho, it will work, obviously
2 - Looks like you created an installer with your aspnetdb database. You shouldn't need to do that.

The information in the table in the link is displayed from NSE(National Stock Exchange of India). Therefore find whether there is any web service is available to get the information. If there is any web service is found, then register for it, consume the web service and display the data in your web site. You can use ajax timer control to refresh it.
If you have any working RSS to get the stock data, then look into this link[^] which will help you display information from RSS feed.

I have a modalpopupextender inside the updatepanel
i want to focus the first control after i call
the Modalpopupextender1.show();

scriptmanager.GetCurrent(page).SetFocus("TextBox1");

scriptmanager.GetCurrent(this.page).SetFocus(TextBox1);

If TextBox1 is in a UserControl, then
TextBox txt1 = (TextBox)WebUserControl11.FindControl("TextBox1");
if (txt1 != null)
ScriptManager.GetCurrent(this).SetFocus(txt1);
|
|
|
|
|
still i am not getting the focus on textbox
Hi
my webusercontrol name is TxtMandatoryString
i wrote the code in .aspx.cs
button1_Click(Object sender,EventArgs e)
{
Modalpopupextender1.Show();
TextBox Tx=(TextBox)TxtMandatoryString.FindControl("Txt1");
if(Tx!=null)
{
ScriptManager.GetCurrent(this).SetFocus("Tx");
}
}
i run it in debug mode also
it goes inside the if loop
after that it goes to disassembly.cs finally the page is displayed without focus on the textbox(Txt1)...
