While I agree that server names are better, I have had just as much trouble with Network guys F* up the DNS requiring the use of IP Addresses instead as the more reliable solution. There has been a noticeable increase in lazy sys-admins.

as u said,i given the server name instead of ipaddress
like this
con = New SqlConnection("Network Library =DBMSSOCN; server =server1ABN; database = dvk; user id = sa; password ="";timeout = 60")
but i get this error
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - No such host is known.)
all configurations are enabled to Sqlserver.
only a ipadress of the server is changed.
if ipadress of the server is changed then do we have to reconfigure the sqlserver with new ipadress
from the past 1 week the website is running properly
now the same server is configured with a new ipaddress
This problem occurred with the changing of ipaddress
can u help me

Is it the same server or are you pointing to a new server? If it is a new server make sure it is configured to accept TCP connections and not just named pipes if you are going to specify the network library. Are you sure there are no firewalls in between your web server and SQL server that could be restricting traffic on port 1433?
Oh and by the way NEVER EVER EVER EVER use the sa account.

I don't understand what you are trying to do but if you just require to achieve this, then follow these steps:
Add a Table to the new DataSet.
Add Columns to the Table.
Assign these columns to the corresponding columns. Something like
NewDataSetObject.Tables[0].Columns[0] = DataSet1.Tables[0].Columns[0];
I would rather recommend you to explain your scenario and answer these questions:
Where are these data coming from? Why have you taken one DataSet for 1 Table?
Why are you creating another DataSet when you can assign a DataSet, containing these Tables, as a DataSource ?
..Go Green..

Write a class that implements IComparer.
public class myComparer : IComparer
{
public Boolean Descending;
#region IComparer Members
public int Compare(object x, object y)
{
Double obj1 = (Double)x;
if (obj1 < 0) obj1 = -(obj1);
Double obj2 = (Double)y;
if (obj2 < 0) obj2 = -(obj2);
if (Descending )
{
if (obj1 < obj2 )
return 1;
if (obj1 > obj2)
return -1;
}
else
{
if (obj1 > obj2 )
return 1;
if (obj1< obj2)
return -1;
}
return 0;
}
#endregion
}
Pass a object of your custom class in ArrayList.sort method
ArrayList arr = new ArrayList();
arr.Add(0.3);
arr.Add(0.2);
arr.Add(-0.3);
myComparer objComparer = new myComparer();
objComparer.Descending = true;
arr.Sort(objComparer);

you can do some thing like this
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
List<decimal> lstIntCol = new List<decimal>();
lstIntCol.Add(0.3M);
lstIntCol.Add(0.2M);
lstIntCol.Add(-0.3M);
lstIntCol.Sort(new decimalComparer());
foreach (decimal d in lstIntCol)
{
Response.Write(d.ToString() + "--");
}
}
}
public class decimalComparer : System.Collections.Generic.IComparer<decimal>
{
#region IComparer<decimal> Members
public int Compare(decimal x, decimal y)
{
return decimal.Compare(Math.Abs(y),Math.Abs(x));
}
#endregion
}

I use an access db with my website(.mdb file). I try to run 3 standard sql INSERT, DELETE and UPDATE statements. When I run the website locally on my computer it works great with no problems, but when I upload the website to the server and try to run the SQL statements I get 2 exceptions:
for the Insert statement:
System.Data.OleDb.OleDbException: Operation must use an updateable query.
for the Update statement:
Invalid SQL statement; expected 'DELETE', 'INSERT', 'PROCEDURE', 'SELECT', or 'UPDATE'.
for the DELETE statement:
System.Data.OleDb.OleDbException: Could not delete from specified tables.
I have to mention that the rest of the site works well with no special problems, including the pages where I read from the db tables by executing sql SELECT statements

It's seems you are having problem with the Writable operation as your "Read" operation working properly and "Insert", "Update", "Delete" is not working.
Please make sure that, In Web Server, you are having (In which credentials your application is running ) proper rights to write access on DB Server.
Hope this will helps !!

this is my code regarding above code
namespace TestProject.ViewModels

public List<string> _genres;
public int Numberofgenre
{
set { _numberofgenre = value;}

}
public List<string> Genre
{
set { _genres = value; }

Correct in what sense? If it compiles, it is syntactically correct. You can check that yourself. If it does what you want it to do, it is logically correct, may not be the best/optimum logic though.
I think you should describe what do you mean by correct.
Anyways, here are a few things that you may consider:
1. If you are using .Net 3.0 or above, make use of automatic properties.
2. You can make use of XML comments and regions in stead of commenting using "//".
3. You can make your fields private and have them only when it is really needed.
4. No need of having "this" keyword unless really needed.
5. Make use of Generic lists or Collection since they are strongly typed.

Your field definition need to be private. You have public accessors.
|
|
|
|

In addition to the other comments you should use the properties rather than access the fields directly
this._numberofgenre = numberofgenre;
Should be
Numberofgenree = numberofgenre;
This way any logic that needs to be executed when a property is accessed will not be by-passed. Also, if the backing field changes it will not affect the code.
Most coding standards also dictate the use of Pascal casing for properties and methods
Numberofgenre => NumberOfGenre
Many also prefer fields to begin with m_
public int _numberofgenre; => public int m_NumberofGenre;

Hi,
I am just trying to learn JQuery.
I want to try out a basic JQuery example. Adding items from one list box to another.
It works fine in the normal aspx page (I pasted it in Default.aspx in root directory).
I placed JQuery Libraries in a folder Javascript under root.
This works fine.
Then I created a WebUserControl and placed the same code and I registerd this user control in default.aspx.
The page loads , but when I click on Add it does not move items from one list to another.
While in the aspx page, I checked the Watch and
innerHTML of the context->childNodes has values "Delhi, Bombai ..........". Same as OuterHTML.
But in the user control with the same code as pasted below.
innerHTML is "" and OuterHTML is "<HTML4F>"
Please throw some light to this
See the code below:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="User_Controls_WebUserControl" %>
<script src="../Javascript/jquery-1.4.1.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
$(document).ready(function () {
debugger;
$("#add").click(function () {
debugger;
$("#fromListBox option:selected").appendTo("#toListBox");
});
$("#addAll").click(function () {
$("#fromListBox option").appendTo("#toListBox");
});
$("#remove").click(function () {
$("#toListBox option:selected").appendTo("#fromListBox");
});
$("#removeAll").click(function () {
$("#toListBox option").appendTo("#fromListBox");
});
});
</script>
<table>
<tr>
<td><asp:ListBox ID="fromListBox" runat="server" SelectionMode="Multiple" Rows="6">
<asp:ListItem>Delhi</asp:ListItem>
<asp:ListItem>Chennai</asp:ListItem>
<asp:ListItem>Pune</asp:ListItem>
<asp:ListItem>Kolkata</asp:ListItem>
<asp:ListItem>Mumbai</asp:ListItem>
<asp:ListItem>Bangalore</asp:ListItem>
</asp:ListBox></td>
<td> <input id="add" type="button" value="Add" /><br/>
<input id="addAll" type="button" value="Add All" /><br/>
<input id="remove" type="button" value="Remove" /><br/>
<input id="removeAll"type="button" value="Remove All" /><br/></td>
<td><asp:ListBox ID="toListBox" runat="server" SelectionMode="Multiple" Rows="6"></asp:ListBox> </td>
</tr>
</table>
