return ( unescape ( results[2] ) );
else
return null;

Clearing Recent Projects list in Visual Studio 2005

If you had a list of projects listed on the Visual Studio 2005 Home page's Recent Projects section and wanted to clear any of these items, there is not a way to do it using the IDE.

You will need to go to the registry (Start->Run->regedit) and
remove entries from:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\ProjectMRUList

ASP.NET 2.0 GridView control in Paging and Sorting

ASP.NET 2.0 GridView control in Paging and Sorting
This article will describe how you can manually implement paging and sorting for the new GridView control in ASP.NET 2.0

First of all I set the AlowPaging and AllowSorting properties to true, then specified page PageSize attribute of GridView to 10. For each bound Column (that I want to be sorted) I specified the SortExpression attribute same as the column name in the database table.

After doing these initial changes you need to handle the Sorting event. There are two events for sorting one is Sorting and the other is Sorted. Sorted is called just after the GridView is sorted and it’s the Sorting event in which you will need to handle the sorting logic.

Here a GridViewSortEventArgs is provided from which you can get the column’s SortExpression and SortDirection. You will need to re fetch the data from database and bind that to the GridView and you need to restructure the query with order by and DESC or ASC clauses.

For Paging there is the event PageIndexChanging that gives the index of the new page clicked. Here you just need to set the PageIndex property of the GridView to the new Index and re bind the data to GridView.

Design Page :

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="GridViewTest.aspx.cs" Inherits="GridViewTest" %>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Grid View Sorting</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" OnPageIndexChanging="GridView1_PageIndexChanging"
OnSorting="GridView1_Sorting" AutoGenerateColumns="False">
<Columns>
<asp:BoundField DataField="ProjectID" HeaderText="ProjectID" SortExpression="ProjectID" />
<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
<asp:BoundField DataField="ShortName" HeaderText="ShortName" SortExpression="ShortName" />
<asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" />
<asp:BoundField DataField="EstimatedStartDate" HeaderText="EstimatedStartDate" SortExpression="EstimatedStartDate"/>
</Columns>

Relation objects in a dataset

How to use relation objects in a dataset?
DataSet's that contain multiple DataTable objects can use DataRelation objects to relate one table to another. Adding a DataRelation to a DataSet adds by default a UniqueConstraint to the parent table and a ForeignKeyConstraint to the child table.
The code sample below creates a DataRelation using two DataTable objects in a DataSet. Each DataTable contains a column named CustID which serves as a "relation" between two the DataTable objects. The example adds a single DataRelation to the Relations collection of the DataSet. The first argument in the sample specifies the name of the DataRelation being created. The second argument sets the parent DataColumn and the third argument sets the child DataColumn.

custDS.Relations.Add("CustOrders",custDS.Tables["Customers"].Columns["CustID"],custDS.Tables["Orders"].Columns["CustID"]);
OR
private void CreateRelation()
{
DataColumn parentCol;DataColumn childCol;
parentCol = DataSet1.Tables["Customers"].Columns["CustID"];
childCol = DataSet1.Tables["Orders"].Columns["CustID"];
DataRelation relCustOrder;
relCustOrder = new DataRelation("CustomersOrders", parentCol, childCol);
DataSet1.Relations.Add(relCustOrder);
