Working with DB2, from a .NET application developer's perspective, is just like working with any other relational database. One can find endless examples of how to perform databases tasks (from the mundane to the interesting) for Microsoft SQL Server and Oracle, but there is not as much similar documentation for accessing DB2 from Microsoft technologies, including .NET.

A C# property

public class SimpleProperty 
{
   private int number = 0;
   public int MyNumber 
   {
   get {  return number; }
   set {  number = value;}
   } 
}
public class UsesSimpleProperty
{
   public static void Main()
   {
      SimpleProperty example = new SimpleProperty();
      example.MyNumber = 5;
      int anumber = example.MyNumber;
   }
}

This has nice section on static initializers and static constructors

. Create a dummy xml
. use xsd.exe to create the .xsd file
. use Visual studio to tweak the XSD for a) cardinality and b) data types

Caveat: There may alternate ways to generate the complex types in the XSD than the default approach that XSD takes. Nevertheless it should work.

Idea of a web page control in .net

adding template columns

To set a combo box ( or list box ) to all of the values in an enum, do the following.

this.ComboBox1.DataSource 
   = Enum.GetNames( typeof ( YourEnum ));

Then to get it back out.

YourEnum val 
   = (YourEnum) Enum.Parse(typeof(YourEnum)
          ,comboBox1.SelectedItem.ToString());

Masterpages are keys in constructing websites in asp.net. They provide the background for a website such as the top banners, left hand navigation, footer etc. In this exercise you will need to

1. Create a basic empty website
2. create a main master page (banner, left hand menu, footer)
3. create a web page that will use that master page
4. Create a child/nested master page (provide a page menu on the right)
5. create a web page that uses the nested master

Anatomy of an asp.net web page

Introduction

For an experienced html web programmer it shoudl be really quick to start writing code in any framework as the concepts are similar. This article will give you a quick start to start developing web pages while highlighting the important elements with out fluff. This information is distilled from a number of web sources and also books.

Prerequisites

it is assumed that you are familiar with the general idea of asp.net where html controls are represented as server side control objects. The web page with an extension of .aspx will contain the placement and configuration of these control. The codebehind file contains the manipulating logic for these controls.

This exercise

The goal of this exercise is to display the output of a select statement in a data grid. Make one of the columns hyperlinked so that one can see the details in a separate web page. The deliverables are two aspx pages with their respective code behind files.

Some notes on .net exceptions

DataSet dataSet = new DataSet();
DataTable dataTable = new DataTable("table1");
dataTable.Columns.Add("col1", typeof(string));
dataSet.Tables.Add(dataTable);

string xmlData = "<XmlDS><table1><col1>Value1</col1></table1>";
xmlData += "<table1><col1>Value2</col1></table1></XmlDS>";

System.IO.StringReader xmlSR = new System.IO.StringReader(xmlData);

dataSet.ReadXml(xmlSR, XmlReadMode.IgnoreSchema);

Important for googling

http://www.microsoft.com/mind/0798/webbrowser.asp

A formal article. Quite old though. 1998.

When an internet explorer control is embedded in a power builder window, the internet explorer seem to loose session cookies for popups. Obviously this is not desirable for a reason. This drawback prevents from embedding fully functional web applications inside of a client server systems such as those built powerbuilder, delphi, or home grown.

While searching for the related material in google it might interest the reader to note the following key words in their order of narrowness/importance descending.
