Windows Forms Charting - Drawing Charts

C#Today

GDI+ is the latest version of Windows Graphic Device Interface, which is the part of Windows that abstracts commands like draw a window, draw a line, etc. into commands that our video driver can understand in order to display images on our computers screen. Weve already seen some of the advanced GDI+ features available to us in Matthew Reynolds' 'Irregular Shaped Forms and Other Cool GDI+ Features' article. In this article Matt looks at some of the more basic features and builds a simple user control that can draw a 3D bar chart. In Part 2, we continue the development of the chart, making it user-interactive.

Working with Complex Data Types in an XML Web Service - Part 1

ASP.NET provides three data controls for working with the output of a data store query, the DataGrid, DataList and Repeater. The DataGrid, in its most basic form, renders typical HTML table-grid output, the DataList renders on row and one cell per record, and the Repeater is the folding metal chair of data controls, which renders no specific output, and is fully customizable to render in the manner most appropriate for your application.

Working with Complex Data Types in an XML Web Service - Part 1

XML Web Services enable the exchange of complex data types, serialized as XML. Complex data types, such as ADO.NET DataSets and custom classes can be serialized as XML and either sent to the XML Web Service as an input argument, or returned from the XML Web Service as the result. In this article we will build the beginning of an XML Web Service, which we will finish in next week's article, when we will also build a consumer Web application.

Welcome to part two of Access Stored Procedures. Part one described in detail how to create stored procedures in Access using ADO.NET and Visual Basic.NET. Part two will demonstrate how to utilize the stored procedures created in part one by assembling a Database Tier that can be modelled and used in your own applications. This article will describe in detail one implementation of a Database Tier for Visual Basic.NET.

In this article, Salim Naim explores XML, and how we can work with it as an object model. He shows that XML is truly a core technology layer in .NET, while manipulating and working with XML documents with .NET is a natural method built into the .NET Framework, and not an after thought. He covers various techniques, including how to make use of the core functionality provided by the Base Class Libraries in the .NET Framework classes relevant to XML, and also looks at the two abstract base classed XMLReader and XMLWriter, which the XML classes are built upon.

There are quite a few examples floating around the Internet of how to perform tasks using XML documents. Theres just as many, if not more, that deal with solutions involving DataSets. However, one of the commonly neglected scenarios is writing code that not only uses a DataSet, but also utilizes an XML document to represent the same data. In this article Kevin Hoffman, firstly, gives you some background information on synchronizing DataSets and XML Documents via the XmlDataDocument class. He then explains how you can provide a relational view of a subset of an XML document, by adding an XML Schema into the equation. He then gives several fully functional examples using practical data and scenarios.

XML Features in ADO.NET

XML and some of its related technologies, including XPath, XSL Transformation, and XML Schema, are unquestionably at the foundation of ADO.NET. As a matter of fact, XML constitutes the key element for the greatly improved interoperability of the ADO.NET object model when compared to ADO. In ADO, XML was merely an (non-default) I/O format used to persist the content of a disconnected recordset. The participation of XML in the building and in the inter-workings of ADO.NET is much deeper.

XmlClient Managed Provider

This is my first attempt at writing a Managed Provider. The idea behind it was to allow users of the Managed Provider to be able to fill DataSets from XML in a homogeneous way. This way you could mix XML and database data together without having to know exactly which is from which.
