I'm proud to announce the release of the next version of MVC# Framework. New features include:

  • Support for Silverlight 2.0 (beta 2) platform.
  • Examples supplemented with Silverlight presentation.
  • Improved support for Windows Forms, fixed some bugs.

In WinForms controls' overlapping (z-order, in other words) is adjusted easily by calling Control.BringToFront() and Control.SendToBack() methods. In Silverlight 2.0 the way to change z-order is not as straightforward although quite simple too.

First of all the default overlapping is controlled by the order in which controls appear in XAML: each subsequent element is placed on the top of the previous ones, like in the example below:

 

For changing the z-order in the XAML markup the Canvas.ZIndex attached property should be applied to elements. Higher property values place the control on the top of others: 

The same effect can be achieved through the C# code by using Canvas.S ... Read More »

API documentation may be of great importance to a project. Especially when the project is a library intended for use by other developers. As a rule such documentation is represented in a form of help files (*.hxk for instance) or in a form of HTML pages contating reference for all project's namespaces, classes and etc.

However neither .NET framework nor Visual Studio contain tools for creating API documentation. Instead, developers need to address some separate tools for this aim.

For a long time NDoc tool has been the best choice to generate API docs from source code comments. It is fast, reliable, easy-to-use and free. But unfortunalely NDoc project was freezed and is not supported anymore. It works only with .NET 1.1 projects.

Some time ago Alan Sheats during our e-mail conversation about software architectures recommended me three wonderful books. Here they are:

  1. "Domain-Driven Design: Tackling Complexity in the Heart of Software" by Eric Evans
  2. "Applying Domain-Driven Design and Patterns: With Examples in C# and .NET" by Jimmy Nilsson
  3. "Agile Principles, Patterns, and Practices in C#" by Robert C. Martin

First two of them concern the Domai ... Read More »

New version comes with some nice features including the .NET Generics support. For details see the project web site: www.MVCSharp.org.

Probably the main weakness of most Web applications is their uni-directional nature: a server can send data to the client only as a reply to his request. A server cannot initiate data sending to the client. And if something happens on a server, it has to wait for the client request, instead of notifying the client immediately.

Comet is a Web application architecture with bi-directional communication, when Client and Server are on equal rights, both being able to initiate data sending. Thus, if a Web application supports Comet architecture it becomes very close to conventional desktop (e.g. Windows) applications.

There are several approaches to implementing Comet, including Java applets and Flash applications running inside a client browser. Microsoft Silverlight-based Comet solutions are surely to appear soon and will be of great interest!

I'm proud to announce the first beta release of a new Model-View-Presenter framework. It is named MVC# and is very simple, flexible and has extremely nice features. For more information visit its web site: www.MVCSharp.org.

Whereas the Windows Presentation Foundation (a part of .NET 3.0) introduces pure .NET classes for drawing simple 3D graphics, its functionality may be not enough for feature-rich 3D applications. If this is the case, some more powerful graphics library may be required, such as OpenGL. Fortunately a managed .NET facade to unmanaged OpenGL dll's exists. This facade is a part of the Tao framework and allows accessing OpenGL functions from .NET applications as easily as it is done from managed C/C++ code.

Last few days I have been experimenting with OpenGL in .NET and have written a small application which visualizes 3D objects specified in a binary STL file format. The application allows moving and rotating the camera (eye point) and switching between different rendering options (sm ... Read More »

Sometimes building a software product from the source code requires more than just compiling. That is the case especially for big software systems where the build process consists of numerous steps.

A long long time ago (don't ask when :) the MAKE utility appeared to solve this problem. It offered a rather powerful scripting language for describing the build process. But time went by and new utilities came to substitute MAKE. They didn't have the drawbacks peculiar to MAKE and used XML as a script format. One of such tools was Ant and its .NET clone named NAnt. Microsoft suggested their own build tool too (well, that was expected :) under MSBuild name. Here I would not devle into MSBuild and Ant comparison, but I am going to list the things that really make MSBuild attractive compared to NAnt:

  • Tight integartion with Visual Studio IDE. Actually VS projects are MSBuild scripts. And modifying the project means just modifying the MSBuild script. An ... Read More »
