Some .Net applications are required to run as single instance process (at startup, each process “ensures” that he’s unique). This requirement may come from licensing issues, technical and/or other reasons. Quick search in Google will provide a variety of solutions , most of them are based on WindowsFormsApplicationBase object from VB.Net, usage of Mutex object and other techniques. I don’t like mixing VB with C#, and also Win-Forms solution isn’t “pure” enough for WPF applications. So I wrote my...
This solution can be used in WPF and in WinForms (with some improvements). Many times UI programmer needs to activate window, the activation can be done by using “Activate()” function in window. The problem is that this function will not show window if it is minimized. In that case you can use this workaround: using System ; using System.Windows ; namespace Test { public partial class MyWindow { ...

Recently I’ve required to add Mouse-Wheel support in some of our Silverlight projects. Quickly discovered that unfortunately this feature isn’t supported in Silverlight 2.0. I found some post with sample code that solves this problem and made some changes in “MouseWheelHelper” class, also added “UIElementExtender” class that extends classes that derived from "UIElement"....
I want to present very useful feature “ XAML exporter for 3D Studio Max ”. This feature contains number of MAX-Script files with code that allows exporting 3D scenes from 3D Studio Max to XAML files. “Max2Xaml” Project on Codeplex website: http://max2xaml.codeplex.com . I’ll try to present a simple guide for this feature with some useful example.

If .Net project contains embedded resources, we can extract them at run-time (for internal-in-program usage or to save as files). Embedded resource can be attached file of any type (popular types: texts, images, sounds). This post will show how to use assembly functions for resource extraction and how to read/write these resources into files/variables ...

Analog clock is very cool feature, most windows users like analog clocks, we can find them in Google-Gadgets and other desktop programs. I've written custom control a few years ago (in .Net 1.1) and rediscovered it two weeks ago in some of my projects. It is very simple (can be extended and improved) and provides clear example how to build custom controls in .Net (C#). Challenge for those who moved to WPF: if you have some time and motivation, please write analog clock in WPF and publish the...
