Windows Media Player Transparent Seek Bar How To

If you are a Visual C++ programmer or you have learnt Visual C++, you might have seen and wondered how Windows Media Player Seek Bar is designed. Well, I have always wondered about it before today..
The Seek bar which Windows Media Player is a transparent seek bar. It uses a gradient fill from bottom to top. When you are playing some video in Windows Media Player, you can see the video running behind this seek bar.
Many times I tried to design a control like this, where a control is transparent and the control which is placed behind this control should be visible. Although I never succeeded in this one, but I tried it a lot of times.
Today when I was listening to songs using Windows Media Player(!!), I saw when I click on the area near to seek bar Windows Media Player's main window gets de-activated. The technique behind the transparent seek bar is to create a separate top level window.
This second top level window should be a Layered Window, you can read more about Layered Window here. Now when ever you main window gets a WM_SIZE message, set the size of your second top level window as well. As the second window is layered, we don't need to repaint it again and again unless user interacts with this window.

    It stocks decencies and other system information. Making a change in those information does not only impact ms windows media player, but many other elements of Windows seven. Solving it can be done personally, but it is suggested to do it with a specific tool.

Spring AOP : JDK Proxy vs CGLib Proxy

One of the important feature in Spring is AOP. It is used by almost every enterprise application which is being developed using Spring. AOP So what is AOP? Definition of AOP - Aspect oriented programming is a programming paradigm which aims to increase modularity by allowing the separation of cross cutting concerns. Well, my understanding of AOP is - AOP allows us to introduce/join new modules in your project at pre-specified dynamic locations without having to code for it. Traditional examples of AOP is Transaction management, logging etc. You can read more about AOP at here .

Spring Custom Scope

Spring framework is one of the DI frameworks which is largely used to develop web applications(enterprise). It provides almost every feature which is required to develop a enterprise web application. Also it is extendable, so you can customize it the way it suits for your application. Custom bean scope Although bean scopes provided by Spring fulfills requirements of the application, some times you may need something different which is not available by default. In our application we faced the same situation. Requirement We had a requirement of the scope which uses an application value to decide which bean to use(return). The default scopes provided by Spring were not useful and was not providing the required functionality. Implementation As I said earlier, Spring is extendable. It provides an interface Scope, which you can implement to introduce custom scope in your application. To create custom scope, Scope interface needs to be implemented. Scope interface has ...
