General Concepts about Object-Oriented Programming

General Concepts about Object-Oriented Programming

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.

Tips to Solve – Error 4294966746 JET_errDatabaseInconsistent in MS Exchange Server

Tips to Solve – Error 4294966746 JET_errDatabaseInconsistent in MS Exchange Server

An Exchange Server database is susceptible to different corruption problems, such as dirty database shutdown, antivirus scanning, log file issues, and others. Thus an administrator might require different Microsoft Exchange Recovery tools to solve such problems and to continue working the e-mailing environment.

Further is a scenario that depicts a similar situation of Exchange Server database corruption. As an Exchange Server administrator, you may observe one or more of the below symptoms:

1. You cannot start and/or Information Store service
2. Exchange clients lose the ability to send or receive e-mails. You cannot solve this issue by restarting the server
3. You restore the database from an offline backup but the database is still inconsistent. On running Isinteg utility (database integrity check), it gives the below error message on screen:

“Error 4294966746: JET_errDatabaseInconsistent”

Cause

Information Store is corrupt. Either both or one of public store and private store is corrupted.

Solution

Before trying the below steps, you are recommended to take the backup of the entire Information Store to prevent any post-crash consequences. Use the below steps in order to solve the above problem:

1. Analyze all the error message and events of application event log that Exchange reports on attempting to start the Information Store

2. Run eseutil /mh command to check the integrity of Exchange databases (Priv.edb and Pub.edb). An inconsistent database shows ‘Dirty Shutdown’ state but is not always corrupt. This state can also occur if all the transaction logs have not been committed yet.

3. Replay all the transaction log by performing soft database recovery. For this, execute eseutil /r command for the affected database(s).

4. Run hard database repair in case soft recovery doesn’t work. Run eseutil/ p command and delete all the .chk and .log files

5. Check if the previously occurring symptoms go away. If you can successfully work with the database(s), they are repaired. Next, run eseutil /d and isinteg -pri -fix -test alltests commands in sequence to defragment and fix database issues respectively.

6. In case, the problem remains the same, use a third-party Exchange Server Recovery tool to diagnose and repair the database more effectively. A Microsoft Exchange Recovery utility uses safe, yet powerful, scanning procedures and allows for easy database repair.

Microsoft Exchange Recovery Tool is a professional utility that repairs corrupted Exchange database and extracts the mailboxes in individual *.pst files for Exchange Server 2007, 2003, 2000, and 5.5. The tool provides advanced Exchange Server Recovery features and is easy to use. It can also recover deleted mailboxes and inaccessible STM data.

Finish Hardware Makes The Door

Finish Hardware Makes The Door

Doors in commercial facilities require a minimum of finish hardware, including hinges, flush bolts and pivots. Doors can also be outfitted with a variety of decorative hardware, including kick plates and door pulls. Which hardware is installed is determined by door use, architectural style and safety concerns.

A hinge may just seem like a hinge, but each hinge is designed for use in a particular situation. For example, a basic five-knuckle plain bearing full mortise hinge is designed for use on a standard weight door that gets little use. It also cannot be used with a door closer. On the other hand, a three-knuckle spring hinge can be used with a door closer. When choosing hinges, tell your supplier the weight of the door, the expected traffic level and the details of any other devices that will be installed on the door. This way you can get the correct hinge for the job and not find the door literally coming unhinged in the future.

Doors can also be fitted with pivot sets. These are typically floor-mounted, although some are jam-mounted. Pocket pivots are also available. These allow the door to open flush to the corridor and are commonly found in hospitals or other settings where the door needs to be completely out of the way when open. Just like hinges, pivot sets need to be chosen based on the weight and expected usage of the door. Pivots are available for doors from 200 to 500 pounds. Some pocket pivots are also rated for use on fire doors.

Flush bolts and strikes are designed to work either on metal or wood doors. Options for this hardware include manual flush bolts, automatic flush bolts, constant latching flush bolts, auxiliary fire latches and dust proof strikes. The best flush bolts share some common features: meet ANSI A156.3 Type 25 or Type 27, are non-handed, offer optional dust proof strikes, and have low actuation forces. You’ll need to know how the door frame is prepared when ordering flush bolts.

Put the finishing touches on a door with decorative, yet functional hardware. Kick plates and push plates protect the door from damage. Pulls can be coordinated with the decor of the building. These items are available in a variety of finishes. Floor stops, wall stops and door silencers all improve the function of the door. Even these hardworking items are available in styles to complement the building design or to blend unobtrusively into the background.

Finish hardware should be chosen carefully to ensure a door works properly and safely for many years. Although home supply stores may carry some basic hardware, it’s best to rely on an knowledgeable commercial hardware supplier to get the proper hardware for each installation.

Hardware Transitions Using Adaptive Restore,

Hardware Transitions Using Adaptive Restore,

Windows, like most operating systems, is extremely sensitive in regards to hardware. This makes replacement of failed hardware or even hardware updates difficult at best, impossible at worst. New hardware sometimes lacks drivers and Windows often has configurations that lead to the hardware not being recognized. This is a frustrating and problematic reality, but Adaptive Restore can resolve these issues quite efficiently, making hardware changes effective and efficient.
The program fixes the Windows kernel, makes HAL compatible with new hardware, tracks new and old hardware, determines what is required (drivers, network cards, connections, etc.) for Windows to recognize the software, searches through a Windows repository for the requirements, and installs everything automatically. In the event the repository lacks the necessary driver, it will seek user intervention either to be pointed to another repository or to accomplish manual driver installation. After the diagnostics and installation, the program makes sure that all components are actually enabled, which ensures that the newly added hardware interfaces with the operating system.
The software can perform all of these functions automatically or can be operated manually with a skilled user. In a manual mode, the program displays available information on drivers needed, installed, and missing. It does the same with hardware component status. Then, it allows the user to manually direct the installation of the drivers. An option is available to force install all drivers from a repository, whether or not hardware immediately requires it or if it already has the driver.
Adaptive Restore also streamlines the virtualization process. Many times, new systems are not desired when creating virtual machines. It is often better for a company to create virtual versions of existing physical systems instead. Using archive data, this software accomplishes that goal. The software creates a virtual replica of the original physical machine, which makes the transition from physical to virtual much easier. Continuity is maximized using this process, and productivity loss is reduced during the virtual migration.

Oftentimes, companies hold back on necessary migrations because of the fear of downtime during the process. Replacing hardware is far easier and faster with the help of this software, and it makes for simpler transitions to virtual platforms. All of this is accomplished without a sacrifice of administrator control. Interruption of workflow represents lost profits and ongoing corporate risk. Companies should investigate all options that can minimize the exposure that idle time can create. In the ongoing management of IT requirements, Adaptive Restore is a valuable resource for business continuity during technical transitions.

Programming Tutorial Android Development; Andengine

Programming Tutorial Android Development; Andengine

Finally Ive been able to check out the Game programming for Android. Ive found several Android game programming tutorials out there, but none of them were really exciting or user friendly. However, I was able to find an open source game engine which makes the life of a programmer a lot easier when it comes to game programming for the Android platform.

Andengine

The Andengine is an open source, free game engine strictly aimed at the Android platform. It offers Physics such as gravity or collision checks to the developer. Its based on OpenGL and offers a lot of functions which make the life of a game developer a lot easier. The advantages of this game engine are that you dont need to mess around with OpenGL directly when programming games for Android. You get some easy to use and fancy classes, so you can develop fast and efficient games in no time! Also this game engine is being developed on right now, so its not like a game engine which is dead and has a low user base. Its very wide spread and there are a lot of apps out there on the Android Market (obviously games) which were programming using the AndEngine. However, there is one problem with this game engine, which will probably scare away a lot of users; the documentation. The game engine might be coded fine and you can view the source code, but there is no or low documentation. There are examples out there for basically anything your game developer heart desires, also there is a community that will be glad to help you out, but there is no Javadoc for example, which is a badly wound for the AndEngine. However, its open source and free, so you cant expect more, its just great!

My own experiences with the Andengine

To be honest I havent had that much experience with the AndEngine. I have just been playing around for a while now with the examples out there and I will soon post some game tutorials in the near future on this blog, so you can get a feeling for the AndEngine. However, it seems that stuff which should be very easy to do, such as loading a picture into the memory, is not that easy using the AndEngine. Let me put it in another way, it is easy and user friendly, but its not very intuitive, you will need to get a feeling for the AndEngine first, if you have been programming with other Game development kits or engines, it has its own special approach. However, the code is very readable and well maintainable. Also the source is very well written and basically anybody with some Java and Android knowledge will be able to understand the source code more or less.
