1) In Visual Studio, click on “Tools.” Then click on “Connect to device.”

In the “Connect to device” window, select the emulator desired, such as Pocket PC 2003 SE Emulator. Click on the “Connect” button. 

You will see the “Connecting …” window. If everything is OK, you will see the message “Connection succeeded.” Click on the “Close” button.

 
2) In Visual Studio, click on the “Tools” button. Then click on “Device Emulator Manager.” In the “Device Emulator Manager” window, you will see the Datastore tree with the emulator selected. The selection is marked with the green arrow:

3) Right click on the selected emulator and choose “Cradle.” This imitates putting the device on a cradle:

4) After this, the ActiveSync will run and allow you to set up a partnership. If you do not have the program, you can download ActiveSync. Select “Guest partnership” to avoid synchronizing with Outlook. Click on “Next.”

After this, ActiveSync gets connected to the emulator:

 

5) Go to Windows Explorer, copy the your_application_title.cab file and paste it in My Windows Mobile-Based Device.

You will see the ActiveSync message:

Click on OK to copy the cab file onto the emulator.

6) On the emulator, go to “Start,” then “File Explorer.” In the “My Device” folder, you will see the your_application_title.cab file. Click on it to install the application in the “Program Files/Your_application_title” folder.

7) On the emulator, go to the “Program Files/Your_application_title” folder and click on the application icon.

The application is running.

If you do not have Device Emulator Manager  in the Visual Studio Tools menu, you can run it the following way:

• In Visual Studio, click on  Tools > External Tools. Click on the “Add” button.
• In the Command box, use “…” to locate and select “dvcemumanager.exe.” By default, it is installed in the “C:\Program Files\Microsoft Device Emulator\1.0\” folder.
• If you do not have Device Emulator, you can download Device Emulator version 1 and Device Emulator version 2.

There is a well-known problem with exceptions in C++ constructors. Only objects that are constructed completely are deleted in C++. Usually, the developer is supposed to take special measures against the possible memory leaks. So let us look into what Symbian offers and what else can be done to solve the issue.

Suppose, there is a class:

class Container

{

                public:

                               Container ()

{

               thePart1 = new Part1();              

               thePart2 = new Part2();

};

                               ~Container()

{

               delete thePart1;

               delete thePart2;

 

};

                private:

                               Part1 *thePart1;

                               Part2 *thePart2;

}

If object c of the Container class is being created as a local object:

 

 void test ()

{

                Container c();

                …

}

and the exception  arises on c construction, then c’s  destructor is not called.

The results are that Part 1  and/or Part 2 are not deleted, and a memory leak takes place.

Symbian proposes to push the pointer to the newly created object onto the special stack – the so-called clean-up stack. In case of an exception, the clean-up stack is unwinded, and every pointer on it is deleted. So we could redesign our constructor the following way (for Symbian):

Container::Container ()

{

                               thePart1 = new Part1();              

                               CleanupStack::PushL(thePart1);

                               thePart2 = new Part2();

                               CleanupStack::Pop(thePart1);

};

Of course, it works and looks better than:

Container::Container ()

{

try{

                                               thePart1 = new Part1();              

                                               thePart2 = new Part2();

                                     }       

                               catch (…)

                                               {

                                                               delete thePart1;

                                                               delete thePart2;

}

};

 

But it could be made easier and more elegant by changing the pointers to smart pointers:

class Container

{

                public:

                               Container ()

{

               thePart1 = new Part1();              

               thePart2 = new Part2();

};

                               ~Container()

{

// nothing to do!!

};

                private:

                               auto_ptr<Part1> thePart1;

                               auto_ptr<Part2> thePart2;

}

 

Thus, we decrease the risk of memory leaks on exceptions. At the same time, we don’t have to release our resources in the constructor. It seems like we don’t need to use CleanupStack in Symbian at all – just develop an auto_ptr class instead:

template<class T>

class auto_ptr

{

                public:

                               auto_ptr (T *p = 0): ptr(p) {}

                               ~auto_ptr() {delete ptr;}

                private:

                               T *ptr;

}

Murano Software teams are comprised of dozens of skilled and experienced engineers. Every day, they face new challenges while developing our clients’ software products. The ability to find the right solution to a problem is one of the crucial elements that influence performance, readability, scalability, completeness and other qualities of a software product.

Since there are a lot of technology companies among Murano Software’s clients, the ways that our engineers solve diverse issues can be of high interest to our readers. We will cover the challenges with .NET, Java, Ajax, Ruby on Rails, SharePoint and other technologies.

You are welcome to comment on the posts. Our developers will be happy to share their experiences and discuss the issues.

Today, we start with Exceptions in Symbian C++ Constructors.

In the IT sphere, high quality of a product heavily depends on the abilities of its creators. According to many analysts, the number of companies that decide to outsource their search for high quality developers is increasing. That is why we will start our blog post series by looking into the quality of the technology resources that can be found in Russia.

As the Business Line columnist Vipin V. Nair notices, “Russia draws its software strength from its enormously talented pool of people.” In Russia, the abilities of IT developers are significantly enhanced by an extremely strong educational system, which is recognized all over the world. While, for example, “In India, students learn generic software skills, Russian students are taught advanced mathematical and computing techniques, which allows them to perform hard-core technical work,” says Vipin V. Nair. More than 40% of university degrees in Russia are in technology and science.

Russian software companies do not miss the opportunity to leverage that great manpower. According to a research paper by Market-Vision / EDC, 77.4% of Russian software companies employ PhDs, and in 45.8% of those companies, PhDs make up 10% or more of their staff. So by dealing with Russian outsourcing vendors, you get the opportunity to benefit from employing these highly educated engineers.  

Russian developers’ strengths are recognized by local market tech circles and global ones as well. A 2006 study by the FCREUE, the Haas School of Business and the UniversityCalifornia concluded, “In terms of education and experience with complex software development tasks, Russian programmers are likely to outrank all others.” of

Most analysts stress that very capability of Russian developers to manage tasks of high complexity and to find fresh and groundbreaking solutions to knotty problems. “Exceptionally well-educated developers who can perform extremely complex jobs, and a great understanding of engineering and financial services domains, are core strengths of Russia's outsourcing industry,” remarks William Martorelli, principal analyst at Forrester.

According to another study run by by Ernst & Young, Russia beats several other outsourcing locations in terms of skills and training of its IT workforce. You can see Russia’s top position from this table.

One of the ways for specialists to prove their knowledge and skills is to partake in high-profile contests. Russian technology students regularly win international programming contests. Russia has won the world's most prestigious competition, the Association of Computing Machinery (ACM) International Collegiate Programming Contest, 5 times over the last 10 years. For comparison, the USA has taken the first place only once over the same period, while India has not appeared on the top of this contest at all.

When reading this article, you may think, “Well, the Russian resources are talented, but their number is probably more limited to choose from, than, for example, in India.” Then here is some data for you. As it is written in the paper on BRIC layers by Economic Research from the GS Institutional Portal, Russia, being almost 80% smaller by population than India, its main competitor, produces even more tertiary graduates (16,765 graduates in Russia to 16,095 in India). In per capita terms, Russia has by far more graduates when compared to India (115 graduates per capita in Russia to 16 graduates per capita in India). As for technical PhDs, Russia has almost as many of them as Germany does and even in absolute terms leaves India far behind (about 12,000 technical PhDs in Russia to about 5,000 of them in India). Russia also outranks India in the number of workers with tertiary qualifications in science and engineering. Thus, you are sure to find in Russia enough specialists for all your projects to be realized.

Nowadays, Russia is increasingly considered one of the most attractive outsourcing destinations. SAP, Microsoft, IBM, Google, Boeing, Motorola, Reuters and IBM are only a few of the many global companies that employ local engineers and set up development centers in Russia. eWEEK named the Russian outsourcing industry as one gaining maturity and showing promise. The Indian outsourcing industry has to watch out, Business Line warns. Russia attracts technology outsourcing buyers, global companies and start-ups for a number of reasons.

The most substantial reason is a wide pool of talent with a high level of proficiency in diverse realms. “High-level thinking, strong English skills among key staff and executives, and a desire to break new ground on leading-edge projects are intrinsic to the Russian developers," says the eWEEK columnist Stan Gibson. This benefit is successfully combined with the lower cost and attrition rate that Russia offers.

There are also secondary factors that influence tech directors’ decision to outsource software development projects to Russia. Among them is cultural affinity of Russians with Americans and Europeans, the individual approach of Russian companies toward clients, the creativity and collaborative thinking of Russian developers, the Russian government’s new positive attitude toward offshore software development.

These factors can greatly influence your choice of where to assemble your offshore software development team. To make your choice easier, here, in our blog, we will publish a series of posts casting light on the reasons for outsourcing to Russia.

We are constantly improving our Web site to show you the essence of Murano Software. But how can you understand what the company is like if you don’t see its brains and soul: the specialists?

When working with clients, technology capabilities and services  play  a great role, but the most important thing in software outsourcing is the people who conduct the development process. Сhoosing the software development partner across the ocean and time difference, you probably would like to know who stands behind the company and drives its success.

Please visit the new section on our Web site – Our Team-Photos – to see some of the developers who turn the program code into the software solution for our partners’ businesses. There you can find photos of our working activities, corporate events and major holidays. We tried to show you the most memorable moments of company’s life and some personalities that stand behind our success. 

“McKinsey Quarterly” asserts that despite that the Chinese and Indian economies develop rapidly, their economy systems have strong barriers to growth.
At first sight India and China are very different: China’s main traits are a powerful banking sector and larger population while India’s strength is its equity market. Their financial systems also have different histories and evolutions. India’s financial and economic systems formed when they were still a  part of the British Empire. Their strong banking system is mostly due to Britain. China’s financial system formed in the second part of the twentieth  century when its government proclaimed a liberal course of economic development.
 

These two different countries with their differing economic systems have one common trait: a strong government sector that allows authorities to intervene in market evolution and influence the allocation of capital. As a result economy growth slows down. Chinese state-owned enterprises receive the lion’s share of investments in order to fulfill the plan of employment. The Indian government expends large sums for development of agriculture and the defrayal of the fiscal deficit.  In return private companies of both countries receive less investment and hold in the development. McKinsey suggests that China and India should create innovative financial systems that will increase efficiency and widen investment opportunities.
 

Different sources prove that Russia has a strong private sector and rich opportunities for investment; so many analysts suppose that this country is safe from crisis. Further development of the Russian economy may be reached by professional management, the growth of productivity and nonintervention of government. Russia has major potential of growth, especially in the IT sector that grew by nearly 20% in 2006. In absolute indexes Russian IT market yields to China and India in this industry. On the other hand, the IT sector, especially offshore outsourcing, grows rapidly. So in the nearest future Russia intends to occupy the deserved place in this sphere.
