web.sta – web-app, target browser is Internet Explorer 9 & 11

TextSystem – standalone desktop application, written in Java/Swing

IntermediateLayer – Client-Server app, linking web.sta and TextSystem together. 

web.sta can call TextSystem via the IntermediateLayer. IntermediateLayer creates an HTTP server for this purpose and web.sta simply sends GET or POST requests to the localhost. IntermediateLayer processes the request parameters and starts the TextSystem. There is no need for feedback calls, so the interaction scheme is simple and robust enough.

Citrix

In Citrix environment we can not create several listening sockets on the same IP address and port. It is necessary either to change the port, or to change the IP address. But Citrix provides a special mechanism for circumventing this restriction, without changing the algorithm of the program. This mechanism is called Virtual IP Loopback. The administrator simply configure necessary applications in the Citrix configuration panel and the application that uses localhost for socket connections will receive not 127.0.0.1, but an IP address in the form 127.0.0. <SID + 1>, where SID is the session ID of the Windows user.

The Problem

All this worked fine under IE9 (and with other browsers too) on Windows Server 2008 R2. And then the clients wanted something new and Windows Server 2012 R2 appeared with IE11. And the whole system stopped working. Regardless of Citrix IE11 settings, when specifying “localhost” it always tries to establish a connection to 127.0.0.1, but nobody listens there. After a little research, we came to the conclusion that this is a bug in IE11.

RoutingService

If the virtualization for localhost does not work out of the Citrix box for IE11, then let’s write it ourselves!

For these purposes, we decided to write a windows service, which will be the simplest web server, listen to 127.0.0.1 and redirect requests to the desired IntermediateLayer, based on the session number of the user. We did not find a simple solution to get the SID, but we immediately found SESSIONNAME in the environment variables. In IE via ActiveX we get the environment variable, pass it as a parameter to the HTTP request. In RoutingService by the sessionname through wtsapi32.lib we get the session number. Then we redirect the HTTP request and return the response to IE.

Something went wrong

We began the testing and integration of our service. But not everything went as smooth as we would like.

As it turned out, the name of the session can be changed, although we did not understand in what conditions it happens. But often it happened that the session name changed, and IE11 only knows the initial value of the environment variable. And persistently passes this value to the RoutingService.

What is in the registry?

It is necessary to find another way to get the sessionname. We have looked for information about sessions in the registry and that’s what they found: in HKEY_CURRENT_USER \ Volatile Environment we can get a list of sessions of the current user.

If the user session is one, then everything is fine, we can read and use it. And if there are a lot of sessions for one user, then we need to somehow determine which session we are in. We could not come up with anything better than matching the path to the temporary files folder.

Here is an example:

In IE, we get the current path to TEMP using ActiveX Scripting.FileSystemObject.

This way we managed to get the name of our session. But that’s not all. The value of the keys under the Volatile Environment is, in fact, the SID is. That is, we can immediately get the necessary IP address in JavaScript and send a request to it.

Shall we simplify it?

Finally we can get the SID and establish a connection directly, without using RoutingService. But the solution still does not look beautiful. Studying the Internet showed that the problem exists, but the solution to this problem is not described anywhere. And the Microsoft keeps silence as well. 

We hope someone with this specific problem can benefit from our experience.

If you are planning to use software development service in your business, this review will offer five reasons why you should go for SaaS solutions. The SaaS applications run on servers of different SaaS users and providers and are accessible through browsers. Rather than purchasing an application, as a user you pay a rent’, which allows you to utilize SaaS for a certain period of time. This means you will be able to reduce the use cost overtime. 

What are SaaS Based Solutions?

SaaS i.e. software as a service refers to a mode of software distribution whereby a third-party provider often hosts apps and makes them readily available to different clients online. Software as a service is among the three prime classes of cloud computing, apace with PaaS (platform as a service) and IaaS (infrastructure as a service). Some of the examples of SaaS include GoToMeeting, Common SaaS Use-Case and Google Apps among others. Here are reasons showing why you should go for SaaS based solutions when the need arises:

5 Reasons Why You Should Go for SaaS Based Solutions 

Lower Up-front Cost

SaaS generally is subscription-based not to mention it does not carry any up-front license charges, which makes it possess a lower initial cost. The management of the IT infrastructure which runs the software is performed by the SaaS provider and therefore the charges for software and hardware maintenance are very low.

Easy Upgrades

Easy upgrades solution is another merit that makes SaaS a suitable alternative over the conventional models of software installation. With this application, the SaaS provider will help in tackling the software and hardware updates for you. The provider deploys upgrades to the hosted apps and hence removes this responsibility and workload from you.

Accessibility and Scalability

In order to obtain a SaaS application, an internet connection and a browser is all you require to have. These things are generally present on a wide array of gadgets and from any place globally, which makes SaaS to be easily accessible when compared to the conventional business software.

SaaS providers provide a range of subscription alternatives and flexibility to adjust subscriptions when and as needed. Therefore, with SaaS based solutions, as your trade grows or when number of users that require acquiring the services increase, you can change subscriptions easily.

Setting up and Deploying SaaS is Quick

SaaS as an application is not only already installed in the cloud, but configured also. By SaaS being quick and easy to set up and deploy, this helps minimize typical delays which often result from lengthy conventional software development applications. 

It is Cost-Effective Alternative Generally

SaaS can offer notable savings due to several factors. For instance, it can help you eliminate the upfront price of installation/purchase, and on-going costs such as upgrades and maintenance. Rather than spending huge amounts of cash on hardware installation, SaaS based solutions can be downloaded as well as maintained easily.

Bottom Line 

Utilizing SaaS based solutions in your business can help you save both time and money. Using SaaS is therefore worthy since you will be exposed to a range of merits. Furthermore, unlike the conventional software development applications, the maintenance responsibilities of SaaS solutions will not be handled by your IT department, but by the vendor themselves.

Nowadays, the proof of concept (POC) has become more or less a standard procedure in most software development companies. POC is used to assess the viability of a product in a real market environment, where true business needs exist. In one of our previous articles, we’ve already covered how to structure POC and what goes into it exactly.

Today we’ll go beyond simple requirements and processes and talk about setting your business goals straight in order to deliver the POC, your customers will appreciate.

One conversation that is often missed, when talking about POC, is how is it actually benefit the client? So here at IntechCore, we’ve compiled a small checklist to help you stay on track and think customer-first during the proof of concept.

Identify Decision Makers

Note: decision makerS.

Very often, most companies only envision their client as a single person with whom they communicate. But most businesses don’t function in such totalitarian regime. There are multiple people who run the company and influence the final decision:

  • Business owner
  • CTO (chief technical officer)
  • Financial manager
  • Marketing lead
  • Etc.

In order for you to deliver and present truly stellar POC, you need to think about how all these people will see it. Because if you prove that the product in mind has an incredible technical application but don’t present a clear mean of marketing it, the whole project might be in jeopardy.

Define Success & Align Expectation

Perhaps the most important aspect that is getting missed all the time. You’ve helped your client launch MVP (minimum viable product), and you gather some feedback. What comes next? You haven’t actually defined any measurable criteria of success. Here are a couple of questions you might want to ask yourself and client before even starting:

  • Why are we doing this and what are we trying to achieve?
  • Which other product on the market are we competing against?
  • With what other software can we compare the product?
  • What’s right or wrong with the way we launch MVP?
  • What’s the real value of the product?
  • Who will maintain and upkeep the product?

By asking these question, both you and the client might uncover some previously obscured challenges or prospects.

Also, these questions will help you in aligning expectations with customers and avoiding the situation where the client has unrealistic forecast.

Know What to Do Next

After a successful completion of POC, for a software development company, the logical next step is receiving a paycheck. But it doesn’t have to be this way. Having better clarity on the next steps required by each party increases the trust between companies and strengthens their partnership.

If you do a bit of extra work and strive to go beyond simple MVP launch, then you might find yourself in a position, where you have a loyal customer base who entrust you with their future projects and will mention you as a trusted partner in the future.

 

Every software development company out there knows, that no matter how polished your internal processes are, things never go as expected. Software development is one of the most challenging and at the same time competitive industries today.

So naturally, every major business in this field strives to improve its productivity and optimize workflows to overcome most common challenges.

But what exactly are those challenges?

  1. Assembling requirements

Poorly defined requirements come down to simple “Garbage in. Garbage out”. The difficulty in requirements gathering almost always associated with miscommunication between client and software development vendor.

Sometimes the client lacks certain technical expertise and therefore puts in front overly-optimistic expectations. Sometimes software developers cannot translate technological limitations into business perspective. Regardless of why it happens, made-project changes in requirements always cause delays, revisions and additional expenses.

  1. Estimation & roadmap planning

Estimation of cost and clear planning happens at the very early stages of product lifecycle. And we all know that it is impossible to account for everything. It’s always a difficult task when you have to explain to the client that some deadline needs to be extended. So it’s very important to establish maximum transparency between two parties and keep communication lines on at all times.

  1. Staying on top of the technology

This one is a clear responsibility of software development company. Staying on top of tech trends and be able to accommodate most innovative business requests is very important because the technology changes at a rapid pace. That is why it falls down on companies to continuously educate their employees and make sure that they as a business stay competitive.

  1. Multiple testing & QA iterations

The best companies in software development sector have realized long ago that Testing and QA should never come as an afterthought or post-production process. Various iterations of testing need to occur throughout the project cycle.

And when you investigate the entire system, there will be bugs found. Many times the problem needs to be isolated to let the rest of the project move on. But in some cases, it is simply impossible and you reach a complete roadblock that slows down the development time.

IntechCore Software Development Services

Only by employing innovative methodology in managing remote teams and staying on top of trends can software development company survive in the competitive market. Here at IntechCore, we structure our internal workflows deliver exceptional results, information security and increased productivity.

Every day we work towards overcoming industry’s biggest challenges and delivering our customers the exceptional-quality software. We pride ourselves on succeeding in most demanding projects through continuous monitoring of progress, cost, and delivery.

The answer to the question why it’s essential to create high-quality software is logical and understandable for all parties of the development process.
Obviously, any customer wants to get a high-quality software product that meets all the established requirements, is possibly cheaper and delivered at the allocated time, so as to prevent future maintenance costs, problem search, errors, etc. On the other hand, software developers are seeking to perform their work on time and with maximum quality, in order to reduce their costs for the warranty period. Therefore, both parties of the software development process pursue at least two identical objectives: to deliver the software product on time and to achieve the highest possible quality of software.

At the present day, technology is the backbone of virtually everything we do. From simple personal tasks to complex industrial processes, we are relying on software to get fast, accurate and reliable results. In this digital era applications are helping us manage business, socialize, communicate, automate business processes, increase productivity, enhance security and much more, and this makes technology an integral part of our lives. With the advancement of technology, the software development process has evolved as well. The world is demanding for applications that are efficient, fast, reliable and easy to use; this means that developers must focus more on strategic planning in software development so as to achieve the best results possible. Planning is a crucial phase in the development process, as it determines the level of success and reliability of an application.

Strategic planning in software development involves setting objectives, focusing on the architecture and design, deciding on the development timeline and concentrating resources and efforts. A strategic plan helps developers layout a framework that enables them to work toward achieving the goals in the most effective and efficient way. Below are some of the roles and values of strategic planning in software development.

A Well Thought Architecture

An application and its efficiency is only as good as its architecture. Developing fast, efficient and reliable applications starts with the software architecture; it is what determines its performance when in use. Strategic planning helps the developer focus on the various software architectural elements that make an app more reliable; these include security, speed, efficient memory footprint, and stability. Developing an app without a solid plan means the app might have security issues, frequent crashes and be slow during operation, whereas strategic planning helps eliminate this issues.

Improved Quality

Focus on strategic planning in app development helps the developer build excellent quality. An accurate plan helps the developer start the development with the end in mind and this way the objectives are accomplished. Every application is developed to solve a particular problem. App development with a strategic plan will solve the problem in the most efficient way, and the users will be satisfied with the results. The quality will determine its success in the market.

Timely App Development (Time Management)

Statistics show that most applications are not completed in time and this leads to inconveniences or at times renders the software useless. An app that was meant for a specific event like national elections has to be complete for testing and implementation before the elections begin. Unless the software is complete before the event, the development process will be a waste of time and resources. Planning helps the developer layout a development schedule. The schedule outlines the tasks to be completed in each phase, and by following this program, it is possible to develop and complete the project in time.

Cost Reduction

Software development is a costly process that requires both resources and time. A strategic plan helps the developer come up with a plan that describes the guidelines and specifications of how the app will be developed. With a good design and architecture, it is possible to develop the software with the allocated resources. Without a good plan developers may work for weeks or months just to realize they are heading in the wrong direction, and this leads to waste of resources, while a good plan can help reduce these costs.
