GPS Application tutorial & source code .NET

Introduction
What is it that GPS applications need to be good enough to use in a commercial environment, such as in-car navigation? Also, how does the process of interpreting GPS data actually work? In this two-part series, I will cover both topics and give you the skills you need to write a commercial-grade GPS application that works with a majority of GPS devices in the industry today.

One Powerful Sentence
This first part in the series will explore the task of interpreting raw GPS data. Fortunately, the task is simplified thanks to the National Marine Electronics Association (www.nmea.org) which introduced a standard for the industry now in use by a vast majority of GPS devices. To give developers a head start, I chose to use some Visual Studio.NET source code from my “GPS.NET Global Positioning SDK” component. (The code is stripped of features like multithreading and error handling for brevity.)

NMEA data is sent as comma-delimited “sentences” which contain information based on the first word of the sentence. There are over fifty kinds of sentences, yet an interpreter really only needs to handle a few to get the job done. The most common NMEA sentence of all is the “Recommended Minimum” sentence, which begins with “$GPRMC.”

Migrating from MS Access to mySQL

In an era where data becomes volumetric in every business, much attention has been given to proper database management and the ease of data access. Businesses that use Access begin to look for an alternative which allows better database performance, higher reliability, higher flexibility, yet inexpensive.

With the numerous choices available in the market, considering you don’t want to put too much investment on it, only one, MySQL, stands out from the crowd. MySQL’s flexibility allows you to deploy it cross various platforms, it also allows multiple user access concurrently. If you wish, you can still continue to do your data administration through Access as a front end. However, despite the various MySQL’s features overtaking Access, whether or not to migrate your data from Access to MySQL still need an in-depth consideration.

In this paper, I will firstly discuss about whether or not to migrate your Access data to MySQL. Then, I will cover about the considerations, planning and preparations which you should made before migrating your data. After all the planning and preparation stages has been finished, I will illustrate to you how the migration can be done with the help of Navicat, a MySQL database administration GUI.

Moving From Visual Basic To The VB.net Shoppingcart

The introduction of the VB.net shoppingcart caused a chasm to form among developers. This new computer language differed in many ways from the Visual Basic language that came before it. Like with all changes in any aspect of society, some people were very receptive to the new language and others wanted to hang on to the way that things once were. Since its initial release, the new VB.net language has been improved upon and more people are finding it to be an adequate developers’ language. However, not everyone has had an easy time making the switch.

When the VB.net shopping cart was first released, debate sprung up as to whether this was simply a new version of the old Visual Basic language or whether it should be considered an entirely separate product. While the basic idea of the language was the same, the implementation of it was very different. This is comparable to written languages, which use the same alphabet; the letters are the same but that doesn’t mean that someone whose primary language is Spanish will be able to read a document written in English.

The changes that were made in the new developers’ language essentially altered many of the interface features that existed in previous versions. People who like the new VB.net shoppingcart believe that these changes allow for a more open approach to new development. However, those who weren’t happy with the change felt that the new language was more difficult to work with and that the cost of learning and implementing the new system would be too high. Nevertheless, the new system has prevailed, albeit with some modifications.

For developers who are just starting to get used to VB.net, there are tools available to make it easier to make the switch. Microsoft’s VB.net website contains a learning center which provides information necessary to assist developers in understanding this new language. It has online papers and videos which break down the changes that occurred between the old Visual Basic and the new language. It also provides text and video data to assist with learning this new language whether you are a developer used to Visual Basic or a brand new developer.

In addition to the learning center, there are numerous tutorials available online. Microsoft as well as others have created these tutorials to make it easy to not only learn the general language but also to learn how to take individual actions on this new type of system. For example, someone who was designing a general VB.net e-commerce storefront but who didn’t know what steps to take to add the VB.net shoppingcart could hunt down an online tutorial and learn what needed to be done to add that cart.

Of course, not everyone is going to find that this language makes sense to them. There remain other languages out there that developers can work with. Some find that the open source versions of VB.net are easier to begin working with and provide more flexibility in creating new products. This may be particularly true of software developers who are working with the system and trying to create something that isn’t yet on the market. Other developers find that an entirely different computer language is the right course for them and may switch to working with non-Microsoft platforms to further their work.

The VB.net shoppingcart language seems to be something that is here to stay, at least for the time being. As more developers get accustomed to using this language, a more widespread appreciation of it may be seen. Inevitably, this system will be replaced by something else since the language of computers is always evolving.
