Ever wanted to take an Object into a format that is easily persisted and back? Well now you can. New in XE6 is the REST.JSON unit. This allows you access to TJSON a class with some very helpful class methods. Using TJSON you can convert an object to a JSON string and back with a little help from generics along the way.
The following code uses a class called TFoo that has a Foo and a Fee property (string and Integer) Using TJson you can then see how to covert the object to a string and back ready for storage, transport etc.
There were lots of amazed faces seeing how with Appmethod you can develop fast applications faster with Visual Live Bindings, access to BaaS etc and still have the applications as compiled native code! For those wanting to learn more quickly then I recommend the new series of 20 minute drop in Developer Skill Sprints running every Tuesday and Thursday (starting on the 29th May)
Data security is a hot topic right now, and one that is causing a lot of headaches. When it comes to securing your data and applications, small changes can make a massive difference. During the webinar there will be a number of tips relevant to whatever platform or database you develop with. We will also look at how to address a number of these challenges easily by exploring secure database storage with InterBase.
New BaaS components introduced in RAD Studio XE6 now make it easily to use remote data storage services offered by Kinvey and Parse along with Push notifications, File Storage and user authentication.
This can greatly reduce the infrastructure that you need to code, develop and manage with your application which speeds up time to market for including these features and can drastically reduce cost.
In the typical RAD, Object Orientated style there are a set of new interfaces behind the scenes that are implemented by new provider components that hook into the core components that work across providers, allowing you to code this effort once and work with it over Windows, Mac, iOS and Android.
In this short introduction video you will see how to work with the remote data store as an object persistence layer, learn about the new TBackendObjectList that contains the objects along with TBackendEntityValue to give you unique ID’s for each object without having to code that yourself, which is very cool indeed!
Last week I was on the road again, this time visiting Finland for customer meetings but mainly to lecture and help with student lab time at Jyväskylä University. This trip was part of our commitment towards education and arranged by the local partner for Delphi and C++ Builder in Finland, Moonsoft – @MoonsoftOy
Jyväskylä is about 4 hours drive from Helsinki and so I’m told the heart of a technical area where a lot of Nokia is based, so it was kind of fun to show off the Nokia X with Delphi App running that I picked up in Barcelona.
The lecture was hosted both in the university and streamed live and was the follow on to a number of sessions run earlier in the year by Juha Piispa from Moonsoft. After the lecture in the morning I had the pleasure of lunch with the dean before looking at some really old hardware, including what I was told was Finland’s first super computer and a massive IBM hard drive from before I was even born! Kind of geeky cool; before heading to the labs, where we had not 1 but 4 labs booked out (around 50 PCs) with students working together through a number of tutorials on http://docwiki.embarcadero.com learning about Visual LiveBindings, FireDAC and also the base language capabilities before running the output to both Windows preview and Android emulators / devices.
Unfortunately, I was so focused on what I was doing I forgot to take a load of pictures!
