CFMobile Example – Accessing remote data from mobile application

So far I have posted CFMobile examples that were mostly standalone applications (except a photo application that uploaded image to server). However many mobile applications may need to interact with server, for example to show data from a remote database, to modify data or for many other purposes.

CFMobile features in ColdFusion Splendor make accessing remote CF server very easy. I will demonstrate this using a simple example – I will build a mobile app that displays employee records fetched from a remote CF server. The client side (cfclient) code calls a CFC on the server side which fetches data and returns result to the calling page. You will see that creating and accessing a server side CFC is as easy as it is in a completely server side CFML code – you don’t need to worry about writing code to make AJAX calls. cfclient does that for you transparently. I should mention here that this feature to call server CFCs from cfclient is not limited to mobile application, you can even use it for any web application.

Here is a screenshot of the application –

CFMobile Example – Record and playback audio using ColdFusion Splendor

In this post I am going to show how easy it is to record audio and play it back in a mobile application using ColdFusion Splendor. If you haven’t already, you can download it from Adobe Labs.

I have tried to keep the application simple. There are two buttons, Record and Play. When you click Record button, the recording starts and the Stop button is displayed. Speak into the phone microphone to record your voice. When done, click Stop button. You can play back the audio by clicking Play button. You can also stop playback any time by clicking Stop button.

Here are the screen shots –

ColdFusion Thunder – It's all new IDE

Though ColdFusion Thunder is the next version of ColdFusion Builder (the last version was 2.0.1), it is like a new IDE because it’s a major re-write. Past versions of ColdFusion Builder were built on top of Aptana. I had noted some of the challenges in implementing ColdFusion Builder a couple of years back, when CFB 2.0.1 was released.

ColdFusion Builder (till version 2.0.1) used a very old version of Aptana. Aptana later re-wrote and improved their IDE and released it as Aptana Studio 3.  The integration points in Aptana Studio were changed to such an extent that integrating CFB in it would have meant re-writing it. So we decided not to base ColdFusion Thunder on Aptana and implemented many features that Aptana had contributed earlier – most notably editors for HTML, JavaScript, CSS and XML. This also meant CFML editor had to be re-written because it was based on Aptana APIs to integrate HTML, CSS and JS editors in it.

The task was huge and we, in the ColdFusion team, had been working very hard during the past two years to – first build all (or most) the features of CFB 2.0.1 in Thunder, and then to add some more features. If you have used ColdFusion Builder in the past, then you will see great performance improvements in all the editors in Thunder. Specifically you should see difference when editing large files. The memory footprint is also improved.

Here are some of the new/improved features in Thunder –  Continue reading “ColdFusion Thunder – It's all new IDE”

CFMobile Example – Taking picture and uploading to ColdFusion server

In this post I am going to show you how to create a mobile application using ColdFusion Splendor that can take a picture and upload the picture to CF server. This application uses Camera and File APIs.

The application is very simple – it has two buttons, one to take picture and the other one to set URL where pictures are to be uploaded. You can set URL of the server before taking a picture or after, just before it is to be uploaded. Once the URL is set, it is stored in the localStorage and will be remembered.  There is a messages div where the application displays messages about different operations it is performing.
