Josh Birk has written a very interesting article on creating a Visual Force page to manage Streaming Topics. Its a very interesting read and there’s plenty of code covering the apex UI and backend code to pull the data. He also goes through the PushTopic object bound to field to perform the crud operations.
RIM should be very proud of how they have worked with the development community to build an amazing eco system prior to launch.
I am very excited about the potential for this platform and its all looking very promising based on the recent submissions to the app store. It’s been so busy that RIM have extended the 10k Developer Commitment until 8pm ET on the 18th Feb.
So keep coding and get those submissions in folks!
There are some very exciting times ahead for Blackberry developers. Don’t believe the negative press as there is a lot of great potential for us on the Blackberry platform.
Register now to learn more about the new Blackberry 10 Cascades Framework for building amazing user experiences in your software.
On the 14th Jun 2012 I will be off to the BlackBerry Jam World Tour. I have been getting heavily involved in mobile app development lately and it is important to keep up to date with the latest platforms.
I do actually believe that BlackBerry are making some very good moves towards the future and I am looking forward to developing on the new platform with a number of projects I have in the pipeline.
If your heading to the conference and would like to meet up then get in touch with me on Twitter @funcoder.
Iâ€™m a PC adverts are back!
I recently had a situation where I had a looper displaying images, each having a delete button. This delete button would actually delete the image file from the server, so I needed a way to confirm the action. In AWP you canâ€™t use the YesNo or Confirm functions in the server code but actually is very easy performing this in the browser code.
The important bit of code is the RETURN when the user selects No on the dialog. This RETURN will cause the browser not to execute the server code.
This is very handy to remember as there are many times when its good practice to get user conformation.
Now that the release 16 is approaching I thought it would be good to give some thoughts into what I would love to see in the next release. Iâ€™m just going to call it PC Soft What I Want but in the post I will be talking about all 3 products.
To start with I would love to be able to preview a template for testing rather than having to go to another page. If you try testing a template page you get an error.
Maybe one way would be able to specify in the template settings to page to run when testing. Its would just be nice to have to improve productivity.
In WebDev if you create a cell and set its background and opacity then the elements within the cell will also appear with the same opacity.
This is not great when you want to show text with say a crisp white colour. So how do you produce the effect without affecting the text?
Firstly you need to add an image control, set its Type to Generated.
Also make sure that you select â€œThe control can be overlaidâ€ on the image and then add a cell over the text. I usually set a background colour to the image to help me work with it in design.
Add a text control to the cell and set some text. Note that the Cell control also needs to be set as â€œThe control can be overlaidâ€.
Even though you set the background of the image you still need to generate a new background with the opacity. Its easy and only requires a few lines of code.
Note that you have to make sure the shape of the background is set to Solid Background for this to work.
