Flash,Flex Vs HTML 5

I was checking the HTML 5 with Java script,CSS 3 and Jquery around since last 4 months.Also was keeping my eyes on this since 2008,but never get inspired to do anything.Now also I found that HTML 5 is still in the state where Flash was 7 to 8 years back.HTML 5 can replace maximum of simple banners and animated advertisements which were created using the flash.For that also the development cost is going to increase and quality will be not up to that extent as the Flash has provided long earlier.

But for the Audio/Video Streaming,Image manipulation,Gaming and Enterprise applications HTML5 needs to take still around 10 years.Also currently I don’t found any thing as impressive as AMF for the Client Server communication over the internet.The reason for this is simply that HTML 5 is also a markup language.You can check the link below,you will realize where the HTML 5 is in reality:-

http://www.w3.org/TR/html5-diff/

So the only thing which I will like to say is that Flash and HTML 5 will be needed in the same way
as earlier they were used together on the web.If you will try to replace Flash by HTML 5 for the small
purpose then you have to pay lot more then flash.And if you will be trying to create the Enterprise Application with HTML 5 then I think you will come back to Flex one day.Flash player is ruling since last 15 plus years,its not so simple to replace that.

There is a statement as below from adobe :-

For Flash Player releases after 11.2, the Flash Player browser plugin for Linux will only be available via the “Pepper” API as part of the Google Chrome browser distribution and will no longer be available as a direct download from Adobe. Adobe will continue to provide security updates to non-Pepper distributions of Flash Player 11.2 on Linux for five years from its release.

Thinking(Planning) of a Cross Platform Website/Application

First of all the word platform needs to be defined here in which respect I am using this word. Here the word is being used for the desktop /laptops and mobile/tablets.
Now at multiple times it is wrongly understood that if things are being developed for web-browser then those should automatically work perfect for the mobile too, but in reality it is not the case.
This understanding is not good for anyone.
This will Ok if you are simply having some simple html based website with some static pages that’s all. But what for the web applications which are playing with a lot of data, if one is assuming that he is going to offer the same page layout, or look and feel as he is having for the desktop based browser with only costing for the browser based desktop application then again he is going to cut the pocket of the mobile end users of that application due to the bandwidth prizing and limitations over the mobile browsers. Again over the mobiles/tablets there are different platform like iOS, Android, Windows Phone, Symbian, BlackBerry. So for which version the web application is being targeted again this is major question especially from the point of view of the money of the person who is planning to develop such application. So how one is going to manage this much of assets for accomplishing the above mentioned scenarios. What should be the best strategy to found such goals?
Also please not that no one even including the person who is planning such application doesn’t know how much success his application will be?
So what should be the best idea of thinking of such kind of web application, I will like to suggest that one should move step by step:-

Step 1:- First create you desktop browser based application selecting the capable techonology,which can offer you easy integration with mobile based applications. Please keep in mind that your service layer and business layer is going to be used later on by mobile based clients also, so the pc based version should have these things layers isolated.

Step2:- If your pc based application is going well then check the market scenarios for the mobile and find which one platform is capturing the maximum market or depending upon your end-user’s geographical reason figure out the largest market capturing mobile platform. Start developing the application mobile application which will be using the same service and business layer in Step 1.

Step3:- Repeat step 2 for the second mobile market capturing platform.
And so on………..

Hope the information can help someone to save money and give a good vision for his requirement.

Doubts about Flex and Flash

Since Last 5-6 days every one who belongs to Flex is having his own doubts and thoughts.The reason was the news that adobe discontinues development of Flash player on the Mobile Devices.

http://blogs.adobe.com/flashplayer/2011/11/focusing.html

My personal thinking is that the Flex and AIR both are not going to be effected due to this.As AIR is going to work continuously with the mobile devices.And Flex will be keeping to
rock on browser on the Desktop.Also flash players cutting edge technology will be carry on to
desktop browsers.

And the thing to mentioned here is that adopting HTML 5 will make at-least the clients vision clear.

Below is the official link which can make the things clear:-

Datagrid with multiLine variable height text Item Renderer in Flex

I was trying to get the multiline text inside the item renderer of a column and I tried a lot for this with multiple controls like TextInput, Textarea, Label etc by using the item render but was not getting the proper output.The thing which I was getting was that every item rendererer was taking the same height which was for the maximum height item renderer,and was not based on the content inside it.
The reason was only that earlier I was putting my these controls inside a Container and
there was sizing related issue for the container as I was not able to make different item renderes of different heights depending upon the text of the field inside it. But later I created my item render directly from the Text component and got the perfect result.

TypeError: Error #2007: Parameter blendMode must be non-null.

This is the error which make wasted lot of mine time.Finally I get to know that this will appear if we will using
any swc which is created in the advance versions of flex sdk main in 3.3 or 3.4 and we are created the project in the lower version of sdk e.g. 3.2. If you want to come out from this then either go for the higher or equal to the swc version of sdk for the entire application or rebuild your swc with the higher version.Hope this will help you if you will facing this non meaning title error

Byte Array to BitmapData and BitmapData to Byte array in Flex 3.

In the code below I am initially getting the byte array of my canvas with the increased size. Converting it into Bitmap data.And again converting that Bitmap data into ByteArray. So that you can use the particular step which one you require.
