What is Perl??

Perl (Practical Extraction and Reporting Language) , is an interpreted programming language with a huge number of uses, libraries and resources. Arguably one of the most discussed and used languages on the internet, Perl was first brought into being by Larry Wall circa 1987 as a general purpose Unix scripting language to process mail on Unix systems and since extended by a huge cast of characters.

Perl is a programming language which can be used for a large variety of tasks. A typical simple use of Perl would be for extracting information from a text file and printing out a report or for converting a text file into another form. But Perl provides a large number of tools for quite complicated problems, including systems programming. Programs written in Perl are called Perl scripts, whereas the term the perl program refers to the system program named perl for executing Perl scripts.

If you have used shell scripts or awk or sed or similar (Unix) utilities for various purposes, you will find that you can normally use Perl for those and many other purposes, and the code tends to be more compact.

Perl is implemented as an interpreted (not compiled) language. Thus, the execution of a Perl script tends to use more CPU time than a corresponding C program, for instance. On the other hand, computers tend to get faster and faster, and writing something in Perl instead of C tends to save your time.
Advantages:

Advantages :

Portability: Perl code that doesn’t use system specific features can be run on any platform, and these days almost every operating systems support it.
String processing and especially Regular expression support: Perl is a winner in everything related to string processing. Its regular expression support is the most versatile in existence and seamlessly integrated into the language. (In fact, it is so good, that Perl has set a new standard for regular expression, which is now emulated in many other programs and languages).
CPAN: www.cpan.org has a huge collection of free and reusable Perl code for many purposes – Science, system administration, Mathematics, Biology, foreign languages, database access, networking, etc.

no need to apologise, really!

some times at night when I flop on to the bed
I think of what I should or should'nt have said
everything seems to have happened by chance..
should I or should'nt I have cared for a second glance?

no one is all evil, not everyone perfect
its best not to have too much to expect
everyone trapped in their own little world
in their own actions and emotions they're hurled

its ok if sometimes I cant get
whats going on in your mind
there are some awkward pauses i'll bet
but its time to leave all those behind

so let you be you and let me be me

Flash Test paper1

Question 1

Step1

Create an XML file having information of 5 images.

Step 2

Load each node image of the xml file on the stage in a movie clip in such a manner that image will load at the center of the stage means there will not be any effect of resizing of the stage dimension.

Step 3

Set alpha 0 to 100 when each image appears. Provide buttons (Next, Previous) for navigation.

Step 4

Display height and width of each image in a text box when image loads.

Question 2

Create two buttons label (Circle, Rectangle) on clicking of each button draw shape accordingly on mouse movement

Question 3

Create a form in flash having information field say Name, Address, and Age.

User can enter information in these fields accordingly. If user closes this SFW file and again it open last field’s value should populated automatically.

Flash Test.. Try it

Drop circles on screen

Create a SWF that:

1. Starts with a blank screen.
2. When the user clicks anywhere on the movieclip, a small circle appears (around 25px in diameter) at the clicked position.
3. Each time the user clicks on the movieclip, another circle is visible.

Drag ’n Drop

Create an SWF that:

1. Has a single square present, 50x50 pixels in size.
2. Allows you to click and drag the square anywhere on screen.

Intermediate problems

MouseOver

Create an SWF with:

1. Three rectangles shown on screen, filled with Red, Blue and Green colours.
2. A textfield placed below the rectangles.
3. Whenever you move your mouse over a rectangle, that rectangle’s colour is displayed in the textfield.

Drawing

Create a SWF that:

1. Allows you to click-and-draw lines on-screen. Just straight lines, by clicking anywhere, dragging your mouse cursor, and releasing it. The line should start from the point where you clicked on and end at the point where you release the mouse cursor.
2. The colour of the lines you want to draw next can be changes using a ColorPicker.
3. Has a ‘Clear’ button. On click of this button, any lines on screen are removed, and you again have a blank slate to work with.

Advanced problems

External Image Viewer

Create an SWF that:

1. Has a textfield where the user can input an image URL.
2. A button labelled ‘show image’, on click of which the image referenced by the URL is loaded in an UILoader present on screen.
3. The user can pan the image (either using mouse drag or scrollbars) if it is too large to view.

Folder Creation-- Flash-- Not Possible

W can not make the folders or write any thing on our local using flash except for the shared object..

We can use third party tools like Zinc for that..

We can also use AIR for making that but these all are for desktop application.

web application cant do it ..

in Zinc we use it like this


working_folderLis.click = function (eventObject)
{
myfolder_br = mdm.Dialogs.BrowseFolder.show();
if (myfolder_br != "false")
{
working_folder.text = myfolder_br;
modules_combo.removeAll();
pageList.removeAll();
blankMc.unloadMovie();
refreshTracker();
refreshGlobals();
var _loc2 = mdm.FileSystem.fileExists(working_folder.text + "\\index_tracker.txt");
if (!_loc2)
{
mdm.FileSystem.copyFolder(mdm.Application.path + "\\att_common", working_folder.text);
mdm.FileSystem.copyFolder(mdm.Application.path + "\\metadata", working_folder.text);
for (var _loc1 = 0; _loc1 <>
{
mdm.FileSystem.copyFolder(mdm.Application.path + "\\sco_elements\\" + sco_folders[_loc1], working_folder.text);
} // end of for
for (var _loc1 = 0; _loc1 <>
{
mdm.FileSystem.makeFolder(working_folder.text + "\\" + empty_folders[_loc1]);
} // end of for
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\includes");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\images");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\html");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\css");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\audio");
initTracker();
disableBtns(false);
}
else
{
refreshTracker();
disableBtns(true);
} // end if
} // end else if
};
working_folder_btn.addEventListener("click", working_folderLis);

Web Service and BlazeDS Integration

We can Integrate web services and BlazeDS in flex application. We
need to follow some steps for setting the BlazeDS. Here is the
reference link:

http://learn.adobe.com/wiki/display/Flex/Creating+a+BlazeDS+web+servi...

For Amazon Web Services, it is providing the infrastructure for web services
platform only. We need the wsdl of AWS and write on the server side
configuartion xml file for BlazeDS.
