I would agree with Henrik. Using the Vector class would be better in this
case (or if Vector is confusing even just Array - Vector is just a typed
array where you declare the data type and enforce it). And doesn't seem to
me you need to separate hour digits from minunte digits - you're just
dealing with numbers 0-9. Here is an example.
Instead of this: hours_digit1[1] = new Bitmap(number_1_image);
hours_digit2[1] = new Bitmap(number_1_image); hours_digit3[1] = new
Bitmap(number_1_image); min_digit1[1] = new Bitmap(number_1_image);
Do this:
var digitBitmaps:Vector.Bitmap = new Vector.Bitmap();
for (var i:int = 0; i9; i++)
{
digitBitmaps.push(new Bitmap(number_+i+_image));
}
Then, to get the image you want do the following. Say you wanted to get the
number 7:
var image7:Bitmap = digitBitmaps[7];

Ok, so forgive me as I have never used this before and am new to AS. I
want to load a series of 10 images, these will be numbers in a countdown.
Its possible for an image to be used 7 times at once (111:11:11). If I
want to use the same image would I load the image into BitmapData, the turn
around and have a series of Bitmap objects for every digit?
clock_image_loader.addEventListener(Event.COMPLETE, images_loaded);

number_1_image = Bitmap(LoaderInfo(event.target).content).bitmapData;

then do something like this?
hours_digit1[1] = new Bitmap(number_1_image); hours_digit2[1] = new
Bitmap(number_1_image); hours_digit3[1] = new Bitmap(number_1_image);
min_digit1[1] = new Bitmap(number_1_image);
and so on? this would mean I would need a declaration for all seven digits
for 0-9.
(This is tossed together but I think you get the idea.)

Re: [Flashcoders] Getting Data into my SWF
Thanks to everyone for all of your responses. What is going to happen, is the application is going to hold a coupon. That coupon will be retrieved from a database and passed into the Flash application. I guess as I am writing this, the script will just check the date and if it is not correct, it can simply not return the coupon. My question revolved around a user manipulating the date passed into the flash application and causing the coupon to show up before the countdown is really up. Thanks very much.

Is the problem that Kevin doesn't want the client swf to hold the date for fear of it being known? If so, a key could be sent instead that relates to the download date and stored in the database. Each time the swf runs it sends the key and the server checks that against the date. John On 14/03/2011 12:19, Developer wrote: No, I get it. The client and data transfer are insecure.

Re: [Flashcoders] Getting Data into my SWF
@Jord - The date will be passed in or retrieved from a script and would be the server date. My concern was that the date would be intercepted/modified in some fashion, but since the end result is retrieved from the server, the server script will just have a check to make sure the date is right to release it.

[Flashcoders] Getting Data into my SWF
Hello, I am very new to implementing Flash and ActionScript so forgive me if I am way off base. I have an application that utilizes the date and time. It is imperative that this is correct and not from the client's machine. To get the server date/time, I can pass it in as a FlashVars or I can call a PHP script from within Flash and load the date as returned data from the call. Is there another way? Is one way more secure than another? I have read FlashVars is not safe but it always referenced passing passwords in. I am not concerned with the user SEEING the data, I just don't want them to be able to load the SWF in a way that they would be able to pass in their own values. Also, in a similiar fashion, I want to load some data from a database. I am using a MySQL backend and figure to use a PHP script to do the data manipulation I need then call the data from within my ActionScript. (Essentially, I am going to be loading some images from the database based on criteria, then I want to be able to use those in my flash application). Thanks for your patience and help.

Re: [Flashcoders] Getting Data into my SWF
I'll explain further so I get valuable responses and avoid the sarcasm. My goal is to pass in the date from the server, the application counts down, and when the date hits a certain time, the application does something. This something that the application does will also be loaded by calling a PHP script that will load from a backend DB. My concern is someone being able to launch the SWF passing in an incorrect date that will trigger this something early. Thanks for your help.

Okay I have the following code:

public var mainMovieClip:MovieClip;
public var printMovieClip:MovieClip = new MovieClip();
var bytes:ByteArray = new ByteArray();
.
public function printCoupons(ev:Event) {

myPDF.setDisplayMode ( Display.REAL );
bytes.writeObject(mainMovieClip);
bytes.position = 0;
printMovieClip = bytes.readObject();
printMovieClip.removeChild(printBtn);
printMovieClip.scaleX = .9;
printMovieClip.scaleY = .9;
// we add a page
myPDF.addPage();
myPDF.addImage(printMovieClip);
When I click the print button, I am receiving an error:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at Coupons/printCoupons()
I don't understand what the null object is. When I remove the
attempted clone of the object, the export to PDF works great, but I
don't want the scale to effect the actual canvas.

Good afternoon, I wrote a little flash app that loads coupons from an XML file and formats them to display on a webpage. When going to print these, I simply sent the canvas to the printer. However, the side of the coupons are cut off.
