Actionscript :: Calculate The Difference Between Two Date Objects, In Months?
Feb 16, 2011
I have to validate that 1) the end Date is not less than the start Date and 2) the difference between the two UTC Dates is not more than 12 months. To do this, I need a monthDifference function:
public static function monthDifference(start:Date, end:Date):int;
Since partial months can be confusing, this is how month differences are supposed to work:
The month difference between January 1, 2010 and January 31, 2010 is zero (0).
The month difference between January 31, 2010 and February 1, 2010 is one (1).
The month difference between January 1, 2010 and February 28, 2010 is one (1).
The month difference between January 1, 2010 and March 1, 2010 is two (2).
How can I calculate month difference in ActionScript 3.0?
I am trying to create a 30 day trial period limitation in Flash CS3. I am having a problem with checking the number of days. I am using zinc mdm to get the date of an external file. Following is the code I am using.
var d1:Date = new Date(mdm.FileSystem.getFileDate("c:\myText.txt")) ; var d2:Date = new Date(); //(Date2 - Date1)/
I have a calendar written in Flash (ActionScript). The calendar displays events on it. I am seeing an issue today (March 31) with any months that have less than 31 days in them. Here's the code:
myDateate = new Date(); myDate.setUTCFullYear(2011); myDate.setUTCMonth(3); //April myDate.setUTCDate(21); Alert.show(myDate.toDateString()); <-- Shows May 21, 2011
This is also broken for ANY month that has less than 31 days. So if I was to substitute 1 (feb), 5 (june), 8 (sept), or 10 (nov), it will show me the following month rather than the month I specify. If I set my system clock to April 1, the alert shows the correct date I specified which is April 21, 2011. Has anybody else experienced this kind of behavior? This is also broken if i use the non-UTC methods.
Why there are differences between AS Date and Java Date? I have a startTime field in an ActionScript class and also have a startTime in the related Java class. The time set in AS is new Date(2009,11,19,10,35,50); and then I find it has the value of 2009-12-19T10:35:50.000-0500 in the Java object.
i'm trying to calculate the difference between 2 Bitmaps.One bitmap is an external image, with only black and white.The other one is a bitmap created by AS3 and filled with red.The external image has some basis shapes on it, now in flash i want to know where these shapes are and create a movieclip out of them so i can later use it.Now what i've done is created 2 bitmaps for the image, and 1 sprite to try and make those movieclips.The thing that i have now is this:
Code: Select allthis.trackBmpd = new BitmapData(loader.width, loader.height, true); this.trackBmp = new Bitmap(this.trackBmpd); this.trackBmpd.draw(this.loader);
[code]....
But here i'm kinda stuck, i use the blendmode to see what the difference is, but how can i use this blendmode to create those movieclips out of it?
I have a datagrid wherein I only want to show users the data for the current week.I am pulling the data from a sql database and in my dataprovider which is a XMLList I have date attribute (for each row in my xmllist) which is of the format YYYY-MM-DDI want to check if this date attribute falls in the date range of the current week and then show this data.How can I calculate current weeks date range and do this.
I'm trying to find the difference (in days) between a date and the end of the year.
This code: Code: var NewYear = new Date((new Date()).getFullYear(), 11, 31); var CalcDate = new Date(); DiffInDays = Math.floor((NewYear - CalcDate)/86400000);
Is nearly right, but it seems to be a couple of days out - If I run it as at today (Feb 23rd 2011), It gives me 310 days till the end of the year, whereas (by counting on all my fingers and toes) I get 313 days.
I came accross another issue regarding the accuracy between the getTimer and date.getTime functions.I use this simple script (AS2)
[Code]...
What happens if you let this simple app running is that the trace will show that the difference between the getTimer and date.getTime results slowly increases.I would assume some inaccuracy, but not one that would slowly increase during the lifetime of the application. The reason I want to compare the two values is that I want to see if someone is tampering with the application speed with a program such as Cheat Engine. And I noticed the date.getTime function isn't affected by that program, but the getTimer function is.
Im currently building a little 3D particle engine in flash the uses sprites.to set the position of each sprite I am using the projectVector function below. (the viewTransform matrix is the particles world matrix concatenated with a perspective projection matrix)
I have two similar Objects. I want to compare them to determine if they are different data-wise (see below), and if so, display what the difference is. To complicate things, let's say the Objects are totally anonymous - I have no knowledge of their structure, contents, cannot attach listeners, etc.Comparision turned out to be easy: I'm using the classic "Serialization" approach, which comes from Java:
ActionScript Code: public function compareObject(obj1:Object,obj2:Object):Boolean { // serialize the objects var buffer1:ByteArray = new ByteArray();
[code]...
If the data in the objects is in any way different, the routine returns false... classic Byte-compare. Easy, fast, very efficient.Now here's my question: is there an easy way to determine WHAT the difference is? I'm thinking along the lines of some kind of change object or XML structure that says "This field changed value, that array got this item added, this property was removed, etc".I started playing with complex looping structure and iterators until someone pointed that some object fields/properties cannot be found via iteration.
Possible Duplicate: What is Adobe Flex? Is it just Flash II?tell me in layman's term as to whats the difference between flex and flash objects. i know that programmatically there are differences and there are difference in the extension but then why do some flex programs have a .swf extension since the extension for flex is swc ?
I created a script that will rotate a different ad every day, based on a comparison of the current date & the ads assigned day. The bug in the script is that the number of ads vs the number of days may be odd, so the last one or two ads will miss a (days) rotation every month. Is there a way I can get this to work so every ad hits its rotation.
var displayAdOne:Array=new Array; var displayAdTwo:Array=new Array; var displayAdThree:Array=new Array;
Obviously the two date objects are somehow subtly different, and that difference somehow gets overlooked when they're parsed out as strings, but how are they different?
I have a multidimensional array where the items have Date objects. I 've tried to use Array.sortOn(myDate) with no success. Do I have to convert the Date to a string (like 20070731) to use sortOn correctly?
I am trying to compile some example actionscript code. In Flex (Flash Builder 4.6) I imported a project folder (happens to be the PurePDF examples). In a few places, I have yellow "?" icons when looking at the source files - though there are no warnings or errors showing up for them yet (I do have other errors I am addressing). This is an example - when I hover the "?" icon, I see access of undefined property getTime:
[Code]....
I cleaned up the errors I mentioned, and these yellow "?" marks still appear when viewing the code. There are no warnings or errors in the 'problems' window, but these question marks I describe are still there. Even if I close the file and clean the project and re-open the file.
I as this working in AS2 and need to update to AS3...shows that AS3 doesn't like sloppy coding. Here's what I need: I pull data from an XML and that works when I put the data into a dynamic text box. However, I can't seem to get the date of birth into a variable. I have some code that calcs age in years but uses a string literal that I thought I could just replace with a variable from my XML...ain't a workin'. Here's the code I have:
I am working on an application that is near the end of its development cycle and has mostly passed user testing. We recently realized that having flex convert dates to the client's local timezone is not desired, as all of our dates are in EST and contain no time data. Since BlazeDS sends dates in UTC, this results in the dates being converted to the day before in timezones west of EST.
The best solution is to go in and refactor all dates to adjust for the timezone offset, but that is just not doable at this stage. Since all dates in our application don't care about time, I would really like to be able to intercept all Date objects that come across BlazeDS and adjust for the timezone offset.
I need to load swf according to the months. I have the script with the date, hour and days, but I need to load a swf in January, other in February.[code]...
I am sorting xmllist profilexml. In the list dates and months are sorted using SortField. It is sorting up to September month. After that Oct, Nov, and Dec are coming and displaying on the top in the datagrid.
finalList = new XMLListCollection(profileXml); var sortL:Sort = new Sort(); sortL.fields = [new SortField("startDate", true)];
[Code]....
<startDate>2/15/2011</startDate> as per my understanding it is sorting until 0-9 numeric fields only. Is there anything I need to add in this code for numeric sorting?
my understanding is that primitive types (uint, string, Number, etc.) of a class do not need to be set to null for garbage collection.
for example, i am not required to write this dispose() method in the following class:
package { //Imports import flash.display.Shape;
[Code]....
if this is true, which i believe it is, what is the difference between objects of primitive types and objects of non primitive types concerning memory allocation?
I am working with a Flex DateTimeAxis. I have a scenario where the DateTimeAxis sometimes creates duplicate months on the Axis. The month label unit is generated based on a min/max value that is supplied to the DateTimeAxis, it is NOT generated by the series data as far as I can tell. In other words, the duplication does not exist within the data supplied to the chart, but is part of automatic label generation process that DateTimeAxis will execute when supplying a min/max value for the axis.[code]...
I'm using greensock to create the tweens, but I need to be able to have the months continue their animation if I ROLL_OUT of 2008 Additionally, I need to set the timeline.reverse(); on all the months, but that doesn't seem to be working, and I think it's because I have it set to pause. is anyone familiar with tweening libraries? Can this be fixed? I tried doing timeline.duration but that just sends the animation to the end and I want it to animate to the end-not just go there.
I have a calendar-class and I want to see if there is a post in my database for any of the dates. I was thinking a nested loop, the first one loops through the dates of the month and the nested one compares variables with the date.
Ex. loadVariablesNum("[URL]", 0) for (q = 1; q <= Days; q++){ //load 'day-symbol' for(x = 1; x == 10; x++){ if(q == someArray[x]){ //someArray[] from loadVariablesNum //mark day... }}
How long would it take for a raw beginner to learn Action Script 3 coding so as to have a basic understanding and an ability to code Flash.Also to be able to take existing code and adapt it to suit ones own flash project ?Are there any training videos on such or good books to read ?What is the best way of learning AS3 ?Is it in fact best to forget AS3 and get tuition in programming or some other discipline then take a look at AS3 and what timescale would be suitable to achieve this so as to meet the goal stated above
I looked high and low for a tutorial on this and got squat! I need to make this up soon. I have it half working at the moment, i still need to make a database for the events and such. But right now I need to get the calendar scrolling threw the months when the buttons I have are clicked on. this is my code:
I've published Mac projector files and .exe file from Flash CS4 for several months without issue. For the past week when I've published Mac projector files the .app icon appears on my desktop but when I try to play the file the dock opens but the file doesn't play. Any Mac projector files I published prior to this problem play fine.I've tried creating a new .fla file and have reinstalled Flash but I'm still having the problem. EXE files and SWF files play fine. Also, the Mac projector files publish at about half the file size they did before this problem, while the EXE and SWF files are the same size.
Today is 28-05-2010, so I need to list Event 01. On 01-06-2010 I need to list Event 02. I have the basic AS3 code for listing the XML working, but I'm having trouble filtering the result.
