I am developing an application in flex in which I need to calculate checksum of different files. I would like to know if there is a direct method in actionscript to calculate that or do I have to go for any external libraries?
View 2 RepliesI'm using a combination of Paul Duncans php ZipStream [url]...
Works fine in Air, but when running Flex in browser, the zip needs to include a Adler32 checksum in the header for FZip to be read.
How can I calculate an Adler32 checksum for the zip in php?[code]...
I have dynamic text boxes that populate a number from an external .txt like this:

What I need to do is divide the Net by the Gross and display the % in another dynamic text box with the variable retention . So it should display 53% or 54% if rounded up, in this case. Don't laugh at me, but this is what I've tried so far ..

I have this datagrid which has columns with a NumericStepper as an itemEditor where the user can change the number of items he wants to buy. How can I calculate the sum of all cells when the user updates datagrid's values?
EDIT 1
My datagrid is about colors and sizes of a product. The columns are generated dynamically from this function
private function getColumn(dataField:String, headerText:String,editable:Boolean) : DataGridColumn
{
var column:DataGridColumn = new DataGridColumn(dataField);
[Code]....
the row.size28 is generated dynamically. So it could be row.size29,row.size30 etc.
How can I loop through all my cells without knowing their data.property?
I have many dropdowns in my flex application. Now I want to set rowCount property so that as many rows as possible so there is less scrolling when see the dropdown items.The flex application was running on a popup window. So I think I have to know the distance from dropdown to bottom border of window, and then calculate what number should be for the rowCount. Like Height/per row height.As I known, the dropdown.y is the relative y coordinate of itself. But my dropdown has many parent UI layout component, and also I have many dropdowns, it is hard to calculate one by one.
View 1 RepliesI am building a scheduling system. The current system is just using excel, and they type in times like 9:3-5 (meaning 9:30am-5pm). I haven't set up the format for how these times are going to be stored yet, I think I may have to use military time in order to be able to calculate the hours, but I would like to avoid that if possible. But basically I need to be able to figure out how to calculate the hours. for example 9:3-5 would be (7.5 hours). I am open to different ways of storing the times as well. I just need to be able to display it in an easy way for the user to understand and be able to calculate how many hours it is.

I am working on an Adobe AIR (2.0) application that contains a feature to allow users to print documents (such as salary slips). Those documents are originally in PDF format. Due to circumstances we cannot directly display those PDFs in the AIR application (for example using flash.html.HTMLLoader). Therefore we convert the PDFs to SWFs (using the pdf2swf tool, see The SWFs are loaded into the application using a mx.controls.SWFLoader, like so:

I work on a Flex application that creates compressed files and uploads them on a server. The files are created with ByteArray.compress method, which is zlib compression. I can decompress them using Python API on the server but I prefer to keep the files compressed there. I want to be able to download and decompress the files later, however WinZip and WinRar fail to decompress them. When I google for zlib utility, I only find zlib dll library. I need a simple application for Windows (and/or Linux)
View 1 RepliesI can use Maven with FlexMojos to generate swf file, but because I have several mxml files need to build, could I build them in 1 Maven pom file?I know if I separate them into several projects, Maven can build them. But because these mxml files have some shared functions, it's not easy to manage if I separate them.Another question is the size of swf file. The original file size build by Flex builder is about 80KB, but the file size by Maven is about 800KB. Is it normal?

I'm working on a game which will involve space battles, and automated turrets. The turrets are giving me the headache right now. Here's what I got so far.
[URL]
The problem is, that the turrets aim at the center of their target, instead of aiming in front of their target to compensate for their movement. I can't seem to crack the equations needed to get the right rotation, for the turret to fire from. The data the turret has avaible, or that I could easily make avaible to it, are:
- The distance to the target (and it's x and y components)
- The current speed vector (the size and rotation)
- The angle between the heading of the target and the turret's location
- The speed of the turret's shot (fixed speed)

I'm basically trying to emulate Photoshop's Vanishing Point tool where you can define the 4 2D points and the 3D plane is calculated from that information, in terms of the rotation of the plane relative to x y and z axes.
So if you have an image like this one:
And you define the points of the four corners, maybe like this:
It would define the 3D plane that the surface must live on relative to the x y and z axes. Researching this has led me to some tutorials on drawTriangles and Homographies, but they all seem to be focused on mapping bitmap data and I can't seem to find anything that defines a 3D plane itself.
