I have a flex-application deployed on tomcat with blazeds. User constantly selects ranges excel-document. Now, a user enters a cell addresses in text fields (for example, C1: C20). But it is very inconvenient! How to display excel-data as a table in my application? I think, I can parse excel-document using Apach POI and transmit these data to the Flex-application. But there are other ways?

View 3 RepliesOur users want to copy and paste some rows from an Excel spreadsheet, or a chart generated in Excel, into a text box within a Flex application.It would be ok for it not to be fully functional, like an ActiveX object, embedded in the flex app. If it converted it to a static image, that would be fine. But I don't know of any Flex component that supports this.
View 1 RepliesI'm about to have to write a web page/app that will serve the agenda for circa 100 people on a page. One line per person, one column per day with 3 clickable zones in each cell. In HTML, the page is way complex for the browser to load quick and there is no possibility to click on a border between 2 cells to for example split an event that spreads among several cells. So I search an not too overkilling technology to render this kind of view. I begun with a PHP generated HTML page but the number of elements in the page make the mouse move jerky.
Moving to JAVA would give me better performances regarding the reuse of the generator of the view but it will still be an HTML page. So, here is my question: do you think that going forward with JAVA and its graphical capability is the simple solution or is Flash a better option for this part of a Web App? I'm afraid of the code I'll have to write in JAVA to handle the GUI presentation as well as the events generated by the 1000's cells plus borders of the page. In Flash, the graphical part seems simpler even if the actions handling is still huge.
I have a Flex application with a couple of DataGrids with data. I'd like to save the data to a file so that the user can keep working with them in Excel, OpenOffice or Numbers.
I'm currently writing a csv file straight off, which opens well in OpenOffice or Numbers, but not in Excel. The problem is with the Swedish characters, which turn up as other characters when opening in Excel. Converting (in Notepad++) the csv-file to ANSI encoding makes the show up correctly in Excel.
Is there any way to write ANSI-encoded files straight from Flex?
Any other options for writing a file that can be opened in Excel and OpenOffice?

I'm trying to get the title from the selecteditem from this datagrid (which is filled by a rss-feed) in a label. I've searched for ways, but I can't find how I should get this done.
This is the eventhandler I've added to the datagrid, and the function:
dgAutoFill.addEventListener(ListEvent.ITEM_CLICK, showDetails);
public function showDetails(event:ListEvent):void {
lblTitle.text = ?;
}

Is ok to access to the label in the another page, and how can i do that

I built a simple hello world app to check out the Flash Builder 4.5 mobile capabilities.Here's how it works:The Default View asks for name in an textinput and has a continue button.When you click the continue button it pushes a new view in the viewNavigator which just displays "Hello " + name in a label.When you click anywhere in this view, it pops a view (i.e. itself) from the viewNavigator, to go back to the default view
I see only 1 issue with this:When I get back to the default view, it is in its initial state, i.e. the textInput is blank. It seems as if the viewNavigator created a new view of the default view's class and pushed this, instead of just removing the top view and displaying the previous one.I see this being especially problematic for programs which display data in a grid and you can click the data to view the detail...when you get back, the grid will be empty.
EDIT:
Project name: HelloWorld
Code below:[code]....
Clicking on screen 2 gets us back to initial screen. Notice the blank textInput
I'm working on a Flex application that uses MVVM. I understand that it's recommended to have a 1-to-1 mapping between views and view-models. How then do I avoid performing the same calculations and storing the same data multiple times if it is needed in multiple views?
For example, imagine I have a program that can load project files consisting of a list of items. The main tab of my application has an export button that should only be enabled if the project is valid so I create an isExportEnabled property on the view-model for the main tab. The calculation for this involves validating the project by iterating though every item in the project and verifying some attribute on each. I have another tab which has a "Print Project Summary" button so the view-model for this tab has isPrintEnabled. The value for this flag is based on the same criteria, whether or not the project is valid.
I could put the logic for determining these values in their respective view-models, but then I end up calculating the same value twice when a project is loaded. I could move isValid to the domain model but then the model becomes denormalized. What if a saved project is edited without updating the "isValid" flag? I could make a global "Project View-Model" for the entire project which calculates whether the project is valid and then have isExportEnabled and isPrintEnabled delegate to that. However, then I end up with a hierarchy of view-models which this article recommends avoiding: Applying the Presentation Model in Flex

View 7 RepliesI have a tabbed view with in the second tab a splitview controller.
The master view shows a list. When selecting an item from that list it opens a second view with a new list by using navigator.pushView.
When I select an item in the second view/list it has to be passed to the detailview. Is there a simple solution available?
I have pretty good basic "action script" skills for developing flash files and movies, but I don't know how to do dynamic things with asp, aspx, etc. I have a local application that runs form my computer and is not connected to the internet. The application keeps track of button clicks on each buttton as separate variables. Here is my question ... each time the flash movie runs and buttons are clicked, I want to record the clicks on each button (which exist in the application at runtime) and save them to something like an excel spreadsheeet or access database. Any easy way to do this without getting into server-side stuff?
View 3 RepliesI want to create a form (flash or java/ajax) that allows selection data to be pulled from an xml file.
Example:
A ring builder application - the user selects the ring setting in one dropdown and then they select a diamond in another drop down. But the prices of the diamonds changes every day based upon the market, so we would need to easily update that data - hence an xml or excel file.
It would be even better if the data could be linked - such as selecting a princess cut diamond, then the settings that are only compatible with princess cut show up, and then after selecting a setting, only diamonds that are the right size for the setting show.
My friend and I were looking into trying to have flash (cs3 or 4 probably) communicate somehow with Excel*, I know this is a general question, but is that in any way possible?
View 3 RepliesHalf way through;user saves the answers to a CSV file to a location.then continue the test and save the 2nd part to the same location (different file name). The next person completes the same test, and theoretically saves in the same location OVERWRITING the file. HOW IT SHOULD WORK when they overwrite the file, it SHOULD add it to the next ROW in the excel (csv)document, not overwriting the WHOLE file. In the end, you would (in theory) have a number of rows in one excel document, each row, a different user who completed the test The issue is: on the MAC computer, this works (im not sure if it's because the previous developer developed it on a MAC) however when I play it or move it to windows computer; It overwrites the whole CSV file, and doesn't add it in the rows.Here is the main code (half way through) for the first save:

I'm developing a Flex front end client for a Java server application and I have a set of model classes that represent objects in my business logic and should have the same properties and exhibit the same behaviour throughout all layers. These objects
-Have form validation logic for user input
-Are displayed in various forms (lists, detail views ...) throughout the UI
-Are retrieved from and sent to the server using XML or AMF
-Are validated again on the server
-Are stored in a RDBM with tables and fields corresponding to the classes and fields
This is a very common application structure, I guess. I'm already using:
ORM for the Java backend (Eclipse persistence package)
Automatic mapping from XML to Action Script, using XML schema and the classes in mx.rpc.xml, as described here.
Now, what I'd really like to do is define the objects once (I already have them in XSD) and have tools set up class stubs for the whole chain. What can I use?
I've already heard of (but not evaluated):
XMLBeans to generate Java classes from XML Schema
Granite DS to generate AS classes from Java classes
I want to analyse if the XML I send from my client Flex to my Java using remoteObject is compressed or not. for this, I'm using Wireshark, but it can't get packets in the localhost (windows vista)

I have been working on a flex application with java, as i have used Life Cycle Data Service for communication, i wana know, is there any function of flex, where i can see the loading status in percentage, that how much record is being loaded.Problem is, if there is lengthy record, no body comes to know, whats happening with software, like in Comboboxes or Grids, users usually think it as a BUG in application, but ofcourse it is not.I need such graphical loader, which keeps on loading with proper status in percentage, until it receives all data from JAVA (SQL Server).
