First off I am new to using Flex, but I have pieced this app together with help from online tutorials and information. Basically my app is like a directory of names, addresses and so forth, but I also have additional fields of "week" and "day". What I am trying to do is have a list that shows only the names of, for example Week 1 - Monday. Below is some of the code I am using to help you understand what I am trying to do.
I have an sqlite db in an application and am stuck on how to pass the data that is retrieved from the db into multiple textboxes. I can get the first selection passed into the components just fine, but my problem comes in when I try to pass a second data selection into a different textbox while keeping the data from the previous selection the same in the first textbox.Basically, the user selects a recipe and that recipe is passed into textbox 1 Then another recipe is selected and that recipe is passed into textbox 2. *The recipes are selected from a different view, if that adds anything to the problem. After being selected, the view is returned to where the textboxes are.I'm not looking for someone to code this for me, but rather on how I would do it. I should be able to do that. =)My Text Components
I have a mobile application that uses an sqlite database. I cannot seem to figure out how to access the next record when the user presses the 'next' button. My database is using 'id' as primary key with autoincrement as integer.
private function nextMoveRPart(event:EffectEvent):void { var cardNumber:int = parseInt(cardNumberLabel.text);
How does working with SQLite databases work in Flex 4.5.1 for Mobile applications,I'm looking to create a general class that I can reuse. For now I only want it to handle queries and return results or fault events.Also, I am unsure if I should be using Synchronous or Asynchronous connections for mobile devices.
I am trying to get anytihng from my SQLite to render in Flex, and I can't figure out how to display any data, even text, in Flex. What am I doing wrong?
[Code]...
I've tried a number of different components, and I can't seem to get the data to bind properly (although this code finally doesn't have the dreaded "Data binding will not be able to detect assignments to... " message, or the other dreaded "Property undefined" message).
My team is in the planning phase of a multiplatform mobile app. We're considering Adobe Air/Flex or Appcelerator Titanium instead of native development, but will eventually be needing to use an external API that is ported to iOS and Android. **(one that harnesses the device's camera)The idea would be to use platform detection and overloaded classes to determine which platform version of the API to import. Is something like this possible in either Adobe or Appcelerator? If so, would the native Objective-C or Java need to somehow be wrapped in Actionscript (if Adobe) or JavaScript (if Titanium)
I am developing a flex application for mobile devices. This application will sync customer data down from an api to the mobile device. But once on the device I plan to hold it in sqlLite DB. How can I secure this data? I know that I could hash it but I guess that that someone would be able to decompile the application and get the hash key. I am new to flex and mobile development.
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.
I'm developing a mobile AIR application using IntelliJ.
When debugging in Flash Builder there is an option to clear to application data on each (debug) launch of the ADL (see screenshot below) However, I can't find this setting in IntelliJ or some ADL parameter to force a clear on each new debug session. I was wondering if such an option exist in IntelliJ or ADL.
A little background: I'm using the PersistanceManager in the application to store some user settings and I want to be able to start the application without the saved settings from my previous run. Using this setting in Flash Builder does the trick, but I'm having no luck with IntelliJ.
A question about ItemRenderers: let's say I have an ArrayCollection that is my application data sitting inside a global object. I them populate a sparks list with this data, setting the ArrayCollection as the dataProvider.
So each ItemRenderer gets a copy of an item sitting in the array. You can override the "set data" method to set the data something more domain-specific. The problem is that the data is a copy of the original item.
Now let's say we want to add some data to the item while inside the ItemRender. For example, it could call a method on the item telling it to load some details about itself, or maybe we allow the user to modify something on the item.
Obviously, we can't do any of this if we are operating on a copy because it will be thrown away as soon as the ItemRenderer is destroyed and the original object doesn't know anything about what happened.
So what's the best practice? Should I just use the itemIndex of the renderer to pull out the original item from my global array like this:
{globalArrayCollection}.getItemAt(this.itemIndex) But it seems kind of clunky to me. Is there a best practice for dealing with this?
I am developing a mobile project in Flash builder using flex 4.5. I am very new to flex, with some background in Obj-C.urrent Setup:I am passing the text property of a text input component to a second view via navigator.pushview{view.Someview, data}public function doSomething():void{navigator.pushView(Session_View, timeInput.text);This successfully passes the text I put into the textinput to the Session_View instance and I can display that text in a label in the mxml; however, I would like to take the text passed and convert it to an integer to use in my logic.Within Action Script I have tried parseInt() function with no luck.I have also tried to assign data to a variable in actionscript with no luck.
I am working on a Flex 4.5 app tageting Android. In different views the app needs to load and display images which I have deployed as part of the app. Where do I put these images? And how do I load them? I am familiar with @Embed for images, but this doesn't seem to be the correct approach in this case. I also know how to load from the file system, but I really don't know how to include my images as part of the app for distribution.
When I move page01 to page02, I pass the same data along with it using the following code:navigator.pushView(Page02, data);How do I move to page02 with passing the next row of data (instead of the same data)? In other word, how to increment to the next row of data with pushView?
I'm trying to bring data from an sqlite database into a custom made menu. I have the menu working using an array with the code shown. But, now I would like the data to come from an sqlite database.
The code shown for the database, I have used for a previous job that pulled the data into a dataGrid. I now want that same data to put into my custom menu instead of a dataGrid. How would I change the second code to do this?
I think my main question is about the "watername_dg.addItem" in the second code below and how to change that to bring the data into my buttons.
ActionScript Code: //////////////PULLING DATA FROM AN ARRAY TO BUILD MENU////////////// var _menuArray:Array = new Array("Apples","Oranges","Pears","Grapes","Limes", "Carrots", "Peas", "Beans");
I would like to move (right or left according the current view) between 2 views when I move my finger on the mobile screen; for example with Google+ mobile application, in profil section, you can change the view just on move your finger on the screen, and the offset and the moving speed must be checked before change complete view.
It is only a "proof of concept" piece of code and it "lives" in the first frame of the timeline of the Flash IDE. What happens? When I compile my SWF (AIR for iPhone), I get this error:
In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.
The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".
what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
I am creating an application in Flex that uses an embedded SQLite database. The data in the database contains quotes and other special characters which are escaped using a backslash or ''.Before I retrieve the data and render it in a Flex text area control I want to remove the ''. Is there any function in Flex which can help me do this - some equivalent of stripslashes() in PHP?
I'm having a problem with an expression in my sql statement in SQLite for Adobe AIR basically I have this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(19,20)"; updateStmt.parameters["@status"] = args[1]; updateStmt.execute();
if I run the above code it works, updating the status when the id are 19 and 20
but if I pass the ids list as a parameter like this
sql = "UPDATE uniforms SET status=@status WHERE customerId IN(@ids)"; updateStmt.parameters["@status"] = args[1]; updateStmt.parameters["@ids"] = "19,20"; updateStmt.execute();
it gives me and error, saying could not convert text value to numeric value, which make sense because I'm passing and string but the IN expression should convert it accordingly, like it does when I pass directly the list values, why is not working the other way,
I'm making an application (web based) using flex and i have a requirment to access the SQLite database on the local system. There is no server running and i've decided to give them the link to the html file and see how that works out.
So in the root directory, there will be all required swf, html files, etc and a .db file. Can i access that database thro the flex web application ?
I have been struggling with trying to interface with SQLite and Adobe AIR. I am using the Flex 4 SDK with AIR 2.0. I modified code from a tutorial by David Tucker on InsideRIA ([URL]). I am writing in FlashDevelop (which I suppose could be my problem), and I can compile and run the app. The issue is that when I go to search the db file, I always get some error which results in the 'BREAKER' trace (ie - the 'queryError' function is called). I have tried simply running the SQL command on the db and it works fine, so there is an issue somewhere in the way Flex or AIR is handling my query (or obviously I could have made a mistake in coding).
This link: [URL] has an interesting class to do just that! Encrypt an unencrypted database: but I'm having difficulty with a few things: You can find where the author, @probertson! Now I've got the following error: Compiler Error: Error #2044: Unhandled error:. text=Error #3125: Unable to open the database
Let me start by saying the source file works, since I've been using it (and the path) in another application. The error arises in the call to attach the source db to the newly created db.
