Sql :: Flex 4: Binding Label To Dataprovider (SQLite)?

Feb 4, 2011

Let me start off by saying this is my first Flex project, so I've been reading a lot, learning a lot, but am still struggling to make this work. I am trying to display records from an SQLite database within my Flex mobile application. I have the input form saving data correctly to the database, and I have a datagrid that is outputting the records (so I can confirm everything looks good). However, my problem is making the data readable.

I want the user to be able to select an identifier from either a drop down or a list (even if it's just a 1 column datagrid), and have the labels to the right update to reflect that information.

I have a flex datagrid. it is bound to an array collection. if the user sorts on column X it works fine. then, if the user causes the array collection to change, the datagrid forgets that it was sorted on column X.what do I need to do to preserve this sort preference so that the new array data will appear sorted by column X?

Data Binding - Flex Additional Label In ButtonBarButton?

Dec 5, 2011

I'm trying to extend ButtonBarButton to include an additional label that shows the number of updates for the respective box in a viewstack (which is the tabbar's dataProvider).

I can get the additional label (named indicatorLabel) to read an initial value from data, but I can't get it to update automatically like the actual "label" attribute. My understanding was that you could bind to the data object, but that doesn't appear to be the case.

Flex :: AIR SQLite IN Expression Not Working?

Mar 14, 2010

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,

Flex :: Querying SQLite Database With AIR App

Dec 13, 2010

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).

Flex :: When Does Executing Return False In SQLite

Sep 7, 2009

I've read the flex language reference: [URL]. This property is true if execute() has been called and not all of the results have been returned from the database. However, I'm having trouble understanding what that means exactly. I keep receiving an error:
Error #3106: Property cannot be changed while SQLStatement.executing is true.

I've tried creating an event handler for SQLEvent.RESULT, my thinking was that's how the results would get returned from the database and therefore executing() would return false - didn't work. Does this mean i'm trying to change my SQLStatement variable too quickly? how long does the execute() function take?

The code in question:
private function fileProgress(p_evt:ProgressEvent):void {
var char:String;
var line:String = "";
var counter:int = 1;
sqlStatement = new SQLStatement();
[Code] ....

Stream is a filestream. I'm trying to read a textfile and put every line into a new sqlite table row. I've also tried using sqlStatement.parameters as an alternative way to do my insert queries, but to no luck. that throws a different error:
Error #3110: Operation cannot be performed while SQLStatement.executing is true.

Database :: Sqlite And Flex - Insert Into If Not Exists?

Feb 4, 2010

I'm using flex to develop my first desktop app and I'm working with sqlite for the first time as well. I'm creating my database and all the tables and I would also like to add a few rows of data into a couple of the tables so that the users have some data to work with on first install.

The only problem I'm having is every time I run the program it keeps inserting the same data over and over again. I'm just wondering if its possible to do a - INSERT INTO IF NOT EXISTS. or some other kind of work around.

Flex :: Improve The Performance Of The SQLite Database?

Apr 26, 2011

Background: I am using SQLite database in my flex application. Size of the database is 4 MB and have 5 tables which are

table 1 have 2500 records
table 2 have 8700 records
table 3 have 3000 records
table 4 have 5000 records
table 5 have 2000 records.

Problem: Whenever I run a select query on any table, it takes around (approx 50 seconds) to fetch data from database tables. This has made the application quite slow and unresponsive while it fetches the data from the table.

How can i improve the performance of the SQLite database so that the time taken to fetch the data from the tables is reduced?

Flex :: Display Images From Sqlite Into Datagrid?

The retrieval of information from the database works, but I cannot quite "see" how to connect the decoded result from the database to the datagrid, to display the images.

Flex Local SQLite BLOB Display?

Jul 29, 2011

I've got 3 columns in an SQLite db I built with Firefox's handy SQLite Manager. So, I created 3 columns, an index/reference that's just an incrementing INTEGER for easy reference, a descriptive title of the image (so it can be searchable later) in a TEXT, and a BLOB type that holds the pngs.

I'm trying to add this in an assets folder into my project (as a pre-populated database) and display the blob images, one at a time, in a window one after the other, scrollable by user. This is where I'm running into problems. Eventually I want to be able to encrypt it and add a search tool, but first things first, and that's displaying an image.

I have spent several hours scouring the web about this topic, but there isn't much help out there: Adobe has tips about using SQLite with AS3 (their reference documents and the support section of their website have some overview articles) but nothing refers to reading blob data in depth.

On this site, I've found some references to Adobe Air looking for extra byte information when reading blobs since they have a different syntax to write to the databases created within the program. See: What is the first bytes in a Blob column SQlite Adobe AIR? Blob Sizeinfo?
