I have a Flex project. I want to dynamically create mx.controls.Image objects and add them to the display. However, the number of images and it properties deponds on the value stored in a database. Hence, I have to connect to the database,read the values for data table, then create objects dynamically according the values.
Then, I wonder if this is possible and how to do this.
Thanks in advance.

Just try declaring a variable as *.
Like var any:*; And check always for null. So it will take any type of value.
Hope it will help.

Populate and depopulate to show how it works. Check for empty and size of each structure and implement methods that perform preorderd, inordered and postordered traversels.
I am not sure on where to start. If anyone could do the entire code that would be greate. Thank you in advance.
I use https://codesandbox.io/s/wonderful-lichterman-br63z and would like to prefill items (with specific data) in the form.
What is the best approach to do this ? I have entries in redux which I would like to get into this dynamic form prefilled.
I know that I can create placeholders, but how can I add specific data ?
What really makes it difficult is that I need a relation between a rendered item and an entry from a data array.
Please see:

I hope the solution works for your use case. You will need to replace my hard-coded default values with desired initial values from your redux store. Cheers!
Update:
I found a better implementation. Turns out add method allows one to set a dynamic fields defaultValue

I'm looking for a way to create dynamic input fields in Meteor.js. I've chosen not to use Aldeed's Autoform for greater control over the code. From front end point of view I have no issues to add dynamic fields with +/- button to add and remove fields. What I'm struggling with is the insert statement on the back end. How can one add dynamic insert in Meteor.js? Cheers!
Essentially you need a reactive array of element that's rendered to the DOM via {{#each}} ... {{/each}}. When the array changes the DOM would re-render.
There's no need to create your own reactive array, there's one here with an example that does exactmy what you're asking for:
http://reactivearray.meteor.com/
However I'd recommend going one step further and using the ViewModel package for this (by the same author). Here's an example which shows how to use it to insert fields:

Thanks Tim, these are both pretty useful. I'm using Collection 2 so decided to use objects ('object.$'). This is easy solution for me. cheers.
This question is about implementation.
I'm building an android application with titanium.
There are multiple screens and i take data in each of them.
Each screen is a commonJS module
I want to write all the data i take to an sqlite3 database, but i suppose it would be inefficient to write them as i take inputs. Two ways come to my mind as to how to do this.
create an object and pass to each module to hold the data as i take them
create an object in the first module to hold the data and pass each data item to it by firing a custom event.
What i'm asking, is if there's a better approach to this or which of these two would be more efficient.
NB: I don't have a lot of screens, but that could change though.
Thanks.
Titanium.App.Properties are widely used for Global variable creation.
The following methods will help you to create global variable
setBool : Sets the value of a property as a Boolean data type
setDouble : Sets the value of a property as a double (double-precision, floating point) data type
setInt : Sets the value of a property as an integer data type
setList : Sets the value of a property as an array data type
setObject : Sets the value of a property as an object data type
setString : Sets the value of a property as a string data type
All the above methods will allow user to save corresponding type of data as gloabl. You may retrieve saved values using getBool, getDouble, getInt, getList, getObject, getString methods respectively.
i think Ti.App.properties set and get string would do fine for you here is example too

Ok so I have drop down list connected to a datasource, and I need to change 2 or 3 of the values before they are displayed and I'm just having trouble figuring out what to do. I'm assuming I setup some kind of loop to check the values, but thats all I can figure. Does anybody have any general suggestions or resources they know that I can look up? Thanks.
You need to do your processing before you bind the datasource. So for example, create a dataset of results or arraylist, process the results changing your values and then bind to your dataset/arraylist.
You'll need to be more specific about what you are binding to and how you want to process for me to be more specific..
