Import Text File widget

dcopple — Tue, 05 Jul 2011 17:39:01 GMT

I have a text file that can be downloaded from an online database with lat/lon coordinates. I can import directly into ArcGIS explored from the online link. I would like to do the same in FLEX. Any ideas, or widgets out there that will do that?

It is quite simple.
The general process is:

1. Create an URLLoader when the app
2. add eventlistener (event.complete)
3. load(new URLRequest(URL))
4. when completed, assign the URLLoader.data to a label/textArea/whateve.text

Any direction further on this would be great, where do I put the code (widget sml?, config file). I am building my app using a text ediitor, not adobe. So not sure where to put this code. Sorry if it is a dumb question, I am sure like you say it is simple, just don't know where to add the lines of code to make it happen.

I am using Agisviewer for Flex for my development, so this may need to go into a different forum, but not sure how to move it.

thanks

You may need the flash builder or an editor that can compile.

(Assuming your editor can do that) you can write a function inside. <fx:Script></fx:Script>
Here is an example that may help:
