I have a utility function that will display a filesize in an appropriate form like Windows Explorer does, i.e; convert it to nearest KB, MB, GB etc. I wanted to know if the code that i wrote is correct, and if it can be made simpler. The function that i wrote is as follows : public static function formatFileSize(bytes:int):String { if(bytes < 1024) return bytes + " bytes"; else { bytes /= 1024; if(bytes < 1024) return bytes + " Kb"; else { bytes /= 1024; if(bytes < 1024) return bytes + " Mb"; else { bytes /= 1024; if(bytes < 1024) return bytes + " Gb"; } } } return String(bytes); } While it

I'm trying to add a feature to my AIR app that can listen for (configurable) global keyboard events even when the app is minimized. Ex: CTRL-ALT-SHIFT-F12 to grab a screenshot. I can't find any way to register a keyboard hook, and listening for keyboard events only captures them when the app has focus. Suggestions? I don't think that Adobe Air programs can process keypress events unless the application is in focus. http://forums.adobe.com/thread/420446 Even this question regarding a Global handler for keypresses states that the application must be in focus. Try hooking onto the stage's

My Flex client app has got some data from the back end (RemoteObjects, BlazeDS, Spring). Client has got all the data it needs, it now needs to put some information in a CSV format and make it available for download. Using Flex 3 for this. Any ideas?

In adobe Flex datagrid height is equally to fix height . I want to make datagrid height is depend data . You can set each row of the datagrid to fit based on the contents of a particular column of that row by setting the "variableRowHeight" attribute to true on the datagrid and setting the "wordWrap" attribute to true on the dataGridColumn that will contain the variable height content. I don't quite understand your question but if you are asking how to size the DataGrid to the number of rows in the dataProvider, you can try: dataGrid.rowCount = yourCollection.length; or <mx:DataGrid rowCount="

What is the fastest way to delete one specific entry from the middle of Array() Array is large one having Strings. I dont want just to set Array[5] = null, but instead array size should be reduced by one and array[5] should have content of array[6] etc. Don't have any benchmarks to support this, but one would assume that the native Array.splice method would be the fastest... So, to remove the entry at index 5: array.splice(5, 1); If you don't care about the order of the items in the array (but just want it to get 1 shorter) you can copy the last element of the array to the index to be deleted,

I've got a flex/air app I've been working on, it uses a local sqlite database that is created on the initial application start. I've added some features to the application and in the process I had to add a new field to one of the database tables. My questions is how to I go about getting the application to create one new field that is located in a table that already exists? this is a the line that creates the table stmt.text = "CREATE TABLE IF NOT EXISTS tbl_status ("+"status_id INTEGER PRIMARY KEY AUTOINCREMENT,"+" status_status TEXT)"; And now I'd like to add a status_default field. thanks!
