Help working with File() objects

Hi,i'm sorry for my not-so-perfect English.
I'm working with java.io.File object, to use and know the contents of a folder.
But if i try to use the function list() on a folder that is the first in my hard drive (For example: C:\Test on windows, or /usr on unix), and try to get the Parent...i receive null.
This is a regoular way,in my opinion; But i have a problem: i'm working at a Java File Manager, and i'd like to LIST all my hard driver present in my computer (ie. C:,D:, E:) but i don't really know how to do...!!
On UNIX, i can resolve this problem using a list() on /mnt folder, for mounted drive...but on Windows...how can i!?
Thanks for the answers...

Hi,
Take a look at:

Script Help - Working with Files - Reading/Writing

Hey Folks,
I need help build a script that will read a text string from a specific .INI file, and then write that string to a file along with the name of the computer where the string originated from.
I plan on deploying this script to our targeted workstations with SCCM 12, so it does not need recursive abilities. We want each of the machines which run the script to write their data to a single file with a date stamp as part of the name. The data written
needs to include the unique string which follows this format "devicename=DJ########", along with the computer's name. The device name which needs to be extracted starts with DJ and is followed by an 8 digit number. It would be better if we could
use export-csv than out-file.
This is what my very inexperienced self came up with so far:
get-content 'C:\users\Public\Something\myfile.ini' | Select-String devicename=dj | out-file
\\server\folder\data.txt -append
I
found this bit of code which should allow me to set the file name to a date, but I am unsure exactly how to implement this:
$enddate = (Get-Date).tostring("yyyyMMdd")
$filename = 'C:\Documents and Settings\User\Desktop\' + $enddate + '_VMReport.doc'
$filename
The developer of a core piece of software requires all computers have a unique ID, but provides absolutely no tools or guidance for tracking this crucial information. Any input you can provide will be greatly appreciated!
Please help us fix this nightmare! Thank you in advance!

I am trying to add a step where the script grabs a list of all domain workstations and saves it to a file. This file is then used as the input for the rest of the script. There is a problem with the way the computers names are imported using this method.
Here is the script:
# Rename the existing DJNumbers.csv to yesterday's date
$date = (Get-Date).AddDays(-1)
Rename-Item -Path '\\Server\Library\DJs\DJnumbers.csv' -NewName ("DJNumbers_{0}.csv" -f (Get-Date $date -Format yyyy-MM-dd))
#Save a list of all current AD computers
Get-ADComputer -Filter * | select name | Out-File \\Server\C$\DJs\complist.csv
#Extract the DJ number for every computer in complist.csv
Get-Content '\\Server\C$\DJs\complist.csv' |
ForEach-Object {
$devicename=get-content "\\$_\C$\Users\Public\myfile.ini" | Select-String devicename=
$djnumber=$devicename -replace "devicename=","`t"
$prize=$_ += $djnumber
$prize | Out-File \\Server\Library\DJs\DJnumbers.csv -Append
The problem is that the computer names include a ton of blank spaces if I use Out-File in the line:
#Save a list of all current AD computers
Get-ADComputer -Filter * | select name | Out-File \\Server\C$\DJs\complist.csv
Error looks like this:
get-content : Cannot find path '\\CM112233
\C$\Users\Public\Software\myfile.ini' because it does
not exist.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (\\CM112233 ...ction\myfile.ini:String) [Get-Content], ItemNotFoundException

If I use Export-Csv, it puts ""'s around the computer names and that breaks it as well.
#Save a list of all current AD computers
Get-ADComputer -Filter * | select name | Export-Csv \\Server\C$\DJs\complist.csv
This is the error:

Working with File objects in AIR

This question was posted in response to the following article: http://help.adobe.com/en_US/as3/dev/WS5b3ccc516d4fbf351e63e3d118666ade46-7fe4.html

How I do it is handle dragging myself manually using a standard MouseEvent. On MOUSE_DOWN I start either pay attention to MOUSE_MOVE or startDrag(rect) on the clip and handle a drag in that manner. That's how you'd always do it before in Flash so a single Touch for something Flash itself has always supported is probably why they don't work together.
I use MOUSE_MOVE more than startDrag as you can do more sophisticated things, albeit it can be expensive so keep the calculations as simple as possible. An example of a random MOUSE_DOWN handler setup that only moves horizontal (X axis):
// hold current position in lightweight ints (whole pixels only)
var startX:int;
// weak reference listener
someObj.addEventListener(MouseEvent.MOUSE_DOWN, _handleMouseDown, false, 0, true);
function _handleMouseDown(e:Event):void
     // on initial MOUSE_DOWN, store starting value
     startX = stage.mouseX;
     // add MOUSE_MOVE and removal handler for movement
     stage.addEventListener(MouseEvent.MOUSE_MOVE, _handleMouseMove);
     stage.addEventListener(MouseEvent.MOUSE_UP, _handleRemoveMouseMove);
function _handleMouseMove(e:MouseEvent):void
     // calculate
     var delta:int = int(e.localX - startX);
     // validate value, allow to go left -2000px and up to 0px
     if ((someObj.x - delta) > -2000)
          someObj.x -= delta;
          startX = e.localX;
     else if ((someObj.x - delta) >= 0)
          someObj.x = 0;
          startX = e.localX;
function handleRemoveMouseMove(e:MouseEvent):void
     stage.removeEventListener(MouseEvent.MOUSE_MOVE, _handleMouseMove);
     stage.removeEventListener(MouseEvent.MOUSE_UP, _handleRemoveMouseMove);
     // code here once drag is complete, check position? do something?
I typed it quick so there could be a logic issue in there but there's a random handler that should allow an object to go left up to -2000px and it uses standard MouseEvent. I apply listeners for MOUSE_MOVE and MOUSE_UP to the stage to assure if the users finger gets off the object that's moving they will still stop listening. Customize as necessary but this is ultimately Flash's age old built in drag/move code.
You could also calculate a valid Rect and use startDrag() to let Flash itself handle moving the object. I often want to do more things based on the position of the drag so I like to use a loop that keeps track of the position.

Help: Working with .MOV files in FCP and forced to RENDER FOR EVERY EDIT

I'm working with .MOV files from my digital camera in Final Cut Pro and every time I make a new edit, I have to render it in order to see it in the canvas.
How do I make it so that I don't have to render every edit in order to see it?
(I've worked with files straight from a DV camera, and editing went fine. I'm assuming it has to do with the .MOV files)

DV Cameras are not the same thing as a Digital camera. Digital cameras offer video on a limited basis and it's usually highly compressed in a non-editing format such as MPEG-2 or similar. NLEs are made to work with video cameras, not still cameras which is why you're having trouble.
That's not to say you can't edit video captured with a digital camera, but you need to know how to prep it for editing. Some digital cameras shoot at odd frame rates and they all use some form of compression that is not typically used in editing. This means that you'll likely need to convert your clips to an editable format first using Compressor.

Also, use the FM that MAX has if you have to work with files on application server by replacing code in the above logic at appropriate places, like replace
cl_gui_frontend_services=>directory_list_files
with the corresponding fm
and replace cl_gui_frontend_services=>gui_upload
with OPEN DATASET...
     CLOSE DATASET...
logic.
Hope this helps..

Cannot print "working with files and folders htm

When I try to print "Working with files-and-folders" from a Google search, it only prints part of it. I have changed my destination folder to no avail. Thank you or any help, Jack Menendez

What's the best method for moving all my nonsystem related stuff over to this new driveIan has provided you with the best solution, SuperDuper.
But if you have a 250 GB external, you really ought to clone your entire system,(only about 3 GB) so you have a backup.
I keep mine with a complete clone of my internal, that way it is easy to boot from the external and run utilities like Disk Utility, TechToolPro, DiskWarrior, etc. on the internal and vice versa.
If you run into a problem with say Preferences and don't know which one is the troublemaker, just trash the whole pref folder and use the good one from the clone. Font problem, same deal. And, if diaster ever strikes, you can just boot up from your external and keep right on working - fix the internal when you have time.
That's my 2 cents anyway

Creating/Working With Nullable Objects in PowerShell - How?

Hi,
how do I create and work with Nullable objects in PowerScript.
None of the tips I found worked:
> ([System.Nullable[System.Int32]]1).GetType().Name
Int32
> ([System.Nullable[System.Int32]]$null).GetType().Name
You can't call a method on a null value expression.
> (New-Object System.Nullable[Int32] 1).GetType().Name
Int32
Any help is appreciated!

Well, nullable: yes, but Nullable: no.
this is what I get in .NET if I call GetType() on a variable of type Nullable[Int32]:
int? a = null; a.GetType();

That's quite a difference to PowerShell's:
([System.Nullable[System.Int32]]$null).GetType()
You can't call a method on an expression with value NULL.
See my point? PowerShell apparently doesn't have a notion about Nullable types. That's what I need to find out for myself: "Why?"

How does operator 'less than' work with Rectangle objects?

Just found in legacy code the following:
private var firstRect:Rectangle;
private var secondRect:Rectangle;
if (firstRect < secondRect)
// do something
How does operator 'less than' work with Rectangle objects?
Doc says that object is converted to number if it is not a String.
Rectangle is not a String, though has conversion to String.
Please help.

IME the best way to know for sure is to experiment. The docs are only one person's best understanding of how things worked on the day, which is seldom 100% accurate. I find that even with code I wrote I can't accurately say 100% of what it does until I've worked with it for a while. Keep in mind that the docs are usually written when the code is written, so never expect more than a rough idea from the docs.

I'm guessing that you are just pressing the eject button on the drive. Don't do that.
Quit the application that you are using to work with the files. Then open Windows Explorer, right-click the CD/DVD drive and click on 'Eject'.

How to work with file system in linux within a JSF app?

I use this line in my backing bean to log some events:

fhxml.setFormatter(new XMLFormatter());That works fine in windows but when I deploy it in my Tomcat 6 in linux It doesn't work. How can I work with file system in linux?

You should never use relative paths to access the filesystem. The path would be relative to the current working directory which is not per se the same in all environments. To convert a relative web path to an absolute file system path, you need ServletContext#getRealPath(). Use this absolute file system path in the java.io stuff. In a JSF application on top of Servlet API you can get the underlying ServletContext by ExternalContext#getContext().
Alternatively, if the file is located in one of the default paths of the classpath or if its path is added to the classpath, you can also just use ExternalContext#getResource() or even #getResourceAsStream() using just the file name.

WF error: There are no workflows that have already worked with this object

Hello all,
I am getting the error "There are no workflows that have already worked with this object" when I go to IQS23--> enter notification number --> workflow overview. I tried to find information related to this error message but could not find anything. If anyone happen to know anything about this error, please let me know.
Thanks.
Mithun

Hello,
As the error message says, it can't find any workflows that have dealt with the instance of the object you're inquiring about.
If you know this isn't true, or if you don't know what object this concerns, the you could try debug to see which object is being searched for.

Managing spaces when working with files

Hi, how can I work with files on windows on paths thats have blank spaces like "Documents and Settings", I used getResource().getFile() and writting the path but it always fails!
The FileOutputStream always thorws the exception FIleNotFoundException.
I tried the path with blank spaces and tried with %20 but always is the same.

Are you saying that OutputStream os = new FileOutputStream("C:/Documents
and
