Saving and loading

is my coding correct, because i cant seem to save or load. well i dont know if it saves, but when its loading it returns null.
public void saveAttributes(String filename){
try{
FileOutputStream outputFile = new FileOutputStream(filename);
ObjectOutputStream outData = new ObjectOutputStream(outputFile);
outData.writeObject(this);
outData.flush();
outputFile.close();}
catch (Exception e){
System.out.println("Error Saving: "+e.getMessage());}
public static void loadAttributes(String filename){
try {
FileInputStream inputFile = new FileInputStream(filename);
ObjectInputStream inData = new ObjectInputStream(inputFile);
Attribute attribute = (Attribute)inData.readObject(); //not sure about this line. Attribute is the class where these and other methods are located. the load and save methods are called from another class.
catch (Exception e) {
System.out.println("Error Loading: "+e.getMessage()); }
}

this caught my eye are you trying to save a object then load it ?

Saving and Loading specific properties of an Image

Hey everyone. I'm currently in the process of developing a game which allows you to customize the color (hue) of your character via a slider. What I would like to happen is: Upon clicking either Accept or Play, it will save the current hue of the image, navigating back to that page will load what was previously saved (hue), as well as when starting the game, it will replace the standard graphic with the previously saved image.
Below is the code I have right now that pertains to the image with a basic non-functioning properly saving and loading code:
import flash.events.KeyboardEvent;
// open a local shared object called "myStuff", if there is no such object - create a new one
var savedstuff:SharedObject = SharedObject.getLocal("myStuff");
Accept.addEventListener(MouseEvent.CLICK, SaveData);
PlayBTN.addEventListener(MouseEvent.CLICK, LoadData);
function SaveData(MouseEvent){
           savedstuff.data.username = Sliders.Dino.MovieClip // changes var username in sharedobject
           savedstuff.flush(); // saves data on hard drive
function LoadData(event: MouseEvent)
           if(savedstuff.size>0){ // checks if there is something saved
           Sliders.Dino.MovieClip = savedstuff.data.username} // change field text to username variable
// if something was saved before, show it on start
if(savedstuff.size>0){
Sliders.Dino.MovieClip = savedstuff.data.username}
What I have above is only saving the actual image, which is inside a movie clip names Sliders.
Below is the Class I am using that associates with the slider that changes the hue of "Dino".
package
          import flash.display.Sprite;
          import fl.motion.AdjustColor;
          import flash.filters.ColorMatrixFilter;
          import fl.events.SliderEvent;
          public class Main extends Sprite
                    private var color:AdjustColor = new AdjustColor();
                    private var filter:ColorMatrixFilter;
                    public function Main():void
                              /* Required to create initial Matrix */
                              color.brightness = 0;
                              color.contrast = 0;
                              color.hue = 0;
                              color.saturation = 0;
                              /* Add Listeners function */
                              addListeners();
                    private final function addListeners():void
                              colorPanel.hueSL.addEventListener(SliderEvent.CHANGE, adjustHue);
                    private final function adjustHue(e:SliderEvent):void
                              color.hue = e.target.value;
                              update();
                    private final function update():void
                              filter = new ColorMatrixFilter(color.CalculateFinalFlatArray());
                              Dino.filters = [filter];
Overall what I'm asking for is: How do I get it to save the current hue of an image by clicking a button, and then having that previously saved image be loaded upon reloading or clicking a button? To me, it doesn't seem like it should be too hard, but for some reason I can not grasp it.
Thanks in advance for reading this and for any assistance you have to offer!

This is the Class that you told me to use:
package
          import flash.display.Sprite;
          import fl.motion.AdjustColor;
          import flash.filters.ColorMatrixFilter;
          import fl.events.SliderEvent;
          import flash.net.SharedObject;
          public class Main extends Sprite
                    private var color:AdjustColor = new AdjustColor();
                    private var filter:ColorMatrixFilter;
                    private var so:SharedObject;
                    public function Main():void
                              color.brightness = 0;
                              color.contrast = 0;
                              color.saturation = 0;
                              so = SharedObject.getLocal("myStuff");
                              if (so.data.hue)
                                        color.hue = so.data.hue;
                              else
                                        color.hue = 0;
                              update();
                              addListeners();
                    private final function addListeners():void
                              colorPanel.hueSL.addEventListener(SliderEvent.CHANGE, adjustHue);
                    private final function adjustHue(e:SliderEvent):void
                              color.hue = e.target.value;
                              so.data.hue = color.hue;
                              so.flush();
                              update();
                    private final function update():void
                              filter = new ColorMatrixFilter(color.CalculateFinalFlatArray());
                              Dino.filters = [filter];
And this is the FLA Code:
import flash.events.KeyboardEvent;
// open a local shared object called "myStuff", if there is no such object - create a new one
var savedstuff:SharedObject = SharedObject.getLocal("myStuff");
Accept.addEventListener(MouseEvent.CLICK, SaveData);
PlayBTN.addEventListener(MouseEvent.CLICK, LoadData);
function SaveData(MouseEvent)
          savedstuff.data.username = Sliders.Dino.MovieClip;// changes var username in sharedobject
          savedstuff.flush();
          // saves data on hard drive;
function LoadData(event: MouseEvent)
          if (savedstuff.size > 0)
          {// checks if there is something saved
                    Sliders.Dino.MovieClip = savedstuff.data.username;
          }// change field text to username variable
// if something was saved before, show it on start
if (savedstuff.size > 0)
          Sliders.Dino.MovieClip = savedstuff.data.username;

Saving and Loading variables in a .txt file (Offline)

I'm working a software we've done with Flash, but we'd want
people to be able to save the variables they selected. We need them
to be able to save the value of about 10 variables in a file on
their desktop, and then be able to load that file again.
Is it possible to do that without having to use php or stuff
like that (that's why we want to make it an offline applications so
we don't have to use php to be able to save files).
I know Actionscript looks a lot like Javascript and with
Javascript it's really easy to do, but all the saving functions are
blocked in Flash for security reasons.
If anyone knows how to do that, to simply save and load a
.txt file, please let me know. If it would be possible also to
change the .txt to whatever else it would be even better. The file
can still be opened in Notepad but at least it looks a bit more
professionnal to have our own extension. Again in Javascript or
with a .bat file it's really easy to save variables to whatever
type of file, even to non existing types, it simply creates a text
file with an unknown ending.
Thanks!

I found a page that explains in a really easy way how to
communicate with Javascript if the flash object is contained in an
html page, but I couldn't find any page explaining how it works if
it's not in an html page. On our side, before using the software
we're creating we'll convert it to a .exe. How can we call a
Javascript from that .exe since we can't incorporate the Javascript
in the container since there isn't really a container... Is there a
way to link to a Javascript (.js) that would be in the same folder
as the .exe? Or would there be a way to incorporate the Javascript
right into the .exe?
Let me know if any of you have a solution for that.
Thanks!

Saving and loading images (png) on the iPhone / iPad locally

Hi,
you might find this helpful..
Just tested how to save and load images, png in this case, locally on the i-Devices.
In addition with a SharedObject it could be used as an image cache.
Make sure you have the adobe.images.PNG encoder
https://github.com/mikechambers/as3corelib/blob/master/src/com/adobe/images/PNGEncoder.as
Not really tested, no error handling, just as a start.
Let me know, what you think...

How to speed up my saving and loading of a psd. file?

Hi.
My laptop's 1 TB hdd recently crashed and I replaced it with a 500 GB ssd and Photoshop loads now from 10-12 sec since i re installed Photoshop cc.
Unfortunately, the time it takes to save and load psd files has increased dramatically (I'm comparing it to how it was with my normal hdd). It also, sometimes freezes a bit and then after about 10 sec it unfreezes.
I have looked online for help, but have been unable to find anything that could really help me (or it just went over my head, as I am not very tech savvy).
Any help would be greatly appreciated.
If this has been discussed before, can someone please post the link for me.

The rule of thumb I follow to figure out scratch space says to figure on 50 to 100 times the size of your largest file ever multiplied by the number of files you have open. I have seen the scratch file exceed 800 GB once, an admittedly rare occurrence, but it often exceeds 200 GB when stitching large panoramas and the like.
As an example—and stressing that I'm aware that others have even more scratch space than I do—I keep two dedicated, physically separate hard drives as my primary and secondary Photoshop scratch disks and a lot of GB free on my boot drive for the OS. I also have 16 GB of RAM installed.
Additionally, if you only have a single HD, i.e. your boot drive, you'd need it to be large enough to accommodate both the swap files of the OS as well as Photoshop's scratch.

Liquify Cursor disappears when Saving and Loading Mesh (CC 2014.2.2)

Hello.
I'm using Photoshop CC 2014.2.2 for Mac on a perfectly built hackintosh (Yosemite, i7-4770K, GTX770, Intuos5 L, 32Gb RAM, 2 monitors).
The arrow cursor disappears randomly when dragged over the Save Mesh or Load Mesh dialogues. It's not that the arrow cursor disappears completely. Actually, instead of switching from liquify cursor to arrow cursor as it should, it stays a circle and I can see it behind the save/load mesh window. In order to make the arrow appear in front of the save/load mesh, I have to move it out of it, and carefully move it back in. If I drag the save/load mesh window to an area of the screen clear of the liquify filter window or to my second screen, the problem goes away.
Also, when liquifying, the cursor is a little laggy, like at a low frame rate and behind my pen. I can liquify with no problem, but I can't remember if this is the way the liquify cursor behaves now that the it is GPU accelerated.
All these problems go away if I disable "use graphics processor", but that's a no go for me. I have tried both OS X Default Graphic Driver and NVIDIA Web Driver, but it makes no difference.
Any ideas?
THANKS!

I've noticed it happens particularly when the arrow touches any of the text input fields, among other ways I haven't identified yet. The save mesh and load mesh are the only dialogs across Photoshop on which this problem happens.
Notice that the blue cursor drawn by me is where the cursor should be, and note that the liquify cursor can be seen behind the open mesh dialogue. In this case I have to draw the cursor outside of the open window, and drag it back in making sure I don't touch the search field.

Saving and loading control properties

Quick question,
Does anyone know of an "easy" way to save and load pre-defined appearences or "skins" for controls and indicators?
I had hoped LV 8.0 did this in the property explorer, but having just checked it out, it doesn't seem to.
I basically want to be able to define the appearance of indicators (XY
graphs particularly) based on calling up either ini files or otherwise.
I want to avoid writing a cumbersome cluster-based read and write
routine for each and every type of control (Split into classes of
course, but still.....)

Thanks tst
I will add the link to my labview folder. The property saver will be a useful feature and would be a great method to have added to all gi objects, like Gobject->SaveState(file) and Gobject->LoadState(File), this could be polymorphic and also include versioning information and even allow for some metadata about the object. Here you could make skins of a vi and it would save all the objects in a standard form.

Saving and loading 1D array to/from file

Hi,
i have some problems with my NI application. for the first, i have case structure with two cases: true and false.
FALSE: in this case i have a for loop with 100 samples. i catch signal from my DAQ (now just Simulate Signal) and what i want is to save it in a 1D array and at the end of the loop the COMPLETE array into one text file. Problem in my vi: just the values from the last iteration are saved.
TRUE: now i have while loop. AT THE BEGINN of the loop i need to load my array from the file and not in the middle of the loop. Why? The data from the file are needed during the loop.
thanx in advance

According to your code, what you are saving is an array of means (one from each iteration), and NOT the last iteration. If you want to keep the entire data, it would be a 2D array.
Why are you generating an entire waveform at each iteration? Shouldn't you just generate one point?

Saving and Loading a Scenario

Hi Friends,
I would like to know how a scenario will be saved in Dashboard,In the same way i want to load the saved scenario
http://businessobjects.auc.com/ESRI2008/cd/Sample_files/Xcelsius_2008_Samples/Flash%20Samples/financial_analysis_calculator.swf
Could you please explain me in details how to do it.if possible send me a sample .xlf file.
Thanks
Santhosh

Hi,
The Local Scenario will be saved as .SOL file on your local machine.
Even though if you are running it on Infoview, when ever you save a scenario of your dashboard.
It goes to C:\Documents and Settings\<user>\Application Data\Macromedia\Flash Player\macromedia.com\support\flashplayer\sys
and stores the data in a .SOL.
The file name will be selected randomly, mosty it will be in numbers.
Let me know if you need any other information.

Saving and loading vector

i made a program that drawshapes.
i would like to add features like saving the vector of shapes that has been created when a user presses the save button.
then loading those shapes when the load button is pressed.
how do i do this?
thanks for any help

You can always add different kind of objects to Collection (Vector), send them to back end and retrieve, send it back to the front end.
DO you want to save all this information in a database and retrieve them using Vector?? If this is the case then you need an identifier in the database for every Vector you create and use this ID for creating the Vector which u can send it to the front end again.

SFE2000 saving and loading configuration

I have a number of SFE2000 10/100 24 port POE switches.
They are configured and running OK. I want to be able to save the configuration and be able to load that saved configuration into another new swich in the case of a failure.
I have logged in and gone to Admin-File Management-Save Configuration. I then select the 'Backup' radio button and TFTP the configuration to my TFTP server. All works OK and I have a readable text file with the switch configuration on my TFTP server.
Now, here comes the problem.
I want to be able to restore that saved configuration on to a new switch.
I have set the new switch back to factory defaults. I go to Admin-File Management-Save Configuration. I then select the 'Upgrade' radio button and try and uploade the file into the switch.
If load to 'Running Configuration' the switch shows a status of 'Copy Finished' but says 'Copy completed with errors'
If load to 'Startup Configuration' the switch shows a status of 'Copy Failed' and says 'Copy completed with errors'
Am I missing something here???
I am guessing I should be able to load my saved Configuration back into a switch, shouldn't I??
And yes the switches are running the same firmware 3.0.0.17
Any help gratefully received. I am scratching my head here...
Alan

Hi Alan,
Thank you so much for your feedback.
When copying over TFTP, is there another error message following the described : %COPY-W-TRAP: The copy operation has failed ? I would suppose that at least a second message would be logged with the reason for the failure.
As far as the transfer of configuration files is concerned, it is always safer to make sure the FW versions of both devices are the same. As far as upgrading is concerned. Switches that use the older fw version 1.0.0.x need to be upgraded to 3.0.0.17 first using the easy upgrade utility. Switches with HW version 2 and FW version 2.x should be upgraded using the regular TFTP or HTTP method (not the easy upgrade utility). All of this can be read in the release notes for fw 3.0.0.17 and 3.0.0.18
As far as Xmodem is concerned, you make the connection to the switch using Hyperterminal, TeraTerm Pro or any other terminal emulator supporting Xmodem, when booting the switch, you can escape the boot sequence (given the switch does not boot up) by pressing Esc or Enter when this appears on the screen. You'll then have an option to "Download Software", select this option. Then on your terminal emulator, select to transfer file (send) using Xmodem. This should do the trick.
Hope this helps,
Best regards,

Saving and loading serialized objects (StreamCorruptedException)

Hello,
I am relatively new to Serialization (coming to that, a bit new to Java too) and I am having a problem with the following:
I am saving a number of serialized objects (all of the same class) in a file using the following way (the method is called multiple times to save a list of TeamMember objects):
Note: TeamMember is a custom class.
public void addTeamMember(TeamMember p) {
            outputStream = new ObjectOutputStream( new FileOutputStream( "team.dat", true ) );
            outputStream.writeObject( p );
            outputStream.flush();
            outputStream.close();
            outputStream = null;
}Then I'm trying to retrieve the objects from the file and display them. The method used is the following (it will loop through the file until found or it throws an EOFException. Is using the EOFException good practice to search through the entire file?):
public TeamMember getTeamMember(String id) {
        TeamMember currentMember = null;
        try {
            boolean found = false;
            inputStream = new ObjectInputStream( new FileInputStream( "team.dat" ) );
            while ( !found ) {
                currentMember = (TeamMember)inputStream.readObject();
                if ( currentMember.getId().equals( id ) )
                    found = true;
            } // end while
            closeInputFile();
            return currentMember;
        } // end try
        catch ( EOFException e ) { // end of file reached
            closeInputFile();
            return null;
        } // end catch
        catch ( IOException e ) {
            closeInputFile();
            System.err.println( e.getMessage() );
            return null;
        } // end catch
    }Now as a test, I am adding 3 members with IDs 1, 2 and 3 respectively. Then I am calling getTeamMember three times with the different IDs. With ID "1", it works fine. When I give it ID 2, it gives an IOException with message "StreamCorruptedException: invalid type code: AC".
While tracing the program, I've seen that it always gives me that error when reading past the first object saved in the file.
Am I saving the objects in a wrong way, or reading them is done incorrectly?
Any help is much appreciated.
I hope I was clear enough, and that I posted in the correct forum.
Thanks in advance.
Andrew.

If that is so, might you hint me for a work around?
I want to append objects in a single file, then be able to find and read an object from the file.
Thanks again.

P7N diamond bios settings listing, saving, and loading

I think I know the answer to both of these questions, but what the hell maybe the obvious isn't always the case and a yes to either would be really cool so
Is there any way to list my bios settings, you know like a simple cat or tostring() so I can have a cheat sheet
if I save my bios settings in user settings, can I load those into a new version? (I'm thinking they're erased with the new flash, it wouldn't work, or it would flash back

Allow me one last comment in this thread because I think Karlbad did not get the point of my reply:
Creating a tool to readout parts of the CMOS Memory (where the settings are stored) is not a problem. Here is the data a simple BASIC Program puts outs:
The tricky point is to relate each and every one of these numbers to their particular function within the parameters of my particular BIOS Setup structure. To translate these numbers back to the actual options in the BIOS Setup mask is a possible task. However, it takes many, many hours. This in itself is not a problem either: the crucial point is that this needs to be done for any particular BIOS Version that is looked at.
If this relational problem is considered, it easy to understand that pen&paper and/or a digital camera are better ways to get the job done. They do not take hours of programming which would need to be repeated for any particular BIOS Version. And because of that, such tools are a complete waste of time, a complete waste of energy and ambition and also a pointless activity. And (to take the arguement one step farther) that is precisely why you will not be able to find anything useful using Google. Useful tools for this kind of task don't exist, because they are pointless.
Now, if that is to hard to understand, I don't know what to say. Reacting with swearing is probably the only possible response. However, it does not rule out the fact that your memory in conjunction with a pen and a piece of paper and/or a camera is the best option here.

My 1.2 bios does have an option to save settings
Yes, but not to a file external to the BIOS and even if, you would get a similar sequence of raw data as you can see in the screenshot above.
Your best options under the bottom line:
- use your memory
- use pen & paper
- use a camera
--> Problem solved.
