Serializing Vectors that are in other classes

If I have...
public MyPanel extends Jpanel implements serializable
private vector d;
public MyPanel()
d=new Vector();
public void paint comp(gra g)//etc
Part f=(part)d.get(i);//etc
d.draw(g)
and i OutputStream.write(MyPanel); and InputStream.read(MYpanel) is the vector serialized as well?(Yes the objects "(Part)"within the vector are/is serializable) because when i do:
MyPanel g=(MyPanel)in.readObject();
and then MyFrame.setMyPanel(g);
the vector becomes empty!! and the parts in the vector can no longer be drawn;
help?
dev

I am not sure what the problem is, but,
- The vector class is Serializable (it isn't the spelling (capital 's') is it??).
OR
- Should it be JPanel g=(MyPanel)in.readObject();
OR
- How do you actually get the vector as there is no accessor method and the vector is private? Could it be you are just not getting the vector because of this.
Please ignore this if I am talking rubbish (it is late).

I have a DLL written in VC++ using MFC exteintion DLL.

You can create a wrapper dll from which you can call your dlls functions.
Guidelines on how to create a dll that can communicate with LabVIEW are provided in the document "Using External Code in LabVIEW", which should be included with LabVIEW. You can download the document also from www.ni.com at:

HT2515 Does iChat work with other users that are on other types of smartphones? or only Mac phones and Mac mail, contacts, etc?

Does iChat work with other users that are on other types of smartphones? or only Mac iPhones and iMac Mail, Contacts, etc?

Hi,
The Messages Beta will Send iMessage to iPhones (Messages replaces iChat)
iChat can SMS to phones
It needs the computer to be listed as if it in the United States and contacting a Phone that is on a Carrier in the United States that is accepting SMS forwarding from AIM
You list the Buddy as AIM and then +plus their number as in +123456789
The computer can be made to "think" it is in the United States in System Preferences > International (or Text a Language in Lion) then Formats tab.
The Phone has to be a US phone with all the trimmings about AIM's SMS forwarding.

Could you (in the next verions of firefox), include a Warning Box, for people deleting "recently bookmarked". It does not tell you that your systematicallly deleting bookmarks that are in other folders.

You should change firefox, or at least have a warning box when deleting "recently bookmarked". I decided to clear that folder out, and then when I went to use a bookmark.. I didn't have any bookmarks in ANY FOLDER at all. I did manage to restore the booksmarks, but easier to just warm people, or just let them clear out the recently bookmarked. It had bookmarks from over a year ago that I had deleted in other folders, but still manage to hang out in the "recently bookmarked" folder. Oh, and if I delete a bookmark in a folder, please have it delete the bookmark in the "recently bookmarked" also.
== This happened ==
Just once or twice
== Cleaning up my bookmarks

"Recently Bookmarked" is a so called [[Smart Bookmarks folders|Smart Bookmark]] that shows the result of a place query in a list.
"Most Visited" and "Recently Bookmarked" are examples of the so called [[Smart Bookmarks folders]] and are not real existing folders.
Such smart folders show a list created by a query of the places.sqlite database that stores the bookmarks and the history in Firefox 3.
The bookmarks that show up in such smart folder listing are stored elsewhere in another folder and any changes made are applied to the real bookmark or history item.
Such lists show a maximum of 10 entries by default and you add a new bookmark or visit a website then a new item is added at the top and the entry at the bottom disappears from that list.
The items that are removed from the list are not gone, but merely do not show up anymore in that list.
Any actions like copy & paste or delete that you perform on bookmarks in such a list are done on the original bookmark.
If you do not want a specific list then remove that query (right-click: Delete), but do not delete the content that is displayed in such a list.

How to attatchment some files that are in other server to send an email?

Hi
I need to send an enmail with sql, but i have to attatchment some files, those files are in anohter server, so I want to know, how attatchment those files?
Thanks in advance

Yeah, I don't know if you can attach a file on a remote server. Why not just copy it over to the SQL Server machine, and attach it form there (which would be the local machine when the file is downloaded).
Please see this for info about using email in SQL Server.

Can I read/write global variables that are in other PC?

I attach the vis and the executables.
My problem is that when I run( continuosly, because in other way, I read the default value of the variable) getvalue.vi and setvalue.vi, I don´t have any problem, I can read/write the global variables, the two vis is running in the same PC.
But when I do the exe and I run them continuosly , it doesn´t work.
Any solution?
Thanks in advanced!

Hello Bichillo,
By running the vis continuously you are running into race conditions. If you cannot control when you are writing to or reading from a global variable, you cannot know whether the value writen/read is the right one or not.
In your case the global variable value that is read is sometimes the last value writen and sometimes an empty string.
To make the global variable behave as desired, that is, keeping its last value, the global variable must be in memory when you access it using VI Server. If it is not in memory, the returned value is an empty string. That´s why you sometimes get a non-empty string: when you access the global variable to read its value, it happens to be in memory because you´ve just writen to it.
To ensure that the global
variable is always in memory and it keeps its last value, you must include the global variable into your block diagram. I am attaching modified vis that implement this.
Hope it helps.

Propagate application exceptions that are in other jar.

Hello:
I am trying to deploy an application (call APP-ONE)which has an "applicacion exception" (call App-exp), this extends from another "cross application exception" (call cross-app-exp), and it is on CROSS-APP-EXP.jar.
The example is:
APP-ONE.jar
delegate.java
class delegate throws App-exp {
ejb.clase();
ejb.java
interface ejb extends remote {
public void clase() throws App-exp, RemoteException
CROSS-APP-EXP.jar
Cross-app-exp.java
class cross-app-exp extends RemoteException
Then, my APP-ONE has APP-INF/lib/CROSS-APP-EXP.jar
When I execute ANT it generates APP-ONE.ear with APP-INF/lib/CROSS-APP-EXP.jar (and other things). When I deployed this, the server launch me the following exception:
<04-03-2005 01:17:33 PM VET> <Error> <Deployer> <BEA-149201> <Failed to complete the deployment task with ID 0 for the application newMakeAnt.

¿Where must I put the CROSS-APP-EXP.jar for weblogic server reads that in deploy time?
Please I need some help.
Thanks a lot.

Bumper type cases that are available other than Apple's brand...

Are there anymore out there...i do like the Apple Bumper...also there is the SGP Hybrid Neo Ex case, looks the same but different feature...any one teied this by any chsnce...what other alternatives are there aside from these two?

I got the free black Apple bumper when they first started shipping them. I can't definitely say if I get better performance with or without a bumper. However, I can definitely say that I'm not getting any scratches under the bumper(s). The reason I made bumper plural is that I bought the "lime green" Apple one after using the black one for about a month.
The reason I switched is because the IP is SO much easier to see when it's laying around waiting for me to pick it up. The black model just fades into the background and is NOT easy to spot when I'm in a hurry and want to get out the door.
Also, I've dropped the IP a couple of times since I "bumpered" it and no nicks or other damage occurred. Whether I would have the results without a bumper, I can't say.
My previous IP's (3G and 3G S) all got scratches on the back using cases. I suspect sand/dirt gets under the cases and acts like sandpaper when the case is rubbed.

I'm trying to write an email and import files that are in other emails I've been sent. Some are attachments. How can I do this?

Hello,
I'm new to the mac world and would like to know how to compose an email including information from emails I've received. I want to forward the contents of three emails to my a new email I'm composing. One email has attachments and the others have typed info. I know I can copy/paste but I'm not sure about the attachments. Is it best to open them and copy them to the email?

Save those attachments > Default location is the Downloads Folder.
Then re-attach to your new email.

Need some help archiving and photos that are in multiple collections.

After creating a new catalog for photos from a collection, I'd want to remove the photos from Lightroom and keep on disk. In the collection, there are some photos that are in multiple other collections and I'd want to keep those images in their other collections and so not removed them from Lightroom.
Need some advice on how to easily identlfy those images that are in other collections and thus might not want to remove those images from Lightroom.

Well, Bob, that works, but agreeing with Geoff, I don't think this is the best solution to the problem; in fact I don't even think this is a good solution to this problem.
If there isn't a lot of space left, and the user wants to do something about the photos in those collections, then the photos should be moved (in Lightroom, or via this process: http://www.computer-darkroom.com/lr2_find_folder/find-folder.htm) to a different drive. This generates more free space on the SSD drive. The photos remain in the Lightroom catalog, and they remain in the multiple collections that they are in now.
MrhoniKeith -- your photos probably should not go on the SSD in the first place. Photos ought to be stored on a normal hard drive, not an SSD. You can move them to a regular hard drive en masse, freeing up plenty of space on the SSD via this method: http://www.computer-darkroom.com/lr2_find_folder/find-folder.htm. This is the BEST solution to your problem -- keep everything in a single catalog, with photos on a normal hard disk. The idea of having multiple catalogs to help free up space on one drive works opposite to the best practices of using Lightroom, in which most people recommend using a single catalog for all of your photos, except in special cases where the photo's contents are completely non-overlapping, for example Personal and Business catalogs.
Removing photos from some collections but not others will NOT free up space. That's not how Lightroom works. Lightroom has not made multiple copies of your photos for each collection. Deleting photos from collections will NOT free up space.

Javac = "cannot find symbol" when compiling class referencing other classes

I have several Java files in a directory which is declared as a package at the start of the files
package filemanager;
This program works perfectly in an IDE, however I'm having problems with compiling in command line.
I have set the classpath as I understand to be right for my computer to:
C:\Program Files\Java\jdk1.6.0_02\bin
I can compile a class that references no other classes in this package/directory.
However files which reference other classes bring up such errors:
javac AllFiles.javaAllFiles.java:174: cannot find symbol
symbol : variable Bob
location : class filesmanager.AllFiles
Bob.getItem(itemRef);
Where Bob is an example of another class. Even though I can say, compile Bob on it's own as it doesnt have any such reference.
I've tried:
javac -cp "C:\Program Files\Java\jdk1.6.0_02\bin" AllFiles.javaThis also failed.
Any ideas?
Edited by: ajr87 on Feb 8, 2008 10:26 AM

Serializing classes that contain other classes

Hi all,
Hoping someone can answer me a quick question, I'm familiar enough with Java + OO in general but just starting to try to put a multiplayer game framework together so running into a few areas I haven't encountered before... so sorry if this is a bit of a newbie sounding question...
I have a serializable class that contains a reference to another serializable class, very similar to:
public class ClassA implements Serializable
    private ClassB b;
    ...and some other fields...
    public ClassA ()
        super ();
    ...and a standard public getB and setB
public class ClassB implements Serializable
    int someValue;
    ...standard no arguments constructor...
    ...standard getSomeValue and setSomeValue...
}Now that all works fine, serializes fine, send it down an ObjectOutputStream down a network socket, deserializes the other end, all no problem. What I don't like is that to create a ClassA I have to do:
ClassA myClassA = new ClassA ();
myClassA.setB (new ClassB ());   <--- this line
myClassA.getB ().setSomeValue (5);because it could easily be ommitted (especially since the real situation is more complex that two simple classes like above) and I'll get a NullPointerException. Normally (in a non-serialized ClassA) I'd have put b = new ClassB (); in the constructor.
However I don't like the idea of doing that because when deserializing a ClassA, I imagine the deserialization mechanism creates its own ClassB object to set into ClassA? And so if in the ClassA constructor, I create my own ClassB, then the deserialization will then immediately go and create its own ClassB and the ClassB I created will go to the garbage collector, i.e. it was a pointless object to create?
Just wondering what suggestions anyone has on this, there must be a standard approach to deal with this?
Thanks very much,
Nigel.

Allthough you give a lot of information I do not quite understand what you mean, but maybe a little re-arrangement of the setB en getB methods will do it:
public ClassB getB() {
    if(b == null) {
        setB(new ClassB());
    return b;
public void setB(ClassB b) {
    this.b = b;
}

I am trying to install Lightroom and I am OK until it asks for a serial number. I purchased Lightroom from B&H and the have entered the seal number on the the B&H invoice. Nothing happens, not all the entry boxes are filled with the serial number that was provided by B&H. I looked for a serial number on and in the box it came in, nada. Need a bit of help here, what can I do?

Only the old fashioned way, like if you lost a wallet or purse.
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up.
- You can also wipe/erase the iPod and have the iPod play a sound via iCloud.
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it unless you had iOS 7 on the device. With iOS 7, one has to enter the Apple ID and password to restore the device.
