Unsafe Operation error/Local preview

Hello,
I am using a Flash extension (Slideshow Pro) to put together
a slideshow. Just upgraded to CS3 from StudioMX 2004. I'm using the
newest version of the extension to create new SWF files but getting
the "Flash has stopped a potentially unsafe operation" error when I
try to preview them locally in HTML.
I have been to the security setting manager several times,
allowed individual links as well as the directory I am working in,
they appear in the "allow" list as they should, however I still get
the same error (yes, I've re-published and re-started everything) I
understand that this error is related to older security settings,
but why am I getting it with newly-created files?
If it matters at all the image manager I am using is
Slideshow Pro Director, which resides in my root directory and
provides xml feeds for the slideshows.
Thanks in advance for helping an amateur out! Molly

Welcome to our community
You see this dialog because of Flash Player security. When you run your project from the local C drive, you are in very unsafe territory from the perspective of the Flash Player. Flash Player then blocks certain actions until you specifically configure it to say the folder where you are running the SWF is "Safe".
These restrictions aren't imposed if you place the content on a web server, as the web page is automatically in the "safe" zone. So once you upload to a web server, you have no concerns. Your end users will not see the message you are seeing.

SWF export error unsafe operation

Hi, i am new to cs5 but when i am exporting from indesign to SWF or Interactive PDF an error comes :Adobe Flash Player has stopped a potentially unsafe operation etc etc.
when I am linking out to a URL or File on my local server.
The links work in the 'Preview and so I know they are all good.
Can anyone help. I have tried the Flash Global security settings and adding URLs etc ....this does make a difference?
Is there a setting some where that I need to unchesk to allow the links to be recognised once exported?
Desperate and all that!
Any ideas much appreciated.

Welcome to the forum.
Unfortunately, you have posted to the PrElements forum. PrE is a consumer-level video editing program.
You want to post to the InDesign Forurm instead.
Good luck,

Why this error display "Adobe Flash Player has stopped potentially unsafe operation"

why this error display "Adobe Flash Player has stopped potentially unsafe operation"
In message box following message display:
The following local application on your computer or network: null
is trying to communicate with this internet-enabled location : www.ajaxcdn.org

I get the same message and I already have the latest version (20.0.1) installed. Any other suggestions? Please and thank you!

Flash has stopped a potentially unsafe operation (all files are local)

We trying to run a small flash movie locally from a local html with some javascripts to communicate to and from the flash movie and it worked fine
however sometime late last year we started seing this message pop up. So it must been some changes in flash and/or in the browsers.
Running IE9 in compaility mode allows the flashmovie to work correctly.
Now we want this to work on Mac as well and I can't get Safari to avoid this.
Main problem is that for whatever reason Flash thinks the local html file is internet-enabled. The error box is not saying a link to an internet site, just like this:
Adobe Flash Player has stopped a potentially unsafe operation.
The following local application on your computer or network:
C:\location\file.swf
is trying to communicate with this Internet-enabled location:
C:\location\file.html
Why can't we no longer run flash movies locally like this. There is no interaction with internet in any of the files.
How do we fix it, having the users add the directory in Trusted locations in Flash Global Settings is not a good way.

either adjust your security settings: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.htm l
or, test online.

Error - Unchecked or unsafe operations

import java.io.*;

      public Dictionary()

   Gets the following error
Note: Dictionary.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
Any ideas ?

Ah, I'm getting soft: do this:
import java.util.*;
public class Dictionary {
    Hashtable<Integer, Integer> Dictionary = new Hashtable<Integer, Integer>();
    public Dictionary() {
        for(int i=0; i < 256; i++)
          Dictionary.put(new Integer(i), new Integer(i));

Error error adobe flash player has stopped a potentially unsafe operation

Dear Sir,
This is regarding the error which i am getting when i open
one perticuler adobe application
"error adobe flash player has stopped a potentially unsafe
operation "
I got one cisco flash presentation i am not able to open the
file because of this error. It would be really helpfull for me if
you could guide how to solve this problem.Awaiting your reply.I
would appreciate your earleast reply
Regards
Lijesh.

I'm getting the same problem. No explaination of why, and
downgrading all my security to DANGEROUSLY unsafe levels doesn't
help, nor does setting anything in the settings app. (Have you ever
used a slower application?)
I did find (using a Google search) a blog that pointed me to
the article located at this address:
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=13530cdd
I don't know yet if it will help, but it appears to be on the
right track.
Good luck.

Unknown compile error: Unsafe operations???

When i try to compile some of my code, i get this error :c:\File.\etc............... uses unchecked or unsafe operations.

Adobe Flash Player stopped a potentially unsafe operation

Does anyone know what this is about: a popup appeared which
said:
Adobe Flash Player stopped a potentially unsafe operation
The following local application on your computer or network:
javascript:parent.payload1018
is trying to communicate with the Internet-enabled location:
msn.server-sys.com
It then goes on to advise that if I want to allow the
communication I should click on Settings.
This sounds like a virus problem. Can anyone advise me on
this?
Thanks in advance.

Thanks for responding Gary. Pretty funny about the Google
comment - never occurred to me. Anyway I have spent the last 2 days
running many of the online scanners - Kapersky, Symantec, Macafee,
(currently running Nod32) and some malware software: Adaware,
SuperAnitSpyware, and some rootkit detectors and those are the ones
I can remember! Issues were found (some known, some not) and 2
items pointed out were actually installed by me but did not do any
damage (I looked at the registry and other places for telltale
signs of virus deployment as per Symantec instructions for those
flagged virus's but I was ok) however not one of the flagged items
explains the javascript warning. So far my computer has been on for
more than 24 hours and I have not seen any messages appear
(Javascript or otherwise) - especially since I cleaned out my
restore points. It looks like my installed antivirus software
(TrendMicro) worked for the regular virus problems and somehow
Adobe caught the javascript issue. I guess I just have to hope
there is nothing going on that is getting past them. This is what I
get for being a little risky lately. My antivirus and firewall
software are on high alert mode for the time being and we'll see
what happens from here. I take a look at the software you
suggested. If you find anything else out about the javascript error
let me know.
Thanks.

Warning "unchecked or unsafe operations" when use Vector

Can any one tell me why i get "unchecked or unsafe operations " warning.
What I want to do is return 2 vector from the first method but i figure out by making it as object array would make thing easier for me. Then i try to use it on the second method and it give me error. The program still run fine but I just want to know what happen and what the affect of keeping it?
   public static Object[] chessPosition()
        Vector <Component> blackLocation = new Vector <Component> ();
        Vector <Component> whiteLocation = new Vector <Component> ();
         for(int y = 0; y < 8; y++)
             for(int x = 0; x < 8; x++)
                 Component c = ChessBoard.board.findComponentAt(x*75, y*75);
                 if(c instanceof JLabel)
                     if(c.getName().startsWith("white"))
                         whiteLocation.add(c);
                     if(c.getName().startsWith("black"))
                         blackLocation.add(c);
        Object [] a = new Object[2];
        a[0] = blackLocation;
        a[1] = whiteLocation;
        return a;
    public static void blackPotential()
        Object[] a = chessPosition();
        Vector <Component> blacks = (Vector <Component>)a[0];
    }Thanks in advance

Lest I make a jackhole of myself:
        Object[] a = chessPosition();
        Vector<Component> blacks = (Vector<Component>) a[0]; You're casting objects to a vector of Components.
Try this on for size:
    public static Vector<Vector<Component>> chessPosition()
        Vector<Component> blackLocation = new Vector<Component>();
        Vector<Component> whiteLocation = new Vector<Component>();
        for (int y = 0; y < 8; y++)
            for (int x = 0; x < 8; x++)
                Component c = ChessBoard.board.findComponentAt(x * 75, y * 75);
                if (c instanceof JLabel)
                    if (c.getName().startsWith("white"))
                        whiteLocation.add(c);
                    if (c.getName().startsWith("black"))
                        blackLocation.add(c);
        Vector<Vector<Component>> v = new Vector<Vector<Component>>();
        v.add(blackLocation);
        v.add(whiteLocation);
        return v;
    public static void blackPotential()
        Vector<Vector<Component>> a = chessPosition();
        Vector<Component> blacks = (Vector<Component>) a.get(1);

}}When i compile this it says PortChooser.java uses unchecked or unsafe operation
recompile with -Xlint(any one know what this is?)
Is it the JDK version i'm using ? First i thought it's a security issue.As in windows is not letting me access the serial ports.
I checked with device manager.My serial ports are open. Ichanged my BIOS settings as well..
(I read inputs from parallel port.But i dont use the comm api for that)
I have installed the rxtx gnu.io package as well..
Tried import gnu.io.* instead of javax.comm.*; still the same compilatiion error!!!
Thanks in advance
goodnews:-(

It is basically a warning (not an error) that the compiler gives you to let you know that you are using a raw type where Java now supports generic types.
For example, in the code you use:
HashMap where you can use HashMap<String,String> to let the compiler know that you intend inserting Strings for both the key and the value. The former is considered to be unsafe because the compiler cannot control what is inserted into the HashMap while in the latter case it can ensure that only Strings are used for both keys and values.
The compiler is also letting you know that if you want to see the details of these "unsafe" operations you can use the -Xlint:unchecked option when compiling and the compiler will show you exactly which lines contain the code that is generating the warning. So to compile with this option you would use javac -Xlint:unchecked ClassToCompile.

Unchecked or unsafe operations

I am trying to compile code and I am receiving the error message unchecked or unsafe operations. I tried compiling it with the -Xlint:unchecked and it pointed towards a portion on the code I placed below. The code is too long to put the whole thing in here.
private Vector getNextRow( ResultSet rs,
ResultSetMetaData rsmd ) throws SQLException
Vector currentRow = new Vector();
for ( int i = 1; i <= rsmd.getColumnCount(); ++i )
switch( rsmd.getColumnType( i ) ) {
case Types.VARCHAR:
case Types.LONGVARCHAR:
currentRow.addElement( rs.getString( i ) );
break;
case Types.INTEGER:
currentRow.addElement( new Long( rs.getLong( i ) ) );
break;
case Types.REAL:
currentRow.addElement( new Float( rs.getDouble( i ) ) );
break;
case Types.DATE:
currentRow.addElement( rs.getDate( i ) );
break;
default:
System.out.println( "Type was: " +
rsmd.getColumnTypeName( i ) );
return currentRow;

If Vector<String> currentRow = new Vector<String>(); isn't correct because there's different types you must find superclass of classes that you add, in this case, Object.
Vector<Object> currentRow = new Vector<Object>();

Unchecked or unsafe operations in db connection pooling

You don't necessarilly have to install retro compilers - you can set the source and target levels on the compiler command line e.g.
javac -source 1.3 -target 1.3 ....That does not however prevent you from using methods (and I think classes) that don't exist in 1.3, only language features.
It's especially nasty when dealing with new overloaded methods, where it will allow you to use new overloaded versions that don't exist in the old language version when compiling, and will allow them to be used when running against a 1.5 JVM, but when run against a 1.3 JVM you get exceptions because the method doesn't exist there.
So be extremely careful using those flags, and test everything thoroughly against a 1.3 JVM (which kinda defeats the purpose of the flags, as it means you need one installed anyway so why not use that to compile in the first place?).

Jdeveloper warning uses unchecked or unsafe operations

Greetings:
I am getting warnings on my oc4j console that look like :
Note: C:\product\10.1.3\OracleAS_1\j2ee\home\application-deployments\pl\plBeans\generated\PlLoginPrefixesEJB_StatelessSessionBeanWrapper9.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
I get these when I use a JDeveloper created SessionEJB bean. Is there something i can do to "fix" this or should i just ignore it?
Thanks

Hi,
I have the following code which I have got from a book but when I compile I get a warning .... uses unchecked or unsafe operations.
class CompTypeComparator implements Comparator
public int compare(Object o1, Object o2)
    int j1 = ((CompType)o1).j;
    int j2 = ((CompType)o2).j;
    return (j1 < j2 ? -1 : (j1 == j2 ? 0 : 1));
public class ComparatorTest
public static void main(String[] args)
    CompType[] a = new CompType[10];
    Arrays2.fill(a, CompType.generator());
    System.out.println("before sorting, a = " + Arrays.asList(a));
    Arrays.sort(a, new CompTypeComparator());
    System.out.println("after sorting, a = " + Arrays.asList(a));
}I have met this error before in other code from the book and have been able to sort it by myself. This one I could not solve since I do not fully understand the syntax of the Arrays.sort() method. IE
sort(T[] a, Comparator<? super T> c)Presumably this error is because the book used an older version of the compiler than the version I am using (V5.0 or is it V1.5).
Could anyone explain the error, how I can solve it and what the sort method means particularly "? super T"?

Owner.java uses unchecked or unsafe operations.

     * @param g the is the Owner object
     * The method is used to add the owner
public void addVecOwners(Owner ow)

}          Above are the two type of sample coding I typed. I get the following errors when I typed it.
Owner.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
Please help me to get ridof the warning messages.

If you decide to use generics, you'll have to modify your code
everywhere you use the collections.
Before:
private Vector vecOwners = new Vector();
private Vector vecOwnerBoats = new Vector();
public Vector getVecOwners()
    return vecOwners;
public Vector getVecOwnerBoats()
    return vecOwnerBoats;
public void addVecOwners(Owner ow)
    getVecOwners().add(ow);
public boolean addVecBoats(Boat bt)
    boolean result = false;
    if (!getVecOwnerBoats().contains(bt))
        getVecOwnerBoats().add(bt);
        result = true;
    return result;
}With generics:
private Vector<Owner> vecOwners = new Vector<Owner>();
private Vector<Boat> vecOwnerBoats = new Vector<Boat>();
public Vector<Owner> getVecOwners()
    return vecOwners;
public Vector<Boat> getVecOwnerBoats()
    return vecOwnerBoats;
public void addVecOwners(Owner ow)
    getVecOwners().add(ow);
public boolean addVecBoats(Boat bt)
    boolean result = false;
    if (!getVecOwnerBoats().contains(bt))
        getVecOwnerBoats().add(bt);
        result = true;
    return result;
