Applet Flashing

I know this may seem trivial to some of you more experienced programmers out there, but that's exactly why I'm posting here. . .
I'm writing a JApplet to do some fairly simple medical imaging manipulations (windowing/leveling, zooming, etc.). When I scroll over the applet and part of the applet is being clipped, it produces a terrible flashing effect.
I know that the effect is probably caused by the browser invoking the painting method as I scroll with a part of the applet being clipped. I have overridden the paintComponent method to do custom painting and am using double buffering (on by default in the Swing environment). I am doing my painting in a custom class extending JPanel. I can't think of any other pertinent information.
Is there a trick around this problem or is this problem inherent to the Swing architecture?

Applet (flashes when repaint is called)

How can stop my applet from flashing when repaint is called? Someone had mentioned the update method from class component. Can anyone tell me how to use to eliminate the flashing?

called? Someone had mentioned the update method from

You may also want to look into double-buffering.

Applet Flash problem

I have an applet and a flash in two frames in a HTML page. The applet and the falsh app communicate through the Javascript code with in the HTML pages. The flash app does not work as it is supposed to when the applet is present in the Parent HTML page. When I removed the applet, the flash app seems to work ok. But the applcation that I am working needs both of them together. Plz suggest me a solution if you know of any flash and applet related problems.
Thanks in advance.

How to create a sequence of flashes ...

hey i'm trying to create a simple version of a simon says game. where the applet will have (some image) and it will flash (some image) in differnent sequences. i want it to randomly choose a sequence - that's the first part... then I would like to have the sequence extended on the next time around... I can't really explain it but here is some code that I have but I can't really understand it
//     Setup the sequence array
public void sequence() {
    int prev1= 0, prev2= 0, curr;
    for (int a= 0; a<imgSquare; a++) {
      while (prev1 == (curr= rand(7) + 1) || prev2 == curr) ;
      prev2= prev1; prev1= seq[a]= curr;
    seqLength= min_seqLength;
   //     Random numbers
int rand(int siz) {
    return Math.abs(rand.nextInt()) % siz;
} i think this is what is supposed to happen, but i'm very new to java so I am not really sure what to do first.
I would like to have seven squares on the applet and each applet flashes in different sequences, the first one short, the next one longer...and so on.
can anybody please help me out with this???
how should I structure this program and where should I start first?
Thank you in advance

The basic idea here is,
--> Store the images in an array of size 7
loop {
--> Randomly generate an integer in the range 0 to 6
--> Get the image out of the array with this random index
--> Update the image on your applet square(or whatever)
} // end loop

Applet overlaps HTML elements

Hi,
Anyway not to let Applet overlap other HTML elements? I saw this is a classical problem in applet/flash. But one workaround in Flash is using a parameter: <param name="wmode" value="transparent">. This can let HTML elements be on top of Flash.
So are there any similar ways in Applet?
Thanks!

I am sorry for not describing the problem clearly.
The HTML elements here I mean are those with an absolute positioning, for example, a flowing <div> element which has an intersection part with an applet and should be exactly positioned over an applet.
An article has shown the phenomenon in Flash. In that article the "Search Form" is an HTML element which should be rendered above the Flash objects.
However, in most cases, objects like Flash and Applets usually ignores z-indexes assigned to HTML elements and are always on the topmost and covers these absolute positioned HTML elements if they overlaps. That article hints me about having a parameter like "<param name="wmode" value="transparent">" to force the Flash object rendered below the HTML elements, but I just cannot find a similar way in Applet.
Any suggestion? Thanks!

Keypress on componets (yet another item flash can't do)

yet again, something that is one line of code in other
languages that flash can't do....
1. Write component
2. I want to respond to a keypress to a movie clip or other
item in the component (say an input field or other movie clip)
this.onKeyPress only works when defined from root. i.e.
mc.onKeyPress() = function....
How the fukkk am I do to this from a component?
And I don't want a keylistener, as I don't want one in every
class/component. And no, I don't want code on the root. The point
is to have an encapsulated compoent.
Can this be done, or is flash a crap development tool. Time
to use Java applets, Flash soooo sucks at anything other than
making pretty pictures.

Here's the problem in a nutshell
class myComp extends MovieClip
private function onRelease()
{ trace ("the mouse clicked the comp on the stage")}
private funcion onKeyUp()
trace ("this event should fire for a keypress when the comp
ahs the focus, but it does not because Flash sucks azzz");
Only the top works.
the kicker is the onKeyUp is in blue just like onRelease,
becaues the intellisense is so craaapppy in Flash.
Way to go Adobe! Better crank out more bloated versions of
Reader. 30 Meg programs to read 10k files.

How to stop Flashing

I've been told that you can stop Java applets flashing by using buffers. How do I go about this? I'm a beginner with Java so can I have some specific code please.
Thanks,

the kyword is using double buffering
here at the sun site are some examples of how to create doublebuffered applet, but if you use swing and JApplet, then you may get by thet problem even more eeasily, since swing components have built in support for double buffering....
oops, seems that JApplet doesn't have support for that...
but you may have other swing components on your JApplet that have DoubleBuffering turned on...
and remember that you don't need to turn double buffering on for all the components... if one of them allready is doublebuffered then children of that component are afected by it as well...
why not run a search on "double buffering"

Output Mutiple Files Using htp.p

Hello,
I wish to output 3 CSV files from APEX I have the following code
Declare
S_FileName VarChar(20);
S_Counter Number;
begin
-- Set the File NAme
S_FileName :=To_char(sysdate,'yyyymmdd')||'Letters.CSV';
For S_Counter IN 1..4 LOOP
-- Set the MIME type
owa_util.mime_header( 'application/octet', FALSE );
-- Set the name of the file
htp.p('Content-Disposition: attachment; filename="'||S_FILENAME||S_Counter|| '"');
-- Close the HTTP Header
owa_util.http_header_close;
-- Loop through all rows in EMP
for x in (select MPAN_CORE,ACCOUNT_NO
from Categoriser.LTNA_LETTER_ONE_OUTPUT@link_to_dqmDevdb )
loop
-- Print out a portion of a row,
-- separated by commas and ended by a CR
htp.prn(x.MPAN_CORE ||','|| x.ACCOUNT_NO ||','||
x.MPAN_CORE || chr(13));
END LOOP;
END LOOP;
-- Send an error code so that the-- rest of the HTML does not render
htmldb_application.g_unrecoverable_error := true;
end;
At this stage i only want to output 3 files the content is not a issue
I it possible to do this with APEX?
Any help on this is greatly appreciated.
David

I take it from the lack of response that this is not somthing that APEX can do?No, it's something that HTTP cannot do. Think about it: if it was possible for a server to send multiple files in response to an HTTP request, then it would be possible to break your computer very easily indeed.
aww well looks like i will need to find another way..You'd need something in the browser client-side, Java applet, Flash control etc...

Pages Per Second, User Modes

What is being recorded in the Pages per second metrics, is it:
1) The DOWNLOAD and (emulated) RENDERING of the page with its attributes/objects (pages, images, frames etc)
OR
2) Just the DOWNLOAD of the page with its attributes/objects.
Does this change between User Modes i.e. Thick and Thin Client

Hi Paul,
A page is the eTester representation of what would be a web page in terms of navigations and actions that are performed in the web browser after the document is completely rendered and before the last transition.
Open the navigation editor and take a look at the Navigations tree. There it can be seen how the pages are divided. Each page will have between 0 to multiple navigations. Pages with zero navigations doesn't count, these pages won't even be shown in the report. If the page have frames the page will show more than one navigation. If the web application uses ajax or a similar technology with http transactions, or if the page uses java applets, flash objects or activex controls that makes http transactions and the proxy recorder was On, then the pages most likely will show more than one navigation.
eLoad will request all the navigations contained in any given page of any script in your load test scenario, if the web server will responds back successfuly for all the navigations, then this is counted as one page received. eLoad willl be requesting multiple pages from the different scripts that exists in the scenario submitted then it will count how many of those pages are being received in an interval of time, then makes a units convertion of the time interval in order to display it in seconds.
The pages received per second is the average of how many pages with all the navigations contained in it were successfully obtained from the web servers every second.
The pages per second is the same statistic regardless if you are running in thick or in thin.
The pages per second doesn't take into consideration the download of images, scripts, css, or any other object. These are considered in the hits per second.

Html page hides jframe

I developed an application using jdk 1.2.2. Rcently we updated to 1.5.1. The html page that calls the applet opens. You can see the applet flash, but the html page then hides the applet. If you minimize the html page the applet shows, but I really don't want users to have to do this. I have tried using the visble(), toFront(),show(), and requestFocus() methods but to no avail. I have changed the code on the html page to reflect going after the 1.5.1jdk. Thanks for any help you can offer.

MBP Retina Overheating while closed

Two or three times in the last few days I've left my MBP closed and plugged in, only to come back to it blazing hot. SMCFanControl reads 90-105 degrees Celsius when I open it. The fans immediately pick up once opened and cool it back down to reasonable levels in a few minutes, but I am quite concerned about this behavior. The last time this happened the computer restarted itself after only 10 minutes of away time, I would assume because the processor hit dangerously high levels.
I am quite certain that there were no programs running that would normally make it overheat (no applets, flash, games, iOS simulator,etc.). I can't understand why the computer would heat up so much and likewise why the fans are not kicking in while the computer is asleep?
Any word on how to fix this or shuold I be going directly to Apple Care?

Heat that is generated in a MBP is a function of the activity that is being performed at a given moment. Text editing and light web browsing will result in very modest temperature. Video, Skype and other CPU intensive applications will create a lot of internal heat, at times exceeding 100 c.
Now if the temperature start exceeding previously determined levels, there are sensors that will initiate a shutdown so that a MBP will no commit Hari Kari. One of the reasons that MBPs have a reputation of being 'hot' is the aluminum case. One must understand that it it part of the thermal dissipation scheme which helps in keeping the internal temperatures at reasonable levels. A plastic case would tend to be an insulator thus confining the heat internally and putting more heat stress on the internal components.

HT2434 Can a logic board, RAM, or processor core be compromised if an attacker gains root access?

If an malicious attack on my computer gained root access from a poisoned program (java applet, flash, unix executable) Could that attacker permanently poison my logic board/PRAM-VRAM or have access from the processor if everything else was (scrubbed)??
Someone gained keychain access on day one in the first 10-15 min. while I was setting things up thinking that the apple firewall was on by default. (Former PC user-oops) I was nailed by a vicious email attack-lucky that it only worked on the yahoo side and it was not opened by (mail) on my MBP. I was also nailed by a brutal PDF, Safari, Quicktime attacks while using Snow Leopard (Mid 2010) In OSX LION, someone was constanly changing my password after waiting for me to restore everything. Then it was a directory services hack. This is why I am concerned. I still see strange activity in console.
Thank you for your time! Mac is still enjoyable to use but the popularity has made it a huge target.

RAM is not the issue in a Mac Pro with Xeon processor, unless you get a distinctive kernel panic, machine check. Otherwise, every Read from memory is checked by Hardware and errors are corrected on the fly, with essentially no slowdown. In the Mac Pro silver tower or dark cylinder, Memory problems do not fester undetected.
panic(cpu 8 caller 0xffffff800d8dcc1d): Kernel trap at 0xffffff7f8df3d00c, type 14=page fault

Page fault is a reference to memory out of bounds (you do not own). It is most often caused by software.
If you remove the hexadecimal addresses from the stack trace as shown above, the list of what extensions were at the "scene of the crime" becomes much more clear. That is why I could see that your external (SCSI architecture) drives were implicated, and thomas_r. could call out the highpoint driver as being involved.

Do I need to pass a applet test with Java before the Flash player will function?

I have downloaded the unstall and install programs for Adobe Flash Player and followed all the steps poster, "eidnolb" noted to prior poster greenie41180 on March 6th, 2010, 8:05PM.   The flash player test did not work.   I also do not see applets, when I use the latest version of Java on an applet test.    I might try reinstalling IE8, or going to IE7 and reinstalling Flash Player. Gawd! hours have been used, just trying to get Flash Player going so I can resume watching the tutorials at Mathtutordvd.com.
What other troubleshooting steps can be taken?   I have tried everything eidnolb suggested in prior posts.
Hello everyone, When I try to download the Flash player I get the error message listed above.    I turned off the firewall and virus modes on my TrendMicro protection program, when downloading the player.     I already have Java 6, update 18 in the system.   I restarted the computer. I also adjusted the configurations for Javascript and ActiveX under the "Tools" menu for the Security and Advanced tabs of Internet options. I have Windows XP, service pack 3, with Internet Explorer 8.
Also, I tested the recent, most updated program, Java and I still can not see an applet.    I have spent 7 or more hours on this. I thought initially this process was going to be straight forward.     I desperately need this Flash player so I can learn math at the streaming video site called, Mathtutordvd.com       Oh! gosh maybe someone here can help me help myself by giving me more troubleshooting steps. I did follow Adobe's troubleshooting steps, but I still get the same, above error box with, MSXML2.XSL Template 3.0 (Original exception: undefined)
I hope, eventually to watch the streaming site, once this Flash Player is loaded.   I really do not understand what is going on here. Thanks for your help.

Running a java applet from flash

Hi,
How do you run a java applet from within a Flash movie?
Is it necessary for the user to download a java interpreter, or is there an interpreter somehow built into their browser that can run applets?

I was wondering , I don't know too much about Flash
I remember seeing some classes in amongst the Flash
files when it installed , but couldn't tell you whart they
do (at the moment , but you've got me interested)
maybe you should rethink your strategy for building your page (and your movie) maybe build the movie around
your applet , or preload it then replace a an area of your movie area with your applet (the way you handle rollovers).
the advantage is you can make calls to applet methods
from Flash as it supports Javascript.
jus remember to set the scriptable <PARAM> to true
Users shouldn't have to download the plug-in or JRE
you should specify it in the OBJECT or EMBED tag so
if they don't have it , the browser will tell them.
of course this is going to change as Microsoft are stopping support for JAVA , users will then have to download the plug-in from Sun in order to view or use JAVA on the internet.

Firefox+Flash: Some flash applets' content doesn't get updated

Hello community,
I stumbled upon a very strange problem with Firefox and Flash. Some flash applets (example: http://www.kenken.com/game) show only a plain white rectangle. For a long time I thought that it is a problem with Flashblock and/or NoScript. Today, however, I tried to get rid of the problem and made following observations:
1. The problem persists in safe mode (with deactivated extensions).
2. The problem persists after disabling hardware acceleration in the Firefox settings.
3. The problem does NOT occur in Chromium&Pepper Flash. But I'd like to stick to Firefox for many reasons.
4. The problem does NOT occur on my laptop running Manjaro (however, the setups are not really comparable).
5. Initially I thought that the flash applets aren't initialized at all, however, now I observed that if I switch to a different tab and then back to the tab with the flash applet, it gets updated. I can also interact with the applet, however, the changes are only visible after I do the tab switching.
Any help or hint how to find the cause of the problem is greatly appreciated!
Thanks in advance,
PhotonX

A new finding: I tried to install an older version of Firefox and downloaded a binary from https://ftp.mozilla.org/pub/mozilla.org … /releases/. The older binary worked so I tried newer ones and finally arrived at the very same version as the one installed through the package management. The result is: The 33.0.2 binary downloaded from Mozilla works, the 33.0.2 installed through the package management doesn't! All extensions installed on my machine are available in the downloaded binary, so I assume that it knows about ~/.mozilla. What could be the cause of the problem then? Will try to start Firefox with a completely clean home folder (new user) and report back.
