Is there no notification send to my applet when the browser window moves?
Hi there,
been perusing the forum for some time now but every time a similar question to mine was asked the answer I'm hoping for is lacking...
The problem is simple: I have an applet that needs to detect when it has been moved. Currently I have a timer that polls the applets getLocationOnScreen() and compares it with it's previous location. It works, but mymymy is this ugly! Using all that valuable processor time for the odd chance that this happens.
Is there really not some sort of event triggered that I can subscribe to (i.e. some sort of Listener interface that I do not know of?) that will just notify me when this has happened? I have tried adding a ComponentListener (only notifies of resizes), WindowListener, WindowFocusListener etc. to the JApplet class but to no avail.
Can it be done or not?

If you check for it once every half-second it would probably be plenty fast for GUI purposes but not eat up much processor time at all.

Inited applet closes the browser automatically
Hello everybody!
I�m new with java and have a strange problem excuting my applet with Mozilla and Internet Explorer but not with Mozilla Firefox.
I have been reading the forum but haven�t found any similar problem.
When I run my applet with Mozilla or Internet Explorer, it says 'Miniapplet inited' in the status bar and suddendly closes the browser window. However if I run the same applet with Mozilla FireFox it goes perfect.
Any idea?
Thanks in advance!!Don�t know what happened but now it is saying the java.io.IOException: CreateProcess: ... error=2.
As I have been reading it means there's no file. If I write down the complete path it goes fine. However, I would like to run an executable file which is in the browser but wanna be executed by the client, is it possible with getRuntime.exec()??
Thanks!! -
How can I email a video clip I downloaded into my iPhoto library to my friends? I tried creating an email and attaching the clip but there is no sound and no picture when the 5 minute attachment "plays." How can I file=>export it to them from iPhoto?
Have them install Quicktime on their PC's from Apple's website, that's the easiest fix.

Importing a lot of video clips from a Sony camera to FCE; during the Log and Transfer process, is there a way to add multiple clips to the browser instead of one at a time?
Select one and click cmd-A which selects them all.
Then click the import button if it hasn't started already. -
Is there a way to Quickly organize, consolidate & save the Original (Pictures, Movies, etc.) yet delete all duplicate (Pictures, Movies, etc.)?
I wanted to first thank you for this, as this is the only workaround literature that seems to be floating around out there. With that said, I know it is a big ask, but is there any way that you could create a video showing step by step how to do what you do? I have several tracks that are stuck in waiting mode, and if left in itunes, will never upload or match...they only cause the upload process to hang up and restart. I've tried leaving it for days...I've tried converting the files, signing in and out of itunes (and itunes match), updating itunes match, and I tried your technique...unfortunately to no avail. Perhaps I didn't do your technique correctly. I used audacity to reverse the audio.
ANY help would be GREATLY APPRECIATED!!!

Since the last upgrade, when the browser is open the mouse randomly clicks on things changes windows by itself. In addition highlighting things to cut and past is almost impossible... this transfers over to all open programs word, movie maker, audacity, etc... and as soon as the browser is close the problems go away... I am having this on two computers the first is a 32 Bit Vista system with a corded mouse the second is a dual boot 64 bit Win 7 and Linux Mint laptop using a Logitech cordless mouse and built in mouse pad both mouse and pad does this... in both operating systems.
I thought it was a problem with the mice or interference with the wireless receiver or from an Xbox in the same room interfering with the systems, however updated drivers were downloaded and installed on both computers for all three operating systems.'''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''' {web link}

Iv sent an iMessage to someone abroad but deleted it before it delivered, will it still send as an iMessage when the person has wifi?
Your question is a bit unclear. However, once the message is sent, it is beyond your control. You can't unsend it. If the person has an active data connection and an iOS device, it should show as an iMessage.

I need to send an email message on the ipad with a photo as an attachment "not" inline in the message? I do not want the photo embedded in the email message. I'm using exchange on the ipad.
Apple Mail will display attachments that are one page or less. While the photo will be displayed it is sent as an attachment. The recipient can click and drag the photo to their desktop just like any other attachment.

Automated Basic Authenication with an Applet for the Browser
Hi
I like to automate web access to secured pages and proxies, which are
proteced with a Basic Authenication scheme.
The Basic Authentication within an Applet works really well, I get all the
information I need when I attach the
Authorization: Basic base64encodeUID_PW to the request Header.
or
if I use the Authenticator Class of the JDK1.5.
My problem is that the browser do not notice that I already have a
UID/Password combination for the desired web page and I don't want that the Dialog
to enter the UID and Password comes up, when I access the Page later with the browser.
When I did the same with a form based authorisation the URLConnection was
setting the Cookie inside the browser implicitly, the showDocument() method
displayed the secured page, because the browser used the cookie to access
it.
Is there any way to access the cache for the UID and Password of the
browser to set these values, so when I invoke the showDocument() to
display the page inside the browser, I don't have to enter the UID and
Password again?
My current code to authenticate myself is this, I also tried a direct
socket connection and a HttpURLConnection there was no difference:
String urlString =
"http://www.demo.com/basicprotectedpage/index.html"
AppletContext appCont = getAppletContext();
//created password authenticator.
mmAuthenticator myPassAuth = new mmAuthenticator(uid,pw);
//setting password.
Authenticator.setDefault(myPassAuth);
//URL created.
URL url = new URL(urlString);
//opening connection
URLConnection conn = url.openConnection();
//setting do input and do output.
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(true);
//Data Input Stream
BufferedReader bin = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
String inputLine;
System.out.println("web page data " );
while ((inputLine = bin.readLine()) != null)
System.out.println(inputLine);
bin.close();
appCont.showDocument(new URL(urlString)); // this should
display the secured page without the prompt for uid password
Thank you in advance.
MartinThat is properly too late.
However, I am working on a similar problem. This is my insight. If anybody know more than I do, please let me know.
Using the applet, the Authenticator may not work due to the new JRE. I believe if you have the property file within your machine, you may get around this problem. Other than that, I have not figured out a way to get pass this security issue. Anybody have any thought on that ?
To get around this issue, in your case, it is Basic Authentication; so it won't be too bad. You will need to write your own http client. which mean, you will need to be able to read the response from the server and send the proper header back to the server. At least that is how I did it.
The problem I am facing now is doing Digest Authentication. I really hate to do all kind of work to get Digest working. Only if the Authenticator work for me.
Hope that help. -

Somebody has some ideas or suggestions please?

MaryHi there,
thank you for the reply. The thing is not having 2 sessions for one user, but to have 2 sessions for 2 users. Here is the deal: The main Website works with one layout, the links work with other layouts - all layouts are controlled by the user parameter. Image you at the Volkswagen website and want to visit the Audi (subsidiary of Volkswagen) website. Just for fun, image that the two websites run in the same environment and sometimes the share resources. To access the Audi resources you need to login as a Audi user. This causes the layout to be Audi specific. After having had a fast look at the Audi website you decide to close the window. All the time you had your Volkswagen window open in the background. Now, if you want to explorer the Volkswagen website, the user is set to Audi, and therefore all the Volkswagen pages will be shown in Audi layout ....
