Don't function applet

Hello, I have problem, this applet shows error. How to fix it? I need this applet for school project. Thank you.
[http://www.uvm.edu/~mfuris/INTRO_PHYSLETS/contents/optics/refraction/prob34_2.html]

The Applet does not show any error running on my system and you don't say what the error is and even if it know what the error is we don't have access to the source. Surely you should contact the person who in charge of the site.

IPod 5G video + Belkin TuneTalk stereo recording don't function

iPod 5G video 30Gb + Belkin TuneTalk stereo recording don't function on firmware 1.2.1
every 48 second it skips for 1 - 2 seconds in HQ MODE
Belkin say: It's how Apple manage the write from storage to hard disc
It's a shame that this is already more then 5 mounths !!!!
no possibilaty to downgrade the firmware..;(
1 not one note on Belkin.com site (they still sell it !!)
or
2 on Apple update site
NOTE here on the discussion from januari 2007 !!!
When I record in stereo, it skips through out the recording. I'll be listening to what I have recorded, and I'll notice that chunks of about 3 seconds are missing from the recording
Mac OS X (10.4.9) G5

actually a very similar problem here. the recording was 35 min and it jumps and skips down to about 7 min. I thought it was a problem with the wav file that was recorded so I converted it to mp3 to and the same problem.
i do have firmware 1.2.1 but had never successfully used it before this attempt. did you ever get any resolution on this?

TextArea Validation Widget don't function with Prototype

I have seen that TextAreaValidationWidget don't function
properly if is loaded also the Prototype library. To verify, I have
also simply insert this code in the HEAD section of the
FormsValidation Demo included in the framework:
quote:
<script type='text/javascript'
src='prototype.js'></script>
By adding this file, the validation of text field is running
properly but the validation of textarea doesn't. The Firefox
console of errors report:
quote:
Invalid Quantifier +);} catch (e) {if!=$continue) {throw
e;}}});} catch(e) {if(e!=$break){thow e; }} return this;}\b
in SpryValidationTextarea.js line 785
Do you know how to solve this?
I use Spry 1.4, prototype 1.5.0 (because I use also lightbox
2.0)

Hi,
Based on a previous report we fixed this bug in the Spry 1.5
preview release. To fix this bug you should edit the
SpryValidationTextarea.js. Search for the:
Spry.Widget.ValidationTextarea.prototype.switchClassName =
function (className){
and inside you should see around line 763 the following code:
for (var k in classes){
if (classes[k] != className){
this.removeClassName(classes[k]);
This code should change to the following:
for (var k = 0; k < classes.length; k++){
if (classes[k] != className){
this.removeClassName(classes[k]);
Please let me know about your results.

Glad it helped. Everyone has been bitten by this at one time or another. Fortunately you only get bit once
Well if you haven't already read it two or three times the User manual is really very good. Apple really did a nice job with it. The on-line version is nice because it is searchable.
After that the Apple Pro Training Series book Aperture 3 is very useful. Its basically split into three parts. The library, adjustments and sharing. In addition if you get all the way through it you can take the Certification test and become, well certified.
Rwboyer who posts here on and off has a good site and a couple of ebooks that I found useful.
good luck

Volume buttons and mute button don't function in Windows 8 64-bit

Almost funny, I also have installed Windows 8 64-bit on my ThionkPad SL500 (clean install). I have read other people complaining about "Volume buttons and mute button don't function". This is exactly the same problem I have. I have found no exact procedure about what software to install to make this work. Instead people refer to other threads that often end in some desert... So, does anyone (Lenovo?) have a clear answer on what software to install (and links to those drivers please...) :-? And, yes, I have tried installing different software packages by following threads, but nothing has worked just yet... So, clear instructions / links, please :-)
Thanks,
Niels

I recently found this information on the micorsoft troubleshooting website and thought of your post, not sure if you had found a solution but hopefully it is helpful.
My keyboard volume controls suddenly stopped working
If the volume controls on your keyboard stops working, check the Human Interface Device Access service on your computer to make sure it is set to Automatic.
In the Start menu, type View local services.
From the Search Results list, select View local services.
In the Services dialog box, locate Human Interface Device Access. Make sure the status is set to “Started.” If it is not started, click Start the service.
Right-click Human Interface Device Access and select Properties.
On the General tab, in the Startup type, select Automatic, and then click OK.
Thank you for being a part of the Lenovo Family,

Apps on my Macbook Pro don't function/connect to the internet

For some reason some apps on my Mac will not work or connect to the internet. The ones not working are: iTunes (can't connect to the iTunes store but I can play media I have locally), App Store, Safari, Beatport App, and Adobe Reader; but I wouldn't be surprised if there were more that I just haven't checked. Safari and Adobe Reader both open and function normally for about 5 second or so and then just freezes and doesn't respond. Everything else just says it's opening but never actually does and eventually stops responding. I also can't do software updates for iTunes or my Mac in general.
I tried uninstalling Adobe Reader and installing it again from the Adobe website, but when I open the installer it doesn't respond either, so now I just don't have Adobe Reader installed anymore.
I also tried disabling my firewall and messing with my security/network settings but didn't have any luck. Anyone have any ideas??

Reboot into OSX, run Boot Camp, select Download Windows Support Software.
While that is downloading you will have time to Print the Boot Camp documentation and read it (clearly you have not yet)

But aside from notification sound alerts. The speakers don't work when playing music but work when earphones are plugged in. Very strange.

Macbook pro trackpad and keyboard don't function

I was working on my photography coursework monday night, and my keyboard froze, but the mouse worked. then I restarted it (losing all my unsaved editing, by the way) and neither the trackpad or internal keyboard worked. after that, for a few days, they both worked on and off, before completely ceasing to function.
I'm running 10.5.6, and I had to buy an external mouse and keyboard this evening.
my warranty has run out, I don't have apple care, and I cant go for more than 24 hours without my computer because we don't have another one in the house.
does anyone know what the problem may be, and how to fix it without being without a computer for the next god only knows how long? (the place I got my mbp from doesn't allow loaned computers etc.)
(I do not have the money to buy a new laptop either)
Message was edited by: Petite Lapine

Funny thing is I had the exact same problem last week. I run a Macbook Pro 2.2 intel. The laptop is alway in a studio, on a stand and connected to an external keyboard and Wacom tablet. I'll use the laptop keypad and trackpad maybe 1% of the time out of the day. The day I updated to 10.5.6 is when the keypad and trackpad stopped working.
I had updated to 10.5 about 2-3 weeks previous, after running 10.4 for over a year with no problems. The original Archive and Instal had so many issues that I was forced to do the new instal and wipe the hard drive. After a few calls to Apple regarding the 10.5 install issues, I was offered an additional 90 days warranty.
When I took it into Apple last weekend for the keypad and trackpad issues I was told that the warranty that was offered as a goodwill gesture didn't cover any hardware issues, only software. Apple ran through a few things on the laptop and also tried booting off a bootable startup disk and couldn't figure out the problem.
I did check the cable issue as described below and also went thought other resets that I have read about in other posts. All to no avail.
Apple has quoted a new top case assembly and a new keyboard. With labor I'm looking at a total of £205 to fix the issue.
Seems a bit funny for it to all happen so soon after my 10.5 purchase and also on the day of the 10.5.6 update. I'm aware of how may others may have done the same update with no issues but this laptop has been treated with kid gloves over the past year and a half. If I was rough with it, then I could except it but when it's been treated as it has been then I just can't understand it.
Any others with the same problems, it would be good to hear from you.

Can record comparisons be done without functions or PLSQL

I am used to writing Oracle functions to do record comparisons, however on this particular project the managers do not want to use functions or PLSQL
Is there a way to do the following with a SQL statement rather than writing a function - see data set below? Oracle 9i.
I have the following data set used to track packages that are moved from warehouse to warehouse on trucks
I only want to retrieve a record if the starting location is Dallas Ft Worth and the end location is another city.
I do not want to retrieve a record if the package moves between other cities (say Boston and New York)
For this data set package 1324 was added and removed to the warehouses at Dallas 4 times via truck 735 before it was finally moved to a warehouse in Boston by the same truck
I want the query to return the following record
105273     345          1324               725          11/3/2010 14:32               11/3/2010 15:46               Dallas Ft Worth          WH4
Showing the last location in Dallas before it was moved to Boston
I do not want to return any of the Boston or NY records or any of the previous Dallas Ft Worth Records.
The way the system updates the records is as follows:
If a package is added to a warehouse the record gets an added date.
When it is removed the system updates the removed date of that same record
Once it is added to a new warehouse there is a new record with an added date and null date for the removed date unless it leaves that location
In the record set if the removed date is null then that is the current location of the package

I tried to do a query with a subquery... the main query was getting all the records with Dallas Ft Worth and then the subquery was to check if the location was not Dallas Ft Worth, but so far I haven't quite been able to get the correct dataset.
Any help is greatly appreciated. I don't know if there is a way to do this with just a sql query, if not other suggestions are welcomed!
Thanks in advance

I added a couple of rows to your table, shipping the package back from New York to Dallas on a different truck, then back out from Dallas to New York just to make sure I understand the requirements.

Help - Why don't swing applet print, like awt applets do?

I am using JTable in a applet, but I would like to be able to print the applet using microsoft explorer. I had written a bulkier version of the same applet using an array of TextFields to establish a Table effecte. The code is bulking and loads slow in the browser. JTables work better but the applet shows up all black when I try and print it. What do I do to fix the problem? Do I have to use TextField if I want to print it? Any suggestions would be helpfull.

While waiting I dug deeper into the bugged section of code and found that:
divider.setBounds(0,62,600,2);
was the problem, and that:
divider.setBounds(0,62,600,4);
works.
Don't ask me why I couldn't tell you, but IE 6 doesn't like the heigth to be less than 4. If it is the entire applet prints out black.

Microsoft Office 2004 Products don't function on Mac OSX Lion

I installed Lion on both my iMac and Mac Book Pro. When I did the installs I didn't keep Snow Lepoard so I could boot either the old or new system. After signing on to Lion I notice that all my Microsoft 2004 Office products no longer function. I looked into the steps to re-install Snow Leporad but that doesn't look easy, its wasteful, and I might have to kep it around forever. Since I have an extensive number of Word, Excel, Powerpoint, and Access files does anyone know if the lastest version of Microsoft Office for Mac is support on Lion? The only other solution I see is to move exything to cloud version of office

If you don't need Exchange you can get Office 2008 H&S very reasonably from Amazon with free shipping. $89.75
Office 2011 H&S does not contain Outlook. In addition, Office 2011 now has activation and number of installs are different than previous versions.
See this chart to know which version to purchase.
Lastly, Outlook for Mac 2011 is version 1 software. Do not expect Outlook for Mac to be anything close to Outlook for Windows. Just because it's not storing your messages in a database it still has lots of issues that damages or looses your data.
