Can Linux recognize the escape character?

Hi,
It's possible that this problem doesn't belong here. But please give it a try.
I am developing an project using JSP. It includes image uploading. after image uploading, I use a javascript function popUp(url, ...) to open a new window and display this image. The very strange thing is that, sometimes the link can work, open a new window and display the image while sometimes the link can't work, or it only works for one time, then it fails. I couldn't find the reason yet. it works on IE, and not on Netscape and also not work on Linux OS while do work on Window2000. Can somebody take a look at the following link and tell me how to change it to make sure it is work on Linux OS and netscape. What's the difference between OS and windows to specify a String(that is, url of a link). The linux OS seems interperte \" to ", so it cannot recognize the full url.
The link is :
imageLink[i] = "<a href='showForm' onclick=\"popUp('" + request.getContextPath() + "/displayForm.jsp?filename=" + sdb.getImageFileName(i)+"&fileDesc=" +sdb.getImageDesc(i) + "', 'showForm', '600', '450', 'yes'); return false;\">"+sdb.getImageDesc(i)+"</a>";
Thanks in advance!

Linux will recognize the escape character. It looks like you might have other difficulties with your imageLink tag. For example, I think you need to use tags when you use Java inside your html or javascript..
onclick=\"popUp(" + <%= request.getContextPath() %> + "/displayform.jsp?...

I can't recognize the DVD RW Optiarc

Dear Sir,
My system can't recognize the DVD RW on my Entertainment Notebook HP Pavilion dv6815el.
I've upgrade it to Windows 7 12 months ago, without problem, but from 5 days I've big troubles!
Maybe for some mistake, using Nero or Alcool virtual drivers, there is an incompatibily beetwen drivers.
Iìve suddenly unistalled those programs, but as in Device manager as on windows explorer I can't see it anymore
It seem to work only fiew seconds lighting and noising, when I load a CD or DVD, after it stops.
I tried with fixwin and by modifiyng regedit; now I tried your checks as suggested, but no results; there isnt!
And I can't open DVD/CD-ROM Drives find it in order to find and uninstall it..
I find only the HD drive and, if plugged, a external DVD RW.
Also restoring old system images, I cannot fix the big bug.
By driverwhiz I can see it; Pls see my shots as follows:

At last, I can't see, as in other models of HP notebooks, in the bottom, under the battery, the small screw in order to put out or change this Optiarc device, if damaged.
Help me please!!!!

Hi,
The easiest solution may be to run Windows System Restore. If you have Norton Internet Security installed, you will need to disable Nortons Tamper Protection as shown in Step 2, on the link below.
http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20091112171719EN&ln=en_US
Once you've done this, shut down the PC. Windows System Restore is usaully best run in Safe Mode. Tap away at f8 as you start the PC to enter Windows Recovery Console. Use the arrow keys to select Safe Mode and hit enter. When this has loaded, from the Start Menu, click All Programs, click Accessories, click System Tools and launch System Restore. Pick a restore point before the problem occured and then proceed with the restore process. Windows will reboot as normal.
If this doesn't work or you do not have a restore point earlier than the problem, try the automated fixit from Microsoft on the links below.
Windows 7
Check if the drive is now working.
If the drive is not working, from the Start Menu, open the Control Panel and click on Device Manager. Click to open the IDE ATA/ATAPI Controllers. Right click on the first channel and select uninstall. Do not delete drivers if asked. When uninstalled repeat the process for each channel. Also if an ATA controller is listed, right click and uninstall this, again not deleting drivers if asked. Then open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked.
Reboot the PC and let Windows reinstall the devices. Check the drive again.
If it still isn't working, run the automated fixit from Microsoft on the link below again.
Windows 7
Next, from the Start Menu, open the Control Panel and click on Device Manager. Next click to open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked. When the device has uninstalled click on the 'Scan for Hardware Changes' icon ( usually just below Help on the toolbar ). Let windows reinstall the drive and see if it now works.
Hope this helps.

My hp dm3-3027cl card reader can not recognize the class 10 sdhc card

My hp dm3-3027cl card reader can not recognize the class 10 sdhc card. I downloaded and installed the card reader driver from HP web site for this dm3-3027cl, but still have same problem. There isn't a problem on class 6 SDHC card. It seems some other computers have the same problem on reading the class 10 SDHC card. My toshiba e105 laptop has no probblem to read class 10 SDHC card.

Hello snowman90024 and welcome to community,
Kindly install the USB and card reader driver then install cardreader driver and USB driver
Please let us know about the status after this.

Hi, can someone help me how can i connected my multimeter to my pc with rs232, because my computer can´t recognize the device, i mean the multimeter, is a multimeter keithley serie 2400, and i already downloaded all the drivers for labview even the VISA

hi, can someone help me how can i connected my multimeter to my pc with rs232, because my computer can´t recognize the device, i mean the multimeter, is a multimeter keithley serie 2400, and i already downloaded all the drivers for labview even the VISA

Marco,
Here are some suggestions:
1) Check the manual the Keithley manual to see how to configure the RS-232.
    On some models you need set Factory defaults to USER and turn on the RS-232.
    Also there may be a setting for SCPI which you want on (probably on by default).
2) On your PC - open Device Manager. See if a COM port exists and is functional.
     You must get this working before continuing.
      You can set the COM port parameters by right clicking and selecting Properties.
     (On some PCs the onboard ports can be disabled in the BIOS)
3) If step two was OK, open MAX (Measurement and Automation eXplorer).
    On the left side, click on Devices and Hardware.
    Click on Serial and Parallel.
    Go to the COM port you found in Device Manager.
    Open a VISA Test Panel.
    Now I don't have one I can look at right now, so this is general idea:
   Configure the COM port to match the Keithley settings (should be OK if step 2 worked)
   Go to the (I think) Input Output tab (you want to send a command)
   The command string input should already have a *IDN? entered, if not, type it in.
   Click on the Query button to send the command and check the response.
   If you get an ID string back (Company name, Model, FW Version ...) then it works.
   (Disregard an error saying it did not get enough charcters back.)
I hope this helps,
steve

Apache Tomcat 7.0.4 can't recognize the classpath for .jar files

Hiii Everybody,
I have a weird problem. I am trying to develop a simple application where I am trying to pass an excel file name as an argument to a method and the method creates a copy of the specified file. I have used jxl.jar for excel file manipulation. During this I have faced two problems.......
1) I tried to compile the file CopyExcel.java in the command prompt(windows), sometimes the file is not compiled and the error shown indicates that it can't recognize the package jxl. But if I close the command prompt window and open it again.... I could compile the CopyExcel.java succesfully with no error.
2) Even if I have compiled the CopyExcell.java file successfully, whenever I am tryiyng to call a method copyMain() inside it, browser shows....

Ah, that explains why i see "European Set"....
One question, Doug: Obviously, you can select only the localization there. Is this PostScript Characters for all languages? Or is it possible to switch to something like true types, e.g. "Wingdings"? (I know, bad example, but i hope you get the point)

Hi ,
Do you remember if you have installed some software prior to this issue?
Delete programs you never use.
If the issue reoccurs in Clean Boot, but works fine in Safe Mode, the cause may be the disabled hardware drivers. You may narrow down the
causes in Device Clean Boot.
Device Clean Boot
=================
1. Click Start, type "devmgmt.msc" (without quotation marks) in the Search bar and press Enter.
2. Expand "Sound, video and game controllers".
3. Right click on your sound card and then click "Properties.
4. In the dropdown menu of Device Usage, please choose "Do not use this device (disable)" and click OK.
5. Please use the same method to disable other dubious hardware such as: internal modem, network card and CD-R drive. Please note some devices
such as video adapter are not available to be disabled.

Help!- ipad was disconnected when updating software...now it won't recognize the ipad and can't complete a restore.It can't recognize the serial # or name,etc..

i was updating my ipad to the new ios software. the cable got disconnected just as it was completing the update. when it connected again it said i need to restore it. Once going thru the restore process, it said that Itunes can't recognize the ipad. one note, the ipad shows on my itunes as a "IPAD" and no name, serial #, etc... The ipad has a symbol on it telling me to connect to itunes

A System Reset cures many ills. It's easy, quick and harmless:
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears.
A System Reset does not remove any apps, music, movies, etc. nor does it cause any settings to revert back to default.
Also, you might wish to download the iPad-2 User Guide. Pay special attention to page 162. Note that this Guide also applies to the iPad-1 with IOS 4.3 except for those functions that are not supported by the hardware.
http://support.apple.com/manuals/#ipad
Finally, the User Guide can be downloaded at no charge via iBooks and a less comprehensive version of the Guide is included as a Safari bookmark.

How can I stop the last character of my password from being displayed?

Sorry, I'm sure this would have been asked before, but I couldn't locate it..
When unlocking my iPad, how can I stop it from displaying the last character of my password to everyone in the vicinity? This has got to be the fastest way to find out someone's password (just look at the screen as they type their 'secure' password!?). Having the iPad display your password letter by letter is really not acceptable when working in a non-secure environment.
Is there a setting somewhere, or will this be addressed in a new iOS, or just ignored as a 'that's the way it is'?
Thanks in advance,
Andy

Hi,
This may have been the way it has been on iOS since 2008 (not sure about that though), however I know (based on working in the IT industry for 20 years) that nobody on this planet can successfully argue that it would be 'acceptable security practice', for me to display 'every last letter' as I type of a secure 'root' password on my screen every day when you log in... Nobody would think it acceptable to display even their LAN/Domain password on the screen in this same manner. So why is iOS different?!
iOS on a phone (it used to be argued) doesn't need to be very secure as it is almost entirely phone numbers and email addresses that are being stored. However in recent years when the applications got better, and tablets came out, security became a much bigger issue as more and more people started using the functions of 'smart' phones to store more 'sensitive' data.
Kind regards,
Andy
Are you suggesting that someone looking over your shoulder can't see the keys that you're tapping with your fingers? In the interest of security, i would never, under any circumstances, enter a password when others are around.

Can I enter the 'wait' character in a phone number in Contacts?

I am accustomed to being able to enter a 'pause' character and a 'wait' character when entering phone numbers in my phone's address book.
'pause' causes the phone to pause a certain number of seconds (typically 2 or 4) before sending the characters which follow it. 'wait' causes the phone not to send the characters which follow it until you press the send button again.
On the iPhone, the 'pause' character is a comma (on my old Motorola RAZR it displayed as a 'p' in the phone number entry).
But I can't find a way to enter the 'wait' character (on my old Moto RAZR it displayed as a 'w'). Is there a way to do this?

There is no "wait" character for the iPhone, and I miss it also.

What is the escape character for DOT in java regex?

How to specify a dot character in a java regex?
. itself represents any character
\. is an illegal escape character

The regex engine needs to see \. but if you're putting it into a String literal in a .java file, you need to make it \\., as Rene said. This is because the compiler also uses \ as an escape character, so it will take the first \ as escaping the second one, and remove it, and the string that gets passed onto the regex will be \.

What do I do if my iTunes can't recognize the internet connection?

I really need to restore my iPod and upgrade iTunes, but for some reason iTunes can't recognize my internet. I know the nternet is working, because everything else internet required works. IT's just iTunes that doesn't. It has always worked before, but I don't understand why it won't now. Does anyone have any ideas or suggestions? I'd really appreciate them. Thankyou.
