[JavaScript] How to catch the error when the cache page is not found?

I want to use the cache of the navigator, to get data stored before (and not to send the same data) with AJAX. So I use the error 304 to tell that the page was not change, so use the cache instead. In the other navigator, there are no error, but only a blank responseText.
But with Firefox, the error "no element found" is displayed in the Error Console. Is there a possibility to not displayed it? Maybe with "catch" and "try", but I have no idea where to place it.
Thank you =)

Installed itunes update 10.5.0.142 and now get the error message "Disc Burner or Software Not Found" when trying to burn playlist to disc.

Installed itunes update 10.5.0.142 and now get the error message "Disc Burner or Software Not Found" when trying to burn playlist to disc. Windows 7

Hello queenabs,
It sounds like you are trying to burn a playlist to a disc in iTunes, but you are getting the error, "disc burner or software not found." I found a couple of resources that I think might help with an error like this.
I recommend starting with the steps in this article:
iTunes for Windows: Optical drive is no longer recognized, or "Disc burner or software not found" alert after install
http://support.apple.com/kb/TS2308
If you are still having trouble with burning a disc after following the steps in that article, I recommend following the steps in this article:

http://support.apple.com/kb/TS1374
Thank you for using Apple Support Communities.
Best,

HT1923 I can´t reinstall itunes. I updated and after downloading the latest version and installing it the error message: "apple aplication support was not found. it is required to run itunes. uninstall and install again. Error 2

I bought an iphone 4s. After plugging it via usb to my computer itunes demanded to update version to 10.3 or higher. I uninstalled itunes, downloaded latest version (11.0.2) and during installation process on "activating services" it shows error message: "installation failed, verify administrator priviliges" which i have because i sign in as my pc administrator. I click on ignore and it tells me itunes has been succesfully instaled but when i try to run it it shows the error message: "apple application support was not found. It is required to run itunes. Uninstall and install itunes again. (which i have done several times) error 2 (windows error 2)." Someone please help me with this problem. Thanks.

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Have a new itouch. I'm having trouble downloading iTunes. I keep getting the error message: Apple Application software was not found. Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTues again. Error 2.

I have a new iTouch. I'm having trouble downloading iTunes. I keep getting the error message: "Apple Application Software was not found. Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTunes again. Error 2." I have uninstalled and tried installing again and get the same error message. What do i need to do?
Lg

Install 7-Zip (free), or a free trial of WinRAR, and use one of them to extract the contents of the iTunesSetup.exe or iTunesSetup64.exe installer file, then try installing AppleApplicationSupport.msi as a standalone component. Even if it won't install you may get a more useful error message as to why not.

How to catch BCD_OVERFLOW error when passing value to formal parameter?

Hi,
catching runtime error BCD_OVERFLOW exception is simple. However, it's not possible to catch this error directly, if it results from assigning too big value to the formal parameter.
Let's assume simple code with local class lcl_calculator implementing functional method add with two input parameters i_op1 and i_op2 both of type i and result value r_result of type i as well.
The following code dumps, without the exception being caught:
DATA:
   lo_calculator TYPE REF TO lcl_calculator,
   l_result TYPE i.
START-OF-SELECTION.
   TRY.
       CREATE OBJECT lo_calculator.
       l_result = lo_calculator->add(
         i_op1 = 10000000000
         i_op2 = 1 ).
       WRITE:/ l_result.
     CATCH cx_sy_conversion_overflow.
       WRITE:/ 'Error'.
   ENDTRY.
To solve this, the workaround has to be implemented with checking the values being passed to the method before the actual call is made:
DATA:
   lo_calculator TYPE REF TO lcl_calculator,
   l_result TYPE i,
   l_op1 TYPE i,
   l_op2 TYPE i.
START-OF-SELECTION.
   TRY.
       l_op1 = 10000000000.
       l_op2 = 1.
       CREATE OBJECT lo_calculator.
       l_result = lo_calculator->add(
         i_op1 = l_op1
         i_op2 = l_op2 ).
       WRITE:/ l_result.
     CATCH cx_sy_conversion_overflow.
       WRITE:/ 'Error'.
   ENDTRY.
It's the same with the function module call, so it's general unit interface issue. Also, using the exception handling related to the CALL METHOD command does not help here as it's not wrong parameter TYPING which causes the error. It's the VALUE of correctly typed parameter that causes the error.
The CATCH apparently reacts different ways when the assignment is made to the variable and to the formal parameter of the unit. Any idea how to solve the above without using that workaround?
Thank you
Michal

What about using numeric?

TS1436 keep getting the error message saying " cd/dvd software not found". How do I fix this!?

When trying to burn my playlist, I keep getting error message saying cd/dvd software not found.. I've tried uninstalling and installing itunes over and over.. and I still get the same message . I can burn in Windows media player but not in itunes. Please help!

Could you post your diagnostics for us please?
In iTunes, go "Help > Run Diagnostics". Uncheck the boxes other than DVD/CD tests, as per the following screenshot:
... and click "Next".
When you get through to the final screen:
... click the "Copy to Clipboard" button and paste the diagnostics into a reply here. (Use your Ctrl-V keyboard shortcut to paste.)

Doublechecking, Dad:

Did you use the following document as a guide?

(If we're looking at program file damage down in Apple Application Support or Apple Mobile Device Support, the 2. Verify iTunes and related components are completely uninstalled section is very important.)

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.

Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

I keep getting the error box "firefox.exe- entry point not found" it says- ?alloc@nsmemory@@sapaxi@z could not be located in the dynamic link library xpcom.dll.

This happens on more than just the Denver post Broncos site but I notice it there most. When I get the error it locks the page load until I click the OK in the error box. This will happen multiple times as pages load. It started when I upgraded Firefox to3.6.8. If I keep clicking OK I can read articles but when the pages come up I have to keep clicking to make the error box go away, a real pain.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
Create a new profile as a test to check if your current profile is causing the problems
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

We cannot help without additional information:
Are you running your code
...in the development system?
...as a standalone application?
...deployed to an embedded target?
If it is a built application, do you explicitly include dynamically called VIs in the build specification?
Who wrote the program? Do you have access to the code?
How is this VI called? Is there sufficient error handling?
Do you manipulate paths as strings or as proper path datatypes with the strip path/build path primitives etc.?
Is it running on the same OS used to develop it ...

Video images won't load, error message says "problem loading page/server not found

when i select videos to watch, they have symbol in the top left hand corner but blank everywhere else. if i right click on the symbol i get an error message "problem loading page/server not found" but i'm already logged in to the website. this just started happening today after having watched 100's of videos for years on the same sites. i haven't changed any settings that i know of, but i have tried several different troubleshooting tips but nothing helps. i have windows xp. and i use firefox exclusively. what can i do?

'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
*In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br>
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
Please report your results.
