LS Getting the error "The data could not be saved because the server could not be contacted" when deploying on my local desktop

Hi:
I have a very simple test LS App:
1 Table "Person" with 1 property "Name"
One totally standard Editable Grid
So no complicated calculations that could timed out...
When I hit F5 the screen launches and shows the data, but when I try to create a new Person it waits for about 2 minutes and then the following error appears:
The data could not be saved because the server could not be contacted. Please check your network connection and try saving again. The Operation timed out.
Despite the error the data gets persisted on the database.
I am on VS 2013 Pro Update 4 and SQL Server LocalDB 2012 (v11.0).

If you decide to try again I would:
1) Uninstall Visual Studio
2) Uninstall SQL Server (all versions)
3) Re-install SQL Server
4) Re-Install Visual Studio

I get the following error when trying to open a pdf file... '*pdf.part could not be saved, because the source file could not be read"

I get the following error when trying to open a pdf file... '*pdf.part could not be saved, because the source file could not be read". I am able to open pdf files in IE and other programs.

I am encountering the same problem -- though with .qfx files from my bank. This worked fine in Firefox 31 ESR, but since upgrading to Firefox 33.0, I get the "<name>.qfx.part could not be saved, because the source file could not be read" when I attempt to download. (I should add that downloading PDF statements from the same site works fine, and that the qfx downloads work fine in IE and Chrome.)
I tried safe mode, it is still broken. Tried v34 beta, no luck. I reverted to version 31, it works again.
I guess I will stick with the older version until a solution is found...or just use an alternate browser to download my financial data.

Solved for me.
I set the owner/permissions of my profile's mozilla folder's (and all the files in it) to read/write access, and the problem disappeared.
in linux:''
* cd /home/myusername/.mozilla
* chown -cR myusername:mygroup ./
* chmod -cR +rw ./
'''Never do that with root privs (nor with sudo)'''

Hi Elmer,
I researched this error message, I think you can try the methods below:
Increase the timeout of the connection between the client and the server
Increase Client timeout, and it is set in the Application class in the Client Project
For further information: Error message: Unable to save data

"ABC could not be saved, because the source file could not be read" error when downloading

Almost every time I download a file, the download gets to the end and then I get this error "<filename> could not be saved, because the source file could not be read", and then the download fails.
I checked my addons and they are not the problem. This doesn't happen when I try another Firefox profile. I tried several solutions offered in "http://kb.mozillazine.org/Unable_to_save_or_download_files" but they didn't help. It's not my antivirus.
I hate to start another profile because I have my current one just the way I like it.
Please help!

You can check the file attributes of all the files in the Firefox Profile Folder to make sure that you have write permission.
*http://kb.mozillazine.org/Profile_folder_-_Firefox
Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
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)

Just downloaded iTunes to new dell laptop, tried syncing my iPhone get an error message: "this iPhone cannot be used because the Apple Mobile Device service is not started". What does this mean? I have had this phone for over a year..

Just downloaded iTunes to new dell laptop, tried syncing my iPhone get an error message: "this iPhone cannot be used because the Apple Mobile Device service is not started". What is the issue, had this phone over a year??

I had this problem before. I like to disable extra services to speed up my computer and I disabled the Apple Mobile Device service and had to re-enable this.
You can do that by going Control Panel>Administrative Tools>Services. Once you have gone to the services window, look for Apple Mobile Device and right-click. Select "Properties". There should be some information about the service as well as the label "Startup Type" with a drop-down menu beside it. If it says "disabled", that is your problem; Change the selection to anything except disabled (Automatic is easier and ensures that you can sync as soon as itunes opens).
If this doesn't work, I would look into your anti-virus' settings. Good Luck!

How I can diable in firefox dialog box "download error could not be saved, because the source file could not be read. " standart download manager when file not downloaded

It is possible that anti-virus software is corrupting downloaded files or is interfering otherwise.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
See:
*http://kb.mozillazine.org/Unable_to_save_or_download_files
You can try to set the browser.download.manager.scanWhenDone pref on the <b>about:config</b> page to false.

In trying to update I received this message: Firefox 3.6.3(2).dmg.part could not be saved, because the source file could not be read.

In trying to download an update I first received: "There were problems checking for, downloading, or installing this update. Firefox could not be updated because: No data was received (please try again)" It also gave a link to download manually. When I tried from the Firefox website I got: /Users/(deleted for privacy)/Desktop/Firefox 3.6.3(2).dmg.part could not be saved, because the source file could not be read.
Try again later, or contact the server administrator. I tried this 3 times.

Could not be saved because the source file could not be read.

I tried to download and after a while, this error message: ''[filename] could not be saved because the source file could not be read.'' I've been on google searching but I could not find the answer can someone PLEASE help me. it happened when downloading a game and I've already seen a few times before but it was less important.
sorry for the bad english I used a translator.

This problem isn't only happening with Firefox 4, for windows, as the System Details, and Tags indicate.
I'm using a Mac laptop (OS X 10.5.8 -- Leopard), using Firefox 6, and have been having this problem with large files for quite a while ... possibly since FF 4, but definitely with FF 5. The large files I've had the problem with are in the 500 - 900 MB range, and from commercial sites as well as most recently with a zip file containing photos from a friend which he uploaded to dl.dropbox.com ... attempted it numerous times, after trying the various suggested "fixes", and each time at around 255 MB, the download quits, with the error that file cannot be read from the server.
The various proposed solutions I've found on the web -- resetting the user configured options connected to downloads in FF config (about:config); deleting the compreg.dat file in the FF profile folder, don't pause the download (never have done this) etc.
Others have opined that the problem is flaky intermittent WiFi, or Security/Anti Virus software interfering with FF's accessibility to the file during the download; or a caching problem at one's ISP -- HOWEVER Safari doesn't experience this problem at all. Each time that I've experienced it in FF, I launch Safari, and can download the file completely without any errors.
Would really like to see someone from Mozilla respond to this ... lots of us are experiencing it.
Whatever happened to Netscape's ability to recover from download interruptions and resume a download at the point where it had been interrupted (like when a dial up modem dropped the line in the middle of the download) -- sure would be useful to see that feature come back in FF.
Thanks,
Muiz
