Check for wifi and 3g connection
I'm using the following code to check for a network connection. This seems to work fine with wifi, but I also want it to work if I only have 3G connection. How can I do this?
Boolean success;
const char *host_name = "www.domain.com";
SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL, host_name);
SCNetworkReachabilityFlags flags;
success = SCNetworkReachabilityGetFlags(reachability, &flags);
_isDataSourceAvailable = success && (flags & kSCNetworkFlagsReachable) && !(flags & kSCNetworkFlagsConnectionRequired);
CFRelease(reachability);
Have a look at the "Reachability" example app. It does just what you are looking for (though I don't think it differentiates between Edge and 3G).

Why yahoo/gmail retrieval and facebook app so so slow when in WIFI. But using the internet to check for emails and facebook is fast using the same WIFI connection??
Hi SandyS_VZW,
Yes tried resetting the wifi connection and problem still persist.
Here it is...to make it clear. Connected thru the same wifi at home...
-> emails (yahoo/gmail) and facebook WEBSITES are working fine and fast when using/accessing thru a browser (chrome/samsung browser) - no problem with this.
-> emails (yahoo/gmail) and facebook APP is soooooo sloooww (thru the App). Slow I mean comparing it to using their browser/websites... news feeds/emails refreshing so quickly but not when using the APP installed in Samsung Galaxy Note 4. Slow like - It will take around 5-10minutes just to get your emails and news feed refreshed.
THIS HAPPENS ONLY WHEN CONNECTED THRU A WIFI which has a speed of 10-20mb. It is not happening when connected to the network data/plan.
My wife has the same Samsung Galaxy Note 4 (coming from different provider at&t) - same setup (emails, fb app), same wifi connection, but she's not experiencing anything like it.
Not sure why, I dont want to believe that while connected to a WIFI, Verizon is restricting anything and ******* me off to make me switch to my data plan connection everytime - which is Unfair!
Was there a known issue similar about this case?
thanks, -
i have problem with my wifi in 4 S, i cant connect to any wifi itried resetting network setting and reset all setting but the result was the same, its only keeps searching for wifi and cant find any, itried to use OTHER but also didnt work.please help me???
If Join was on then your home wi-fi must be set to Non-Broadcast. If you did not set this up (maybe your provider did) then you will need to find the Network Name they used, and any password they used. The SSID is Security Set ID and to see more try http://en.wikipedia.org/wiki/SSID . Basically it is the name used to identify your router/network. A lot of times the installer will leave it set as LinkSys, or Broadcom or whatever the manufacturer set it as for default. Your best bet is to get whoever installed it to walk you through how they set it up, giving you id's and passwords so you can get in. HOWEVER, if you are not comfortable with this (if you set security wrong, etc.) you would be well ahead of the game to hire a local computer tech (networking) to get this working for you. You can also contact the vendor of your router and get help (if it is still in warranty), or at least get copies of the manuals as pdf files. Sorry I can't give you more help, I hope this gives you an idea where to go from here to find more.

When do I know if my iphone will switch to wifi and not that it costs somemoney to my phone network operator? is there a spec setting I must do.
Or is it enough to have the phone set to wifi and phone connects directlywhen it makes contact with a wifi network?Thank you again for all of your help!! I really appreciate it!
I think I am following -- I was able to upload to my iPhoto and all photos and videos are there that is a plus! I tried to create an Event in my iPhoto and put all of my photos in that event but for some reason, now my iTunes it not recognizing that Event in my iPhoto. It is not allowing me to import just that event at the moment but I may be doing something wrong. At least all of my pics and vids are in iPhoto so that is a plus and I know they are at least saved somewhere. Just for some reason, my iTunes it not locating the event that I created with only those photos.
Thank you for letting me know about my contacts! How do I know if I have the contacts app?
Also, I had no clue that my iCloud could be backed up via cellular data! However, is this a new feature with the most updated iOS?? Unforutnatly I am like 2 iOS updates behind because I don't have enough storage on my phone. I still get the notification that my phone needs to be plugged in and connected to wifi in order to back up to the cloud :-(
How can I sync using USB? Right now when i click on the info tab for my iPhone in my iTunes this is the answer that I get -- I am a little unclear as to what it means.
Sync Contacts:
Your contacts are being synced with you iPhone over the air from iCloud. Over-the-air sync settings can be changed on you iPhone

My Apple TV froze while trying to access Netflix. I unplugged the Apple TV from the wall and re plugged it. Now it stays on the loading time and date setting. After 10 minutes, I held menu, and hit restart (as the troubleshoot said). Same problem is still occurring with the continuous "checking for date and time". And if I hold menu to bypass this, I only have my settings and computer icon, all other icons have disappeared. Not quite sure what to do, any comments would surely help.
Thanks guys, appreciate it.
MattApple TV 1st generation or 2nd?
I would try plugging in the HDMI from the ATV to a different HDMI port on your TV and even trying the ATV on a different TV altogether...sounds like the HDMI port on your TV might be bad or a bad connection. Keep in mind you'll need to switch the TV input to the new HDMI port -
Check for null and empty - Arraylist
Hello all,
Can anyone tell me the best procedure to check for null and empty for an arraylist in a jsp using JSTL. I'm trying something like this;
<c:if test="${!empty sampleList}">
</c:if>
Help is greatly appreciated.
Thanks,
Greeshma...A null check might not be you best option. If your requirement is you must have both the date and time component supplied in order to populate EventDate, then I would use a Script Functoid that takes data and time as parameters.
In the C# method, first check if either is an empty string, if so return an empty string.
If not, TryParse the data, if successful, return a valid data string for EventDate. If not, error or return empty string, whichever satsifies the requirement. -
I have installed itunes 10.7 several times, all goes well. After reeboot, I go to check for updates and it still wants to update to version 10.7! I cant sync to my iphone4 because I get an error message saying I need version 10.6.3 or later. Help
Thank you for getting me started on the track by mentioning "Revo" Uninstaller. The results of "Revo" spoke volumns on why a successful install of ITunes is so difficult to achieve. It is the evil "BONJOUR".
I then tripped upon the following site by Apple and the detailed directions (I read, printed, re-read and followed the instructions. It was intense) brought a successful ITunes, Quick Time and the lovely Bonjour home. Thank you for the start JD42.

How can I Create a Client Configuration File for RemoteApp and Desktop Connection with Server 2012?
I have a working RDS RemoteApp site and looking to test out the feature in Windows 7 Control Panel\All Control Panel Items\RemoteApp and Desktop Connections
I came across this link: Create a Client Configuration File for RemoteApp and Desktop Connection and I believe this is what I need to do first, but these instructions are for
Server 2008, and I'm running 2012.
Any suggestions or tips on how I can begin testing this with Server 2012?Hi,
You can manually enter the path to the 2012 feed and it will connect and download the RemoteApps and Desktop connections.
If you need a sample .wcx file I have posted one here a couple of times. If you want I will look for it and post a link.
-TP
I tried adding my URL's below, these are sample links that work for me right now for when I log into the web page, but neither of these work. And I'm not sure what I would need to do with or how to create a .wcx file.
When I type in my URL of: https://connect.mydomain.org/RDWeb, I get redirected to:

I just bought a (used) Iphone 3gs for wife and it had angry birds and $89 Navigation on it (I paid extra for it). Once updated and logged into my I-tunes it no longer works? How can I make those apps work?
Apple doesn't have anything to do with this other than enforcing the DRM protection. The developers of this content expect to be paid if someone wants to use their content. When you purchase content in the app store, you purchase a license to use the content. This license does not permit you or anyone else to resell or give this content away. The individual you purchased the phone from simply does not have the right to sell or give away any purchased content on the phone. You were deceived.

Duplication check for Lead and Contact
Hi,
Can i confirm that, there is no duplication check for Lead and Contact during the new reacord adding?
I also realise that during the Lead convertion, CRMOD also never check for duplication even i have existing contact available?
Is there anyway for us to activate the duplication check during the Lead convertion?
Regards,
SKSK,
System can check duplicate if you add external id for record (Lead and Contact).
For more information please refer topic 'About record duplicates and external ids' on page no.1303 of OnDemand help.
Hope this helps.

TS3899 email was working then all of a sudden its "checking for updates" and wont update
My Iphone 4s was working fine and now I can't get the email to update. I have deleted my account and it still isn't working. Everything else internet wise is working, just not the email. Any ideas?
I can send emails, but when it is "checking for mail" and the circle is moving, it never stops, just keeps searching. I checked my email from my computer and I had 10 new emails, so I know they are waiting for me, I can't even retrieve emails that I have read and are still on my account. It won't bring up the accounts at all
