“I got a frosty reception from my dentist when I asked for advice on going elsewhere for cheaper services!” Well honestly Dave, what kind of reaction were you expecting? A quick rundown of the best cheap clinics in Budapest? Perhaps a list of phone numbers thrown in for good measure, or a timetable for train services to Newry.

Hi Dave,
How can I use the gears api’s to retrieve latitude and longitude when I have cellid, lac, mnc and mcc with me. The following is the link from google/apis but I could not find any sample which can help me.

Hi Dave,

I still have a problem accessing app offline.
Let me explain how am I doing it so that you can give me some idea:
I have two files (ggears_c.php and ggears_c.html).

I have online file ggears_c.php which has php script and gears script (checking if gears installed, activating my site, sync using workerPool, listing data fetched from Local DB and Create Desktop shortcut).
When user syncs data here (in php file), I am executing HTML file (backend using AJAX) ggears_c.html (for offline use..doing this since when user clicks on ‘Create Desktop Shortcut’ it points to ggears_c.html page and I think this html page data should be in cache for offline use).
Now when I go offline and click on shortcut, it shows ‘not connected/failed to open…).
Is there any problem using two files.
My online file (ggears_c.php) includes headers,jquery,css files.
Please guide me.
Waiting for you reply.
Thanks,
Ravi

Hi Ravi, I don't think you need to write the script separately, but when you're accessing resources (such as requesting data) there should be a way of checking whether the resource is available online, or if the offline resource (e.g. the local database) should be used. When I was doing this, I used a script that acted as a gateway to the data; if the data was not available online, the script used the offline resource. This was based on the Gears article on application architecture.

Hi Dave,

I have implemented sync part using workerPool (thanks alot for your tutorial).
Thanks for the url for offline use. I am going through it.

I have a doubt for offline usage:
Do I have to write script separately for off-line version ?
I think it’s the same which I implemented for online use….when user goes offline, he/she accesses the same page…right ?
I don’t have to add separately the script for offline version !

Thanks,
Ravi

Hi Ravi,

Thanks for the comment, glad to hear the tutorial helped!

Yes, I’d guess the browser hanging is because the sync is using up too many of its resources (which should be helped by moving it to the WorkerPool).

On the offline usage – the url should be the same one you use for online access. I’m not sure what the issue is when you refresh the browser (why it isn’t loading the off-line version). There is a good article at http://code.google.com/…/take_app_offline.html that gives steps for off-line conversion and tips & caveats that might help…

Hope that’s of some help.

Dave.
