Using Dropbox/Online file to Verify Run

Not sure if this questions has been asked because I didn't know how to word the search. Please direct me if it has.
I am trying to add a feature to programs that I write to add a layer of protection incase programs end up with people that I do not want using it. I heard of a way to do this using a personal file located online (DropBox, GoogleDocs, etc). Your program checks this document for a 1 or a 0, etc. etc. etc.
I tried doing this with dropbox and google docs but really don't know how I would even start this to work consistently. Any help or initial direction on how to start this would be great. Thanks.

BLE GATT - what is easiest way to see the 'schemas'?

Am I the only missing the viewer info to see all attributes in GATT and GAP? A simple and quick lookup of for instance this one (doesn't work anymore) seems to indicate it is easy to find the required info (in my case the UUID's and descriptors):
https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.characteristic.cycling_power_feature.xml
I have clicked on quite some menus and I am sure I just overlook something. But I just cannot believe the BT organization makes a website with so little links to the actual info.
Any guidance?
There doesn't appear to be any links from the site, but it does look like you can look at the document directly:

XPath Data Scraping From Online Community

I recently read this article on how to scrape the Inbound.org community members profile using Excel. And you can watch the video here if you prefer it that way.
Since the release of this tutorial, the Inbound website structure has changed a bit, as you can see at minute 11:00 in the video, if you attempt to copy the XPath of the social media icons it appears slightly different and because of this I haven't been able to extract that information.
Here's what I get now:
/html/body/div[3]/div/div/div[1]/div/div[2]/a[1]/i
This is how I wrote the syntax in Excel:
=XPathOnUrl(A2,"//a[#class='twitter']","href")
And then like this:
=XPathOnUrl(A2,"//a[contains(#class,twitter)]/#href")
Although I tried in many different ways, none of them showed me the link to the member's social media profile.
I even tried changing the xpath in multiple ways to get different data from the page, but none of it was the social media information:
=XPathOnUrl(A2,"//*[contains(#class,member-banner-tagline)]/div[2]/div/div/div[1]/div/div[1]")
=XPathOnUrl(A2,"//*[contains(#class,member-banner-tagline)]/div[2]/div/div/div[1]/div/h1")
I honestly don't know what to try anymore, something's wrong and I can't figure it out. Anybody have enough experience with this or can pinpoint the problem here with my syntax?
Thanks a lot
The first formula you tried looks fine, but this is the one that works for me (SEO Tools version 4.3.4) :
=Dump(XPathOnUrl(A2;"//a[#class='twitter']";"href";HttpSettings(TRUE)))

I want to make voip applicaton in j2me.I surfed about mjsip2ME. I want to use mjsip with my application. Can any one suggest me for how to do this ?
There's a tutorial, but it is kinda incomplete at the moment, as it does not contain source code, and some sections are labeled "TO DO". However, it contains the list of methodw, with descriptions and a quick, general help.
There's also some info on the web not on the official site, but I hope you're not afraid of chinese :/

How to call and save contact in Java ME?

I am doing a program using j2me and the last window in the program has a form that contains name of the place, number and location.
I want to know:
if there is any way to call for the number which appears in the window?
if there is any way to save the information (name and number) in the contact?
any tutorials or examples applied this feature << because I searched a lot and I didn't find something useful.
You can use the midlet.platformRequest("tel:[telephone number]") to make the call. As far as accessing contact in the phone or saving contacts to the phone's address book, your phones needs JSR 75 API functionality and you might also require to sign the build
