I just signed up for the flexible Google Voice free service. It has many
cool features, but I was wandering if HomerJax WebRequests would be
appropriate for a few of these features. Particularly, I am interested in
their Quick Call
mobile web site page:
www.google.com/voice/m
It provides an edit box (name=number) and a Call button. When used the
service calls your number and when you answer, it will call the desired
number free anywhere in the US (as well as cheap international calls). I
currently have a script that grabs any selected text and adds it to a list
of commonly called numbers. It will extract the phone number, connect to
the mobile web site and enter the data. That way I can easily make a phone
call from Anytime Organizer or anywhere I come across a phone number. It
works, but it takes a while to load the web page from a Run statement. I
would think these WebRequests functions would be much faster!
Google Voice also can send SMS text messages. I don't think I will use this
since I can send these simply through email. Perhaps if I can write a
WebRequest function to monitor a response, it might be worth the effort.
Of course, you need to be set up with a free Google Voice number to get to
any of these pages. It will give you a free number you pick out of a list.
It is attached to a person or fanmily rather than a physical phone. From
their web site you can set up incoming calls to riing all of your different
numbers all at once, or or forward to particular phones or straight to voice
mail based on phone number. When you answer the call you have the option to
anser, answer & record, send to voice mail or send to voice mail & listen.
There Go to:
www.google.com/voice
and request an invitation. It is not widely available yet. I mostly use
the mobile pages because the main pages use ARIA controls. None of the
controls are recognized or work in IE/JAWS. The controls are recognized in
firefox 3.5.1, but some do not work as I would expect.

> HomerJax is a library of convenience functions for accessing Internet

> and is dependent on several COM servers distributed with Windows. The
> word "Homer" is a brand name I sometimes use for developer tools I create.
> The word "Jax" derives from Ajax, which originally meant "Asynchronous
> JavaScript and XML." Ajax technologies focus on building dynamic user
> interfaces in web browsers. HomerJax functions use some of these core
> technologies, but focus on reading, interpreting, and writing data from
> the Internet.

> is that this library makes it easier for developers, including blind ones
> like myself, to build applications that take advantage of new social
> networking sites such as Twitter, FaceBook, and many others. I intend for
> HomerJax to be accessible via various programming environments, including
> the Windows Script Host, screen reader scripting languages, and other
> programming languages via a COM server interface.

> Overview
>
> HomerJax methods are divided into categories indicated by a prefix at the
> beginning of their names: Dialog, File, Folder, Html, Js, Path, RegExp,
> Registry, String, Vt, Web, and Xml. By convention, HomerJax variable
> names use lower case prefixes to indicate the data type: s for string, i
> for integer, n for floating point number, l for list, d for dictionary,
> and o for other COM object. Method and variable names use upper camel
> case (like the .NET Framework), e.g., XmlGetValue rather than XMLGetValue.
> JavaScript is a case-sensitive language, so methods need to be called with
> appropriate capitalization.
> ----------

> COM Exchange Format
>
> The Component Object Model (COM) is a set of Windows standards by which
> different programming languages and applications can communicate. COM
> uses a flexible data type called a variant, which can be an individual
> value, array of values, or complex object with methods, properties, and
> events. In general, any COM client can use string, numeric, and COM
> objects as the data types of parameters or return values. Some, however,
> cannot use arrays. COM exchange format is intended to support
> collections, as well as primitive data types, for use by any COM client.
> Rather than an array, a list COM object is used from the .NET Framework
> (any version). A COM object dictionary is also used from the Windows
> Script Host.
>
> HomerJax includes a method called JsToVt, which converts data in JSON
> format to variant types understood by JAWS Script (or any COM client
> language). JavaScript arrays are converted to COM objects with the progID
> "System.Collections.ArrayList." The methods and properties of this object
> are documented at
> http://msdn.microsoft.com/en-us/library/system.collections.arraylist.aspx
>
> JavaScript objects, which are like dictionaries, are converted to COM
> objects with the progID "Scripting.Dictionary." This object is documented
> at
> http://msdn.microsoft.com/en-us/library/x4k5wbx4(VS.85).aspx
>
> In Visual Basic and other languages, either of these types of object
> collections may be iterated with the "For Each" statement. These objects
> have an "Item" method, which is the default COM method of the object, so
> syntax can succinctly referr to items without even using the "Item"
> keyword (just using an integer element of a list or string key of a
> dictionary enclosed in parentheses). The code of the demo program
> illustrates this in getting public messages from Twitter.

> HomerJax includes various methods for converting between JavaScript Object
> Notation (JSON), variant data types, and COM exchange format. This
