what a nice idea David.
 
I wonder if in the future, you could allow the user to position the browse
mode cursor on some price, and have him hit a hotkey and have the app
automatically speak the conversion to his local currency?  Maybe it could be
set to remember url domains or individual pages and what currency they price
their items in?  I see all kinds of work for you ahead!!! <smile>

Subject: Currency Calculator - Alpha-testers, was: What is the best way to
store a dictionary?


Chip and Jared,
Sorry for not being specific about this. My problem did arise, because the
user might interfere, or change these values from time to time. In other
words, they are not ever-static. But they need to be stored in the modified
version, so that this will be the value that is being retrieved next time
the app is run. 
 
Anyway, thanks for all help. The first Alpha version of my app should be
quite ready. Simple as it may be. I might need a couple of testers, though.
 
So, let me just explain shortly what the app is doing.
 
For all of us, who are shopping online, and who like to buy from abroad,
there is an ever ongoing challenge of calculating what a given price - in a
foreign currency - actually will sum up to in your local currency. If for
instance, you live in the US, and buy a lot of stuff from Canada, that is
priced in Canadian dollars, you will have to keep calculating the actual
price in US Dollars, so as to see if it is worth to buy from abroad.
 
Not a big deal. If the Currency Exchange Rate is 1.03, You can always bring
up the calculator of Windows, and enter the US * 1.03. But when you are
operating with several currencies, since you are buying stuff from different
parts of the world (like if you are shopping places like EBay), it becomes a
bit more of a challenge. You then will keep remembering what the Exchange
rate is for British Pounds, Canadian dollars, and Australian dollars, along
with Euros. 
 
My small app - for the moment called CCalc - will keep remembering the
actual exchange rate for each currency. The user can easily change - or
update - the rate for a given currency, or have the app displaying what the
stored rate is. First he has entered the rate for a currency, he can enter
things like:
 
    CN59.23
 
And if the Exchange Rate is set to 1.03, he will get the result 
    61.01
spoken.
 
Again, he could have entered things like 
    £10.92
for getting the exchanged sum of a buying in British Pounds, and have the
final sum spoken.
 
Entering things like
    AU=1.24
will set the Exchange Rate for Australian dollars to 1.24. This might
explain why I needed to store the values, but eventually have a chance to
update the values, depending on a user input.
 
At last, if the user wants to know what the stored rate is for a given
currency, he would enter things like:
    ?NOK
(That is the currency text, along with a question mark), and here get the
rate for the Norwegian Krone.
 
There is a few minor limitations, the way the app stands today. These will
be sorted soon as I can get my hands and time on it. But if anyone has the
interest of testing the app, please contact me at
    [email protected]
.
 
Thanks again for all assistance.

Hi David,
 
you don't really say if your app will need to update these values (say for
instance because of something the user does), or if they are not ever
changing, so you only need to display/speak them to the user?
 
If you only need to display them to the user, then the XML file is perfect
for this; there's no problem in adding as many strings as you like; any
other code in your app generated by the WEScripting Framework or anything
else will just ignore them, and as you say, you can internationalize it very
easily.
 
If you do need to change them, but you only have say a hundred or two, then
a .ini file will do fine.  yes, you can put numbers or strings in .ini keys.
You could for instance have each .ini entry consist of the string value
equals and it's associated number. (such as USA=1.02).
 
 
hth,
 
Chip

Obviously I don't know much about storing things, from a script. Smile.
 
My problem is, that I need to store information, holding two 'columns'. I
thought at first of using a dictionary. Secondly I was considering the usage
of the app's INI file. But I am really not sure any longer, what would be
the way to handle this the most smart. Thing is that I need to store info
like:
 
    Australia    6.5
    USA    5.55
    Denmark    1.0398
    Europe    9.02
 
As you can see, I will need a set of 'keys', with textual names. These has
to go along with a corresponding set of decimal numbers. 
 
As I said, I was considering using the INI file. But somehow, I got it from
the reference manual of WE, that you only can store integers for the INI
file. Is that so, or am I messing up my mind here.
 
I then thought of using the XML file, and store a set of strings there. But
these would have to be seperate from other strings in the XML file, or how
would my app distinguish them from strings of more general kind in my XML
file. Is there a way of 'grouping' strings in the XML? The benefit of the
XML, of course, would have been that I could have translated the textual
keys into each languge supported; of which there would be no way in the INI
file. But it is not a too big problem, since the info the user really would
need to get in touch with here, is the set of decimal values; hence he might
not care too much of the textual notation. 
 
Any good workaround for my issue? Thanks,
