hi karina.
that looks very useful. yes, please post it on your blog. i'm not sure it's
an exact fit for my problem but i'm making some progess here.
for example, i have a starting date as a date object and based upon what the
user
selects, i can calculate an increment. the only remaining unknown is how to
calculate it over a 13 month period. here is what i've got so far:
infusionDates.push( startingDate ); // set the initial start date in the
array.
// user selects 1 infusion once a week
if( infusions == 1 && weeks == 1 )
{
increment = 7;
for( i:Number=0; i<4; i++ ) // but '4' here is wrong. what value do i use
to represent 13 months??
{
infusionDates.push( startingDate += increment );
}
}
thank you very much for your help. -- matt.

Hi Matt,
If what you're looking for is a way to subtract two dates, then it's your
lucky day...
I just wrote an Age Counter component that displays how long it's been
since
a specific date (years, months, hours, minutes, and seconds). It's for a
client who wants to show how long his pediatric center has been running (a
very long time...): http://www.belilovskypediatrics.com/en/about.htm
Anyway, you don't need the whole class, just the relevant function which
is:
function getAge (year:Number, month:Number, day:Number):Date {
//Founded day or birthday
var founded:Date = new Date (year, month, day);
//Today
var today:Date = new Date ();
//Time difference in milliseconds
var mil:Number = today.getTime () - founded.getTime ();
//The age, in a date format
var age:Date = new Date ();
//Set the age (in relateion to 1970)
age.setTime (mil);
//Adjust the year
age.setYear (age.getYear () - 70);
return age;
}
The function returns a Date format, from which you can easily extrapolate
everything you need -
var age:Date = AgeCounter.getAge (1970, 6, 12); //That's my birthday, send
me a card ;)
Note: The month is 0 based, so don't send me that card in June, but in
July
;)
The day is 1 based, so my birthday is indeed on the 12th
And get the various age differences between dates like this:
age.getYear(),
age.getMonth(), age.getDate(), age.getHour(), age.getSecond()
If you need exact hours, just add them to the method. See docs for
creating
a Date object.
Anyone - let me know if you want the AgeCounter component itself, I'll
post
it on the blog.
Cheers,
Karina

hi.
i'm building a scheduler app for people who need infusions
over a 1 year period. a user selects the following info to begin:
1. a starting date for first infusion - day, month, and year
2. number of infusions - 1-4 3. frequency of infusions -
every 1, 2, 3, or 4 weeks.
i have to come up with a schedule of infusion dates over the
next 13 months.
the breakdown of infusion frequency goes like this:
CASE 1: user selects infusions per 1 week period.
a. 1 infusion every week -> increment every 7 days b. 2
infusions "" -> increment every 4 days c. 3 infusions "" ->
increment every 2 days d. 4 infusions "" -> alert ("max 3
infusions/week" );
CASE 2: user selects infusions per 2 week period.
a. 1 infusion every 2 weeks -> increment every 14 days b. 2
infusions "" -> increment every 7 days c. 3 infusions "" ->
increment every 4 days d. 4 infusions "" -> increment every 4 days
CASE 3: user selects infusions per 3 week period.
a. 1 infusion every 3 weeks -> increment every 21 days b. 2
infusions "" -> increment every 10 days c. 3 infusions "" ->
increment every 7 days d. 4 infusions "" -> increment every 5 days
CASE 4: user selects infusions per 4 week period.
a. 1 infusion every 4 weeks -> increment every 28 days b. 2
infusions "" -> increment every 14 days c. 3 infusions "" ->
increment every 9 days d. 4 infusions "" -> increment every 7 days
the way i figured to do it would be to capture the starting
day and month and then calculate ( based on number of
infusions and frequency ) every other day and month over a 13
month period. i'd throw all of these values into an
'infusionDates' array and then i can loop over them and
change the properties of the DateChooser that i need.
i just need help figuring out how to populate the
infusionDates array. can anyone help me get started, please?
thanks for any tips. -- matt.
