values in combobox!

[anil]

hello everyone!
again me;

i wanna create number convertor but my project is a little bit difficult.
i can not solve and i need big help.
my flash version is Flash MX.

my project will be like below...
---------------------------------------
"input text"

"combobox1" "combobox2"
value1               value1
value2               value2
value3               value3


"button"

"dynamic text"
------------------------------------------

Jorge Solis helped me for two value in combobox but i can not write script to third value and more...

Below script is perfect for two value but it's diffucult to write script for new value(example value three=yourMoney).


convert.onPress = function(){
 if(A.getSelectedItem().label==B.getSelectedItem().label){
     dollar.text = "Select different money"
     return
 }
 qty = Number(dollar.text)  
 if(dollar.text=="" || isNaN(qty)) {
     dollar.text = "Enter a sum"
     return
 }
 myMoney.text = (A.getSelectedItem().label=="dollar")?qty*1.5 : qty/1.5
}


thanks to read this long letter....

Hi,
you only need one combobox having the currencies.

Then you need an array, or db query to find a matching value, and the factor for it.

If youre base currency is €, and your target currency is $, then you only need the number to be multiplied from $ to €.

You can read these once from a file, and then access them from an array.
I would write a XML file, for the ease of reading, and changing it.

Youre XML could be looking like this:
[code]
<exchangerates date="20040809">
<currency label="USD" symbol="$" factor="0,95" />
<currency label="EUR" symbol="€" factor="1" />
<currency lable="YEN" symbol="Y" factor="unknown" />
</exchangerates>
[code]
then you can read all labels into the combo, and if the usere selected one, you can directly read the factor an present the symbol

Hi Anil,
I dont see the need for two comboboxes

What do you select in the second one?

Comboboxes are userinterfaces for to select values out of a list.
If you just need an internal list, you make an array.

Ronald;

my project will be like below...
i don't need any connection.
i think to create website about number convertor (like weights ton/kg/lb etc..). It will be similar with currency convertor in this site but i need no connection like nusoap because all data in script will be stable.
i think that 2 combobox and inside same labels.
Jorge Solis helped me for two labels but it's difficult to write script 3 and more...


---------------------------------------
"input text"

"combobox1"  "combobox2"
value1               value1
value2               value2
value3               value3


"button"

"dynamic text"

 }
 qty = Number(dollar.text)  
 if(dollar.text=="" || isNaN(qty)) {
     dollar.text = "Enter a sum"
     return
 }
 myMoney.text = (A.getSelectedItem().label=="dollar")?qty*1.5 : qty/1.5
}

OK, in this case two combos make sense.

But you have to create some logic, that you cannot calculate pound into cm or celsius into pascal

So you would need to load the second combo, after you made a selection in the first one.

The fist combo has all the labels for the calculation base and data for the corresponding file to be loaded into the second combo

So, if you have selected meter in the first one, you get a base number of 1, and a file (like lenghts.xml) containing mm, cm, dm, m, km, yards, miles, feet .... with the corresponding factor in the data field.
