Count Lines in a String

[Dominic_Fichera]

Hey everyone!

I'm trying to make a script where a user can add "names" to a list and it will randomly pick a result... Sort of like a lotto.



I'm trying to work out a way for my script to work out how many names have been added. Can you think of a way to count the number of lines in a variable.

For example, if my variable was:

Name 1
Name 2
Name 3

Could my script work out there were 3 names here so I could then make it pick a number between 1-3. (Once I know how to count the lines, I should be right with the rest!

Thanks in advance for your help!

*UPDATE*

I've been able to answer my own question by digging through some old forum posts and using the separate function!

As an additional question, is there anyway to now decide "okay, my random number is 2, what is sitting on line 2 of the combo box"?

Thanks again!

Same way really. Get list of items, use Separate to get into an array, look up item at random position:

Code: Select all

//get a random number between 1 and 3
Random>2,randnumber
Add>randnumber,1

//get the list of items from combobox
GetDialogProperty>Dialog1,MSComboBox1,ListText,itemList
Separate>itemlist,CRlF,item_array

//get item at random number position
Let>random_item=item_array_%randnumber%
