[Resolved] Reading from text files

Getting Started Newbie Questions
#1

Hi all,

After watching Peach’s webinar last night I’m hooked! It was great btw.

I have a couple of specific questions that I would really like to resolve before diving in completely.

I have already created a desktop app for a client who now wants it to be available on iOS and Android. This app reads data from a txt file which is generated from another app I built.

At present the txt file is formatted using “;” i.e.

&Cercueil1=Toury;Cercueil en pin massif;Teinte claire;Finition vernis satiné;Côté mouluré;Couvercle en forme de dôme;5;2;Cercueil, 4 poignées, plaque d’identification et garniture étanche.;0;Cache vis;0;Emblème;

Each piece of data is read and put into different text fields or loads an image etc.

What I would like to know is if this is possible in Corona? I have found the functions to load a txt file and read it but I don’t seem to be able to find a way of accessing specific data.

The second question is regarding network connection.

I want to create another app where I want users to see how many other users are using the app at the same time. Basically there will be a counter at the top that goes up and down depending how may people are using the app. Is this possible?

Thanks in advance for the help.

Cheers

function split(pString, pPattern)  
 local Table = {} -- NOTE: use {n = 0} in Lua-5.0  
 local fpat = "(.-)" .. pPattern  
 local last\_end = 1  
 local s, e, cap = pString:find(fpat, 1)  
 while s do  
 if s ~= 1 or cap ~= "" then  
 table.insert(Table,cap)  
  
 end  
 last\_end = e+1  
 s, e, cap = pString:find(fpat, last\_end)  
 end  
 if last\_end \<= #pString then  
 cap = pString:sub(last\_end)  
 table.insert(Table, cap)  
 end  
 return Table  
end

should take care of letting you split the string after you read it in and put into a table for you.
