ar.abolghasemi · August 11, 2015, 2:39pm

Hi

I’m use this code for write time data, but i’m do not find “time.txt” on phone,where save this file(“time.txt”) ?

If this code do not worke fore saving file(data), What functions can I use?

local path = system.pathForFile( “time.d.txt”, system.DocumentsDirectory )

local function updateTime()
local time = os.date("*t")

    local saveData = time.hour
    local file = io.open( path, “a+” )
    file:write( saveData )
    io.close( file )

    local saveData = “:”
    local file = io.open( path, “a+” )
    file:write( saveData )
    io.close( file )

    local saveData = time.min
    local file = io.open( path, “a+” )
    file:write( saveData )
    io.close( file )

    local saveData = “:”
    local file = io.open( path, “a+” )
    file:write( saveData )
    io.close( file )

    local saveData = time.sec
    local file = io.open( path, “a+” )
    file:write( saveData )
    io.close( file )

end
local clockTimer = timer.performWithDelay( 1000, updateTime, -1 )

Help me please

Hi. I answered a similar question in this post:

In that post you can get the code to read and write files as well as an example at the end demoing how to use the code.

Whether you’ll be able to find the file on your device… I don’t know. I just know my code works and will allow you to read and write files.

Hi

Thank for your help.

I’m used this code for write time data with your function but i can not find txt file (myTest.txt) in my device.

Can’t help you with finding files on your device. I assume you mean you want to plug the device into your PC and find it that way? I’m going to assume it will be hidden from you, but I never do this, so… don’t know.
Please format your code with code blocks:

This is bad:

local function doit()

print(“Some hard to read code”)

end

This is good (and will get more answers):

local function doit() print("Some properly formatted and displayed code") end
