#include <Array.au3>


;;automation to run functions from files
$maxFun = 35


Global $v[1]

For $l = 1 To $maxFun Step 1
_ArrayAdd ($v[$maxFun] = FileReadLine("C:\IanLogTest\functionLog.log", $l))
Next
MsgBox("", "count", $v[$maxFun])

so that is my whole script... what i want it to do is have $maxFun be a text document and the maximum number of lines in the text doc is 35 at any given time.. and then add each line as an element to my array ($v[]). i just dont know how to create a blank array without using 35 ["",""...] as "blank" elements... is there an easy way to do this with a FOR loop? i feel that there is..

or should i just write out 35 variables and then $var1 = fileReadLine...... over and over.?

Thanks

LetsAuto,

Look at FileReadToArray in the Help file = it puts each line of a file into an array element for you.

And also look at ReDim to see how to resize an array if you ever need to.

If you just declare the array as "Global $v[36]" the array will be empty already. BTW, you need to declare it to 36 because you're starting the For loop at 1 and running it 35 times. Here's one way of doing it.

#include <Array.au3>
;;automation to run functions from files
Global $maxFun = 35
Global $v[36]
Global $hFile = FileOpen("C:IanLogTestfunctionLog.log") ; use a handle when using FileReadLine, it's much faster
For $l = 1 To $maxFun ; The step isn't needed if you're only incrementing by one every time.
    $v[$l] = FileReadLine($hFile)
Next
MsgBox("", "count", $v[$maxFun])
FileClose($hFile)

Or do it this way without the loop.

#include <File.au3>
;;automation to run functions from files
Global $v[1]
_FileReadToArray("C:IanLogTestfunctionLog.log", $v)
MsgBox("", "count", $v[$maxFun])

Awesome, thanks a lot! i had not found FileReadToArray because i just used FileReadLine without looking through the help files. ill post again if i run into issues

[Melba23]

LetsAuto,

without looking through the help files

Always a good idea to look there.

@Melba23, agreed i will make sure to scan through that next time.

@BrewManNH, if i want that message box to display all 35 lines, could i do something like....

MsgBox("", "count", $v[1] To $v[$maxFun])

??

[BrewManNH]

You can't do it that way. You'd have to create a string to display it. Look at _ArrayToString, and use @CRLF as the Delimiter parameter.

[Melba23]

LetsAuto,

You will have to put all the elements into a single variable:

$sCount = ""
For $i = 1 To $v[0]
    $sCount &= $v[$i] & @CRLF
Next
MsgBox(0, "Count", $sCount)

or use another of those functions hidden away in the Help file:

MsgBox(0, "Count", _ArrayToString($v, @CRLF))
