GUI version of Tail

[blademonkey]

Try this, this works for me, continously generating tail until i click the button to stop.

expandcollapse popup

#include <File.au3>
#include <Array.au3>
#include <GUIConstants.au3>

$s_FileName = "test.txt"
Dim $a_Lines
Dim $read = True

GUICreate( "Tail Function - Continuous File Monitoring", 200, 200 )
$stop = GUICtrlCreateButton( "Click here to end file monitoring.", 10, 10, 180, 180, "0x0700" )
GUISetState( @SW_SHOW )

While $read = True    
    _FileReadToArray( $s_FileName, $a_Lines )

    $i_tailLines = 5

    $a_Tail = _Tail( $i_tailLines, $a_Lines )

#    _ArrayDisplay( $a_Tail, "" )
    
    $msg = GUIGetMsg()
    
    If $msg = $GUI_EVENT_CLOSE Or $msg = $stop Then
        $read = False
    EndIf
WEnd

Func _Tail( $i_numTail, $a_readLines )
    #calculate which line to end on
    $endLine = UBound( $a_readLines ) - $i_numTail
    
    Dim $a_tailLines[ $i_numTail ]
        
    For $iter = UBound( $a_readLines ) - 1 To $endLine Step -1
        $a_tailLines[ $iter - $endLine ] = $a_readLines[ $iter ]
    Next
    
    Return $a_tailLines        
EndFunc

Hope this helps.

Thanks for the effort, but i get the following error when i try to beta compile it:

(36) : ==> Array variable subscript badly formatted.: 
$a_tailLines[ $iter - $endLine ] = $a_readLines[ $iter ] 
$a_tailLines[ $iter - $endLine ] = $a_readLines[ ^ ERROR

I'm wondering, what version of Autoit Beta are you using (i'm using the latest, 133 i think it is).

Forgot to warn you, this reads from "test.txt" and includes NO ERROR CHECKING. Please make sure you have a test.txt file in the script dir or you change the file name in the script to some file in the script dir. This is whats causign the error.

Yes I saw that. i do have the test.txt file on the same folder as the script.

I'll post it in scripts and scraps when im done cleaning it up and optimizing it.
