Array Functions

[jezzzzy]

This function only produces 3 lines of the text file. Not sure why.

Func LoadFile()
    If Not _FileReadToArray($filepath & GUICtrlRead($dropdown),$listviewcontents) Then
        GUICtrlCreateListViewItem("Error reading log file.",$listview)
    EndIf
    ;MsgBox(0,"ArraySize",$listviewcontents[0])
    For $x = 1 to $listviewcontents[0]
        GUICtrlCreateListViewItem($listviewcontents[$x],$listview)
    Next

Update:

I thought I would run through my problem again, the way that anyone trying to assist me might. So I copied the text that I posted and made a new text file with it. Then ran my script and it returned everything correctly. So that would indicate that my text file is weird. I am posting the file that I am working with so that someone could at least duplicate my problem.

syslog.2008.06.11.txt

is the original file saved as unicode?

If you open the original file and do a Save as you should see in the encoding section what it says it is saving as

[jezzzzy]

Notepad shows ANSI in the 'Save As...' dialog. Also, I have attached the file earlier this thread if it helps.

But you say the actual file contains 1178 lines, the one you posted only contains 17 so it is not the original file is it?

I just tried your attached logfile and _filereadtoarray does screw it up

I think the best way is to do it manually yourself like this example I have done for you..

expandcollapse popup

#include <guiConstants.au3>


Local $fileArray[1];declare the array

;open the file with a file handle as it is quicker to read lots of lines
$file = FileOpen("syslog.2008.06.11.txt", 0)

; Check if file opened for reading OK
If $file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf

; Read in lines of text until the EOF is reached
While 1
    $line = FileReadLine($file)
    If @error = -1 Then ExitLoop
    
    Redim $fileArray[Ubound($fileArray) + 1];increase the size of the array to accomodate the new value
    $fileArray[Ubound($fileArray) - 1] = $line; add the new value to the end of the array
    
Wend

    $fileArray[0] = Ubound($fileArray);set array[0] value to the total number of elements in the array

;close the file handle
FileClose($file)




_ArrayDisplay2($fileArray);display the results


Func _ArrayDisplay2(Const ByRef $avArray, $sTitle = "");my modified arraydisplay in a listview (work in progress!)
    
    If (Not IsArray($avArray)) Then
        SetError(1)
        Return 0
    EndIf
    
    Local $iRows = 0, $iCols = 0, $cHeaders, $iCnt = 0, $lv ,$lCnt = 0, $tCnt = 0, $rtext, $cButton,$lvGui,$lvGuiMsg

    $iRows = Ubound($avArray) -1
    $icols = Ubound($avArray,2)
    
    $cHeaders = "I/C |0|"
    
    For $iCnt = 1 to $iCols -1
        $cHeaders &= $iCnt & "|"
    Next
    
    $lvGui = GuiCreate($sTitle,400,300)
    $lv= GuiCtrlCreateListview($cHeaders,20,20,360,220)
    
If $icols <> 0 then 
    
    For $lCnt = 0 to $iRows
        $rtext = "[" & $lCnt &"]|"
        For $tCnt = 0 to $icols -1
            $rText &= $avArray[ $lcnt][$tcnt] & "|"
        Next
        GUICtrlCreateListViewItem($rText,$lv)
    Next
    
Else
    
    For $lCnt = 0 to $iRows
        $rtext = "[" & $lCnt &"]|" & $avArray[$lCnt]
        GUICtrlCreateListViewItem($rText,$lv)
    Next
    
    
EndIf


$cButton = GuiCtrlCreateButton("Close", 150, 260, 110, 30)


GuiSetState()

While 1
    $lvGuiMsg = GuiGetMsg(1)
    Select
        Case $lvGuiMsg[0] = $GUI_EVENT_CLOSE or $lvGuiMsg[0] = $cButton
        If $lvGuiMsg[1] = $lvGui then ExitLoop
        
        Case Else
        ;;;
    EndSelect
WEnd
    
    SetError(0)
    Return 1

EndFunc

I just tried your attached logfile and _filereadtoarray does screw it up

The file contains a Null character after the end of the first record: 0D 0A 00 Edited April 24, 2007 by JdeB

[jezzzzy]

Thank you much. The manual method works.

Edit:

Just read JdeB's post. Is it wise to search the entire text file for null value's or will that generate a significant lag? I would obviously rather use the built-in functions than create a custom function for all of the file to array tasks.

Edited April 24, 2007 by jezzzzy

[jezzzzy]

I thought I remembered seeing a post on getting rid of NULL values from strings but now I can't find it. Doesn't look like I can just use StringReplace() to get rid of NULL values.

Actually, the content before the null value is not needed. In fact, I strip it out anyway in my For...Next loop. Is there a way to StringInStr() for a NULL value?

You can still do it with included functions, you can read each line like I did and if you #include <Array.au3> you could use _ArrayAdd() to build your array although it pretty much does what I did but in an included function.

Infact jdeb who replied earlier created the original UDF!

Try this script with the current Production and Beta versions..

I don't think the current Beta handles the hex 00 correctly:

#include<file.au3>
#include<array.au3>

_FileReadToArray("syslog.2008.06.11.txt",$aTest)
_ArrayDisplay($aTest,"test")

Thank you very much Jdeb. Switching from the Beta fixed all of my issues.
