Error allocating memory - filewriteline [SOLVED]

[ahha]

It took a month of cutting down a big program to find it and here's the code to illustrate "Error allocating memory".

The first while using the filename in the fileopen, etc. shows the error.  The second while example does not have the problem (so I switched to using it).

expandcollapse popup

;shows "Error allocating memory"
;Autoit v3.3.14.5

#AutoIt3Wrapper_run_debug_mode=Y    ; use this to debug in console window <--- LOOK

#include <FileConstants.au3>


;--- shows error allocating memory - is it Autoit or SciTE ?  Try compiling <-- makes no difference so probably not SciTE.  Normally error at index 50K-100K

$fnINDEX = @ScriptDir & "\__index.txt"
$i = 0

;#cs
While 1
    $i = $i + 1
    FileOpen($fnINDEX,  $FO_OVERWRITE)  ;overwrite as we just need last one processed
    FileWriteLine($fnINDEX, $i)
    FileClose($fnINDEX)

    If $i/1000 = Int($i/1000) Then MsgBox(0, "count", "$i = " & $i, 1)  ;give indication of count, hangs when memory allocation error imminent
WEnd
;#ce

;comment out the above loop and this works without an allocation error - looks like the above code leaking memory?

While 1
    $i = $i + 1
    $fh = FileOpen($fnINDEX,  $FO_OVERWRITE)    ;overwrite as we just need last one processed
    FileWriteLine($fh, $i)
    FileClose($fh)

    If $i/1000 = Int($i/1000) Then MsgBox(0, "count", "$i = " & $i, 1)  ;give indication of count
WEnd


Exit    ;program

Try this change.

While 1
    $i = $i + 1
    $hFile = FileOpen($fnINDEX, $FO_OVERWRITE) ;overwrite as we just need last one processed
    FileWriteLine($hFile, $i)
    FileClose($hFile)

    If $i / 1000 = Int($i / 1000) Then MsgBox(0, "count", "$i = " & $i, 1) ;give indication of count, hangs when memory allocation error imminent
WEnd

The way you wrote it you were leaving open file handles after every loop through. FileClose needs a HANDLE and not a file name. Also, the way you wrote it, there's no need for a FileOpen or FileClose because you never used the handle returned by the FileOpen.

It'll be great when I learn to read.  You are correct in Remarks "The file handle must be closed with the FileClose() function."

Thanks
