#1831 closed Bug (Fixed)

_FileCountLines does not handles null characters

Reported by: Fabien OBRIER <fobrier@…> Owned by:
Milestone: Component: AutoIt
Version: Severity: None
Keywords: file.au3 _FileCountLines Cc:


When using _FileCountLines on a text file containing some NULL (=Chr(0)) the function does not report the whole number of lines.
The function only return the number of lines before the first NULL character.

To avoid this, I propose to include a StrinReplace to delete the NULL characters as below:

Func _FileCountLines($sFilePath)

	Local $hFile = FileOpen($sFilePath, $FO_READ)
	If $hFile = -1 Then Return SetError(1, 0, 0)
	Local $sFileContent = StringStripWS(StringReplace(FileRead($hFile), Chr(0), ""), 2) ;****here is the modified line****
	msgbox(0, "", $sFileContent)
	Local $aTmp
	If StringInStr($sFileContent, @LF) Then
		$aTmp = StringSplit(StringStripCR($sFileContent), @LF)
	ElseIf StringInStr($sFileContent, @CR) Then
		$aTmp = StringSplit($sFileContent, @CR)
		If StringLen($sFileContent) Then
			Return 1
			Return SetError(2, 0, 0)
	Return $aTmp[0]

Best regards,

Oups! In the script please ignore the line:

msgbox(0, "", $sFileContent)

Problem is in the StringStripCR() function. Its clipping strings at the NUL-character. See ticket #1832
