jacQues Posted February 13, 2008 Share Posted February 13, 2008 In the latest beta you can use -1 as last parameter on FileReadLine function... - Added: FileReadLine( ,-1) read last line. Nice, but will that read the last line if there's no @LF? The problem I have it that the following code: $fil = FileOpen("notes.txt",0) DO $lin = FileReadLine($fil) $err = @error $lin = StringStripWS($lin,7) IF ... THEN ... do stuff ENDIF UNTIL NOT ($err==0) Reads the entire file but not the last line if the file 'simply ends' and doesn't have a @LF or @CR or EOF. jacQues Link to comment Share on other sites More sharing options...
jokke Posted February 13, 2008 Share Posted February 13, 2008 Or you can use a function that is allready made for this. Just create a test.txt file with a few lines of text. #include <file.au3> $file = "test.txt" $CountLines = _FileCountLines($file) If $CountLines = 0 Then ConsoleWrite("Either file is empty or no file found."&@CRLF) Else ConsoleWrite(FileReadLine($file,$CountLines)&@CRLF) EndIf UDF:Crypter a file encrypt / decrypt tool with no need to remember a password again.

jacQues Posted February 13, 2008 Share Posted February 13, 2008 Your solution doesn't work. Not sure why I did the following: #include <file.au3> MsgBox(0,"test",_FileCountLines($file)) Result: -21316 Ehhhhh.....? jacQues Link to comment Share on other sites More sharing options...
jacQues Posted February 13, 2008 Share Posted February 13, 2008 Got it working now. Thanks for helping out. _FileCountLines didn't work because it assumes @LF, but my notes.txt file uses @CRLF. Got a workaround using StringLen($file)-StringLen(StringReplace($file,@CRLF," ")) jacQues Link to comment Share on other sites More sharing options...
