For this i have to check whether the logfile is empty. how can i do this?

Hi,

this should get the goal:

$logfile = "c:\mylog.txt"
$string = FileRead ($logfile)
If $string = "" Then
    MsgBox (0,"","Log empty!")
Else
    MsgBox (0,"Content of Log",$string)
EndIf

;-))

I would extend the example a little bit. Only read one byte so you don't heave to read a multi-megabyte-file if the log exists.

$logfile = "c:\mylog.txt"
$string = FileRead($logfile,1)
If $string = "" Then
 MsgBox (0,"","Log empty!")
EndIf

Hi all,

What is wrong with FileGetSize? ;)

If FileGetSize("c:\mylog.txt") = 0 Then MsgBox (0,"","Log empty!")
