[SOLVED] why won't this simple Logger work?

[MonsieurOUXX]

this is my code :

============= FILE : logging.au3 ===========
 
#Include <Date.au3>
 
 
func LogMsg($msg)
    $fileName = "log.txt"
    $file = FileOpen($fileName, 1)
    if $file = -1 Then
        MsgBox(0, "Error", "could not open file " & $fileName)
        Exit
    EndIf
    
    FileWriteLine($file, _Date_Time_GetSystemTime() & " : " & $msg)
    FileFlush ($file)
    FileClose($file)        
    
endFunc
 
============= FILE: mytest.au3 =============
 
#include "logging.au3"
 
LogMsg("this is a test")

As you can see it's very basic and very straightforward.

Yet, after I execute "mytest.au3" in SciTE, the file "log.txt" exists but remains desperately empty...

I'm on Windows 7 with a Symantec antivirus

Basic support question that should have been in General Help and Support (It's now moved there). I don't think you understand what _Date_Time_GetSystemTime() actually returns.

[sleepydvdr]

#include <GuiConstantsEx.au3>
#include <Date.au3>
#include <WindowsConstants.au3>

 LogMsg("this is a test")

func LogMsg($msg)
    $fileName = "log.txt"
    $file = FileOpen($fileName, 1)
    if $file = -1 Then
        MsgBox(0, "Error", "could not open file " & $fileName)
        Exit
    EndIf
    $tDate = _Date_Time_GetSystemTime()
    FileWriteLine($file, _Date_Time_SystemTimeToDateStr($tDate) & " : " & $msg)
    FileFlush ($file)
    FileClose($file)

endFunc

Sorry about posting to the wrong forum! I'm pretty much new around here ( I was around some time ago but since then I lost all my good habits ). My apologies again.

And both of you are absolutely right: I added "_Date_Time_GetSystemTime()" in a rush at the very end and trusted the name without checking the specs. I was so focused on the file management that I forgot to double-check that, thinking "oh, whatever it outputs I'll have time later to correct it and format it better". Shame on me!

Thank you so much, guys/ladies.

EDIT: Actually it doesn't change anything, the problem remains....

BUMP.

Even with that change, the file remains empty...

EDIT :

OH WAIT that's actually hilarious (well, from my perspective it is).

The issue was simply that since my early tests there were hundreds of blank lines at the beginning of the file.

All I had to do was... to scroll down.

And if you think I'm retarded, well have a look at Windows 7's theme, where everything is pale gray and where nothing catches the eye (ninja scrollbars...)

The code I gave you works for me. But there is an easier way:

#Include <File.au3>
_FileWriteLog("Log.txt", "This is a test.")

See my update above

All my apologies, really.
