FileWrite returns buggy ?

[Inverted]

I've discovered this problem/bug (?) in a bigger project, I've narrowed it down to this simple testcase :

$progname = "File_patcher"
$targetfilename = "222.exe"
$newbytes    = "738878378387348773487348734783478348743874373878335"

$f_handle = FileOpen($targetfilename,16+2)
FileWrite($f_handle, $newbytes)
If @error = 0 Then
    MsgBox (16, $progname, "Error writing file")
Else
    MsgBox (4096, $progname, "File successfully written !")
EndIf
FileClose($f_handle)

FileWrite always returns @error = 0 , even when the operation succeeds !! Tested on Vista 32, file 222.exe is created or overwritten with my data. Successful but @error =0 returned, right ?

you seem to be confused with the returncode and @error:

$rc = FileWrite($f_handle, $newbytes)
If $rc = 0 Then
    MsgBox (16, $progname, "Error writing file")
Else
    MsgBox (4096, $progname, "File successfully written !")
EndIf

When you look at things from different perspective(s), you have very interesting nick.

What would you expect to be returned?

Aha, I was looking at the FileOpen returns and got mixed up with @error as well, tsk tsk ....
