Dllcall syntax Error?

[Danyfirex]

Hi mates, I'm trying to make a LOF "len of file" function but I can't make it work. I don't know what's the problem.

this is my code.

$file="C:\Users\Usuario\Desktop\1.txt"
local $a
$handle=dllcall("kernel32.dll","int","lopen","HANDLE",$file,"str",0)
$size= Dllcall("kernel32.dll","int","GetFileSize","str",$handle,"DWORD*",$a)
dllcall("kernel32.dll","int","lclose","str",$handle)
msgbox(0,"",$size[2])

I don`t find any help about lopen and lclose parameters.

This line:

$handle=dllcall("kernel32.dll","int","lopen","HANDLE",$file,"str",0)

What is this 'lopen' function? never heard of it before.

Also, in that line of code, you have a string which represents the file to open ($file) but your converting it to a handle ... That doesnt make any sense.

$sFile = 'C:UsersUsuarioDesktop1.txt'
$hFile = DllCall('kernel32.dll', 'ptr', 'CreateFileW', 'wstr', $sFile, 'dword', 0x80000000, 'dword', 0x06, 'ptr', 0, 'dword', 3, 'dword', 0, 'ptr', 0)
$Ret = DllCall('kernel32.dll', 'int', 'GetFileSizeEx', 'ptr', $hFile[0], 'uint64*', 0)
DllCall('kernel32.dll', 'int', 'CloseHandle', 'ptr', $hFile[0])

ConsoleWrite($Ret[2] & ' bytes' & @CR)

I didn't find any help about lopen. Only a code in other lenguage, I was traslating to Autoit.

Yashied thank you so much for helping me and the script.
