CPU intensive Script (HELP!)

Recommended Posts


Hello peeps! once again i seek aid from you find chaps.

So i have made a Download manager as best to my ability, keeping it as simple as possible for my users whilst still trying to be functional. So what i wanted to do was create this download manager so the user could enter about 10 links at a time (each file could be upto 200mb's) and then the script would then re-open itself for each link given so if 10 links were entered then 10 new instances of my script would be opened, each downloading a single file. I did it this way because INetGet can only be run one at a time (which sucks).

Now obviously my problem is when running 10 or so .exe files is very CPU intensive!!! Now i either need to cut down my script CPU usage or do a complete rebuild of my app.

Heres my code:

#include <GUIConstantsEx.au3>
#include <GuiStatusBar.au3>
#include <WindowsConstants.au3>
#include <StaticConstants.au3>
#include <ProgressConstants.au3>
#include <EditConstants.au3>

Opt("GUIOnEventMode", 1)
If $CmdLine[0] > 0 Then
    _RunDownloader($CmdLine[1], $CmdLine[2], $CmdLine[3], $CmdLine[4])

Dim $staMainParts[2] = [150, 250]
Const $IniFile = @AppDataDir & "\" & "RapidLoad.ini"
Global $X = 5, $Y = 5
$winMain = GUICreate("Rapidshare Downloader", 627, 325, -1, -1)
$txtLinks = GUICtrlCreateEdit("", 8, 66, 609, 201)
$Label1 = GUICtrlCreateLabel("Enter Links Below:", 9, 48, 92, 17)
$staMain = _GUICtrlStatusBar_Create($winMain)
    _GUICtrlStatusBar_SetParts($staMain, $staMainParts)
    _GUICtrlStatusBar_SetText($staMain, "Account: 106545", 0)
    _GUICtrlStatusBar_SetText($staMain, "Status: Active", 1)
$btnDownload = GUICtrlCreateButton("Download!", 528, 272, 91, 25, 0)
$txtSaveTo = GUICtrlCreateInput(@HomeDrive & "\", 8, 24, 529, 21, BitOR($ES_AUTOHSCROLL,$ES_READONLY))
$btnBrowse = GUICtrlCreateButton("Browse", 544, 22, 75, 25, 0)
$Label2 = GUICtrlCreateLabel("Save Location", 9, 6, 73, 17)
GUISetState(@SW_SHOW, $winMain)

GUICtrlSetData($txtSaveTo, IniRead($IniFile, "Settings", "SaveTo", @HomeDrive & "\"))

GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit", $winMain)
GUICtrlSetOnEvent($btnBrowse, "_ChangeSaveTo")
GuiCtrlSetOnEvent($btnDownload, "_Download")

While 1

Func _RunDownloader($Link, $SaveTo, $X, $Y)
    Dim $StaMainParts[3] = [50, 150, 150]
    Dim $Size = InetGetSize($Link)
    Dim $Bytes, $NewBytes, $BytesLeft, $N
    Global $Name = _GetName($Link)
    $winDownload = GUICreate("RapidLoader", 289, 83, $X, $Y, -1, $WS_EX_TOOLWINDOW)
    $prgDownload = GUICtrlCreateProgress(8, 32, 270, 17)
    $staMain = _GUICtrlStatusBar_Create($winDownload)
        _GUICtrlStatusBar_SetParts($staMain, $staMainParts)
        _GUICtrlStatusBar_SetText($staMain, "0%", 0)
        _GUICtrlStatusBar_SetText($staMain, "Speed: 0kb/s", 1)
        _GUICtrlStatusBar_SetText($staMain, "0 Megabytes Remaining", 2)
    $Label1 = GUICtrlCreateLabel("Downloading: ", 8, 8, 72, 17)
    $labName = GUICtrlCreateLabel($Name, 78, 8, -1, -1)
    GUISetOnEvent($GUI_EVENT_CLOSE, "_DownloadExit")
    InetGet($Link, $SaveTo & "\" & $Name, 1, 1)
    While @InetGetActive
        $BytesLeft = $Size - @InetGetBytesRead
        $Bytes = Round(@InetGetBytesRead)
        $NewBytes = Round(@InetGetBytesRead)
        $Percent = StringLeft(@InetGetBytesRead / $Size * 100, 4)
        GUICtrlSetData($prgDownload, $Percent)
        _GUICtrlStatusBar_SetParts($staMain, $staMainParts)
        _GUICtrlStatusBar_SetText($staMain, $Percent & "%", 0)
        _GUICtrlStatusBar_SetText($staMain, "Speed: " & ($NewBytes - $Bytes) /1024 & "kb/s", 1)
        _GUICtrlStatusBar_SetText($staMain, Int($BytesLeft / 1048576) & " Megabytes Remaining", 2)
    $N = MsgBox(68, "Download Complete", "The download of: " & @CRLF & $Name & @CRLF & "Has completed. Do you wish to open the file?")
    If $N = 6 Then
        ShellExecute($SaveTo & "\" & $Name)

Func _Download()
    Dim $Text = GUICtrlRead($txtLinks)
    If $Text = "" Then
        MSgBox(48, "Error", "You did not enter any links!")
        Dim $Links = StringSplit($Text, @CR)
        For $I = 1 To Ubound($Links) -1

Func _StartDownload($Link)
    ShellExecute(@ScriptFullPath, $Link & ' "' & GUICtrlRead($txtSaveTo) & '" ' & $X & " " & $Y)
    If ($Y + 220) > @DesktopHeight Then
        $X += 300
        $Y = 5
        $Y += 110

Func _ChangeSaveTo()
    Dim $eFile = FileSelectFolder("Save files to...", "*", 7, @HomeDrive)
    If $eFile > "" Then
        GUICtrlSetData($txtSaveTo, $eFile)

Func _GetName($Link)
    Dim $N = StringSplit($Link, "/")
    Return $N[Ubound($N)-1]

Func _DownloadExit()
    Dim $N = MSgBox(36, "Cancel Download", 'Are you sure you want to cancel the download of "' & $Name & '" ?')
    If $N = 6 Then

Func _Exit()
    IniWrite($IniFile, "Settings", "SaveTo", GUICtrlRead($txtSaveTo))

If you look at the RunDownloader function i have a 7 second sleep time in my While loop. This cuts down the CPU usage but 7 seconds to update the KB/s sucks =(

Any ideas would be awesome.

didnt work =( one window takes up 50% of CPU

If I run your script it uses 50% of CPU time as you say.

If I put Sleep(50) in the while/wend loop it goes down to less than 1% (ie it shows 0)

...the other loop

Why running 10 instances? Run one and load it with 10 scripts using "/AutoIt3ExecuteScript" (actually one but with 10 different parameters).


though running another script is another instance

/AutoIt3ExecuteScript requires autoit to be installed though and i want my app to be independent.

A compiled Au3 exe has the /AutoIt3ExecuteScript ability also.

Your.exe /AutoIt3ExecuteScript <Autoit script (au3/a3x)>
