Loops, Progress, multiple file downloads, cancel gui problem

AJStevens · August 11, 2010

Hi all, I've searched through the forum, done Autoit 123, read the helpfile, tried various examples and I'm even studying the AutoUpdateIt.au3 carefully, however I would really appreciate some help from someone, none of these examples involve multiple downloads, the ones that do, don't have a cancellation option.

I "think" the issue is because, to do multiple downloads, one after the other in a Progress and Overall Progress way requires a loop, but the program is then stuck in that loop and unable to process any GUI operations until that loop is completed, whether in "Msg Mode" or OnEventMode it seems.

I'm having trouble getting my head around this one, and could really use a small example I can incorporate or rewrite my code based on, it's already got wildly out of control.

Multiple downloads (from a 2 dimensional array)

GUI with Progress bar and a overal progress bar

Cancel button that works while downloading

I would prefer OnEventMode version preferably, it makes more sense to me, but any or both would be fantastic.

I know this sounds really newbish, but I'm sure if I can just get help with this primary concept, I'll be off and away with AutoIT.

From the helpfile:

Remarks

Internet Explorer 3 or greater must be installed for this function to work.

The URL parameter should be in the form "http://www.somesite.com/path/file.html" - just like an address you would type into your web browser.

To use a username and password when connecting simply prefix the servername with "username:password@", e.g.

"http://myuser:mypassword@www.somesite.com"

Notes about the "background" Parameter

By default the function waits until the download has finished before returning. If the background parameter is set to 1 the function returns immediately and the download continues in the background. The function InetGetInfo() can be used to check the status of the download. It takes the handle returned from InetGet().

Multiple downloads are supported if they are started in background mode.

To abort a download call InetClose() and pass it the handle returned by InetGet().

By default AutoIt forces a connection before starting a download. For dial-up users this will prompt to go online or dial the modem (depending on how the system is configured). The options value 16 disables this behavior. Disabling the behavior can be useful for persistent connects (Broadband, LAN). However, it is also required to work around certain issues in Windows Vista and Windows 7.

MPH, yeah I did read that in the helpfile, as I said.

However my issue is when you're trying to combine it all with multiple downloads (processing through an array of them), with a progress bar and and overall progress bar in a GUI, but still being able to press a cancel button that will use InetClose() to cancel the download.

Bert · August 11, 2010

Here is the thing - AutoIt is single thread, not multi thread. You may need to start up a separate process for each download.

If you use a cancel button, how are you going to choose which one is going to be cancelled? Or are you planning on cancelling them all?

Here is the thing - AutoIt is single thread, not multi thread. You may need to start up a separate process for each download.

Actually it's not that hard. I've written something like this before, Let me see if I can find it.

FlyinRiz · August 11, 2010

Actually it's not that hard. I've written something like this before, Let me see if I can find it.

I've actually done something like this before to get around the Beep's Asynchronous limitation in AutoIt. It could proabably be easily modified for downloading files...you just need two files (the master program and the helper or secondary program) The master program would call the secondary with a parameter...

Master

Run(@ScriptDir & "\tone.exe " & $Hz)

Secondary (tone.exe)

If $CmdLine[0] <> 1 Then
    Exit
EndIf

Global $Hz = $CmdLine[1]
;...and so on...

You could use the StdIn/Out functions for communicating to the Child for info on file progress and save the PIDs for closing/cancelling the downloads. Hope all of this helps.

Here is an example of how this could work in a single process. There is still enough for you to do, but it should get you on your way.

#include <array.au3>
Global $aDownloads[1]
Global $aProgress[1]
Global $aButtons[1]
Global $aSize[1]

Opt("GuiOnEventMode",1)
Global $mainGUI = GUICreate("MultiDownload",470,40)
GUISetOnEvent(-3,"_Exit")
$ctrlAdress = GUICtrlCreateInput("",10,10,380)
GUICtrlSetResizing(-1,802) ;dockall
GUICtrlCreateButton("Download",400,10,60,20)
GUICtrlSetResizing(-1,802) ;dockall
GUICtrlSetOnEvent(-1,"_AddDownload")
GUISetState()

While 1
    Sleep(100)
    For $i = 1 To UBound($aDownloads) -1
        $Progress = InetGetInfo($aDownloads[$i],0)
        If $aSize[$i] Then
            GUICtrlSetData($aProgress[$i],($Progress/$aSize[$i])*100)
        Else
            GUICtrlSetData($aProgress[$i],50)
        EndIf
    Next
WEnd

Func _AddDownload()
    Local $sUrl = GUICtrlRead($ctrlAdress)
    Local $sPath = StringInStr($sUrl,"/",0,-1)
    $sPath = @ScriptDir & "\" & StringTrimLeft($sUrl,$sPath)
    ConsoleWrite("Saving : " & $sUrl & @CRLF & "To: " & $sPath & @CRLF)
    Local $Index = _ArrayAdd($aDownloads,InetGet($sUrl,$sPath,0,1))
    WinMove($mainGUI,"",Default,Default,Default,30*$Index + 60)
    _ArrayAdd($aProgress,GUICtrlCreateProgress(10,30*$Index+5,380))
    GUICtrlSetResizing(-1,802) ;dockall
    _ArrayAdd($aButtons,GUICtrlCreateButton("Cancel",400,30*$Index+5,60))
    GUICtrlSetOnEvent(-1,"_CancelDownload")
    GUICtrlSetResizing(-1,802) ;dockall
    _ArrayAdd($aSize,InetGetSize($sUrl))
EndFunc

Func _CancelDownload()
    Local $Index = _ArraySearch($aButtons,@GUI_CtrlId)
    InetClose($aDownloads[$Index])
EndFunc

Func _Exit()
    Exit
EndFunc

suggested improvements:

Cancel button should become an Open file button

Better solution for files with unknown size (currently shows 50% complete)

Complete downloads should be removed from the arrays

Better sulution for identical filenames (currently it overwrites without prompt)

many more.

edit:

Stop downloads before exit!!!

edit2:

fixed the cancel buttons :blink:

Thanks very much for the replies, your help is very much appreciated.

Yeah, so I've noticed, but it's only doing one download at a time, I think it's just structuring the loops properly, and my head is spinning reading bits here and there and not a "full picture".

If you use a cancel button, how are you going to choose which one is going to be cancelled? Or are you planning on cancelling them all?

-Aaron

Just to be clear, the downloads are processed one after another, not simultaneously, and the cancel button is to firstly cancel the current download in progress and break out of the loop and not process any others left to do.

Tvern, looked at your example, interesting... but I think like Aaron you've gone down the simultaneous route.

Basically, I've generated an array of downloads (using a process to discover these I won't bore you with), I then hope to download each of these one after the other, showing a progress bar (also showing bytes, but I can do that), and below it an "Overall Progress" (based on current commulative bytes downloaded and total size of all downloads). Oh and updating a status label with "Downloading... <filename>".

To do this I go through a For Loop for the downloads, and then inside that a Do...Until to update the progress display.

GUI:

Status Label (eg. "Downloading... <filename>"

- Current File Progress Bar -

- Overall Progress Bar -

[ Download ] [ Cancel ]

2DM Array of downloads:

$downloads =

Row Col0 Col1 etc.

[0][4]

* This is a label and not an accurate filesize, eg. "24 MB"

** Product name, without any version number in the name, eg. "Internet Explorer" not "Internet Explorer 8"

Example:

[1]|Microsoft Internet Explorer|Web Browser|8.0.6001.18702|32 MB|http://download.microsoft.com/internetexplorer.exe|Internet Explorer|8|33554432|iesetup.exe|C:\Temp\iesetup.exe|0

Some of that information is used to display progress (I like to show bytes process as well as percentage), and some is for information display in like a listview for the user to see what it's picked to download, and the obvious URL and Local path needed for a InetGet and a FileMove for the actual download.

Problem is, while it's processing the For..Next (downloads in the array) and inside that the Do...Until (file downloaded) the cancel won't work, it queues and waits.

I hope that's clearer.

Right. let me see if I can make an example script.

Right. let me see if I can make an example script.

Excellent, thank you.

I found the script I originally based the download/update portion of mine off of. I quickly edited it to OnEventMode instead of MessageLoop, and altered the GUI, it's much simplier than what my code has turned into, there's no bytes progress, or the code to generate the download array, though there is one here, much simplier than the one mine became or the rubbish I put in there to try to get cancel to work etc. but easier to work with I think. If the cancel button can be made to work here, then I can get it to work in my code (after a complete rewrite most likely).

I think your cancel button doesn't work because an Event will not interrupt a function called by another event, or something like that, but someone with more knowledge of the way autoit works would have to confirm that. (the events are queue'd and run one after the other)

I think this quick hack might back up my theory

Tvern, that's great, thanks that works.

However, trying to put it into my own code... it's still not having it.

I thought it might have been because I call a function from within the function, so I tried a basic nest, no problem there.

I thought it might be because I'm reusing buttons (turning Check into Cancel, then into Download, then into Cancel again), so implemented those bits into that example and it still works.

So... I'm building a second script, moving in a piece at a time, trying to see where I've gone wrong... I've now got everything in there, except the Download function (still doing the cutepdf test downloads).

Either I'll figure it out, or will have written a new script and chalk it upto some minute oversight somewhere in my original script.

I'll post again after integrating the slightly enhanced download function, hopefully it'll still be working.

When you run into unexpected behavior like this it often helps to make the program report what it is doing.

Adding trace lines (from the tools menu in Scite if you have the full package), or using the debug console can help with this.

NiVZ · August 13, 2010

Excellent, thank you.

I found the script I originally based the download/update portion of mine off of. I quickly edited it to OnEventMode instead of MessageLoop, and altered the GUI, it's much simplier than what my code has turned into, there's no bytes progress, or the code to generate the download array, though there is one here, much simplier than the one mine became or the rubbish I put in there to try to get cancel to work etc. but easier to work with I think. If the cancel button can be made to work here, then I can get it to work in my code (after a complete rewrite most likely).

Haha thought that _Download() code looked familiar, I'd recognise those comments anywhere

This is possible to do - I've got another program which does multiple downloads sequentially (one after the other) from an Array and you can cancel it.

I think I had to change it back out of GUIOnEventMode while it's doing the downloads.

EDIT: Just saw your post in my original thread - yes you can make a progress bar for when it's getting the filesizes too. If I get a chance I'll see if I can put something together.

Hello,

I found one that was very close so put it into the previous example. This one has a cancel button (plus a confirm cancel) and it shows a progress bar while getting filesizes (just used progresson function for quickness)

Only thing it doesn't do is reset the gui if you cancel - wasn't sure what you wanted to do if they cancel. It should get you on your way though.

For the Kb/Mb/Gb etc you need to use InetGetInfo($Download, 0) to get the bytes transferred and then just do a calculation (ie if it's less than 1024 use bytes, less than 1024*1024 use kB, less than 1024*1024*1024 use Mb, etc), and if you want average data transfer rate, use TimerInit before you start the download and then divide the amount you've downloaded by the time it's taken (you can also use that to give an estimated time remaining - in Microsoft minutes!)

When you run into unexpected behavior like this it often helps to make the program report what it is doing.
Adding trace lines (from the tools menu in Scite if you have the full package), or using the debug console can help with this.

Yep, I've got Console("Debug: " & "Notes" & $val & @CRLF) or MsgBox all over the place... wish I had a key to just paste that in on the line I'm on and a Tidy option to find them all and remove before compiling (I usually forget one somewhere.

Haha thought that _Download() code looked familiar, I'd recognise those comments anywhere
This is possible to do - I've got another program which does multiple downloads sequentially (one after the other) from an Array and you can cancel it.
I think I had to change it back out of GUIOnEventMode while it's doing the downloads.
EDIT: Just saw your post in my original thread - yes you can make a progress bar for when it's getting the filesizes too. If I get a chance I'll see if I can put something together.

Hi NiVZ, yeah excellent example, helped me alot, I managed to achieve this finally (I think, some testing to do.. yesterday it was locking up doing a lot of filesize checks, for say downloading 30 files). Fortunately, I'm able to use GUIOnEventMode all the time.

I have percent labels, but the progress bars operate on the filesizes, I thought that would be better.

Hello,
I found one that was very close so put it into the previous example. This one has a cancel button (plus a confirm cancel) and it shows a progress bar while getting filesizes (just used progresson function for quickness)
Only thing it doesn't do is reset the gui if you cancel - wasn't sure what you wanted to do if they cancel. It should get you on your way though.
For the Kb/Mb/Gb etc you need to use InetGetInfo($Download, 0) to get the bytes transferred and then just do a calculation (ie if it's less than 1024 use bytes, less than 1024*1024 use kB, less than 1024*1024*1024 use Mb, etc), and if you want average data transfer rate, use TimerInit before you start the download and then divide the amount you've downloaded by the time it's taken (you can also use that to give an estimated time remaining - in Microsoft minutes!)

Cool, still a very useful example that should be in the helpfile I think.

Mine resets, after a couple of seconds sleep, just so the user can see what happened.

Yep, done that, it also helps "decide" on the label, eg. KB, MB, GB as it increases.

Hmm.. transfer rate... hadn't thought about that... and Microsoft minutes estimated time... I might add that if it's desired, but seeing the data and percent progress is probably enough, lol. I'll have to read up on TimerInit, not used it yet.

I also had to do some registry work to get around the new behaviour for IE with username:password in URLS... what fun, this forum is an excellent resource.
