catching downloads in an IE object

13 posts in this topic

A while back, I wrote a script which went to ninite.com, selected the checkboxes for the applications needed for os deployment, and submitted the form.  Back then, to start the download, I simply had script lock user input, sleep for 5 seconds to wait for download prompt to appear, used Send to press tab and enter on "run" for download prompt, then unlock user input.  However, I am working on another project now which requires a bit more...assurance.  Basically, the problems with the method on the last problem had many issues: 1) since it was for os deployments, usually when the script was run, the Internet explorer first run windows kept getting in the way, requiring me to create a completely arbitrary function to call before the main function which would open IE, wait, then force end it to get rid of prompt, 2) I lock the user input since the success of the process is dependent on where the caret position is in the IE window, and users just love to mess with stuff.  But this creates the draw back that, heaven forbid, something in the background of the users computer could cause IE to lose focus in one way or another, which results in the download failing and script is not successful.  So, on to main question.  For those who have used ninite, you know already that the executable is not at a set URL, it is generated depending on the checkboxes the user selects for the applications they want installed, so I can't just use Inetget.  Is there a way that I can "hook" or get a handle to the object which facilitates downloads in IE?  Thanks in advance.

Hi MattHiggs,

I do not know if I got right your intent (not a native english), but you can monitor the "BeforeNavigate" event then read urls (take any action if you want to) and use the "DownloadBegin" and "DownloadComplete" events to make a proper check. There is an exemple in the helpfile under the "ObjEvent" function that shows how to use the "BeforeNavigate2" event.

Ok.  So from what I understand, you seem to think I am referring to a simple Inet function call.  My issue is a little more complicated than that,  I would suggest, just so you know what I am talking about, to check out www.ninite.com.  you select check boxes for applications you want to pack into a single "exe" file, then submit the form.  The next page (wherein lies my issue), starts the download for the GENERATED exe using the inputs from previous page.  Since the URL is not a constant, rather than InetGet, I was wondering if there was a way to simply automate the download manager built into IE to simply save or download the file as it is run through the IE download manager?

As i can see the urls are build like this:

https://ninite.com/7zip-peazip-winrar/ninite.exe [3 applications]

https://ninite.com/7zip-evernote-googleearth-peazip-winrar/ninite.exe [5 applications]

Did you try to build them (urls) and download with the native autoit functions?

Your issue is not that complicated, as i told you in #2 you can listen to the browser events and take proper action, the download "popup" can also be automated (you can grab the control info in the autoit window info).

Hm.  This is something foreign to me.  As for the popup window being controlled using windows control functions, that won't work because IE 11, since the buttons are not listed as actual controls (see pic) to click.  Furthermore, the whole point of just catching or automating downloads from the built in download manager is the only real solution I will accept for one reason: the fact that the excutable is built using a URL schema means that the owner of the service could, at any point in time, change a single aspect of the URL generation schema, and it would essentially bring operating system deployments to a grinding halt until I go, find what has changed (could be as simple as one program in url list appeared farther down the list), rewrite the script with management breathing down my neck like the vultures they are, and then incorporate it back into deployment process.  This is about scalability and reducing number of points of failure.  Using the actual download manager to catch the download reduces the work I have to do all around (the whole point of automation), which is why building the URLs within the scripts may but it at first, but not for long run.   However, I feel we are getting a bit off topic, as I have said, this is just an example that is similar to the project working on now.  This project is already done and implemented (due to time restraints).  For a better idea as to what I am looking for, look here.  However, "listening for browser events" is not something I have ever tried before.  Could you elaborate more on that?  Would you be able to provide an example of what this would look like?  Maybe incorporate it into aforementioned project for simplicity?:

Do you know any settings in IE which will avoid this POP UP "Do you want to run or save ......."
I just want a situation when files will be automatically saved.

I was thinking about File Download Restrictions:

But I never test it.

The lack of ability to automate the download in IE has been a frustration for me, and for others too I bet. Implementing a custom download manager is beyond my abilities. If you can get it to work, I'll be happy to know.

now for a more practical and efficient solution - how about you create the package once, and deploy it along with your script.

if your script always checks the same apps in the ninite package, then why bother redo it all again and again for every machine, waste time and bandwidth, tackle all the issues you mention.

this is also good for version control. When you get a ninite package for each machine, as you do now, you have no control of which version of which app is deployed on which machine. When you create the package once, you know exactly which version of which app you have. You need only recreate the package when newer versions of apps are available in ninite. No shorter interval than once a month, I dare say. If you also handle updates to ninite-deployed apps, this kind of version control is very useful.

@orbs, what kind of automation in IE download you are looking for (start/stop/resume)? Also, did you try my example in #9? If you really want to click and use the build in download manager in IE, you can easily use UI Automation to "open" / "save" / "saveas" / "cancel" etc, then you can open the download manager (ctrl+j) and get some limited information. Now if you are talking about COM access you can build your own IE Custom Download Manager, i found these example (never tested myself).

The purpose of using Ninite would be so that you get the latest version rather than one you might have downloaded a year ago.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Back up and restore Windows user files _Array.au3 - Modified array functions that include support for 2D arrays.  -  ColorChooser - An add-on for SciTE that pops up a color dialog so you can select and paste a color code into a script.  -  Customizable Splashscreen GUI w/Progress Bar - Create a custom "splash screen" GUI with a progress bar and custom label.  -  _FileGetProperty - Retrieve the properties of a file  -  SciTE Toolbar - A toolbar demo for use with the SciTE editor  -  GUIRegisterMsg demo - Demo script to show how to use the Windows messages to interact with controls and your GUI.  -   Latin Square password generator

what kind of automation in IE download you are looking for (start/stop/resume)? Also, did you try my example in #9?

what i was after is just to instruct IE to perform the download automatically. now i tried your code and i find it quite impressive! i was not aware of the ability to hook into events with a custom function like that, i must study that technique further for future implementation. it certainly beats UI automation in every way.

The purpose of using Ninite would be so that you get the latest version

my original suggestion was to recreate the package whenever a new version of any included app is available - which makes a decent update policy in my view, but mainly it is meant to allow skipping the IE part from performing on each machine altogether.

however, as i mentioned i tested the code in post #9, and found something quite odd. i was under the impression that the ninite.exe is a self-contained installer for all the selected apps; however it seems that ninite.exe is merely a catalog, which when launched, downloads the selected apps from the web for installation. is this indeed so?

when performed per every machine, i find this to be a terrible waste of time and bandwidth, as well as forcing web access as a pre-requirement for image build, which is not always the case. but the worst part is that there is actually no need to recreate the ninite.exe package at all! and makes the process performed per every machine even more pointless and wasteful than already is.
