Using UIAutomationClient to automate the Save As file download in IE11

Here is VBA code which automates the complete 'Save As' file download procedure in IE11, when a download is offered by IE's Download Notification Bar.

To use for your own web site downloads you would automate IE and do whatever is necessary to make the Download Notification Bar appear at the bottom of the IE window and then call IE_Download_File_Using_UIAutomation. It has the following parameters:

Public Function IE_Download_File_Using_UIAutomation(IEhwnd As Long, ByVal saveInFolder As String, ByVal saveAsFileName As String, ByVal replaceExistingFile As Boolean, ByRef downloadResult As String) As Boolean

  • IEhwnd - The handle of the IE window. The Download Notification Bar must be displayed in the active tab. If necessary, call IE_Click_Tab_Like to activate the required tab before calling this function.
  • saveInFolder - The folder path where the downloaded file will be saved. Specify "" to save the file in IE's default download folder.
  • saveAsFileName - The file name which the downloaded file will be given. Specify "" to use the file name provided by the web site.
  • replaceExistingFile - True to replace the file if it already exists; False to overwrite the file.
  • downloadResult - Output string returned to the caller showing whether the file was successfully download or not, including the file name of the downloaded file (including its path if saveInFolder was specified).
Function return value - True: the file was downloaded; False: the file was not downloaded.

NOTE - The only issue I had was that after calling SetValue to put a specific file name in the Save As dialogue and clicking Save (Invoke), the download doesn't recognise the specified file name and still uses the default file name provided by the web site. A simple workaround which has worked in all tests is SendKeys " ", True to insert a space character at start of the file name input element, however I know that SendKeys is unreliable and this might not always work for some people.

Also note that the IE tab offering the download must be the active tab, and the IE_Click_Tab_Like routine should be called to activate it if necessary. The code also includes several debugging functions which can be helpful to understand the UIAutomation hierarchy.

Here is the complete code, including a test procedure for downloading a 2 Kb csv file from morningstar.com

My god that's a lot of code :shocked: - it must have taken you ages :)

It doesn't actually work for me though. It identifies the download bar, clicks save as, opens the save as dialog and then gets stuck in a loop waiting for input (in here: Function UIElements_To_Cells)

I'm intrigued as to your reason for this epic amount of work, as I know you know full well how to download things from the internet "properly" without automating IE

Yes, it's certainly a lot of code! It was simply a development exercise to see if it could be done, because I've never seen UIAutomation used this way before.

Using Microsoft's Inspect.exe tool, I discovered that the Save As option is in a context menu which is a child of the Desktop element, not the Download Toolbar, as you might expect. I also spent some time trying different methods to fix the issue with the input file name not being 'taken' by the download. You can turn off the calls the UIElements_To_Cells by setting the DebugMode Const to False, but I don't know why it's waiting for input.

Although this was a lot of work initially, callng this function would probably be easier and far less work than writing custom code to download using XMLhttp requests.

Fairy nuff, I can see why it would be useful to point people to on forums, guiding them through doing it the proper way is often impossible. I'm not sure it's easier to do the if you know what you're doing though as you're likely needing to change code whether automating IE or direct requests for each site anyway. I often find it easier to use winhttp rather than xmlhttp too due to the additional authentication options and automatic cookie handling.

Nevertheless - great work :)

Thanks :)

You're right about WinHttp. My default method is usually XMLhttp for simple requests, however one disadvantage is that it hides cookies in the response, whereas WinHttp provides them in the Set-Cookie headers.

Another thing, which you probably know about, is that the following is needed when using Fiddler to capture the WinHttp requests and responses:

Code:
Const HTTPREQUEST_PROXYSETTING_PROXY = 2
WinHttp.SetProxy HTTPREQUEST_PROXYSETTING_PROXY, "127.0.0.1:8888"

I don't really use fiddler - I just use Chrome dev tools for that.

That's not quite what I meant with the cookies, winhttp will automatically send received cookies with each request, with xml you need to add them manually. This is especially useful for scraping pages which require logging in, once you have the authenticated session cookie, winhttp just sends it automatically - xml doesn't. I tend to use xml on forums though as it has fewer issues with corporate networks, winhttp sometimes requires fiddling with for some posters on the forum; xml request also allows for more asynchronousity.

Update

I have come across some websites where, when a file download is offered, IE11 displays a dialogue asking "What do you want to do with xxxxx.xxx?", instead of the normal Download Notification Bar at the bottom of the window. Here's an example:



To see this dialogue follow these steps:

  1. In IE, open website https://www.abs.gov.au/Price-Indexes-and-Inflation
  2. Click on link “Consumer Price Index” on that page.
  3. Click on “Download” tab on that page.
  4. Click on any of the green ".xls" links on that page.
(Thread ref. https://www.mrexcel.com/forum/excel-questions/1110318-navigate-getting-data-website-post5344650.html)

See below for my analysis of this issue and why the dialogue is displayed.

Here is the updated VBA UIAutomation code which handles both this dialogue and the Download Notification Bar.

Code:
#If VBA7 Then
Public Function IE_Download_File_Using_UIAutomation(IEhwnd As LongPtr, ByVal saveInFolder As String, ByVal saveAsFileName As String, ByVal replaceExistingFile As Boolean, ByRef downloadResult As String) As Boolean

Analysis

Why does IE11 display the "What do you want to do with xxxxx.xxx?" dialogue when a file download is offered?

It happens because the website doesn't send a "Content-Disposition" header, or there is a misspelling in the header's value string, or incorrect syntax.

A well-behaved website (e.g. http://financials.morningstar.com/balance-sheet/bs.html?t=INTC&region=usa&culture=en-US) sends the following correct response header with the file download:

Content-Disposition: attachment;filename="INTC Balance Sheet.csv"

and the Download Notification Bar is displayed.

However, https://www.abs.gov.au (https://www.ausstats.abs.gov.au for the actual download) doesn't send the Content-Disposition header. (One of the headers it sends is content-type: application/vnd.ms-excel).

The dialogue is also displayed if the header's value is misspelt, for example:

Content-Disposition: attachement;filename="Data.zip"

Here, attachment is misspelt as "attachement".

Using Fiddler to fix or reproduce this issue

By running Fiddler, we can use FiddlerScript to fix or reproduce the issue with the dialogue. To fix the issue for https://www.abs.gov.au, add the following code to the OnPeekAtResponseHeaders function:
Code:
        if (oSession.HostnameIs("www.ausstats.abs.gov.au") && oSession.oResponse.headers.ExistsAndContains("Content-Type","ms-excel")){
            oSession.oResponse.headers.Add("Content-Disposition", "attachment; filename='Stats_Data.xls'");    
        }
and click the Save Script button. Fiddler calls the OnPeekAtResponseHeaders function before the response headers are sent to the client, hence the above code adds the Content-Disposition header with a fixed file name to the response headers and therefore IE will display the normal Download Notification Bar instead of the dialogue when a file download is offered.

To reproduce the issue, add the following code to the OnPeekAtResponseHeaders function:
Code:
        if (oSession.HostnameIs("your.hostname.com") && oSession.oResponse.headers.ExistsAndContains("Content-Disposition","attachment")){
            oSession.oResponse.headers.Remove("Content-Disposition");
            oSession.oResponse.headers.Add("Content-Disposition", "attachement; filename='Data.zip'");    
        }
The above code checks to see if the Content-Disposition response header contains "attachment" and if so changes it to the misspelt "attachement" with a fixed file name. With this code, IE will display the "What do you want to do with xxxxx.xxx?" dialogue instead of the normal Download Notification Bar. I think the dialogue is displayed only for binary files (.zip, .xls, etc.) and not text files (.txt, .csv). With text files, IE displays the file data in the browser.
