Gurus,
I am using uipath(A Ui Based Automation Tool) to download a file from a website using chrome browser.
I want browser to not prompt before downloading and just download the file in the downloads folder.
From various posts on this website i found that there exists a file called "preferences" which can be modified to solve this problem.
Before coding further i decided to do the changes in the "preferences" file manually on multiple machines, just to make sure that the changes i do in the preferences file reflect in the chrome browser as well .
I am manually modifying values for these 2 options in the preferences file.
download.default_directory
download.prompt_for_download
When i changed value for download.default_directory(Manually in Preferences file), it reflects the same in the chrome browser settings on every machine that i tested on.
But When i change value for download.prompt_for_download, it reflected in the chrome browser settings on some of the machines while on others i found that it does not reflect in the browser and rather the preferences file also seems to have reverted back to previous values.
The steps i followed are as below..
close any running instance of chrome
do the modifications in the preference file and save it
open chrome and go to settings>advance and downloads
i see DreamCatcher pointing to a similiar situation in this post, but no answers there..
I hope I can help solve your issue or at least give you some direction :)
Option#1: Chrome Settings
Wouldn't the problem be solved by changing the settings for downloads in the browser before running the bot? https://support.google.com/chrome/answer/95759?co=GENIE.Platform%3DDesktop&hl=en
Option#2: Do it in UiPath
And the other thing, is that when the prompt (to save the file) appears, couldn't you insert the path of the file that includes the default folder to save + name file + extension? (e.g. on the save path of the prompt, use type text "c:\myDocuments\downloads\filename.ext" ? I've done this in the past with UiPath...get the prompt window, type text and just modify the string being passed to carry the path, file name and extensio...then click "SAVE" or use hotkey "Enter"(if the file requires replacement, these are another 20cents you will have to program in UiPath, but it'd doable).
Option#3: Script
Another option, which I have not done, but see my friends do is creating BAT files to reset certain browser settings or the "registry"...so what they do is that they configure the BAT to do the changes to the browser and they add an activity (in UiPath) to invoke the BAT file every time the browser is opened by the robot.

I'm having an issue with a local .HTML file.
Everytime I try opening it on ANY browser and on ANY computer it does not work, it opens normally for a brief second and then I get the screen saying the file path could not be found. If I spam refresh fast enough I can read the first lines.
The .HTML file has been extracted from a .war file.
If I copy the code into a new file and open that one, it opens up nicely.
The weird that got my attention was the path for the files themselves on the browser
The one directly extracted from the .war file is as follows:
file:///C:/Users/username/Desktop/New%20folder/help/User_Guide.html?1userhelp.html
but there is no file "User_guide.html" on the folder
If I create the same file just under the desktop directory it opens up without problems, so the issue is not the content of the file itself.
Does anyone have an Idea to what may be causing this problem?
As suggested by SunnyPatel
We aren't sure which OS you are using, and so case-sensitivity may play a part in this. If you're on Windows, you can try viewing the parent folder in the browser, and see if you can click on the file within the default index page and open it from there
Opening the file by first going into "/index.html" worked just fine. The whole navigation flows perfectly, the issue was just me trying to open the file directly.
I have found a lot of answers on how to do the exact opposite of what I'm looking to do, but nothing really on what I'm trying to do.
I have an EXE file that I want to use to open an HTML file in the user's browser as soon as it is executed.
I have two files in the EXE - autorun.inf and index.html. The index.html is what I want to open.
In autorun.inf I have:
[autorun]
open=index.html
All this does is open an error box that says "Installation Failed".
You don't say what language you are writing the .exe in. The easiest thing to do would be to have that program launch the html file. For example, in VB/C# you would add the following inside your main method:
System.Diagnostics.Process.Start("pathtohtmlfile.html");
No need to do anything in the autorun.inf file.
i am currently encountering an issue where I'd like to put a link to a shared excel sheet in our intranet.
Unfortunately the normal href="http:..." link automatically opens and saves it to the local machine instead of enabling the work on the shared sheet which is on the server itself.
I have read through here a bit and found solutions like : file://///SERVER/PATH/Excel.xls
but sadly that solution doesn't do anything.
If its relevant: my server version is Windows Server 2012
You can tell browser to open with Excel (if installed) by adding ms-excel:ofe|u| in front of your Excel file Url.

HTTP is a stateless protocol. What that means for you is that when your users download a file from the intranet via http, they are downloading a copy, rather than the original. Any changes they make will only appear in their copy, and then you end up with loads of copies of the same workbook with different, possibly overlapping changes. You don't want that!
And also ... how are your users even going to upload their changes?
You need to create a shared folder on your network and put the workbook there. You can then use the file:///SERVER/PATH/FILE.xls format in your <a /> links on your intranet to direct your user to the actual file on the server.
I would recommend you start by creating a simple html doc on your desktop to get familiar with the file:/// path format.
Eg
<html>
<head />
<body>
Click
<body>
<html>
save that in notepad and rename the extension from .txt to .html.
You can also type file:/// paths straight into windows explorer's address bar which allow for testing paths without resorting to the html document mentioned above.
UNFORTUNATELY! It seems that the browsers default behavior is to always download a link rather than open it (even if it is a local resource), so if you actually want to open it then you must resort to changing your browser intranet permissions to allow JS to access local resources, which then allows you to use the technique below.
This article (http://www.codeproject.com/Articles/113678/How-to-execute-a-Local-File-using-HTML-Application) uses
<script type="text/javascript" language="javascript">
function RunFile() {
WshShell = new ActiveXObject("WScript.Shell");
WshShell.Run("c:/windows/system32/notepad.exe", 1, false);
}
</script>
to open notepad. You can use command line arguments with Excel.exe (https://support.office.com/en-za/article/Command-line-switches-for-Excel-321cf55a-ace4-40b3-9082-53bd4bc10725) to tell it what the file path is...
Excel.exe "C:\PATH\Excel.xls"
Use the below link if you are trying to open local file in excel.
Open in Excel
Note: The file path should have forward slash
In the google chrome version 30.0.1599.101 m I am not able to save the changed js file.
On saving the js file I got yellow triangle symbol with "change to this file were not saved to file system" message.
I know this used to work in older version
I am using windows-7 64 bit
Click on the cog in the developer tools window (lower right corner)
Go to workspace and add the directory which you would be working on.
This is to accidentally prevent you from modifying files that you did not intend on changing.
Happened to me too. After picking the workspace directory, I also mapped the file from the "Source" panel of Devtools to its filesystem equivalent (using right-click on the file, from the file tree). It solved my problem.
In chrome > 63, accepted answer option is disabled.
In later should be done through workspaces.
Tonight, I accidentally managed to fix this problem, just open the file on the disk and save it with a simple change even with a space.
Refresh the page in Chrome, Chrome will link it(The file) to the disk.
Using Ctrl + F5 to clear the browser cache worked for me.
I found nothing in "workspace" that seemed relevant, and other things people listed didn't help either. What helped was to go in dev tools, where it says Pages, Sources etc., there is also Overrides (duh :)), I chose it, it said "Select folder for overrides", I did, and then also clicked "Allow" on Chrome asking for confirmation. That's it, after that I was able to save the files, the overrides worked.
Ok, my case might be a bit different but I will share my experience on what I was facing that caused to this warning and how I solved it.
I was trying to check a certain strange behavior on a React app for video streaming, so I opened up Developer console, enabled local overrides and tried editing the js file, immediately upon saving I got the warning “Changes to this file were not saved to file system”.
Note the message at bottom right “Source mapped from app.bundle.min.js”, this indicated that this is not an actual file but a mapping from the app.bundle.js (Webpack bundle)
So I moved to editing the app.bundle.min.js, I searched the appropriate string I was interested in from the mapped file (react-dom.production.min.js) and searched it in app.bundle.min.js
Again I got the same warning but I noticed the “app.bundle.min.js” file was fetched using a url parameter ?v=4900, I decided to remove it to check if that was the culprit causing the issue, to achieve that I modified the index.html file and edited the script tag that was fetching the js file from
<script src="libs/app.bundle.min.js?v=4900"></script> to <script src="libs/app.bundle.min.js"></script>
After that I forced refresh the page (Shift+F5, normal refresh didn’t work), tried modifying and saving and Jackpooot!! (Take away: You can’t override files fetched with a url parameter). I then was able to beautify, modify and override the app.bundle.min.js implementation and achieved what I wanted.
On Chrome Version 109~ :
Go to F12 > Sources Tab > Overrides (You may need to click the chevron next to Page)
Select/Create a folder to contain Overrides
You can now right-click a file or editor window & save it for Overrides
Image of sources tab where Overrides is located
Something to note: if you are making dynamically loaded JS available in devtools via the helpful: //# sourceURL=Example.js comment, this network to local mapping will not work.
Note: Notice the "//# sourceURL=dynamicScript.js" line at the end of dynamicScript.js file. This technique gives a name to a script created with eval, and will be discussed in more detail in the Source Maps section. Breakpoints can be set in dynamic JavaScript only if it has a user supplied name.
https://developer.chrome.com/devtools/docs/javascript-debugging
When you're using sourceURL, you can't actually find the respective JS file in the Sources tree where you might expect it to exist. It is available to open via the "no-domain" tree, however (or quick open with CTRL/CMD+P).
I'm still looking for a solution.
The easiest solution I found to this problem:
(keep in mind, I was manipulating an html page that lives on my machine)
open the associated html page from the command line so the page displays
for mac, that's simply $ open <name>.html
open Dev Tools
open Sources tab
in Page, open a new .js file there with whatever name you need
write in some text and save
This worked for me. Yes, I had to create a new .js file, but my directory locally recognized it was there when I pulled it, and my editor was updating in real time with the dev tools each time I saved either. At that point, my editor and the dev tools source tab had become one thing.
Currently on Chrome 100.0.4896.60 (Official Build) (x86_64).
I've got a js file with source maps; the override has always been spotted.
I'm able to override the map file (which won't work though for the debugging purpose) and the index.html file.
Apparently my issue is related to minified js with source maps.
Seem to work in relation to the chrome version installed.
I tried the following attempts but didn't work:
remove cache
disable / enable override
add the dir to the workspace
install chrome canary
To debug then I've tried:
build my file.min.js to test. In my case was production/file.min.js
start a npx http-server in production (cd production && npx http-server) which open to http://127.0.0.1
override index.html to consume http://127.0.0.1/file.min.js
Interesting considerations:
When i was doing basic overriding i had to replace the file manually all the times.
Now, I've got a watch task going on and i can basically refresh the page.
I can see as well the source map update.
It's simple! Right click on your page, Go to Inspect, go to the Network tab and tick the check box 'Disable cache'. Reload the page and you will see the effect.
