After some update to either Visual Studio (I have the same issue in both VS2019 and VS2022) or Chrome I can no longer update the CSS in DevTools and have it reflect and persist the changes to site.css file in my project. Instead when I try to change a CSS property I get the following in the DevTools console:
Unable to find a stylesheet to update. Updating all local css files.
15:54:01.800 aspnetcore-browser-refresh.js:82
And the green dot disappears from my CSS pane immediately after I hit the up or down arrow on my keyboard to try and change the CSS value.
Why is that? It used to work not too long ago. I think it's been broken for me for half a year or so now.
I've been googling but haven't find any good resources. Or maybe I'm the only one coding directly in Chrome? :) Surely this can't be the case?
If anyone knows a workaround please share because I'm really frustrated atm :)
Disabling "Enable CSS Auto-Sync" seems to do the trick.
Update 1: The above no longer works for me for some reason. I managed to find another fix on SO: https://stackoverflow.com/a/70096917/687549
And here are some screenshots:
Update 2: Update 1 works when you only need to update the CSS directly in Chrome. It's better to have Hot Reload enabled and the set the following setting to None - then you'll get the best of both worlds (Hot Reload + Edit CSS directly in Chrome using workspaces): https://stackoverflow.com/a/68954979/687549
Update 3: I'm now using VSCode. If none of the above works try the following (block .js file in Network tab in Chrome DevTools): https://stackoverflow.com/a/68966524/687549
A coworker and I were having a discussion about what is and isn't possible within the browser.
Then a question came up that neither of us could answer with certainty.
Can you create a webpage such that when you navigate to it, it engages the client-side printer and attempts to print a document. For instance, whenever you visit my personal website, you'll be treated to a print out of a picture of me, smiling.
Now, this is a hideous idea. I'm aware. But the discussion intrigued me as to if it could be done, and how. My friend insisted that the best you could do was pop up the print dialog for the user, they would have to click print themselves.
Would it be possible to bypass this step? Or just some fancy script to move the mouse over the print button and click on it? Or use an activeX control to interface with a Printer API directly?
You have to prompt the user to print the current page, there's no way to bypass this step (possibly in activeX for IE). That said, there's two different ways you could prompt the user to print images of you smiling when the page is loaded.
Here's how to do it in JavaScript.
window.onload = function() {
var img = window.open("me-smiling.png");
img.print();
}
And here's how to do it in css/javascript/html (assuming your picture has the id 'me-smiling'):
CSS:
#media print {
* {
display:none;
}
img#me-smiling {
display:block;
}
}
Javascript:
window.onload = function() { window.print() }
The only solution to avoid print dialog that I found was creating a variable on Mozilla Firefox to set auto-print. Maybe is not the best solution if you need to use other browser, but in my case, I only need to print a report automatically and it works:
1- Open Firefox and type "about:config" in the address bar
2- Right click on any preference and select "New" > "Boolean"
3- Add a variable called "print.always_print_silent" with "true" value
4- Restart Firefox.
Hope help you!
AttendStar created a free add-on that suppresses the dialog box and removes all headers and footers for most versions of Firefox.
https://addons.mozilla.org/en-US/firefox/addon/attendprint/
With that feature on you can use $('img').jqprint(); and jqprint for jquery will only print that image automatically called from your web application.
As far as I know, there is no way to print a document directly, without some client intervention, like setting browser flags.
In our current project we need to print directly to the default printer, but at least with Chrome you can do it easily with additional startup arguments.
To print directly to the OS default printer you can use:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --user-data-dir=c:\tmp --kiosk-printing http://www.contoso.com
Another option, which may also be useful, is tos use the native print dialog instead of chromes print preview.
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --user-data-dir=c:\tmp --disable-print-preview http://www.contoso.com
Note, that window.print() and/or Ctrl-P behave accordingly the mentioned settings.
I know, that this does not exactly answers the OPs question, but I think it somewhat related, and for web based enterprise applications this is a quite common use case. Maybe someone find it useful.
For Firefox I recommend Seamless Print Addon
You can't bypass the print dialog, as far as I know. That would be a pretty obvious security flaw if the browser allowed that. But you can bring up the print dialog with "window.print()".
I think at best you would need an ActiveX component using base windows API to obtain a device context for the default printer and try and print an embedded image using assumed values for the printer settings.
To print to the default printer automatically without seeing a print dialog prompt, I've shared some code in the following question that works in IE7, IE8 and IE9:

From lot of search from last few days,
I've found a best possible solution.
Till date Chrome do not support direct printing from javascript.
It has launched USB and serial API which might help.
But currently I'm using a JavaApplet solution which is open source.
https://github.com/qzind/qz-print - build
While I'm getting error in building it. I preferred a Prebuilt - QZ Print Plugin 1.9.3
desktop app, which works great.
Download it from here: https://qz.io/download/
Code Example:
/***************************************************************************
* Prototype function for printing an HTML screenshot of the existing page
* Usage: (identical to appendImage(), but uses html2canvas for png rendering)
* qz.setPaperSize("8.5in", "11.0in"); // US Letter
* qz.setAutoSize(true);
* qz.appendImage($("canvas")[0].toDataURL('image/png'));
***************************************************************************/
function printHTML5Page() {
$("#qz-status").html2canvas({
canvas: hidden_screenshot,
onrendered: function() {
if (notReady()) { return; }
// Optional, set up custom page size. These only work for PostScript printing.
// setPaperSize() must be called before setAutoSize(), setOrientation(), etc.
qz.setPaperSize("8.5in", "11.0in"); // US Letter
qz.setAutoSize(true);
qz.appendImage($("canvas")[0].toDataURL('image/png'));
//qz.setCopies(3);
qz.setCopies(parseInt(document.getElementById("copies").value));
// Automatically gets called when "qz.appendFile()" is finished.
window['qzDoneAppending'] = function() {
// Tell the applet to print.
qz.printPS();
// Remove reference to this function
window['qzDoneAppending'] = null;
};
}
});
}

This is the best solution that I have found for firefox:
There is this awesome add-on Seamless Print.
It works like charm.
Im developing a site and I would like the page to refresh when a change is detected to a CSS file. I used to be able to do this easily with the following bookmarks, but now none of them work on Chrome.

I cant change the HTML of the site im working on so I cant use the livereload app. Ideally I would keep using Chrome but I would switch to another browser if necessary.
You have two ways:
Edit css file and use livereload to reload it automatically in Chrome
Change your CSS in Chrome and save it (without IDE using).
About livereload(it works not for css only).
Use livereload. You need download Livereload 2 and add javascript file to your page or use Chrome extension.
This script is meant to be included into the web pages you want to monitor, like this:
<script src="http://localhost:35729/livereload.js"></script>
LiveReload 2 server listens on port 35729 and serves livereload.js over HTTP (besides speaking the web socket protocol on the same port).
A slightly smarter way is to use the host name of the current page, assuming that it is being served from the same computer. This approach enables LiveReload when viewing the web page from other devices on the network:
<script>document.write('<script src="http://'
+ location.host.split(':')[0]
+ ':35729/livereload.js"></'
+ 'script>')</script>
However, location.host is empty for file: URLs, so we need to account for that:
<script>document.write('<script src="http://'
+ (location.host || 'localhost').split(':')[0]
+ ':35729/livereload.js"></'
+ 'script>')</script>
LiveReload.js finds a script tag that includes .../livereload.js and uses it to determine the hostname/port to connect to. It also understands some options from the query string: host, port, snipver, mindelay and maxdelay.

About changing CSS in Chrome devtools.
Just take a minuit and watch a demo from Paul Irish
Maybe it can fit your needs, since I don't know what editor you use there is two nice ones with embed live editing, are: Brackets IO (free) and JetBrains WebStorm. If you dont ever want to change editors, like Pinal said, Livereload it's a good one, but sometimes its litte bug to make it, but it's a good choice!
You can use Code Kit https://incident57.com/codekit/ and get the free trial and use it for 10 days or you can buy it for $29, I think its totally worth it. You can use Fire.app also http://fireapp.kkbox.com/. Tincr is also a nice app you can use and I think this one is free http://tin.cr/. Hope this helps!
Do you see any errors in chrome console? all 3 bookmarklets work fine for me on chrome 35.0.1916.153.
The change might come from your sites server, e.g some servers block requests with additional parameters. In that case you'll need to modify bookmarklet to not add it.
I often need to display MyFile.aspx in the browser while it's not the actual file I'm working on: I might be working on a .js file that's referenced in Myfile.aspx file, or some back-end library.
So I have to switch from the tab I'm on the MyFile.aspx tab and then click the View In Browser button. Is there a way to avoid this extra step? I know I could set MyPage.aspx as the default start page and hit the Play button but then the whole site would be rebuilt and it would take even longer than finding and switching tabs constantly.
How can I add a button to the toolbar that directly previews MyFile.aspx in the browser?
I'm using VS2012 RC (really cool BTW)
Thanks for your suggestions.
Yes. You just should:
Go to Tools->Customize
Select the tab "Commands", click on the "Keyboard" button.
In the "Show command containing" textbox, type the following: file.viewinbrowser
Set a hot key for this
well your easy answer is to just keep that page open in the browser and just refresh the browser
a more complicated answer would be to add a external tool' command to do this. Go to Tools -> External Tools... and a new entry with the Command being C:\Program Files (x86)\Internet Explorer\iexplore.exe or whatever your browser of choice it and then put your URL in the Arguments field. If you want to assign this to a keyboard shortcut, follow the instrucutions at http://msdn.microsoft.com/en-us/library/80cb6ks3.aspx
I don't known what happened but fdb.exe now always start debug swf in IE
And IE not my default browser!
How to return its default behaiviuor? (embeded browser only with swf)
Are you using Flex Builder or Flash Builder?
If so, go to Window > Properties > General > Web Browser and click new. You will then need to add the path to your browser and its name.
Select the browser you added and it should work.
For some reason eclipse doesn't like to launch the actual default browser sometimes and you have to manually specify it.
