I 'm trying to use Clipboard Copy for one page written in asp.net
I use zClip for browsers except IE , in some browsers(chrome most of the times), my button which do Clipboard Copy doesnt work, when I trace code with F12 in Chrome, this Error apears:
GET http://www.steamdev.com/zclip/js/ZeroClipboard.swf net::ERR_NAME_NOT_RESOLVED
and for one other resource, this Error occurred
Failed to load resource: the server responded with a status of 404 (Not Found)
why some browsers cant Load these Files ???
thanks for Any help or suggestion .
:)
It might be occurring due to browser and Flash security restrictions, the clipboard injection can ONLY occur when the user clicks on the invisible Flash movie. A simulated click event from JavaScript will not suffice as this would enable clipboard poisoning.
It has been mentioned as limitation of zclip plugin in its github repo.
Please refer to github link for more details
And for clipboard poisoning please refer to this link
Also below are some points regarding zclip:
“The ZeroClipboard library provides an easy way to copy text to the clipboard using an invisible Adobe Flash movie and a JavaScript interface”
Advantages:
Stylized the button
Easy to use and configure
Work well on Chrome, Firefox
Disadvantages:
No flash, no action
This clipboard injection can ONLY occur when the user clicks on the invisible Flash

This used to work as a valid href attribute but it seems in the past few months it now shows an error in the console (I'm using Chrome):
Not allowed to load local resource: view-source: http://stackoverflow.com
I found some links from 2013 where this was once a bug in Chrome but said it was fixed.
Could someone point me to an authoritative source that can explain why this no longer works? I assume that this is security by the browser and not an angular issue (since view-source is whitelisted and used to work)
Looks like Chrome and Firefox (at least) disabled this within the past year or so
I found this thread, and these release notes explaining why and provides a timeline as to when the change took place.
Related StackOverflow question: File URL "Not allowed to load local resource" in the Internet Browser
Chrome responds with the "Not allowed to load local resource:" as a security protocol. I'm not sure why this used to work, but not now, though there is no real way around this unless web-security is disabled. There may be a different outcome on other browsers, but ultimately you are correct in thinking that it's Chrome's security.
The reason is that Chrome tries to preload URLs in background, to speed up your browsing experience.
If you open the DevTools after loading the page, the content of the items listed on the Resources tab may not be populated. This is also true of network requests on the Network tab. To see the fully populated resources on the Resources tab, first open the DevTools, then refresh the page, or navigate to the desired page with the DevTools open. Now select the html resource and it should be populated.
I am developing a chrome extension, and my point here is to record a browser tab , like Screencastify chrome extension records the browser tab. I referred desktopCapture , a chrome API which works perfectly for "screen" and "window" as DesktopCaptureSourceType, whereas for "tab" as DesktopCaptureSourceType, it throws an error as
desktopCapture.chooseDesktopMedia: Tab capture is not supported yet.
I have configured the required permissions in manifest.json of my extension. Could anyone suggest me a solution?
P.S : I need to record the chrome browser tab only, am not asking for a screen or window recording
This is a known issue: https://crbug.com/488262
However, you can use the chrome.tabCapture api instead. The downside is that you will have to split your interface between capturing tabs and screens/windows, as chrome.tabCapture doesn't provide an equivalent picker.
Why does Google have two separate screen capture apis? Good question.
The stream object generated by the chrome.tabCapture cant be shared outside the plugin code.
You will have to write the code to share the stream to server within the chrome plugin.
I have a problem with HTML5 appCache on Firefox and IE10.
I have build a minimal test case available on: https://docs.google.com/file/d/0B7CVmRJOMgTNZUxkLWRDNmhtVU0/edit?usp=sharing
Accessing the page at "applicationCache/test.html" the browser will look for the correct manifest and will start to download all the content from the files in its list.
The problem occurs when I put in the list a .php file handling COOKIES; for example I have added a .php file which will call the php function "session_start()".
Chrome and Safari can handle correctly such file during the application cache download.
Firefox and IE10 share the behaviour: they halt and signal a generic error.
During a long search I found out this ticket on bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=722683
Is there anyone who can give me a hint to handle correctly the COOKIES during applicationCache download event, without getting an error ?
Am I doing something wrong or against the standard ?
Thank you for your assistance!
I am not sure but can you make use of the localStorage instead of cookies?
I'm having a very strange problem with a site in Google Chrome:
When I click on a link (from a list view to a detail page), the page hangs and I Chrome throws up a dialogue asking me to kill the page. The page is never displayed.
But if I navigate directly to the page, it loads in Chrome without any problems. Both actions (clicking on a link or navigating to the page) work fine in Safari and Firefox.
Disabling "Predict network actions to improve page load performance" in Chrome's settings seems to fix the problem, but this is not a viable solution as I don't have any control of my user's browser settings.
Some more detail about the situation:
The link is just a regular <href>. I'm not doing any javascript
click() handling or anything else. I'm not using any 'prefetch' or 'prerender' <link> elements.
The pages all validate using the W3
html5 validator.
The page I'm navigating to loads a lot of JS, uses Knockout.js for rendering and loads a video file over HTTP.
On the occasions that the page does load (after a very long wait),
Chrome appears to have rendered the entire page in the background and
loaded all external resources. If I navigate directly to the page it
doesn't preload anything though (I'm using knockout to show a 'please
wait' message while the external resources load).
When I log the network requests using Charles, it appears that
Chrome loads the HTML for the page instantly, but the requests for
the external resources seem to take forever.
If I look at the CPU usage in Activity Monitor, 'Google Chrome Renderer' uses 100% CPU when loading from the href, but only 30% when loading directly from the page.
I'm using the latest version of Chrome (22.0.1229.94)
So - my question
Is there a way to programatically disable "Predict network actions to improve page load performance"?
Or is there some other solution to this problem?
Just going through high voted unanswered questions I came across this one, and I once got into a similar situation for entirely different reasons (chrome was preloading a huge file I couldn't afford to load for every user). The fairly simple solution I applied back then was to open the link through Javascript rather than a simple href which worked wonders. Either way, your problem might already be solved, but seeing the number of views I thought I could at least share this small insight.
Is there any way to communicate between my .exe application and Firefox?
Because, I have my own webpage. I'm using FireFox to browse it.
I have an application (in c++) to process a piece of HTML code from my webpage within FireFox. My application can print something directly to printer (raw print).
Since now, I coudn't access firefox's DOM content (page HTML source) from outside firefox; Also, I coudn't print directly to printer (raw print) from firefox.
Now, I'm looking solution for this problem. Here are my possibilities:
1.) My web page I can copy my related text to clipboard.
2.) My web page I can write my related text to Firefox's cookie.
3.) My web page I can write my related text to a file from client's PC.
4.) Any other way to send my related text to my .exe application.
But I don't know how can I do:
How can I copy to clipboard within firefox,
How can I read FireFox's cookie from my .exe application,
How can I create file in client's PC.
Is there any way to communicate between my .exe application (in c++) and Firefox?
You have to write an extension for firefox an use its API. For example see nsIProcess:
"The nsIProcess interface represents an executable process."
Assuming that your page has a true URL outside of FireFox, you could solve your problem by registering a custom protocol handler. E.g. register "X-myprettyprinter". Then, in FireFox, from http://www.example.com/index.html you can redirect to X-myprettyprinter:http%2D%2Dwww.example.com/index.html. FireFox doesn't know how to handle the X-myprettyprinter protocol so it hands off the URL to the OS, which then hands it to your registered application. Bonus: it works for all browsers. Downside: you have to retrieve the URL yourself and render the page again in-process
You could write an addon for firefox that allowed some form of integration with your application.
Here is a tutorial on writing firefox addins.
The best way to do this is to skip the .exe application and just make an ad on for FireFox, Take a look at the FireBug ad-on. It can pull certain codes out of a web page, If you use the API I bet you could do what your .exe program should.
