This is about IE11, which I know has been deprecated. But I'm on Win7 and it's still a tool I use.
Here's the issue:
I have a task that's boring and can be automated on certain external web pages.
I have created a button within the IE11 Toolbar using the approach described on this page. Unfortunately, that page doesn't provide any guidance about what language or file extension should be used for the actual script.
The button does in fact appear in the toolbar and it finds the file to be executed, and the IE 11 console says that it has "navigated there" when I push the button. But the script does not actually execute.
I have tried the file extensions and languages for .bat, .vbs, .js, .wsf, and .htm...just trying to put up a "hello world" message...and nothing works from the browser button even though the scripts execute properly from the command line or URL.
I have relaxed IE 11's security settings so that it shouldn't be blocking anything. The only IE console messages are informational codes HTML1300 and DOM7011
So...what scripting language/file format will actually work in this use case???
Well, after only a few hours I figured out the only thing that seems to work: the "script" has to be an HTML file and the only language you can use is Javascript. No, you can't execute a .js file from the button...it has to be .htm...
All, I am working on an ASP.NET 4.6.1 web forms application that renders pdf documents natively on a browser.I get an error message only on IE 11 when some pdf documents are rendered as shown in the screenshot saying "The file is damaged and could not be repaired.Local\EWH-6624-0".The same document renders fine on Chrome and FireFox.Has anyone encountered the same issue? I downloaded the same pdf file in Chrome and tried to open this in Adobe Reader version 11.0.22, it gives me the "There was an error opening this document."The file is damaged and could not be opened".Please see the screen shots below
The asp.net application gets the data from a service and renders it on the UI.This is the C# code that does this
var data = getdataAndOtherThingsFromService();
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", data.DocumentStream.Length.ToString());
Response.BinaryWrite(data.DocumentStream);
IE isn't rendering the PDF. As the dialog clearly indicates, the Adobe Reader plugin is attempting to render the PDF but is unable to. That's why you get the same dialog when you download the file and open it.
Chrome, Firefox, and Edge, and even PDF files hosted on Dropbox have their own PDF rendering engines built-in and, apparently, are more forgiving of badly formatted PDF than Adobe Reader is.
Unfortunately, you will never be able to create a consistent experience if you rely on the browser, or browser plugins to render your PDF files. Instead, you'll need to implement something like PDF.js which, while not a perfect PDF rendering tool, will at least behave predictably across browsers and operating systems.
Adding the code below that fixed my issue.This might be helpful to someone in the future
var data = getdataAndOtherThingsFromService();
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", data.DocumentStream.Length.ToString());
Response.BinaryWrite(data.DocumentStream);
Response.End();
I'm trying to use telerik asyncUpload, it works fine in all browsers but in IE9, I should turn on compatibility mode in order to see my file upload process after I select the file, but in this demo site (http://demos.telerik.com/aspnet-ajax/upload/examples/async/webmail/defaultcs.aspx) it works fine in IE9 without need to turn on compatibility mode, how can I do something like this demo site for IE9?
when I select a file in browsers other than IE9, file name is displayed and a small progress bar showing file upload is also displayed, also a small remove button appears beside file name, but in IE9 I see nothing after select my file, I should turn on compatibility mode, I hope this description is helpful, but in demo site, everything works fine for all browsers, what am I missing?
also I'm going to store my images in database, do I need to perform postback? where I my files stored?
I found this article that sounds similar to the problem your having.
http://www.telerik.com/community/forums/aspnet-ajax/async-upload/select-button-with-not-show-the-select-files-window.aspx
Basically there has been a certain problem with the Flash module in IE9, which is related to the Flash. Which could be why your not seeing anything in IE9.
If this is the issue they suggest disabling the flash module with the following JS:
<script type="text/javascript">
Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; }
</script>
I am trying to allow the user to download an excel file, by using
Response.Redirect(
"http://localhost/myapp/download_folder/example excel file_july.xls")
in page load of an ASP.net page
but on the client side i a m getting the following screen in firefox 3.5
You can observe that the file name and file type are shown as empty fields. The ok and cancel buttons are not doing anything.
This happens only in firefox 3.5, it is working in firefox later versions and other browsers.
I tried clearing the Response with Response.Clear(), using Response.BinaryWrite with the file byte array and even tried to open the file with the javascript by calling window.open(url).
you are doing it the wrong way.
just as an example, look at what is done in the question body here:
How to download file and reload
in your case you should probably use an overload of Response.Write.
the point is that you should set some Response headers to tell the browser file name, file length and content type at least.
I'm using uploadify (http://www.uploadify.com/) to upload video to my site then convert them into *.flv using ffmpeg and play preview. But it dosen't fully working with firefox， chrome or safari.
uploadify provides a onComplete interface, so when the script (.ashx, .php) used on your site for saving uploaded files. you can use response.write("blabla") or (echo "blabla") to invoke the javascript function that registed as OnComplete.
i have test with few video files like avi, mpg, mp4, they are less then 50mb,and they all worked with all 4 browsers. However, when i was trying to upload a 75mb mp4 file, it worked in IE, but didn't working in other three. I can see the .flv file has been create in the upload folder, i can see debug messsage output after response.write("blabla"), but the javascript function was not invoked. i.e. the preview didn't play.
anyone knows why? is there a timeout or something on response.write so after a period of time it wont work? e.g. 75mb file took longer time to convert than other smaller size file i tried.
thansk
Could be a timeout from the server or caching issue. Or an incorrect uploadifiy property as stated here
after a deeper looking in the source code, and googling around. the problem is narrow down on
DataEvent.UPLOAD_COMPLETE_DATA and firefox issues
