IE8 on my system generally prints a page as expected.
But for one particular page on the application i am developing, when i choose Print or Print Preview, IE8 hangs indefinitely (This doesn't happen on Firefox).
What peculiarity of a particular web page could cause such an issue in IE8?
Though I have not been able to figure out why IE8 hangs, I am pretty sure it has something to do with the complexity of the rendered document.
Therefore, as a work-around, I excluded certain parts of the document through css when it is printing:
<style type="text/css" media="print">
#excludeComplexDiv {display:none;visibility:hidden;}
</style>
So now IE8 no longer hangs upon giving the print command!

I have a small MVC app, all this app must do is to take search string parameter via text-box and search the database return the data based on the parameter entered. This app works fine in the two of the browser that I have on my machine, it works in chrome and firefox but goes to complete freeze on IE11, it freezes so much so that it cannot even open developer tools nor respond to any click on the landing page.
I am not even too sure what code should I post because I doubt it has something to do with it and if does go down to code I am not sure which part because like I said it works perfect in chrome and firefox
I tried adding the line <meta http-equiv="X-UA-Compatible" content="IE=edge"> on the layout page but that made no difference whatsoever
Typically inability to open dev tools in a browser indicates that something intensive is running in a background. Try to open dev tools prior to entering URL of your application. Sometimes you can find some request looping forever, or wrong javascript.
Using Delphi XE6, I've written lots of service applications that use TIdHTTPServer. Every now and again, a javascript file will fail to load in Firefox, and when I check the Delphi application's log, there's no mention of it.
Example:
In TIdHTTPServer.OnCommandGet, first thing I do is log the requested page. After the page loads in Firefox, the log shows the page request, 3 CSS requests and 3 JS requests - for this example it is correct. But sometimes, and it's usually after I haven't requested the page for a while, despite closing Firefox, and the Delphi service application, one of the JS requests is missing, and it's not loaded in Firefox, so things don't work.
Not sure if it's relevant, but one of the techniques I use is appending the file's last modified timestamp code as a parameter when requesting the file.
eg. in the HTML, it will say <script type="text/javascript" src="general.js?rnd=20150522155113"></script>
I do this to ensure updates to JS and CSS files are always reloaded and not cached.
I'm not sure how to go about solving this. The issue affects multiple delphi projects. I only use Firefox, so not sure if other browsers are affected. Any help is appreciated.
In my rails project sometimes chrome doesn't stop showing "loading circle icon" even after finished a loading. At least it appears all HTML elements are shown and JS works fine.
It doesn't happen in local development. Neither with Firefox and Safari in server environment.
It happens only with chrome in server environments.
What should I do to determine the cause of the problem?
I copied the navbar default sample from from the samples but without any changes it appears to be doing what I think is mobile format. The only thing I see is the brand tag to the left and the button to the right. My monitor is pretty big so it can handle the menu and it does when I view it online which you can visually see here. I can only assume that since I cut and paste from the demo code I have a setting somewhere else that is wrong but I have no idea where to look. I did make sure to run nuget and get the latest version of the code so I should match what is on the demo. Any ideas?
Update
The issue appears to be with VS2012 and debug mode. Using Visual Studio Development Server seems to be the problem. If I publish locally it works as expected. I thought it might be IE8 but realized it was VS2012 after I published the site.
Is there a way to work around this while using the debugger in VS2012?
Update 2
And somehow it is not working in IE8 again even after being published. Chrome seems to work fine. Must be something picky about IE8 that I need to code around.
Try to copy all the page html, then if it works cut unnecessary code.
Use this instead of your local bootstrap:
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<!-- Optional theme -->
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">
<!-- Latest compiled and minified JavaScript -->
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
Looks like this was an issue with IE8 all along. I didn't think it was a browser issue so I never looked for IE8 nav problems but here is a link that documents the issue.
We display a piece of signed XML in a TEXTAREA. The signing takes into account the whitespace, so it is critical that this is maintained.
The user then copies and pastes this into an application that validates the XML... we've not had a problem with this until now... IE9 is rending the text slightly differently.
When I copy it into a HEX editor, I can see that IE9 is rendering newlines as 0xA... put it into compatibility mode (or use IE6,7,8, Chrome, Firefox etc.) and it gets rendered as 0xD,0xA
I guess this won't effect most people, as it looks ok... but for us it is a royal PITA!!!
Anyone come across this, and better have a fix :)
Thanks!!!
Not sure if this is really a fix (and I do wonder if this is a bug in IE9?)
Anyhow, I ended up putting IE9 into IE7 emulation mode for the page in question:
http://msdn.microsoft.com/en-us/library/cc288325(v=vs.85).aspx
<!-- Mimic Internet Explorer 7 -->
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" >
It works, but now, of course I don't have the IE9 features on this page.
