Extract html content on load of a web page

Hi Guys,
I have a small question regarding IE add-on. i want to build a add-on which will extract html content whenever a web page loads in my browser and it should send the content to my application(Server) by ajex/http request afterwards. Can you please tell
me how should I proceed?
Thank
You..

What web browser are you using? Does it develop by yourself? Are you using C# , VB or C++?

Unable to send web content emails from mail as web page since upgrading to the new OS X 10.9

I am no longer able to send web content emails from mail as web page. The images / layout no longer transmit. This started when I upgraded to the new OS X 10.9. The emails appear correctly in the orginal message prior to sending but once they are sent all the images and layout are removed. The sent message folder shows the emails in the changed versions vs what the draft showed prior to sending. If the webpage is only an image my final sent message will only show an empty box with an question mark.

Hold down the option key and select
 ▹ System Information...
from the menu bar. In the window that opens, select
Hardware ▹ USB
from the list on the left. On the right you should now see a list of all connected USB devices, as well as some built-in components. Is the device shown?

After updating my iPod 4 and my iPhone 3gs to 5.1 it keeps turning itself off whenever I'm trying to load a larger web-page, or doing some hard operations. Is there anything I can do to fix this?

After updating my iPod 4 and my iPhone 3gs to 5.1 it keeps turning itself off whenever I'm trying to load a larger web-page, or doing some hard operations. Is there anything I can do to fix this?

Have yu tried the standard fixes:
- Reset. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears
- Restore from backup
- Restore to factory defaults/new iPod.

Firefox won't load parts of web pages or let me log into certain websites

I don't quite know how to really explain this, so I'll provide two examples of the problems I'm experiencing:
The first is that, whenever I go onto any of those Wikia sites, Firefox doesn't seem to load anything other than the main page content. By this, I mean that it won't load any "Recently edited/added pages" box or "Recently uploaded images" box on the right hand side of the page, nor will it open the Contents tab to navigate different sections of the main page content itself.
Another problem I'm having is logging in to a website I usually frequent. It uses Facebook, Twitter and/or Google+ to log in, and the site has recently started running on Flash and Silverlight. Up until a few weeks ago, I am unable to log in to this website for the same reason as the example above - it just doesn't seem to load after clicking to log in, yet the rest of the site is fully functional.
In regards to the former example, I did manage to do something with Java that managed to fix it, however when attempting to emulate the solution when it happened again, nothing happened. I'm unsure of what the problem is. Can someone help?

You can try these steps in case of issues with web pages:
You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
*Hold down the Shift key and left-click the Reload button
*Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
*Press "Command + Shift + R" (Mac)
Clear the cache and remove cookies only from websites that cause problems.
"Clear the Cache":
*Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
You can open the Web Console (Firefox/Tools > Web Developer).
Check on the Network tab if any content is blocked and has a file size 0 (zero).

Where do I place the different parts of the HTML 5 published files on a web page?

I recently published an HTML 5 canvas document from Flash. Once the files are published where do they go on a web page? For example, lets say I had 3 animations published from Flash as HTML canvas objects. The files go on different parts of page, let's say in 3 different places in the body. Flash outputs the HTML file, JavaScript file, and whatever images in an 'images' folder. I'm not sure where I would place all these files on my web site. I know the JavaScript goes in the head of the index page. However, where do the other parts go? Further, if I have multiple HTML canvas objects how do I separate the code.
All of the tutorials demonstrate how to publish the file, but give no assistance on how to place the file or files on a web page.
Below is example code from a sample files:
<html>
<head>
<meta charset="UTF-8">
<title>HeadSpinning</title>
<script src="http://code.createjs.com/easeljs-0.7.1.min.js"></script>
<script src="http://code.createjs.com/tweenjs-0.5.1.min.js"></script>
<script src="http://code.createjs.com/movieclip-0.7.1.min.js"></script>
<script src="http://code.createjs.com/preloadjs-0.4.1.min.js"></script>
<script src="HeadSpinning.js"></script>
<script>
var canvas, stage, exportRoot;
function init() {
    canvas = document.getElementById("canvas");
    images = images||{};
    var loader = new createjs.LoadQueue(false);
    loader.addEventListener("fileload", handleFileLoad);
    loader.addEventListener("complete", handleComplete);
    loader.loadManifest(lib.properties.manifest);
function handleFileLoad(evt) {
    if (evt.item.type == "image") { images[evt.item.id] = evt.result; }
function handleComplete() {
    exportRoot = new lib.HeadSpinning();
    stage = new createjs.Stage(canvas);
    stage.addChild(exportRoot);
    stage.update();
    createjs.Ticker.setFPS(lib.properties.fps);
    createjs.Ticker.addEventListener("tick", stage);
</script>
</head>
<body onload="init();" style="background-color:#D4D4D4">
    <canvas id="canvas" width="615" height="400" style="background-color:#FFFFFF"></canvas>
</body>
</html>

All of the sections marked with the <script> tags should go in the head of the About page. From this line: <body onload="init();" style="background-color:#D4D4D4">, you want to take the onload="init();" part and add it to the <body> tag of the About page. You can also add the background color if you want.
The part marked with the <canvas> tag is the part that need to be added to the body of the About page. I don't know what your About page contains, so I can't tell you where it should be placed.

But i dont know how to use it in my problem. If any one know how to do it. reply this.If you have a big, long string with HTML content in it you might try splitting on a regex like so:
String html = ...
String[] imgTags = html.split("<img.*?>");[http://java.sun.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)|http://java.sun.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)]
to get your image tag data and then parsing that to get the src attribute. You can either treat this problem as a big string-parsing problem, or getting some HTML DOM library and using that to structure the page as a tree for easier access.
If you want more help you'll have to show the code you have so far. We can't write this for you.

Safari browser is not loading images in web pages..

It happens so often nowadays.. When I login to my Facebook, it wouldn't load any images, where it will all be blank..Also, few web pages are not loading in Safari, whereas it loads well in other browsers.. I am using Macbook Pro.. Mac OS X Lion 10.7.4.. Safari Veersion 5.1.7.. Has anyone faced this issue ??

Simple text edit html files will not display as web pages using Safari

How does one get Text Edit files saved as HTML to display as a web page rather than showing the code as written? It appears that somehow some sort of code generator is being invoked and causing this to happen. I am not trying to do anything complex, just simple files like "Hello World".

Hi ..
Make sure you are following the instructions as noted here > Creating a Basic Web Page
You may need to turn off all Safari extensions.
From your Safari menu bar click Safari > Preferences then select the Extensions tab.
Switch to OFF.
Then see if it reads as HTML or Hello World.

FireFox Add-ons tab wont load and addons web page is blocked

I just installed FireFox onto a brand new hard drive, when I open firefox and click add-ons the addon tab will not load it just tells me when its connected to the internet the tab will appear but it is connected, also when I go to the addon web page it is blocked a picture comes up of a yellow background with a black 'stick' man with two options get me out of here or add exception i added an exception but then the page just loads wrong.

You probably have Malware installed on your system. See this article:
* [[Is my Firefox problem a result of malware]]
After making sure that you are not infected anymore, you can install add-ons and themes as you like. This is the add-ons web link -> https://addons.mozilla.org/en-US/firefox/
Check and tell if its working.

HTML code is showing up on web page! HELP!

I'm trying to write an index.html on TextEdit but every time I try to open it the HTML code doesn't render and the code just shows on the page. I saved it as a web page with the extension as HTML so I don't believe that the extension is the problem. Help?

How are you trying to open it? It must be opened in your browser. It must be located in your web server's user directory, and the web server must be running.
So in your browser you would put an address something like http://localhost/~yourusername/ or http://localhost/~yourusername/index.html

'Applet loading' message in web page

Is there a way to have a message like "Loading applet..." displayed on a web page until an applet is loaded and running? I have a large applet that takes a minute or so to load at 28.8 and would like to display that message until the applet is loaded, so the user mistakes the browser as being hung.
Thanks,
Ian

IE and I believe Netscape already display a message like that.

Safari won't load MSN Entertainment web pages

I am having some trouble with Safari. Over the same network, the Safari is slower than my older PCs to load web pages, and some pages, usually in MSN Entertainment (particularly movies) won't load at all. I get a Bad Request message on an otherwise blank white web page. Frustrating, especially as this causes my otherwise wonderful wife to complain regularly about the otherwise fantastic iMac I am typing on. Any suggestions? Thanks.

Hello Tom,
Welcome to Apple discussions
Like Klaus, his link works for me as do the two you just posted.
That is on my powerbook 10.4.8 Safari 2.0.4
Do you have DNS Server#s entered in the DNS server field, in Network's,
Show: Airport or Ethernet [whichever is the case] TCP/IP tab , if not try doing that.
You can get the #'s from your ISP or from the PortForward pages.
Also these.....
Verizon (Level3) - these are not restricted to Verizon customers
4.2.2.1
4.2.2.2
4.2.2.3
4.2.2.4
4.2.2.5
4.2.2.6
work well for many users.
If you use Earthlink, the Opt out numbers are not found on the portforward pages, the supported elink DNS are found there, but for many of us they led to highjacking..
The opt out # are as follows...
207.69.188.171 (west coast)
207.69.188.172 ( east coast)
If you're west of the Mississippi, use the west coast DNS server as your primary and the east coast as secondary. And vice-versa for those of you in the eastern U.S.
They come from this the Dead Domain ... blog.
• Make sure your Router is updated with the latest firmware, & that the routers firewall is not blocking MSN, for some reason or other.

Good Luck & please keep us posted.

Pictures not loaded in a Web Page Composer site without admin role

Hello!
I have got an new problem concerning SAP Web Page Composer.
I have created an new site with some paragraphs and some pictures. The problem is when I, with admin role, access this site I am able to see everything. When another user, without admin role, is trying to access this site he is able to see everything but the pictures. All paragraphs or linklists are displayed but the pictures are not available. When giving the user the admin role he also become able to see the pictures.
I know it is a permisson problem but not know where I forgot to set the permissions to "every user". But I do not understand why this is only concerning the pictures and every other Web Page Composer element is displayed properly, although the pictures permissions set to the same as the other elements. When trying to access the pictures by the user without admin role NetWeaver is throwing following exception:
"com.sapportals.portal.pcd.gl.PermissionControlException: Access denied (Object(s): portal_content/every_user/general/eu_role/com.sap.km.home_ws/com.sap.km.hidden/com.sap.km.urlaccess/com.sap.km.docs)"
