Writing mathematical formulae in the comments

I am trying to explain to a bunch of young students, the mathematics in a paper written by Dr Steven Jones in the journal of 911 studies - its a free pdf of excellent quality peer reviewed journal. There are many papers but this is an enjoyable example.
http://www.journalof911studies.com/volume/200609/WhyIndeedDidtheWorldTradeCenterBuildingsC ompletelyCollapse.pdf
The hard part is that
I have to add comments that must involve explaining the equation derivation steps.
These are best added using mathematical equations that are properly typeset.
How do I write a code in javascript or any other language eg TeX or LateX to include math fonts in the annotation boxes ?
For example, a site like wikipedia is able to display equations inside mozilla firefox based on some kind of component.
Is there a similar capability in pdf viewer considering that it is really an extension to xdvi or ghostview ?

How do I hide the comment-field in a pages document?

I'm currently writing a document in pages, and added some comments to my own text (the yellow notes). When I was done with the comments, I removed them, but the area to the left of the document where all of the comments were shown, did not dissapear.
So, now I have a gray area that takes about 25% of the document window, that I want to get rid of.

Look in the menu View!

Firefox froze a webpage, and I want to recover the text I wrote in the comment box on the page.

I wrote a long thing in a comment box at the www.rollingstone.com website using Firefox for macbook as the browser. Typing into the comment box was going slowly and a then a window popped up saying "WARNING: Unresponsive script" in bold and then below it it says "A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue." Then below that it says: "Script: http://www.rollingstone.com/assets/js/built/desktop.bundle.js:185" Then there are 3 buttons:"Debug script", "Stop script", or "Continue", none of which respond. I think the text I entered is still there on the page if I could break this window. I am wondering if it is possible to recover the text I wrote in the box?
The Debugger came on at the bottom of the page, but the window of the rollingstone page won't move so I can't bring it up to see most of the debugger. It looks like the script is some "RubiconAdServing."
I downloaded a hxD editor, but I just get stuff on the right about the URL. In the advice I was given on another site, it says that I should be able to recover the text this way. Maybe I am clicking on the wrong thing to open with the Hex editor.
There were no things in the upper left of my macbook window like 'file' for Firefox, but now they are there but not responding. Firefox is totally not responding, but there are a lot of other firefox browser windows minimized that are open and still at the bottom of the screen, but also not responding. How do you get into Firefox and recover the text? While I was writing the text on the Rolling Stone website, the writing within the tab would show that it had to connect to the internet to enter the text. When I went to the site I entered the text, it was not saved on the site. I can see some of the text I wrote on the frozen Firefox screen, but nothing moves. I am sure the text I wrote it still there if I could get through. How do I get into the Firefox webpage? All the other applications are working on my MacBook.

Try the following:
#Open the Mac Activity Monitor
#End the plugin-container process(es)
Now the page should respond again, but you will need to reload the page in order for it to work again, so copy your comment.

Mathematic formulae in a text document

Hi everybody,
I will have to type a document that would include mathematical notations. I will have to explain standard deviations and various probabilities formulae. The special symbol fonts don't really help because, for instance, I wouldn't be able to write "i=1" and "n" respectively under and above the sigma sign.
So I'm looking for a convenient way to type these formulae in a text document.

Properties: how do I read the comments in it?

I'm using a Properties object to read key-value pairs. But I found I also need to read the comments in the properties file. How can I do that? :)

I think that once you start having that level of detail (eg descriptions) associated with properties, then you should go the XML route.
Property files are great, but for quick control of basically one-dimensional properties. You can use "load" on the file, they're easy to edit in just about any text editor, it's great. But once you need multi-dimensional attributes to the properties, you must use something richer.
If you're writing some kind of Properties file editor -- maybe you're forced to use Properties files for backwards compatibility but you're trying to make them easier to edit for non-techies? -- then you'd skip the Properties.load method, and parse them yourself, with FileReader as yawmark suggested. Of course once you're doing this, you'll be reading both the comments and the properties, and furthermore you'll be imposing some kind of convention ("comments always come before properties, not after", "a blank line separates comments") which can easily be violated, to your chagrin.
I say, either skip trying to read comments, or move up to XML or something, if you possibly can.

Access denied error while writing a file to the file system - myfileupload.saveas() throws system.unauthorizedexception

hi,
as part of my requirement , i have to perform read and write operations of few files [ using the file upload control in my custom visual web part] and on submit button click.
but while writing these files - with the help of fileupload control - and when i use myfileupload.saveas(mylocation);
- i am saving these files into my D:\ drive of my server , where i am executing my code -, am getting access denied error.
it throws system.unauthorizedexception.
i have given full control on that folder where i was trying to store my attached files. and also after following asp.net forums,
i have added iusr group added and performed all those steps such that, the file is saved in my D:\ drive.
but unfortunately that didnt happen.
also
a) i am trying the code with runwithelevatedprivileges(delegate() ) code
b) shared the drive within the d :drive where i want o save the files.
c) given the full privieleges for the app pool identity- in my case , its
network service.
the other strange thing is that, the same code works perfectly in other machine, where the same sp, vs 2012 etc were installed .
would like to know, any other changes/ steps i need to make it on this server, where i am getting the error.
help is appreciated!

Hi Friends,
I have gone through scores of examples and i am failing to understand the right thing to be done to copy a file from one directory to another. Here is my class...So let's see... C:\GetMe1 is a directory on your machine, right? And this is what you are doing with that directory:
public static void copyFiles(File src, File dest) throws IOException
// dest is a 'File' object but represents the C:\GetMe1 directory, right?
fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
BTW, this is awful:
catch (IOException e)
IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
}1) You're hiding the original IOException and replacing it with your own? For what good purpose?
2) Even if you had a good reason to do that, this would be simpler and better:
throw new IOException("your custom message goes here", e);
rather than explicitly invokign initCause and setStackTrace. Yuck!

To avoid writing database code in the front end

Hello,
I am working on a database application using 10g database as backend and dotnet as front end. I wish to execute only oracle stored procedure for all the select (to avoid hard parse and use of bind variable), DDL and DML operations; just to avoid writing database code in the front end. Can anyone please give me a little examples of :
1.Select query's output to be return as resultset by stored procedure.
2.DML example by stored procedure.
3.Any DDL example by stored procedure.
using scott.emp, so that i would just call the stored procedure, rather than giving select,DML and/or DDL commands in the front end. Even though i have read in the documentation, but a clear cut examples will help me to get into clear concept as well.
Thanks & Regards
Girish Sharma

Hi...
-->Select example
create or replace procedure get_emp(rc out sys_refcursor)

open rc for select * from emp;
end;
-->DML example
create or replace procedure do_dml_emp(pempid in number,
pempname varchar2,
result out number)
is
begin
insert into emp(empid,empname) values(pempid,pempname) returning empid into result;
exception
when others then

I have created a PDF and password protected it for view. However, when reading the PDF in Adobe Reader app on the iPad the commenting and annotation options are not available. Is there a way to allow commenting and annotation in the app while password protecting the document?

Is there a setting that needs to be set to allow the annotation features? I set password protection to open and then password for editing and set it to Any except page extraction, but it still did not give the annotation option

In Address Book, new text in the comments keeps disappearing.

Just recently, when I add new comments in Address Book, the new text disappears when I leave the comment box. The previous text remains. This keeps happening. I have restarted the computer, thinking it was a glitch, but no.

Anyone know how to fix this? It's still doing it, but only 50% of the time. It's very annoying and taking up my time at work, as I use the comments field to store info about the customers' orders. I have a ton of open space on my hard drive, so that's not it.

How can I erase a full page of comments on a PDF Form I made all at once. (the comments)

I work for a Hvac Company and we make these Material lists in PDF form. I put these lists in a dropbox and they export it to there tablets. When they edit the list and email it back to me its saved on there tablet and they have to delete the one on there tablet and export a new one. They have to do this many times and it gets to tedious and time consuming. Is there a way for them to delete the whole page before it gets automaticly saved or to stop it from auto saving when they close it out. Or to keep an original copy on there tablet that wont be saved over?

If someone wants to send a PDF file via email it has to be saved first.
To delete comments in the desktop version of Adobe Reader, just select them all in the Comments panel and press Delete. That feature isn't available in the mobile apps.

How can I copy all the comments from my picture/s in fotostream to my picture/s in my library?

How can I copy all the comments from my picture/s in fotostream to my picture/s in my library?

Hi, first, you should prevent the iTunes library auto sync with iPhone: Launch iTunes > click Preferences... > click Devices. In the window, check the option 'Prevent iPods, iPhones, and iPads from syncing automatically'. Next, connect your iPhone with your computer via the USB cable. Click the mini menu for iTunes on the very top left and click the option 'Show menu bar'. After then you can see iTunes File, Edit, View, Control, Store and Help menus on the ribbon. Click File > Devices > Transfer purchases from (your iPhone name). You can also access to the File menu by holding down Alt (Option on Mac), Shift and F keys. This is how to get your iPhone purcahsed song transferred to iTunes Library.

How do I re-number comments in the Comments Summary page?

Hi,
When I create a comments summary page, Acrobat 9 organizes comments by page number and numbers them beginning at "1" for each page. Can I change the settings so that I can have the comments organized by page but numbered continuously? In other words, I want to be able to look at the comments on, say, page 7 - but I don't want the first comment on page 7 to be numbered as "1". If it is the 35th comment in the document, I want it to be numbered as "35".
Does anyone know how I can accomplish this? Any help is appreciated. Thanks!

You can delete them and re-add them accordingly or you can use random which would show the random order of images.
Another workaround can be be done using layers, where you can drag the image to the desired position which you want to show in order with slideshow.
I have created a short video for you , please download from here :

I've been reading the comments re FCPX on MacBook Pro and now I'm scared. I'm taking a class now and thinking about buying to do videos for nonprofits. Won't be fancy stuff, but now wonder if it's a good choice. Also, heard Apple will drop support. Help?

I've been reading the comments re FCPX on MacBook Pro and now I'm scared. I'm taking a class in FCPX and thinking about buying to do videos for nonprofits. Won't be fancy stuff, but now wonder if it's a good choice. Also, a classmate who was in CA last weekend said he heard that Apple will drop support of FCPX. Any truth? Advice?. I'm on 10.7.4 with 2.4 GHz Intel Core 2 Duo, 4 GB 1067 MHz. Thanks.

While it is against the TOU of these boards to speculate on future products/updates what Thomas said is right: FCPX is quite a new product and it doesn't make any sense to drop it now.
The only thing that MIGHT get dropped at a certain point is support for older hardware/OS as FCP X progresses.

How can I move my iPhoto Library from one Mac to another without losing the comments on the individual photos in the process?

How can I move my iPhoto Library from one Mac to another without losing the comments on the individual photos in the process? The source Macbook (OS 10.4.11 and iPhoto 6.0.6 (3.2.2.)) is with my husband in Germany, the target MacBook Pro (OS 10.8.5, iPhoto 11) is with me in Japan. Thanks for your help.

I copied the iPhoto Library to a CD and from there to the new MacBook
If you copied the library to the CD via the Finder it would be no different than the methods Terence suggested. If you used the Share ➙ Burn menu option from inside iDVD you'll get a mini library that has to be accessed from the open library and the events/alubums copied into the destination library. Not the same as the other methods.
The Share ➙ Burn method is no longer supported with iPhoto 9 and later.

Is there a way to change the color of the Commenting indicator?

Our company is utilizing the commenting feature more now in Adobe Acrobat X Pro. This is an attempt to reduce printing on paper. In one of our processes, people will use the comments listed in the Comments Panel to keep track of each note. They mark each one as complete once they've reviewed whatever the note entails. The only problem is, as you click each comment from the panel, the comment is indicated on the page. The indicator that surrounds the comment is a light-blue squiggly line. It's a bit hard to see, so I was wondering if that color could be changed. I would prefer to have it as a red squiggly line.
I see how you can change the comment note colors, but not that indicator line that surrounds the comment. Is that some sort of system color that needs to be changed in Windows??
thanks,
Jon W.

No,
you can decrease the brightness level.

Perhaps some combination of the above will help you.
