How can i extract symbol table and Abstract syntax tree of a java compiler
How can i extract the Abstract Syntax tree and the Symbol Table from the class file of java.I need to have the code for extracting it.
Can anyone help me in this matter.
Sreeram
Everything that it is possible to retrieve from a class file can be deduced from the class file definition.

I am a teacher setting up a tracking system using Numbers for the first time. I have set up a summary sheet with puil information, some of which is "looked up" from other tables within the document. It is working brilliantly until we regrouped the pupils.
When i reorganise the students on the summary page I want the same order to follow on all subsequent tables.
However the pupil lists on all subsequent pages stay in the original order!
Hope this makes some kind of sense as I am about to throw macbook out of the window!

Thanks again

Dave,
I might use Match, Offset and Column in my expressions. There are many approaches to this
Match will tell you which row your person's data is in, and OFFSET will then take you to the row indicated by Match and the column indicated by COLUMN().
Let's say you want to access the data for Pupil A. Further assume that the string "Pupil A" is the content of Column A, essentially the title of the record.
MATCH(A, AF1 :: Table 1 :: A) will return the number of the Row in the source table where Pupil A is found.
INDEX(Main, MATCH($A, Main :: $A), COLUMN()) will get the content, in your case the checkbox status.
You are done if you are happy with displaying "TRUE" or "FALSE"
But if you want, you can substitute graphics, like this:
=IF(INDEX(Main, MATCH($A, Main :: $A), COLUMN()), "☑", "☐")

How can I extract pages and maintain links.
I have a catalog index several pages long and all links to various pages in rest of catalog.
I want to extract those pages with the links to the pages intact and insert into a modified version of same catalog. Page numbers remain exactly the same.
When I extract the pages the link appears to be there(hand changes to finger pointer), but the action has been removed. When you click you go nowhere.
How can I extract these pages and re-insert with links intact?Hi lenm,
To extract pages, you need to use Acrobat (not Adobe Reader). As I can attest (because I do have both Reader and Acrobat installed on the same computer), it is quite easy to open files in Reader when you mean to open then in Acrobat. So, please make sure you have the right app open. (I pull this one all the time!)
Now, if the Tools menu is missing from Acrobat, choose View > Show/Hide > Toolbar Items > Show Toolbars to make them reappear.
Please let us know how it goes.
Best,

How can I extract certain pages from my document and save as another file?

You would need Adobe Acrobat to do that, not Adobe Reader.

I am trying to fill in a form in adobe exportpdf. How can I fill in numbers and symbols? Parenthesis, dollar sign etc.
Hi;
Can you provide a little more detail, maybe a screenshot? ExportPDF only converts PDFs to other file types, what exactly are you using to try to fill out the form? The two Adobe form filling tools I would recommend would be:
1) Adobe Reader - a free download you can install on your computer and can be used to fill out most any form. For numbers, symbols etc it can depend on the field you are entering data into, some fields have restrictions, but you would use those keys on your keyboard, if nothing is entered then that field probably has restrictions.
2) Adobe Fill & Sign: https://cloud.acrobat.com/fillsign - using the Fill & Sign tab on the acrobat.com website you can fill out most PDFs. To enter numbers, symbols, etc you would simply add them using your keyboard.
Thanks,

How can I extract a still picture from footage in iMovie, add text to it and print it ?
How can I extract a still picture from footage in imovie, add text to it and print it ?
Assuming you have iMovie 11 (also known as Version 9.0.4), here is how you do it. (If you have a different version, let me know. The instructions will be different).
First, get an app called MPEG Streamclip, which is free. (google MPEG Streamclip from Squared 5)
Open MPEG Streamclip.
In iMovie, select the clip you need. Then, right-click/Reveal in Finder.
Drag this clip into MPEG Streamclip
In MPEG Streamclip, move the playhead to the frame you want.
In MPEG Streamclip, click FILE/EXPORT FRAME.
Choose JPEG, TIFF, or PNG and give it a name.
You can then use this photo in Photoshop, Pixelmator, Acorn, or the app of your choice to add text.
Here is a demo I made the other day for how to extract the still image using MPEG Streamclip. -
How can Import Mysql my database and Table into website -
Hi,
friend i am using CS3 ,i made all need tables in database ,I need to know
how can import that database /table into website.
I know in domin there is admin Mysql inside i have found impotr/export/ but
when I click import i do not know where my database/table been save to import itIf all you are trying to do is change an existing tablepace from a single datafile to multiple datafiles, then a simple import will work fine. Just create the tablespace in the new database with multiple files, then do the import normally.
If you want to move segments into different tablespaces, or change the names of the tablespaces, then you will need to precreate the tables before importing. Then, do the export with indexes=N and constraints=N. Run import with the resulting file, then re-create the constraints and indexes in the new tablespaces.

How can i extract a person from a picture and then animate the person
how can i extract a person from a picture and then animate the person
Basically you select the person using the various selection tools, copy the selection to the clipboard, and paste the selection onto the destination picture. Then use the Move tool to resize/reposition the person as necessary. Here is a tutorial demonstrating this as well as some advanced techniques.
