[JS, CS3] Please help--need to search text & then insert at find

Hi all,
I have a nifty script that I use to make stacked fractions by inserting an inline textframe.  It has a dialog which allows you to enter the numerator and denominator.
Now I would like to modify this script to automatically search for fractions within text (for example, 5/16) and replace that fraction with my inserted textframe.
The problem is I cannot figure out how to search for the word containing the slash character and then get the insertion point so I can add my textframe as an inline.  Once I find the word with the slash (the fraction), I think I can split the contents of the fraction at the slash to get the numerator & denominator.  Just cannot pop that textframe in there at that point and replace the word.
Have I made this clear enough for anyone who might be able to help?
Regards,
Len Swierski

Hi Len,
You just sent me on a trip down memory lane. I wrote about this very issue very soon after CS hit the street with JavaScript for the first time. On this page:
http://www.pdsassoc.com/index.php?Nav=javassub&Ban=SettingFractions&Info=jstutorials/Setti ngFractions/index.html
you'll find what I think is a relevant discussion. I required the user to select a slash but that's where you'll be after your script has found a slash. Hope this helps. I was perhaps a tad pedantic on that page but it was all very new at the time.

    In order to use your Apple ID to create an iCloud account, the primary email address associated with the ID must first be verified.  To do this, Apple will send a verification email to your account and you must respond to the email by clicking the Verify Now link.  Make sure you are check the spam/junk folder as well as the inbox.  If it isn't there, go to https://appleid.apple.com, click Manage your Apple ID, sign in, click on Name, ID and Email addresses on the left, then to the right click Resend under your Primary Email Address to resend the verification email.

  • Please help needed os x lion I wish to transfer photos from the iPhoto library to a album or folder then delete them from the Library but when I do this it also deletes them from the album ? how do I do this please.

    Please help needed os x lion I wish to transfer photos from the iPhoto library to a album or folder then delete them from the Library but when I do this it also deletes them from the album ? how do I do this please.

    Albums are not places to store photos, they're more like "labels" you can apply to photos to better organize them. A single image file can be in multiple albums... they are not copies, it's simply been labelled as being in all those albums. So what you're trying to do doesn't make sense, because it's based on incorrect assumptions.
    The iPhoto library will always show all photos that you have added to iPhoto.

  • Text doesn't show, scroll bar does? using Flash CS3 Please help!

    A little background:  I made text box, typed some text, converted it to a movie clip, named etc.  Used a purchased and proven scroller component ... followed directions to the letter, including referencing/linking the files. However, when I tried to test the scroll bar .... the scroll bar appears, scrolls and works perfectly except the text does not appear.  I have tried making a scroll bar with the UIscrollbar same thing happens. I made an other attempt and put pics along with the text in the movie clip ... this time the pics appeared and scrolled, but the text still would not appear.  PLEASE HELP. I am on a deadline and can't get past this scroll bar issue. THANK YOU!

    Hi
    Thanks for the tip. I did embed the text, but still not showing. Currently, I have the text  box set to the following: Dynamic Text, Multiline, Border Around text, Anti-Alias for Animation (but I have tried all choices and embed the text each time).
    Here are the original instructions with the FTscrollbar which I followed exactly.
    1. Drag the component (FTscrollbar) from the components panel to the stage.
    2. Create a new movie clip to be scrolled:
         a. create a textfield on the scene and type in a few lines of text
         b. select the text fields and covert them to a move clip symbol having the registration point top left. (I did top right since my scroll bar is on the right).
         c. give the new movie clip an name in properties panel.
    3.Select the component of the stage and configure its parameters in the parameters panel or component inspector panel.
         a. Instruc the component to scroll the new created movie clip as the targetMovieClip
         b. Set the viewAreaHeight and viewAreaWidth
         c. set snapMode to snapToView value
         d. leave rest of parameters unchanged unless you want to adjust.
    4. Test Movie (contol/test movie)
    On the FTscrollbar, I have the targetMovieClip set to the movieclips name the only other parameters the instructions said to change were veiwAreaHeight=100 veiwAreaWidth=150 which were the defaults.  When I change this numbers the scroll bar goes away and the text still doesn't appear?  The scroll bar is 16 x 140, the text box to be scrolled is 130 x 143 and the entire flash page is 500 x 550. I am not sure what the viewAreaHeight and viewAreaWidth are for ... or if that could be the problem?  I have never had problems with scrollers but I used MX. I just recently purchased the CS3 and I am not sure what I am not selecting or not selecting but if feel it's probably something simple I am overlooking.  So any more ideas are MOST APPRECIATED. If you need more info from me to help solve, please feel free to ask. THANKS!

    I just noticed that I forgot to use an empty stoplist, so I have added that to the revised example below.  Otherwise, it uses a default stoplist that would not index common single-letter words like A and I.
    1. Whtat is Just search on single character 'L'? It give me error.
    Since it uses the NEAR operator, searching for just one letter causes incomplete syntax, asking it to search for L near a missing second value.  So, I have added additional code to allow for just one letter.
    2. How do I do auto refresh on this index on datastore?
    If I add "sync        (on commit)" it does not refresh the previously set token.
    Sync(on commit) does synchronize so that the data is immediately searchable.  You have to either optimize or rebuild or drop and recreate the index to condense the rows in the domain index table.
    3.lastly explanation of
    <seq>NEAR((' || letters_func (:search_string) || '),1,TRUE)</seq>
                      <seq>NEAR((' || letters_func (:search_string) || '),100,TRUE)</seq>
                    <seq>NEAR((' || letters_func (:search_string) || '),100,FALSE)</seq>
    why 100 true and 100 false
    100 is just a default value that I used for the second parameter of near, indicating how close the letters need to be to each other.  True and False are values for the third parameter of near, indicating whether or not the letters must be in the same order or not.  So, it returns the results in the order of first those that are very close to one another and in the same order, then those that may be further away but in the same order, then those that may be further away and in any order.

  • Please, Help NEED immediately, Radeon 9200 Ati on 23" hd cinema display??

    Hi you all expert, i definitely need some help here after searching through the site , i still couldn't find the solution. Currently i am operating an old G4 Mac 400 mhz , rage 128 pro, the salesman told me it will support the new 23" hd cinema flat panel display, which he fails me, and after checking up the system requirement the minimum should have been radeon 7500. Anyway, i am contemplating on purchasing a new ati 9200 radeon mac edition (within my budget) and would like to ask if it will support the new 23" hd display sitting in my living room. Please help, thanks a million!!!!!

    You should have no problem with this card running the 23'' Cinema. It will indeed

  • Please help me to search topics. I'm having a problem.

    I am trying to search this forum for a particular topic.
    I type into the box in the upper right hand corner of the page that says 'search forum' (where mini magnifying glass is) and there is nowhere to click on return.
    If I hit the enter key on my keyboard nothing happens.
    I am using IE and I tried Firefox with no luck.
    I even killed the page and then logged back in to see if that helped.
    I have searched forums in the past with success but I cannot figure out what I am doing wrong.
    Please help.
    Thanks!

    I tested the 'search' and all I did was enter the topic and press enter/return, and it searched. try closing your browser and restarting it.

  • Please Help,I made new account then remembered old one.need to delete new

    Please Please help . so complicated . ok i had an apple id but couldn't remember id n password so i made a new one . old one has all my music . old one has an old email that i can't access . after i made new one i remembered the old one . i want the old one cause it has alot of purchased music on it . thing is , my current email is now assosiated with new id . cant use same id with both so i need to delete new account so i can add my email to old account . How in the world do I delete the new apple id ? Please help me

    This is a user-to-user forum. Nobody here can delete anything for you.
    But - even if you contacted apple/itunes, I don't think they will delete it, either. Just don't use the new one, is my advice. It's a huge hassle over the years to have to remember the login credentials for 2 accounts.

  • Please help - simpleviewer slideshow and text link to start that slideshow

    I have iweb 1.1.2
    I have made a simpleviewer folder (done from a CS4 script on the simpleviewer website).
    I don't like the horrible "start slideshow" button, and would rather have a text button/link (e.g., "start slideshow" in a font of my choosing) that begins the simpleviewer slideshow, not the default iweb slide show.
    Can anybody teach me how to do this in very simple english, like you're talking to a 5 year old, because that is the intellect of my web experience?
    Thanks so much.

    Anyone? Please help?

  • Please Help Urgent:Fast Search returning wrong result sets

    Hi All,
    We are facing below issue with fast search.
    Currently in My project  when  we are searching  for a phrase it is returning wrong result sets.
    For example if we search for “Endura”, It is returning documents related to
    Endura  as well as Centura.
    But the expected results are only Endura documents.
    When we look in to the documents we didn’t find the search term (“Endura” ) either inside document content or in its meta data.
    In order to resolve the issue we tried the below steps
    1-     
    We manually edited and saved the document, to ensure the appropriate Guid association to metadata.
    2-     
    Index reset
    3-     
    Full crawl
    But no luck  so far.
    Please help.Thanks in advance.
    Regards
    Subrat

    Subrat,
    This may be related to spellchecking or may be synonym. Spellcheck is based on indexed terms.
    The best test would be to run the queries from qrserver (13280) and then look at the spellcheck query transformations. If spellchecking is not doing it, then you must have a synonym setup .Check your keyword/synonyms from the SharePoint side.

    Good luck, but they will tell you the same thing that anyone here will tell you.
    Unless the device was backed up (via iTunes or iCloud) after the pictures were taken but prior to deleting them on the device, they are gone.  There is no way to recover them once deleted without a backup.
