Word search image

Hi guys,
This one's quite advanced...
I'm working on a online book project that takes a .pdf,
converts each page into a JPEG and stores them to a unique folder.
I have created a flash file that the user is directed to upon the
.pdf's upload which detects via a querystring, the folder location,
and total number of pages. This, as you have probibly guessed, is
the online book, which has all the bells and whistles of page turn
animations, a goto page function etc...
My problem is this:
I need the application to have a word search function. I know
that ideally the .pdf would have been converted to text, but I
couldn't as the layout of test to images was nowhere near perfect
on the tests I ran.
Is there any OCR styled approach that I could use in flash? I
have created JAVA applets which have performed this task before,
but never within a .swf.
An option is to install an OCR program on the server which
will run dynamically after the .pdfs upload, and store the text
into a database, however, at best (I assume), this will only allow
the user to be taken to the page, and not the line, let alone
creating a transulcent highlight, for example, over the top of the
text.
I don't expect an answer, but any feedback would be geatly
appreciated.
Thanks in advance,

I don't know the answer for OCR. I would be inclined to try
investigagate ways to avoid it that would involve loading the the
content into a swf format...e.g. like flashpaper... or search for
some other way to convert the pdf to swf whilst retaining the
formatting/appearance.
The flashpaper API has for example text searching capability
built in - I'm just not sure how much of the interface you can hide
(or may not be permitted to via the licencing agreement). And if
necessary then its also possible to use bitmapData copies of a swf
format if you need to manipulate it as an image once the swf has
loaded.
Of course if the original source is bitmap you would still
need to adress the OCR problem. Don't know if that helps.

Replace words with images, in a table, using the search/replace tool

Hello everybody
I have a question:
Is it possible to replace words with images, in a table, using the search/replace tool?
My case:
I have a table with about 9000 articles on about 400 pages. In this table there are words which I like to replace with Logos.
Example: The word "DM" should be the Logo "DM" (.eps). This word is about 1200 times in this table.
Is it possible to replace it automatically?
Thank you very much for your helb.
Kind regards Alex

Can you filter/search images before importing them?

Is there a way to filter images before importing them in Lightroom?
Scenario
I work with an extensive image collection stored on a server. The images contain a full set of metadata, including keywords and more. When I work on a specific project, I import the images into a Lightroom collection. That way I can easily review, rate and add additional keywords to those best-of images.
The challenge is that the images I want to add are from numerous folders. Plus, I often only want to add some images from those folders (not the entire folder). This collection process can be very time consuming -- manually locating the images and checking/unchecking the ones I want and repeating the process for the different folders the images reside in.
The process could be greatly simplified (and a lot faster) if I could filter/search for images that contain key words or other metadata to find the full set of images I want to import.
The key is that I’m not using a workflow to simply import all images from a memory card or download folder. I’m working from a large collection of existing images and want to import a subset of those images.
Thanks in advance.

No, you cannot filter or search images before importing them.
But immediatley after import the images are automatically displayed in <Previous Import>.
They will be displayed there until you import another set of images.
While displayed in <Previous Import> they can be searched and filtered.

Covering text on Word Search widget

Hi,
I am using the word search widget and ther is some faint text on the bottom that saus "click the first then the last letter of the work to ma e a selection"
I am trying to get wrid of that so I can put the instruction text elsewhere on the slide, but the words stay visible, even over some buttons we have got in the fram. Sending to bck doesnt work either. I have also tried covering the text with an image (of background), thenm grouping the widget with the image on front, but then that covers the buttons, even if I use send backwards...
Is ther a way if editing that instruction text so I can get rid of it?
Cheers
Rossco

Hi Rossco
I saw your replies only now as I am in India. Glad that you figured out a way.
To answer your question on how to assign an image to smartshape, you can go to Fill and Stroke accordion and click the Fill dropdown list. Here you have an option to browse and select a custom image.

Cptiavte 8 - the actions does not appear in proprerties when adding a word search widget - any clues please

Are there some bugs in captivate - the properties do not always show timings - is this the same for Actions on a word search widget?

I understood perfectly your question. There is barely documentation about the learning interactions. I have been presenting last year at DevLearn about them with great success, but this year that presentation (even a workshop would be useful) was declined. And I never see any tutorial about them, no documentation in the Help etc. Wondering why, because they offer some time saving functionality to make a course more engaging. In my last blog post I showed how the Scrolling TextArea Interaction (as widget it is called TextArea, name that is still visible for the interaction as well???) can be used for a Short Answer question with more functionality than the default one: Custom Short Answer Question - Captivate blog
There is already the big confusion: why are there Widgets (they still are included) and Learning Interactions that both are pointing to widgets (hence the generic name), just to make the difference between those widgets that are SWF only and those that are compatible also with HTML5 output (the so-called Learning Interactions or Interactions)? Terminology is to say it very diplomatic, bit 'inconsistent'.
But what I explained in this blog post about Widgets, the 3 categories, is also valid for the Learning Interactions: http://blog.lilybiri.com/using-captivate-widgets-some-tips
You will see that static widgets cannot trigger Actions! Only the interactive widgets (and question) can do that. It is the same difference that exists for objects: non-interactive objects like text captions, images, cannot have actions attached to them, only the interactive objects (buttons, click boxes, TEB's, shape buttons). There is one hybrid object, the rollover slidelet. The Interaction you are pointing at, Word Search, is a static interaction, which means no actions and thus the Actions tab will not appear!
Another blog post shows all the events that can trigger an action: Events and (advanced) Actions - Captivate blog
As for your second question: in Captivate 6 all interactions were pausing at the first frame, and that caused a lot of problems (audio not playing is one of them). For that reason the behavior changed radically from 7 on: now they are not pausing at all. That means thaty you need to insert an interactive object with a pausing point like a button (think about a Next button?), click box, shape button...
Oh yes, static widgets cannot have score attached to them, there is no real way to check if the WordSearch widget has been used? It is an exception, because the other game interactions have an associated variable, are interactive, can trigger actions and can have a score (but that is another long story).
Think I have spent already too much time answering, to try to fill in the gaps in the documentation. I could write multiple articles on Interactions, want to provide more information but free things are not considered valuable at all. Why should I bother

10G-form: How to do MULTIPLE WORD OR SINGLE WORD SEARCH at ITEM?

I am using 10G DB + 10G Form Builder.
I've 'database_item' where I am storing multiline text data.
I want to do MULTIPLE WORD OR SINGLE WORD SEARCH at this item through FORM.
I've tried by creating the following NON Database Items on the form:
- multiline_search_text_item, and
- multiline_result__text_item
And then writing execute_query in KEY-NEXT-ITEM trigger.
I've also tried using this in the POST-TEXT-ITEM at multiline_search_text_item:
select table.database_item into :multiline_result__text_item from table where multiline_search_text_item = :multiline_search_text_item;
Pl help me asap.
Gaurav

What you want to do is not clear.
The query you wrote will select records where the table contains exactly what has been written in the search item. You can use LIKE and a wildcard search to find records which contain the search text:
select table.database_item into :multiline_result__text_item
from table
where multiline_search_text_item LIKE '%'||:multiline_search_text_item||'%';
You can use UPPER to make this case insensitive:
select table.database_item into :multiline_result__text_item
from table
where Upper(multiline_search_text_item) LIKE Upper('%'||:multiline_search_text_item||'%');
But I suspect you want either to match the individual words in the search text to individual words in the database multiline field, or find records where the search words appear (not necessarily as whole words). In that case, check out the following:
-- set up a table (multiline and various whitespaces)
DROP TABLE t;
CREATE TABLE t AS
SELECT
ROWNUM rn,
owner||Chr(9)||object_name||Chr(160)||subobject_name||'    '||object_id||' '||
data_object_id||Chr(10)||object_type||' '||created||' '||last_ddl_time||' '||
timestamp||' '||status||' '||temporary||' '||generated||' '||secondary AS col
FROM all_objects;
-- check the format of the multiline text item (col)
SELECT * FROM t WHERE ROWNUM < 4;
-- a type for the function below
CREATE TYPE string_tab AS TABLE OF VARCHAR2(255);
-- this function takes a string and cuts out each word, idetifying words
-- as being separated by any whitespace. it returns a collection
CREATE OR REPLACE FUNCTION string_to_tab(
p_string IN VARCHAR2) RETURN string_tab IS
l_string LONG DEFAULT
    RTrim(regexp_replace(p_string,'[[:space:]]+',' ')) || ' ';
l_data string_tab := string_tab();
n NUMBER;
BEGIN
LOOP
    EXIT WHEN l_string IS NULL;
    n := InStr(l_string, ' ');
    l_data.extend;
    l_data(l_data.Count) := LTrim(RTrim(SubStr(l_string, 1, n - 1)));
    l_string := SubStr(l_string, n + 1);
END LOOP;
RETURN l_data;
END string_to_tab;
-- selecting from t where ANY of the words in the search text has
-- a match in the multiline field (as a word or part of a word), so SYS
-- matches to MDSYS and SYSTEM
SELECT DISTINCT
t.rn, t.col
FROM
t,
(SELECT column_value
   FROM TABLE(CAST(string_to_tab('SYS   INDEX') AS string_tab))) x
WHERE InStr(t.col,x.column_value) > 0;
-- selecting from t where ALL of the words in the search text has
-- a match in the multiline field (as a word or part of a word), so SYS
-- matches to MDSYS and SYSTEM
SELECT rn, col FROM(
SELECT
t.rn, t.col, cnt_x, Count(*) cnt
FROM
t,
(SELECT column_value , Count(1) over(PARTITION BY 1)cnt_x
   FROM TABLE(CAST(string_to_tab('SYS   INDEX') AS string_tab))) x
WHERE InStr(t.col,x.column_value) > 0
GROUP BY t.rn, t.col, cnt_x
WHERE cnt = cnt_x;
-- selecting from t where ANY of the words in the search text
-- match a word in the multiline field, so SYS matches only to SYS
SELECT DISTINCT
t.rn, t.col
FROM
t,
(TABLE(CAST(string_to_tab(t.col) AS string_tab))) t2,
(SELECT column_value
   FROM TABLE(CAST(string_to_tab('SYS   INDEX') AS string_tab))) x
WHERE t2.column_value = x.column_value;
-- selecting from t where ALL of the words in the search text
-- match a word in the multiline field, so SYS matches only to SYS
SELECT rn, col FROM(
SELECT
t.rn, t.col, cnt_x, Count(*) cnt
FROM
t,
(TABLE(CAST(string_to_tab(t.col) AS string_tab))) t2,
(SELECT column_value , Count(1) over(PARTITION BY 1)cnt_x
   FROM TABLE(CAST(string_to_tab('SYS   INDEX') AS string_tab))) x
WHERE t2.column_value = x.column_value
GROUP BY t.rn, t.col, cnt_x
WHERE cnt = cnt_x;For your application you would replace 'SYS INDEX' with a variable (the search field). You can use upper() and wildcards for case insensitive & 'fuzzy' searches. You might need to modify the function so it removes other delimiters such as commas and colons.

How do you perform partial word search using PDF Open Parameters?

Hello,
We are using the 'search=' open parameter in the URL string, which open a PDF and automatically searches for a word within the PDF. It works great for whole word searches. Unfortunately, it does not work for partial word, or phrases. In other words, if I'm searching on '123456' and there is a word in the document that is '1234567', it will not find the partial word, or first 6 characters of the 7 character word. You can perform a partial or phrased search using the advance search feature of Adobe Reader. So, currently after the PDF opens, and shows no hits on the automatic search for '123456', we are able to manually search again for a partial word search, and then see matches in the document. Is there any way to specify to use a whole or partial word search when using the 'search=' open parameter, so that we can automatically match on partial and whole words? Something like 'search=123456*'?

It never worked that way. Command-F shows the page search bar.

Sometimes, when I click on a link, I see in the address bar the words: "Search bookmarks and history" (greyed out) just before I am taken to the link. Should I be worried? Is someone searching my personal data? Is this just a FireFox error msg?

Sometimes, when I click a link on a web page, I see in the address bar the words: "Search bookmarks and history" (greyed out) just before I am taken to the link I clicked. A moment later, when I'm at the link, its address appears in the address bar, and all is normal. It seems that this happens only from some particular sites. Is FireFox reporting that my bookmarks and history are being searched?
Should I be worried? Is someone searching my personal data? Is this just a FireFox error msg when it has trouble finding the website I requested?

That is OK. Firefox will only display the link in the location bar after the DNS look up has succeeded and a connection to the server has been established. Until that has been done you see the default setting for the location bar: Tools > Options > Privacy > Location Bar: When using the location bar, suggest

My iphone 5 has the word searching in the upper left hand corner for 3 days. I can connect to the net , but no phone service. What is possibly wrong?

WHy cant i get phone service? The word " searching " has been in the upper left hand corner for 3 days. I have internet service but no phone service. Does any one have any thoughts or suggestions?

When you say you have Internet service, are you connected to wifi? Have you tried a reset on the phone? Hold the sleep/wake and home buttons together until you see the Apple logo, then release. The phone will reboot. After it starts, see what happens. Do you have a valid SIM in the phone, one that is activated through a carrier? Have you contacted the carrier to see what they say, since phone service is a carrier responsibility?

Whole-word search in project

I'm running RH for HTML Help X4.1 on Windows XP. I want to
search through all the text in all of the topics for a particular
word or word string. Is that possible? I can't find anything that
lets me do that? I realize this is NOT Win Help where I'd be
searching a Word document, but it would be very helpful to be able
to do a whole-word search of the project. Thanks.
-david

Just a word of warning. It is good practice to close your RH
project down as the in built tool does occasionally fail to spot
instances in open topics/projects. Personally most authors on here
prefer to use other tools (e.g.
FAR or
BkReplacem).

CF perform word search on PDF files?

Can CF MX (6.1 or 7) perform a word search of PDF documents?
What I would like to do, at the minimum, is have CF search
PDF files located in a directory for a specific word, and return a
list of files that have that word (or phrase) in them.
am I asking too much?
Thanks for any and all help.

Yes. Use the Verity search engine that comes with
ColdFusion.

Simple Word Search

Hi all wonder if you can help me. I'm trying to write a little word search style game in java swing. However i'm a little confused as how to start. I want to be able to draw a grid with letters manually placed in it, so something like this:-
a b c a b c d e f
h e l l o w o r l d
a b c a b c d e f
a b c a b c d e f
I want each grid square to have a specific x and y co-ordinate so say h in the grid above would be at co-ordinate [1,1] and e would be [1,2], etc.
If someone could give me a bit of advice on how to get started on this, i would be most grateful!
Regards
Vince

Use a JPanel with a GridLayout and add JLabels to each grid.

Topic Not Showing in Word Search

Hi there,
I have an important Topic that I need to show in my word
search results, but it does not. As well, the Topic does not come
up when I click on it in the Index.
I have verified that the Key word is in the title of the
Topic I wat to show up. Any ideas what is causing this or how it
can be fixed?

Welcome to the forum.
Can you access the topic in any way? I am wondering if you
have excluded it with a build tag.
