To store PDF into BLOB and retrieve into OLE/OCX

We would like to:
1. Store a PDF file (output of a report saved in file server) into a BLOB
column.
2. Retrieve previously stored PDF in the BLOB column and display using either
OLE automation or ActiveX (OCX) control.
I read all related documents in metalink that addresses this issue however cant
get this to work. We have Acrobat Reader 4.0. Here are some issues from the
tests that I did:
1. To load the PDF file the program code that uses BFILE and LOADFROMFILE does
not work since the database is on a remote server and the PDF file is on a
local file server. The DIRECTORY created on the database is unable to find the
PDF file.
2. Though I want the loading of the file to be programmatic, I tried
right-click on the OLE container and inserted object from file. This loaded the
file into the container (Icon on the container appeared) however I was not able
to view the document by double-clicking. An error in Adobe occured: 'There was
an error opening this document. A file read error occured'. My guess is the
'Insert Object' did not insert the file properly into the BLOB.
3. When trying to display the PDF file stored in file server (in case storing
into BLOB does not work), I used an OCX control, right-clicked and Insert
Object and select Adobe Control for ActiveX. The problem here is when I run the
form, the OCX control shows up empty and I have to 'Insert Object' again in
runtime. Once I manually insert object from runtime the GET_INTERFACE POINTER &
SET_PROPERTY works fine is displaying the document. Is there any way to
maintain the control property of the OCX when the form is run?
4. Are there any workarounds and better solution to store PDFs into BLOBs and
retrieve and display in OLE/OCX controls? Using temporary file into local drive
is not an issue.
5. Would I be able to make use of 'PDF.PdfCtrl.1' OLE class?
6. Does OLE automation work for Acrobat Reader 4.0.?
I would appreciate all the help.

Im facing a similar kind of problem. I want to store and retrieve Office files, PDF and Jpegs into/from the database to view them on web in disconnected mode. Please reply as I cant find any help/documentation regarding saving BLOB data into files. I was able to store file data into BLOB, using DBMS_LOB package.

How to store pdf into blob, index it and search it?

I am trying to store pdf into a column, index the column and search it.
I store pdf file into blob column with either the following code or with an interface in apex
declare
Dest_loc BLOB;
Src_loc BFILE := BFILENAME('DIR_TESTCASE', 'intermedia.pdf');
BEGIN
INSERT INTO pdffiles(id, description)
VALUES(1, 'InterMedia Concepts')
RETURN text INTO Dest_loc;
DBMS_LOB.FILEOPEN(Src_loc, DBMS_LOB.LOB_READONLY);
DBMS_LOB.LOADFROMFILE(Dest_loc, Src_loc, dbms_lob.getlength(Src_loc));
DBMS_LOB.FILECLOSE(Src_loc);
COMMIT;
END;
then i need to create an index
begin
ctx_ddl.create_preference('pdf
lexer', 'BASICLEXER');
ctx_ddl.set_attribute('pdf_lexer', 'printjoins', '_-');
end;
create index PDFFILES_TEXT on PDFFILES(TEXT) indextype is ctxsys.context
parameters ('lexer pdf_lexer');
sqlplus says index created but windows gives an error and closes ctxhx.exe
and of cource when I tried to make a search like
select id, description
from pdffiles
where contains(text,'Oracle') > 0;
it doesn't return any results.
My database is 10g XE, I also tried it on Oracle 10.2.0.3 EE

It is possible to store pdf and doc files in a blob column, create a text index, and search them, and display them. However, you cannot expect to just select doc and pdf data directly from a blob column and expect to be able to read it, due to all of the special formatting characters. You need to use ctx_doc.snippet or ctx_doc.markup or some such thing to format it and make it readable. Please see the demonstration below. You can search the online documentation for complete syntax, additional information, and examples.

How to store images in database and retrieve them back to page?

Well I don't know how to store an image file to a database (say MSSQL) from the JSP and retrieve it back whenever needed and put it on the JSP page? Please help me.

I am not sure how to store images in database but what you can do is store the image into particular folder using FileOutputStream and its unique name into the database...and than retrieve it from the folder using that name retrieved from database...

How to Store bollean selection values and retrieve them in runtime?

I have an array of bolleans representing a channel of a device. Now , when the user turns on the channel the selected channel array are supposed to be stored. Now when the user selects device 2 (using a ring function) the list refreshes t5he channel names and resets the bollean array to their default values and the new selection values are to be stored. Now if the user wants, he should revert back to device 1 and can review what all channels he had selected for Device 1. How can this functionality be achieved?

You need to store the boolean array somewhere. I would likely just use a shift register
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Can I store pdf in blob, and still search words in the pdfs?Probably not, no. If you want to search the data inside Oracle, you'll want to look at Oracle Multimedia.I think the correct answer is "not efficiently". :-)Well, there is nothing that prevents you from building Oracle Multimedia yourself and getting similar levels of efficiency. Other than a desire not to invest dozens of man-years replicating delivered functionality, of course.

How to store and retrieve a PDF form to SQL Server from LiveCycle?

My intention is to save a complete PDF form into a database and then later on retrieve this form from DB.
To do this, SQL Server has got two datatypes, image or Varbinary(max). I am able to store a PDF using "Execute SQL Statement"(I have written an Insert statement). Some value is being written into DB as well.
But when I try to retrieve this record using "Query Single Row"(I store the result to a doc variable), the retrieved PDF is of an unknown type and cannot be opened by Adobe Reader.
I am not sure if my approach is correct. Is it possible to store/retrieve a PDF form to/from a DB through LiveCycle?
If yes, please give me some guidance.

hi
am not sure
but u can use the same concept as storing image in db and retrieve..
create a blob column
parse that pdf and store into that column.
again u retrieve the content and via file io make the same name with pdf extension..

Acrobat 5 - Placing PDF into inDesign and Output to Colour Separations are Wrong

Acrobat 5 - Placing PDF into inDesign and Output to Colour Separations are Wrong
I have a 2 Page PDF file from my client which I have to have setup 2UP on 450x320 for Metal Plates for the Press.
I setup my page size in inDesign and Placed each page from the PDF file into the inDesign Document.
Because I need 4 Metal plates (CMYK) I had to check the Colour Seperations for the file by outputting it to a Postscript file with CMYK SEPS and then using Adobe Distiller to turn it into a PDF file for me to view the Seperations.
As I've shown in the screen shot below. The CYAN plate has boxes all around the images in the PDF file which will come out on a Metal Plate.
Compared to the Colour version of the Client's PDF they supplied me, there is no boxes around the images.
I know this is a error with dropping a PDF file into inDesign, outputting to a PS file and then Distilling it to the SEPS. I've had the same problem when I've opened a PDF file that has been distilled in Illustrator and the Artwork is sliced into pieces and uneditable.
Has anyone else found this problem and if so is there a workaround?
I'm using Adobe inDesign CS and Adobe Acrobat Professional Version 5.

Im facing a similar kind of problem. I want to store and retrieve Office files, PDF and Jpegs into/from the database to view them on web in disconnected mode. Please reply as I cant find any help/documentation regarding saving BLOB data into files. I was able to store file data into BLOB, using DBMS_LOB package.

Storing an array of checkbox booleans into preferences and retrieving them

Just wondering how to go about storing an array of JCheckBoxes into a preference and retrieving it. There's 32 checkboxes so if they select, say, 6 of these randomly it should store it in a preference file and retrieve it when the application is loaded so that the same 6 checkboxes remain selected. I'm currently getting a stack overflow error, though.
import java.util.prefs.*;
public class Prefs {
     Preferences p;
     GUI g = new GUI();
     public Prefs() {
          p = Preferences.userNodeForPackage(getClass());
          g = new GUI();
     public void storePrefs() {
          for (int i = 0; i < g.symptoms.length; i++) {
               p.putBoolean("symptoms", g.symptoms.isSelected());
     public void retrievePrefs() {
          for (int t = 0; t < g.symptoms.length; t++) {
               p.getBoolean("symptoms", g.symptoms[t].isSelected());
symptoms is the array of checkboxes in the GUI class. Not sure where I am going wrong here. I can do it with strings from textfields etc but this is proving to be an annoyance. :(
Thanks in advance

        JMenu fileMenu = new JMenu("File");

I am trying to drag and drop one page of a .pdf into another .pdf in Acrobat Reader. I used to be able to drag and drop from one .pdf to another.

I am trying to drag and drop one page of a .pdf into another .pdf in Acrobat Reader. I used to be able to drag and drop from one .pdf to another.

If you could drag and drop pages before, it wasn't in Reader. You no doubt had Adobe Acrobat (Pro or Standard) which shouldn't be confused with Adobe Acrobat Reader. They recently added Acrobat to the name of Adobe Reader so the confusion about which product you had and/or have is understandable.

Im trying to convert a PDF into an excel document and I keep getting an error message that reads "An error has occurred while trying to access the service". WHat am I doing wrong?

it seems my subscription had expired so I signed up again.. It was still having trouble so I repeated the sign up process again.. Then it worked perfectly.. Unfortunately, I think I just subscribed twice and need to cancel one of them. Ugh. Such a pain when I'm trying to get this project completed. I'll be canceling at least one of the subscriptions in the morning. Adobe is not my favorite company right now. None of this was intuitive. And trying to get help was an absolute waste of an hour.
