Adobe Acrobat Reader Plug - Writing to text file

Hi,
I have an Acrobat plug-in which performs various functions including writing to a text file on c:\
If I use my plug-in with Acrobat all is well.
If I use the same plug-in with Reader everything seems to work ok except that it won't create the text file. It's as if Adobe reader is protecting this somehow.
Has anyone seen this before? Any one know how to get around it?
Regards
Stuart

More about protected mode. It is designed specifically to protect the user against attacks originating INSIDE Adobe Reader (e.g. via exploits). Sandboxing is a leading edge protection technology, which (for example) is also being applied to browsers. Your plug-in is therefore part of the problem to be protected against. You have to fully understand the philosophy to exist inside this new sandboxed world. Here is some reading

Click on download of pdf opens adobe acrobat reader, but then clicking on file save-as does not give a dialog box to change the name or location where it is sav

Using Firefox 19.02
When I receive an email with an Excel, Word, or PDF file attachment, and I click download, firefox opens up the associated program for all my users, however when you click on file>save-as you are not presented with the dialog box to perform a save.
Excel and Word, no fix at all. Other than different browser or to click download, right click and go to folder, and then copy it out of there to another folder and open it.
Help, what is going on here????

BTW: using Adobe Acrobat Reader XI

Repeated notification that "Adobe Acrobat Reader plug-in" in Firefox is "out of date" after the upgrade is downloaded and installed.

I have tried to update the Adobe Acrobat Reader DC, along with the plug-in in Firefox v37.0.1. Repeatedly, after the download/installation is "complete", upon opening Firefox I'm met with the message that the "Adobe Acrobat plug-in" is "out of date". I tried rebooting my machine, uninstalling Acrobat Reader DC (which works as a stand-alone), and still the plug-in is never updated (the one listed is from early December 2014) and the reminder always reappears with opening Firefox. Can anyone help with this?

Sorry about the issue which you are facing. It would be helpful if you could share the firefox notification message screenshot.
Also, please check that the firefox plugins show the correct Adobe Acrobat Reader DC plugin. If possible, please share the firefox plug in screenshot as well.

Need Help: UTL_FILE Reading and Writing to Text File

Hello I am using version 11gR2 using the UTL_FILE function to read from a text file then write the lines where it begins with word 'foo' and end my writing to the text file where the line with the word 'ZEN' is found. Now, I have several lines that begin with 'foo' and 'ZEN' Which make for one full paragraph, and in this paragraph there's a line that begins with 'DE4.2'. Therefore,
I need to write all paragraphs that include the line 'DE4.2' in their beginning and ending lines 'foo' and 'ZEN'
FOR EXAMPLE:
FOO/234E53LLID
THIS IS MY SECOND LINE
THIS IS MY THIRD LINE
DE4.2 THIS IS MY FOURTH LINE
THIS IS MY FIFTH LINE
ZEN/DING3434343
FOO/234E53LLID
THIS IS MY SECOND LINE
THIS IS MY THIRD LINE
THIS IS MY FIFTH LINE
ZEN/DING3434343
I am only interested in writing the first paragraph tha includes line DE4.2 in one of ther lines Not the Second paragraph that does not include the 'DE4.2'
Here's my code thus far:
CREATE OR REPLACE PROCEDURE my_app2 IS
infile utl_file.file_type;
outfile utl_file.file_type;
buffer VARCHAR2(30000);
b_paragraph_started BOOLEAN := FALSE; -- flag to indicate that required paragraph is started
BEGIN
-- open a file to read
infile := utl_file.fopen('TEST_DIR', 'mytst.txt', 'r');
-- open a file to write
outfile := utl_file.fopen('TEST_DIR', 'out.txt', 'w');
-- check file is opened
IF utl_file.is_open(infile)
THEN
-- loop lines in the file
LOOP
BEGIN
utl_file.get_line(infile, buffer);
     --BEGINPOINT APPLICATION
IF buffer LIKE 'foo%' THEN
          b_paragraph_started := TRUE;
     END IF;
     --LOOK FOR GRADS APPS
          IF b_paragraph_started AND buffer LIKE '%DE4%' THEN
          utl_file.put_line(outfile,buffer, FALSE);
END IF;
     --ENDPOINT APPLICATION
          IF buffer LIKE 'ZEN%' THEN
     b_paragraph_started := FALSE;
          END IF;
utl_file.fflush(outfile);
EXCEPTION
WHEN no_data_found THEN
EXIT;
END;
END LOOP;
END IF;
utl_file.fclose(infile);
utl_file.fclose(outfile);
EXCEPTION
WHEN OTHERS THEN
raise_application_error(-20099, 'Unknown UTL_FILE Error');
END my_app2;
When I run this code I only get one line: DE4.2 I AM MISSING THE ENTIRE PARAGRAPH
PLEASE ADVISE...

Hi,
Look at where you're calling utl_file.put_line. The only time you're writing anything is immediately after you find the the key word 'DE4', and then you're writing just that line.
You need to store the entire paragraph, and when you reach the end of the paragraph, write the whole thing only if you found the key word, like this:
CREATE OR REPLACE PROCEDURE my_app2 IS
    TYPE line_collection
    IS       TABLE OF VARCHAR2 (30000)
           INDEX BY BINARY_INTEGER;
    infile               utl_file.file_type;
    outfile                      utl_file.file_type;
    input_paragraph          line_collection;
    input_paragraph_cnt          PLS_INTEGER     := 0;          -- Number of lines stored in input_paragraph
    b_paragraph_started      BOOLEAN      := FALSE;     -- flag to indicate that required paragraph is started
    found_key_word          BOOLEAN          := FALSE;     -- Does this paragraph contain the magic word?
BEGIN
    -- open a file to read
    infile := utl_file.fopen('TEST_DIR', 'mytst.txt', 'r');
    -- open a file to write
    outfile := utl_file.fopen('TEST_DIR', 'out.txt', 'w');
    -- check file is opened
    IF utl_file.is_open(infile)
    THEN
     -- loop lines in the file
     LOOP
         BEGIN
          input_paragraph_cnt := input_paragraph_cnt + 1;
             utl_file.get_line (infile, input_paragraph (input_paragraph_cnt));
          --BEGINPOINT APPLICATION
          IF LOWER (input_paragraph (input_paragraph_cnt)) LIKE 'foo%' THEN
              b_paragraph_started := TRUE;
          END IF;
          --LOOK FOR GRADS APPS
          IF b_paragraph_started
          THEN
              IF input_paragraph (input_paragraph_cnt) LIKE '%DE4%'
              THEN

              END IF;
              --ENDPOINT APPLICATION
              IF input_paragraph (input_paragraph_cnt) LIKE 'ZEN%' THEN
                  b_paragraph_started := FALSE;
               IF found_key_word
               THEN

                   LOOP
                       utl_file.put_line (outfile, input_paragraph (j), FALSE);
                   END LOOP;
               END IF;
               found_key_word := FALSE;
               input_paragraph_cnt := 0;
              END IF;
          ELSE     -- paragraph is not started
              input_paragraph_cnt := 0;

SHOW ERRORSIf you don't have an EXCEPTION section, the default error handling will print an error message, spcifying exactly what the error was, and which line of your code caused the error. By using your own EXCEPTION section, you're hiding all that information. I admit, the error messages aren't always as informative as we'd like, but they're never less informative than "Unknown UTL_FILE Error'. Don't use your own EXCEPTION handling unless you can improve on the default.
Remember that anything inside quotes is case-sensitive. If your file contains upper-case 'FOO', then it won't be "LIKE 'foo%' ".

Disabling/Re-enabling Adobe's Acrobat Reader Plug-in

Hi there
I was forced to install Adobe's Acrobat Reader Plug-in in order to view and download my bank statements. However, I would like to use Safari's default PDF viewer plug-in when browsing other than my bank's website.
Is there any way to disable and re-enable the Adobe Acrobat Reader (Plug-in) without having to uninstall Adobe Acrobat Reader?
Thanks in advance.
Message was edited by: another_steve

I had the same issue with 9.0.0 -- option to disable from Reader's "Internet" options was grayed out.
This is a side-effect (feature?) of how Adobe installs the plug-in at the System level
/HD/Library/Internet Plug-Ins
instead of at the User level
~/Library/Internet Plug-Ins
I switched to an Admin account, launched Reader, and the option was not grayed out. I deselected it then quit and switched back to my user account.
When I launched Reader in my user account and opened preferences, then selected Internet, the option was still grayed out but now the "feature" was disabled.
So, Adobe has decided that individual users don't merit control over their own plug-in preference. It's the admin's choice and that dictates for all users on the system.
Like you, there are only a few situations where I am forced to use Adobe Reader -- certain medical, insurance, or financial forms that don't render or transmit accurately when using Preview.
Drives me nuts -- those are exactly the kind of forms I want to save as PDF to disk when completed -- and Adobe explicitly prevents saving as PDF. I can transmit the completed form to the provider, or I can save a blank form, but I cannot save a PDF of the completed form. Like chewing on soap by the time I'm finished...
Anyhow, hope that sorts it out for you.

Installing Acrobat Reader Plug-In Only (Not Full App)

I'm curious to know if its possible to load the Adobe Acrobat Reader Plug-in portion only in IE and Firefox. Ideally I'd prefer to not have to install the entire application just to view PDF's in IE/Firefox as I rely on a third party application to view, and manipulate, PDF's outside of the browsers. Yes, I can change the association of .PDF's in Explorer or re-install (or perform a repair installation of) the application to restore the file associations, but if I can avoid installing Adobe Acrobat Reader all together, I'd prefer that route.
Is this possible or does the application have to be installed?
Thanks
Jules

It needs to be installed.

See if you can find a NPPDF32.DLL files in the Firefox program folder (C:\Program Files\Mozilla Firefox\)
You can see the installed plugins on the about:plugins page.
* http://kb.mozillazine.org/about%3Aplugins
You can set the pref plugin.expose_full_path to true on the about:config page to see the full path of plugins on the about:plugins page.
It is best not to leave that pref set to true as it exposes that full path to web servers, so reset that pref to false after you are done with the about:plugins page.
You can open about:plugins and about:config via the location bar, like you open a website (about: is a special protocol to access some build-in pages).
If you get a warning when opening the about:config page then you can confirm that you want to continue.

None has solved the problem. However it still works ok with IE. But I want to stick with Chrome because I find IE is so slow!
I am using Vista, with Adobe Acrobat standard 9.5.2 and Google Chrome version 23.0.1271.64 m which is marked on Chrome as 'up to date'
Does anyone know why I might be getting this error on Chrome but not IE?

I think I have discovered the answer to my own question!
I have disabled Adobe Reader plug-in, and can now see PDFs in Chrome.
(Steps: Chrome Menu, Settings option, Click Advanced Settings link, then Content Settings button, then select Disable Individual Plug-Ins, and a list of plug-ins is offered to enable or disable).
I then get a different result depending on whether or not Chrome PDF viewer is enabled - with it enabled I see the PDF document in Chrome, or with it disabled then the option is offered to download it, but either way I can get it it via Chrome without having to run Internet explorer in another browser window.

The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. Please exit Adobe Acrobat/Reader and exit your Web Browser and try again.OK. I followed the instruction and the problem still persists.

I got the following pop-up when I tried to open an online PDF file:

Please exit Adobe Acrobat/Reader and exit your Web Browser and try again.
I tried many time, and it really doesn't work.
The plug-in I have is Adobe Acrobat 8.3.0.280

After I upgraded to Firefox 5, I had the same problem and I did a work around temporarily. I went the tools menu, then Add-ons, then clicked the "Plugins" on the left side (4th one down). I "disabled" both Adobe Acrobat 8.3.0.280 and Adobe Acrobat 10.1.0.536 using the disable buttons on the right side. PDF files now open again. However they are outside the actual browser.
My guess is that Adobe didn't catch up yet with a new update to work with Firefox or vice versa.
Hope that helps!

Adobe Acrobat X Pro writing text not smooth.

I use tablet pc for education in university and I try Adobe Acrobat X Pro writing text it not smooth text can you have add-in pen input support or support pen writing (smooth)for tablet pc?

If you want to annotate the PDF directly on a tablet, use PDF Annotator. The annotation capabilities of Acrobat are poor. You also have to select the erase tool to erase, rather than just turn the pen over. PDF Annotator works the way you would expect annotation to work with a pen. It is also useful if you grade PDFs on the tablet. The only thing I find annoying with Annotator is that the paging is a bit clunky. You should be able to find an educational price for the package, or possibly your school has it under license. There is a 30-day trial if you would like to try it. Most folks here would not dream of annotating with Acrobat for the same reasons you have found.

Cannot input data into Text Field on from Adobe Acrobat Reader

I created a form in Acrobat 5 that has check boxes and text fields. Using reader I can open the doc and use check boxes and input text into fields. Once this doc is loaded to our web server and a user opens or downloads the file they can check the boxes but cannot enter any text into the text fields. Am I missing something?
Thanks in advance

And so.. what is invalid?
I've uploaded the pdf files as example:
My generated pdf
http://compuhelp.free.fr/adobe/before.pdf
The modified version by Adobe Acrobat Reader:
http://compuhelp.free.fr/adobe/after.pdf
(I can generate a more complexe pdf file with fonts, images,... it will be displayed correctly, but Adobe always want to modifiy it).
So perhaps I missed somthing into the pdf file format specification ?

Hi
I've a big problem with adobe acrobat reader XI pro and I hope you can help me.
The problem is; when I past copied text from some pdf books (not all of them) it past symbols only! wherever I past it! and even if I coped that text from another pdf reader (adobe pdf reader, internet browsers, ...etc.).
This problem started to happen since yesterday when I installed adobe acrobat reader XI pro to try it before I buy it, and before that when I was using the free adobe pdf reader I was totally able to copy any text from any pdf and past it anywhere with nothing wrong.
What can I do?
thank you a lot.

There is no product called Adobe Acrobat Reader Pro. There is
- Adobe Acrobat Pro ($$)
- Adobe Reader (free)
Which do you have? And are you a programmer?

What's the name of the file you are attempting to open? Is it "ScreenFlow_4.5.2.dmg"? If it is the correct name then the message is correct and you are attempting to open a file with DMG files extension and not one with a PDF file extension. Adobe Reader opens PDF files an not any other file type.
