SDK: COM class works in Acrobat, fails in Acrobat Reader

Hi all

I'm developing a plug-in for Acrobat and Reader.  He works in Acrobat, and I activated successfully drive the API.  The menu options are showing correctly, but when I try to use my COM class, I get an error.

For this test, I simply shows a screen about with single button. The class is registered correctly because it works in Acrobat. Here is a code snippet:

HRESULT hr = CoInitialize (NULL);

If (SUCCEEDED

{

DURING THE

IAboutPtr pIAbout (__uuidof (About));

I get a crash on the last line. He tries to define the pointer, but I get an Access Exception. The class is here and can be found (and works) when it is running in Acrobat. What is different in Reader that would cause this to fail?

Thank you

Mark

  • Is it possible to make the buttons work in Acrobat Reader for iPhone and iPad?

    Hello

    I shopped in the forums, and although several threads are on the same question, I can't find a conclusive answer. I try to open an interactive pdf with buttons (show/hide actions) on my iphone in Acrobat Reader. However, the functions do not work, then they work fine on my Mac. Am I right in thinking that it is impossible to have buttons in interactive PDF work on my iOS devices? All applications are up to date. The buttons were created in inDesign.

    Thanks in advance for your support.

    Hi jom13880393

    I apologize for the issue.

    However, the navigation buttons options you speak is not available in the app and there is no solution for it right now.

  • Touchpad not working do not since the scroll v16.0.2 upgrade... All other Windows applications are very good. Scroll even works in Acrobat Reader plugin in Firefox.

    Tried to roll back to an earlier version without result. Seems that the new version has brought permanent changes to the system.

    Have you checked on the Web site of the manufacturer if there is an update available for the driver for the touchpad?

  • Acrobat Reader DC fails on CommandInvalidContextError when submitting PDF document on server

    We have Flex application that opens the PDF in document IFRAME and allows the user to fill out the PDF form, add the signature and removing the PDF on the server.

    HTML fragment:

    <object CLASSID="clsid:CA8A9780-280D-11CF-A24D-444553540000" id="myPdf" border="0" width="100%" height="100%" 
         type="application/pdf"
         standby="Loading pdf...">
         <PARAM NAME="src" VALUE="downloadDocument.do?docId=12345">
         <p>Error Loading PDF.</p>
    </object>

    When the user submits the PDF following the code JavaScript is executed on the server.

    function submitPdf(url) { 
         var params = new Array(3);
         params[0] = "Submit";
         params[1] = url;
         params[2] = "PDF";
         var ar = document.getElementById("myPdf");
         ar.messageHandler = {
              onMessage : function(msg) {
                   window.alert("Success...");
              },
              onError : function(error, msg) {
                   window.alert(error);
              }
         };

         ar.execCommand(params);
    }

    URL is the Manager server that receives PDF data and records them in the database. Client is already connected to the application and is valid JSESSIONID cookie.

    Everything works with Acrobat Reader 10, but after the installation of the new Acrobat Reader DC 2015 we get CommandInvalidContextError exception.

    No one knows what to do to get the job of action submit or how call plugin Acrobat Reader properly APIs?

    No, the URL contains only 7-bit ASCII characters. This cannot be a cause of this problem, because the application works fine with Adobe Reader 10 or 11.

    But I finally found a solution.

    We had to upgrade to the latest version of Adobe Reader DC (in the main menu of the application--> help-> check the updates).

    Published in June 2015 2015.008.20082 update. This continuous update provides security mitigations and bug fixes.

    It is possible that our problem is related with this release notes.

    I hope that this solution will be included in the next major update in the basic installation.

    Thanks for your help, everyone!

  • Adobe Acrobat Reader 2012 a scam or for real?

    I received an email from [email protected] offering from Adobe Acrobat Reader 2012 which is supposed to have the ability to create and edit files PDF.

    Provides this link: http://www.2012-Acrobat-online-upgrade.com/

    When you click on the download button, it first calls for her e-mail, then asks to credit card.

    And there is a disclaimer below, clause that says: "this site that no affiliation with the owner of this software and provides only a link to the software.» Copyright 2012. All rights reserved.

    If it is a scam, please Adobe to issue a warning, because the offer is tempting.

    Yes. Scam. Easy to spot because there is no such thing as Adobe Acrobat Reader.

  • Contact ID not working-message saying failed

  • SMTP works, but POP3 fails

    I've been a Thunderbird user for about 8-10 years now, and I use it with multiple e-mail accounts. I met a configuration problem, I've never seen before, and I can't find a solution (so far).

    I changed my ISP broadband from Comcast to the border. With Frontier, of course, I get an e-mail account. I can access and use the account very well via webmail. However, when I manually configured in Thunderbird (configure automatically produces the wrong settings), password authentication will fail.

    When I try the Advanced Configuration, SMTP works, but POP3 fails.

    I contacted the support of the border to check the correct settings. They are as follows:

    POP3: pop3.frontier.com, SSL/TLS, Port 995
    SMTP: smtp.frontier.com, SSL/TLS, Port 465

    I use the full email address for the user name. He checked the password on the POP3 server, and that's okay. I also disabled my firewall, but it did not help.

    I'm puzzled as to why SMTP should work, but not of POP3.

    They don't support IMAP.

    Any ideas, anyone?

    Your idea to try the iPhone was a good. It also generated the same error, which suggests that it was not a question of Thunderbird after all.

    I ended up calling border once again, and the technology and I ran through everything once more. All the combinations that we have tried has failed.

    Then, on a whim, I suggested that we try to set a different, shorter password.

    The one I had initially set was complex with special characters and about 15-20 characters long.

    We changed it for a subject from 8 to 10 characters long, with special characters.

    It worked.

    Incredible.

    Thanks for your help with this one, Toad Hall.

  • Adobe Acrobat Reader 8 and Microsoft Office word 2007 does not work

    They gave me a laptop Sony Vaio FRO my birthday about a month ago. I work from home, I work online and I use everyday in my computer. The two programs I use the most are gives me a hard time and not let me use a reason any. The software came on the laptop so I called Sony and they told me that it should work fine, and if I have problems to contact microsoft. Well, my point is its does not work and it is causing me loose not being able to work money. Im very frustrated and im desperately need help. Please if anyone can tell me what to do to fix this problem I would be very happy. IM at my wits end here. Acrobat 8 reader telling me I need a serial number to continue using the program and will close and I lose all my work. Also, Microsoft Office Word 2007 again I need a product key number. I use these programs daily to work, I can't cope with this. They keep making me lose all hours of work ive done. Help, please!

    Adobe Acrobat Reader is free, it shouldn't charge for continuous use.  Packages of creator Adobe (Adobe Acrobat Standard, Pro, Pro Extended) cost money.  Microsoft Office is often loaded on a computer as a trial package.  You need to follow up with Sony on these items to make sure if they sent packets of the trial or fully paid packages, and if they are supposed to be freed from the packages that your only relief must come from Sony - we cannot help you here.

  • I reinstall CS4 after failure of hard drive and everything works except Acrobat 9 Pro. I'm under El Capitan on MacbookPro. I reinstalled Acrobat but when I open I only get Word to Acrobat in the finder without options and it does not open.

    I reinstall the CS4 Master Collection after failure of the card logical and all work EXCEPT Acrobat 9 Pro. I'm under El Capitan on a Macbook Pro. The program worked with El Capitan until the logic board failure - I use it every day.  I reinstalled the entire Collection, but when I open I get that Word to Acrobat in the finder without other menus - the application does not open. As a first step, I get an error message.

    Acrobat has detected there are missing components

    Adobe Pdf Finder

    Adobe PDF Viewer plug.

    I tried to uncheck the boxes, but no difference.

    How can I get an operational program again? If Acrobat Pro 9 is no longer supported, how to get a version supported by software that works on my computer?

    Thank you.

    Thanks for the explanation. I actually have to install Acrobat and it now works. I downloaded and installed Adobe Reader XI (I think, http://ardownload.adobe.com/pub/adobe/reader/mac/11.x/11.0.02/en_US/AdbeRdr11002_en_US.dmg ) and opened the program. I noticed that after I opened the new drive, my Adobe Reader 9 program began to work. After that, I tried to open Acrobat and instead of getting the error 6 message that I had before, I had an error on a question of license that would require me to uninstall and reinstall the software. Once I did these steps my Adobe Acrobat 9 Pro started working! Don't know why my program, but it is fully functional again. I hope it helps someone else, I have why I came to answer.

  • The installation of Acrobat Reader program does not work

    I tried Chrome, Firefox and IE. I tried turning my Microsoft Security Essentials to offshore; turn off my Windows Firewall. Nothing works. I am running Windows Vista 64-bit. I followed the online instructions for installation on an earlier version of Windows, but when I get to direct download, there are so mnay different files, and I have no idea of this file to download. Always the same thing happens. I have download the installer, then will have to run two times, and then Windows authorization. and the downloader, it is, never download. And it will sit there for hours doing nothing. I even left it for several hours because I know from experience that these facilities can take some time. I'm just at the end of my mind and need your help.

    Hi Cyndi Stines-MacAfee.
