Signing .hlp files

Is it possible to digitally sign a .hlp file? We would like to avoid getting an “Unknown Publisher” message when we open a .hlp file from a network share.
Thanks!

Welcome to our community, Bonnie
I think you'll find the same (or dearth of) answers here on the Adobe forums as you found on TECHWR-L.
WinHelp files are really old technology. Microsoft really tried to fool everyone into thinking WinHelp was dead when they released Vista. Of course it still works under Vista and Windows 7 and may require an additional download to make it work depending on whether it's 32 or 64 bit, but work it still does.
However, digitally signing a HLP file is likely something you will find doesn't exist. And it's quite logical if you think about it. As you are still using .HLP format, you are now among a very small minority of users. To create something like a digital signature and make it work would require an investment of time and money. And since this format is dying, I'd be very surprised to see anyone putting any real effort into something with zero payback.
Cheers... Rick

  • New version no longer generates .cnt, .fts, or .hlp files?

    Hi!  I inherited a project to update a Help application that hasn't been touched in 7 years.  I'm not sure what version the old one was in, I think it might have been 5, but I'm using Robohelp HTML version 7.  It seemed to convert my files fine and I've made my changes.  These are the output options I have available:
    WebHelp
    WebHelp Pro
    FlashHelp
    FlashHelp Pro
    Microsoft HTML Help
    XML Output
    The developer who links to the Help application from his program is looking for three files ending in .cnt, .fts., and .hlp.  When I outputted mine to WebHelp (which is what I normally use), these three files were not created.  I researched the .cnt, .fts., and .hlp file types and discovered that they all seem to be opened primarily by Microsoft Help applications. This made me think that maybe I should be outputting the files as # 5, Microsoft HTML Help. Alas, none of the three required files were generated using this output method, either.  For good measure, I tried publishing the files as each of the 6 output options but no luck, the three required files were not generated using any of these methods.
    This is making me think that maybe in the last 7 years, Robohelp has made some changes and it's no longer possible to output .cnt, .fts., or .hlp files.  Is this true?  If so, I'll have to get the developer to change his code to point to some other file type, perhaps the Microsoft HTML Help .chm file.  If it's not true, can anyone tell me how to generate these three files?  Thanks!

    What your developers are using is a WinHelp file. This is produced from the RoboHelp for Word application rather than the RoboHelp HTML application. Don't worry though as you still have this as part of Robohelp 7. Just look inside your All Programs list for it. It uses Word as the editor and produces the files your require. Of course your developer could also change the application to start using Webhelp which would negate you doing anything ;-)

  • Crystal Report 11, List of Runtime DLLs, Runtime.hlp File

    I am using Crystal Report 11 with my Delphi 7 application.
    I need the list of runtime dlls which I will need to distribute with my application.
    The Help file which comes with the Delphi 7 VCL Component (UCRPE32.hlp) says :
    QUOTE
    check RUNTIME.HLP in the Program Files\Seagate Software\Crystal Reports\Developer Files\Help folder
    and make sure you have all the files.
    UNQUOTE
      I could not find the RUNTIME.HLP file in any folder/subfolders on the machine  where Crystal Report 11 has been installed.
       Can somebody tell me where I can find RUNTIME.HLP file or the list of runtime DLLs which is required to be distributed
    along with my application(which is written in Delphi 7).
        Thanks in advance

    Hello Ramesh,
    Business Objects does not support manual deployment of their runtime files.  This started with the release of CR XI (v11.0).  Please see [Business Objects Note 1218571|https://bcp.wdf.sap.corp/sap/sapnotes/display/0001218571] - How to distribute the Report Designer Component (RDC) in Crystal Reports XI for more information.
    You may also want to review the RDC deployment article - [Creating an RDC Distribution Package|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/901c0761-cf1d-2b10-dea4-8e83937a9337] - that can be found on the SAP web site as well.
    The RDC merge modules do not include the CRPE32.dll.  Since you're using the VCL you'll probably have to add that file manually to your deployment package.
    The merge module links in these articles have probably changed.  Go to the [Business Objects Support Software Download|https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/bobj_download/main.htm] page to find the RDC merge modules.
    Change the Selection Criteria to this:
    Software Product: Crystal Reports
    Product Version: XI, XI Release 1, or XI Release 2 (depending on your version of Crystal Reports)
    Software Type: Utility
    You should also be aware of the fact that the VCL is not being updated any longer.  I think the XI (v11.0) version is the last one that will be available.  Additionally, the Report Designer Component (RDC) has been retired with the release of CR 2008.  Going forward you'll have to migrate to .NET SDK or the Crystal Report Java SDK.
    I hope this helps,
    Sincerely,
    Dan Kelleher

  • URLClassLoader + dynamically loading signed jar files

    I have an applet that does not know all of the jar files it will need to load at startup.
    I would like to dynamically load these signed jar files using the URLClassLoader, however it does not recognize these jar files as being signed and I get java.security.AccessControlException: access denied errors.
    Any suggestions?
    Thanks!

    Try this classloader for loading the jars, it should to the trick:
    import java.net.URL;
    import java.net.URLClassLoader;
    import java.net.URLStreamHandlerFactory;
    import java.security.AllPermission;
    import java.security.CodeSource;
    import java.security.PermissionCollection;
    import java.security.Permissions;
    public class AllPermissionsClassLoader extends URLClassLoader {
        public AllPermissionsClassLoader (URL[] urls) {
            super(urls);
        public AllPermissionsClassLoader (URL[] urls, ClassLoader parent) {
            super(urls, parent);
            System.out.println(parent);
        public AllPermissionsClassLoader (URL[] urls, ClassLoader parent, URLStreamHandlerFactory factory) {
            super(urls, parent, factory);
        protected PermissionCollection getPermissions (CodeSource codesource) {
            Permissions permissions = new Permissions();
            permissions.add(new AllPermission());
            return permissions;
    }

  • What values to place in signer.properties file for Webutil configuration

    Hi. I'm not sure of what value to place in JDK_HOME in signer.properties for Webutil configuration. My current settings are:
    JDK_HOME=D:\ora9i\jdk
    JINIT_HOME=C:\Archivos de programa\Oracle\JInitiator 1.3.1.13
    #Certificate settings:
    # These are used to generate the initial signing certificate
    # Change them to suite your organisation
    DN_CN=Product Management
    DN_OU=Development Tools
    DN_O=Oracle
    DN_C=US
    JAR_KEY=webutil
    JAR_KEY_PASSWORD=webutil
    Is JDK_HOME the jdk for oracle or SDK for windows machine(how to find?)?. Also how do i repeat the process of makecert and signing of webutil.jar and jacob.jar?. If i try to repeat this process I get the following warnings or error?
    Makecert:
    keytool error: java.lang.Exception: Key pair not generated, alias <webutil> already exists
    Certificate created...

    JDK_HOME is just the location of a Java distribution with Keytool in it - have a look at the signer batch file and you'll see how each variable is used. Also if you run keytool from the command prompt it will show you the commands to delete and existing Key or list the keys that are currently stored.

  • How to automate digital signing PDF Files in batch

    I am trying to find a way to automate as much as possible the placing of a digital signature on a set of PDF documents.  We have Adobe Acrobat Pro 8.1 and the machine has MS Office 2003 with Vista Business.  Here's a scenario:  A set of documents exist in a TO-BE-SIGNED folder, each unsigned.  The user uses MS Access 2003 form with a button with VBA code to open and show the first document in the folder.  The AcroExch.App, AcroExch.AVDoc, and AcroApp.Show APIs are used to do this.  I found code on the internet to do that.  Rather than having my client now have to go through all the manual steps to place a digital signature on the document, I want to streamline it to a single click if possible.  Right now he has to click Advanced > Sign and Certify > Place Signature > then click and drag > then enter his password > then click sign > then save and close the doc.  Can all this be automated?  An added bonus would be automatically saving or moving the signed doc to a different folder when it is signed.
    I have created a stamp that allows me to add a stamp with just two clicks.  Can such be done to add a digital signature?  Is it possible to add a button to the toolbar to do this?  Can it be done in Access VBA using some Acrobat API calls?  Another feature I want to include is moving quickly from one document to the next in the TO-BE-SIGNED folder.  Like the arrow buttons take you from page to page, can a button be added to the Acrobat toolbar to take you from doc to doc in a particular folder?  Or can that be done using VBA and some Acrobat API calls?  To maintain the security of the password protection and yet cut down on clicks and keystrokes, I would like to input the password just once at the beginning of the session and have it remembered or applied to all the docs that get signed as long as that session is open.
    I've found some software that purports to do much of the above, but they are all very expensive and assume a big business with big bucks.  If anyone knows of inexpensive software that will REALLY do this, I'm open to that as well, though I'd like to control the process myself if possible.  I consider myself a beginner with Acrobat and using API calls and would appreciate any help anyone can give.  Is the above clear and even possible?
    PS:  I'm new to this site and using SDK.  I posted this under Security (thinking digital signatures) and was asked to post it here, which I'm glad to do.
    Thanks much!

    Our workflow is such that on infrequent occasions, we have a digitally signed PDF file and the doctor wants to append a scanned note to it.  In the past, we could do this, but not now.  In the past, when we added the scanned doc, we received a message saying that the doc is already signed and asking if we want to overrwrite the doc.  If we respond Yes, then Acrobat would allow it and the signature would indicate that the original part of the document was not modified, but that something had been changed--namely, a doc had been appended.  The signature indicated that something had changed since it was added, but it still allowed the append.  The signature would have an exclamation point in a yellow triangle indicating the doc had been updated since signed.  For our purposes, that was okay because we know what the change is based on the original doc and we know what is appended.  Now, however, we cannot append at all.  The only thing that is different that I know of is that the doc was signed with software that is not Adobe Acrobat, even though the other software uses an Adobe Acrobat self-created digital signature.
        I hope I've explained that clearly enough.
    Thanks for your help.

  • How to remove password-encryption in a signed PDF file?

    I can open a password-encryption and digitally signed PDF file using Acrobat X Standard but cannot remove the password protection.
    Can anyone help me remove the password encryption?  The Acrobat only allows to set passsord encryption before adding digital signature to a PDF file.  Can I sign a PDF file and then encrypt it with password?  Thanks.

    Removing the security, if it is possible, would destroy the signature.
    Encrypting a signed PDF would destroy the signature.
    This is because signatures validate the file exactly as it is, and changes to the file break the signature by design. Setting security is a change to the PDF (a big change).

  • How can i add update signed jar file

    I am developing an applet which requires signing to run in a browser.
    I am developing supporting classes. But these class files have to be added
    to the jar. Isnt it??
    But to test the applet i need to load it in the browser each time i modify the class files. So the jar file need to be updated every time. But an
    IOError
    is being displayed when i try to update the signed jar file.
    How can i update signed jar file?? Or is there any othe way to test the signed applet during development??

    How can i update signed jar file?You can't, the signature is there to make sure the content of the jare hasn't been messed
    with.
    Either recreate the jar and re sign it or set up a policy during testing.

  • Will RoboHelp 10 import .hlp files created from RoboHelp 7?

    I downloaded the trial version of RoboHelp 10 and tried to import old .hlp files that were created long ago with an earlier version of RoboHelp.  I keep getting an error  "The specified help file could not be opened.  Ensure that this help file is not running and try again".  Am I getting this error because I am running the trial version of RoboHelp 10 or are these old files not supported by RoboHelp 10?

    Welcome to our community.
    The error should not be an indication that you are using a trial. Have you confirmed that the HLP file isn't actually open on your PC?

  • Can I generate .hlp files

    We just upgraded to Frame 9 (from 7.1) and RoboHelp 8. Prior to the upgrade, I was using WebWorks to generate my .hlp files - is there a way to generate .hlp and .cnt files with RH8?
    Thanks in advance!

    Hi there
    Sounds like you are creating 32 bit WinHelp files. If you want to switch to 16 bit WinHelp files, the viewer is already present on Vista and Windows 7, so no download would be needed and WinHelp would still work.
    Whether WebWorks allows you to choose between 16 and 32 bit WinHelp files is another matter... Rick

  • Winhlp32 for old .hlp-files

    Hi,
    I can't see anymore the Content of old hlp-files on a 64-bit-Win10. will the old .hlp-Files be supported anymore? For Win8/8.1 there exist a msu. (Windows6.1-kb917607.msu / Windows8.1-KB917607-x64.msu)
    Thanks

    Hi karesol,
    Currently, there is no such application or update applied for Windows 10 Technical Preview. I notice some similar functions which have no appropriate update to support Windows 10 Technical Preview, but everything should be ongoing.

  • Generating hlp files in RoboHelp HTML

    Is it possible to generate .hlp files from RoboHelp HTML version 9? We're generating help files for an older program that only uses .hlp or .chm files. I've only been able to generate .hlp files from RoboHelp for Word, and I don't really want to use it any more. But I haven't been able to generate .hlp files from RoboHelp HTML.
    Thanks.

    Hello PP
    I'll be happy to hazard a guess as to why RoboHelp doesn't "do" WinHelp. It has to do with the history of RoboHelp. Way back around 1992 or so, RoboHelp existed largely as a plug-in to Microsoft Word that made it a lot easier to create WinHelp files. Basically it was a set of macros that formatted the arcane coding necessary inside Word documents that made things work for the WinHelp compiler.
    HTML emerged later on and the first version of RoboHelp HTML was born. This created an entirely new format and an entirely new application (RoboHelp HTML or RoboHTML) was born. HTML help was the new kid on the block. As such, I'm guessing the developers were sort of watching to see if or how much it would "catch on".
    So the application code bases were totally different. And remain so to this day. As Microsoft has taken measures to try and dissuade folks from using WinHelp, I'm sure RoboHelp for Word is likely on life support and probably has been for some time. RoboHelp for Word and RoboHelp HTML work in totally different ways. And given the fact Microsoft wants WinHelp gone, it simply doesn't make any sense to expend effort on making RoboHelp HTML capable of outputting WinHelp.
    Cheers... Rick

  • Reading .hlp files

    Hi all,
    I have a .hlp file (Windows help file) which I want to be able to read on my Mac. Is there a program to read it or to convert it to a Mac help file?
    Thanks,
    Ziv

    That is what I do.
    I just thought that for reading a help file I would not need to consume much of my system memory and cpu power.
    Thanks anyway,

  • Viewing HLP files

    Anytime I share my hlp file with anyone they receive the
    following errors
    Cannot find or load the file wh2robo.dll. This file should be
    copied to C:\Windows\System32 or a directory in your path
    what am I doing wrong?

    Hi jar92380
    Those that know me will probably gasp when they read this,
    because it's been so long since I've used RoboHelp for Word.
    However, try expanding your single source layouts, then right click
    the layout you are building. Click the Properties item on the
    context menu. Click the Next > button once. Look in the Compile
    Options area. My guess is that you have the option labeled
    "ActiveEdit (for Development)" enabled. Click to set it for
    "Release (for Shipping)" and recompile. Maybe this will correct it.
    Cheers... Rick
