Call help file in a form

Hi!
I have a form where i have a button to call a help file. I've create my help file with RoboHelp and then generate it to Oracle Help. But now what i want to know is how can i call my help file? What's the function to call the file?
Thank and sorry for my bad english :-)

This is the easiest (IMHO) way to create help for your forms application:
1. Deploy your generated help in OC4J container (OC4J_Help using application-root /ohw/ for example
2. Write code like this in your KEY-HELP trigger
url := '/ohw/help/?topic='||:SYSTEM.TRIGGER_FORM;
WEB.SHOW_DOCUMENT(url, target);
you can put this code into .pll of course

  • How to call pdf files from oracle forms

    I have a pdf file in the server , I need to call this and open when a button is pressed in the oracle forms.
    Please let me know how to do this.
    Thanks,

    Frank,
    I have oracle applications and I want to open a pdf file located in the server from a button in oracle applications.
    Previn,
    you don't mention the Forms release you are running.
    If you are running Forms on the web, you can use
    web.show_document() to load files from the Web if
    they are accessible via HTTP.

  • Attaching help file to forms 6i

    hi, how can we attach help file to d2k forms. can we pop a particular content int hat file when the user presses F1 key.
    thankz in advance
    sanki

    There are different ways:
    1) To use .hlp files (Win help).
    host('c:\winnt\help\Regedit.hlp',no_screen);
    2). To use .chm (robo help).
    host('hh c:\winnt\help\iexplore.chm');
    3). To use .HLP with win_api_shell.winhelp.
    win_api_shell.winhelp('c:\winnt\system32\Odbcjet.hlp', '', win_api.help_finder);
    In order to use win_api_shell.winhelp procedure, you need to attach the D2KWUTIL.PLL to your form.

  • How to open .cmdrw file from Oracle Forms 10g

    Hi,
    We need to call *.cmdrw* file from Oracle forms 10g. Is there any way to call *.cmdrw* file from Oracle forms 10g?
    Thanks for the help.
    Viishnu Nekkanti

    In case you want to open a .cmdrw with its associated application you can use the following procedure:
    webutil_host.NonBlocking( 'rundll32 url.dll,FileProtocolHandler ' || client_filename );This works for every file where a program has been associated to its file extension. (Adobe Reader for *.pdf, Microsoft Word for *.doc, Microsoft Excel for *.xls and so on)

  • Html help file not initialized.

    I have generated a help-file for a form and the file is fine.
    The Content_id is set, and I have generated the form again.
    I4ve set the help preference to HTML, and the code for the key help is added as follows:
    BEGIN
         CGHP$CALL_HTML_HELP(
              'CG_FORM_HELP',
              'IZI.htm',
              'c:\appl\fmb\',
              '_blank',
              'IZI3020F',
              :SYSTEM.CURSOR_BLOCK,
              :SYSTEM.CURSOR_ITEM);
         message('passes here!');pause;
    EXCEPTION
         WHEN OTHERS THEN
              CGTE$OTHER_EXCEPTIONS;
         message('error!');pause;
    END;
    It doesn4t go to the exeption and seems to pass the message after the call to CALL_HTML_HELP. I have checked that the QMSLIB65 is attached before the OFGHLP lib and that is so!
    I don4t have a clue as to what I4m doing wrong. Are there other preferences to be set, or are you not able to call the HTML from the network drive. Or should I set a different path or no path at all??
    Thanks fo anyone who takes the time to try and help me!
    Martijn!

    Martijn,
    Try setting the help preference to MS help instead of HTML help. I know this is counter-intuitive. :-)
    Headstart forms do not use the native HTML help generated by designer, because this help relies on querying the help information from a database table. Rather, we override the CGHP$CALL_MS_HELP procedure to display the html help document.
    You can look at the headstart demo application to see how this is done.

    Lauri

  • Creating Dev 6.0 Help Files

    Anyone know of a quick and easy way to generate help files for a Forms application. The Oracle doc suggested a 3rd Party solution. Is there anything like the Wizard or Calendar built-ins, and while I think of it, free would be nice too???

    John Davies - you're the man!
    On xp Windows PM 7 I have produced a 60-page chapter for an illustrated book. The diagrams comprise a paper filled line rectangle, with a black filled rectangle behind it. The black rectangle is nudged to the right and to the bottom, to create a black drop shadow. I placed the eps diagram over it, to the front layer.
    I need to produce pdf file. So, I generated a postscript file; then used Adobe 9 distiller to produce a pdf.
    Everything is perfect up to page 28. After this page, all of the diagrams show the black rectangle through the paper-filled ones.
    I have double-checked PageMaker diagrams, and even tried to generate just one of the rogue pages but it still shows the black rectangle in Adobe Reader. All text and fonts are perfect.
    Please, any help appreciated! Thanks

  • How to call .chm Help File

    Can anyone provede me a quick suggestion.
    Thanks in Advance

    DIAdem doesn't have a method to open .chm files because these files are Microsoft help files, rather than DIAdem specific help files. However, there is a KnowledgeBase on Microsoft's web page that may be of help. You can find this document at http://support.microsoft.com/?kbid=209843. I found this by doing a web search for "Programmatically open .chm". I hope this helps you.
