Saving a file of the APEX help before the process of Header error

Hello

I am current trying to simply allow the user to download and save a text file after pressing a button on a page of the APEX. Links to a new page which does nothing except button perform a process before header containing the following pl/sql code:
begin

-- Set the MIME type
owa_util.mime_header( 'text/plain', FALSE );

-- Set the name of the file
htp.p('Content-Disposition: attachment; filename="alphafile.txt"');

-- Close the HTTP Header
owa_util.http_header_close;

htp.prn('Hello World');

htmldb_application.g_unrecoverable_error := true; 

end;
When I then press the button to access this page, I get a blank page which shows:

Content-type: text/plain; Charset = UTF-8 Content-Disposition: attachment; filename = "alphafile.txt" Hello World

Any help is greatly appreciated.

Kind regards

Alex

Hello

I think you should do application process state for example PRINT_FILE, and then the url button

f?p=&APP_ID.:&APP_PAGE_ID.:&SESSION.:PRINT_FILE

For this application process "on the load before the heading" need you from your code

Or try htp.init place start your code

Hope that helps

  • Problem with changes saved in files Excel download (APEX 3.2.1)


    Hello community,

    I have a Table and store Documents in there.

    I would give a link for users to open a file downloaded Excel, make changes, save them and finally to close the file.

    Unfortunately, the changes are not saved.

    I think it's a problem with the privileges. But those that need me?

    When I go on ' save under ' in a file Excel open, the owner is "Apache IO" and I don't have any directory on the server to save.

    I hope someone has a solution

    Thanks in advance

    Before you create a shared directory (this is not a DBA, but a sysadmin task incidentally) and a background process, you need to specify what and how you want to do something first. Maybe a shared directory is not possible (for example in the case of a Web application). Talk to your system administrator before you build anything.

    Even with a shared directory, you must do a lot more than just put a file there. If a user saves a "myfile.xlsx", but what to do with this file? Is he related to something, such as a purchase order, the invoice, the project...?

    Maybe you have seen the document management systems where you open a file in the application and save by clicking the Word or Excel records. But these are based on plugins, Office and other software installed locally on a PC.

  • CHM files in the process of disappearing/Reappearing

    I had a bit of a mess of naming with my CHM files. It turns out that the names I gave some of the files were too long and that it had underscores, which caused problems when I am committed projects to Subversion (the application of version management software we use). I tried to create new CHM files and removing the 'old' but the 'old' return. I tried to remove the nine and just rename the 'old', but they both return.

    I know that the information must be stored in a different type of files in the project I don't see where this trace down and how to fix it. I need to solve this problem before that I keep all my documents and time is short. Anyone have any ideas as to what I'm doing wrong and what I should do to fix this problem? Thank you.

    -Travel

    You say that your CHM file names are top revereting the old names after compiling? If so, which is easily fixed. Right-click on your layout of the only source of Microsoft HTML Help, and then select "Properties". In the first field, you can specify the file name (and path) of the output file.

  • CHM files in the process of disappearing/Reappearing, part II

    I had this problem before and thought, with the help of Colum, I had thought about it. Seems I was wrong. Here is the original for reference thread:

    http://www.Adobe.com/cfusion/webforums/Forum/MessageView.cfm?forumid=65 & catid = 449 & ThreadID = 1319556 & highlight_key = y

    A week or two ago, I needed to change the name of my CHM for my main project files and subprojects. I opened each project and on the tab project manager, expanded the unique Layouts of Source folder. I right click on the Microsoft HTML Help (main layout) file and choose Properties. In HTML help in the field Options to select output folder and the file name, I change the name of the file from OLD.chm to NEW.chm for each of my projects.

    Yesterday and today, I've been making changes to the content in my projects. On the table of contents of the main project, I deleted the links to the topics merged and re-created, pointing to the latest versions of new CHM files subprojects (after compiling the CHM files for each subproject).

    Then I compiled the CHM for the main project and checked the! SSL! folder. My new CHM files, but are not only * old * CHM files as well. I deleted the links of the master project TOC, recompiled (after manual removal of the CHM old files from the master!) SSL! folder and return the old CHMS.

    I know I must be missing something simple, but unfortunately, I can't understand what it is. Suggestion, if you please. Thank you.

    -Travel

    Did you do a search in the whole of the project to ensure that your old CHM file names are not referenced anywhere? They are in the baggage files? My guess is that you open your master project. High hydrostatic pressure in Notepad file, you will find that the former names of file in the [MERGE FILES] section at the bottom of the file. If definitlely you do not all other references to them you can delete them manually from the. HHP file and try to compile it again. Warnings usual to take backups, sacrificing goats, etc. should highlight when you edit one of the files in the project outside of HR.

    Hi MarcSatz,
     
    -Did you change on your computer before this problem?
     
    This problem occurs when one or more of the following conditions are met:
    • The registry values that are associated with the file name extension are corrupted or missing values.
    • The computer is infected with a virus.

    Here is an article that will guide you in the process of fixing the issue:

    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:

  • What is the relationship between the source code (LKS) file and the process file (L4P)?

    I know that Lookout produces a file of source code with an LKS extension when you save a file to process.  Can someone explain the relationship between the two files, especially while the (L4P) process is running?

    1. Is this just a backup file can be recompiled in a process file?
    2. A file corrupt LKS cause strange problems with operation process file?

    I currently have a very strange intermittent behavior with a process file run.  I first thought that the problem was associated with my Fieldpoint and/or their configuration modules.  Since then, I found that my process file has a file corrupt LKS.  I repaired and recompiled my LKS file to a new file to process.  I still don't know if I have solved the problem or not.  So, the problem is intermittent, I did that about 20-30 SECONDS to resolve the problems there before he goes.  Then he can not show up again for another 2-3 days.

    The .lks file is just the source code of your process. It can be opened by a different version of lookout, but does not have the .l4p file.

    The .lks file is not be used while a process is running. Lookout does not read the file more after his execution. So it should not affect the running process.

    What kind of problem, is it?

  • account user corrupted and files in the process of disappearance

    I use my second account mainly and my documents such as letters and addresses in soft micro works are endangered. Records are missing too. I do a search on the hard disk and there is no information. In microsoft works history information is there, but when you click on a file, it indicates that the file has been deleted. I use virus protection and the analyses. When I load a program from a CD-ROM program works fine on the adminstrative account but errors appear on the secondary user account. I tried to make a new user profile and I have the same problem. Could someone please recommend a solution to this problem. Do I have to reformat the hard drive? Any help will be appreciated.

    It is possible that your user profile is damaged.  When this happens, Windows creates a new profile for you and when you connect, it looks like an office of a new user fees.  The files stored in the user (under 'My Documents') profile will be absent as well.  If you start the Explorer and look in the directory "C:\Documents and Settings", you will probably see a folder with your problem with that user name and contains your old files (let's call it 'user') and maybe another folder with the same user, followed by a point and maybe the computer name (such as "user.computer") that represents the profile of recovery system.  If that's what you see, the following article should help you recover:

  • Getting the name of file in the process of BSE

    Hi all

    I have a simple requirement to transfer files to FTP location to the location i.e. SOA server read and write to the directory specified in the SOA. To do this, we use the Oracle ESB. (Suite 10.1.3.4 SOA).

    This works perfectly well.

    Problem:
    There is an overrun of the writing of the file with the same name as the file name of reading. I know that this can be achieved in BPEL using the header variable.

  • failure of pre-flight print saved PDF files through the "save under" function because of the current JavaScripts

    How can I disable using JavaScript in a PDF file that is saved with "Save as" option? PDF files print via postscript and distill are without JavaScript. PDF files that contain any JavaScripts fail the printing process before the flight and so we need to know how to disable all the JavaScripts in a PDF file even if Save as function is used to generate a PDF file.

    Thank you

    Peter

    Peter,

    I looked a little more on it, and regardless if you're reviewing post-processing routines or not, it seems that FM now always writes a javascript model when you use the SaveAsPDF routines. The script is actually empty, that is, it identifies the source as coming from FM, and here is the script embedded in the PDF document [he hasn't]:

    //

    FrameMaker

    //

    / * belongs to: Document-level: FrameMaker * /.

    //

    //

    It seems that your options are limited here. You cannot use the SaveAsPDF road and get rid of the script to the end of the FM of things. So you can use AcrobatPro to sanitize the document, create a script that will remove the javascript or talk to your printing provided by supplier to see if they will let the script above spend their pre-flight.

    Alternatively, use the print function to create your postscript and then distilling to create the final print-ready PDF. If you need to create a CMYK & Spot ready color output using the way of printing, then you will need to use GrafikHuset (today a freebie) PubliPDF in postscript output FM CMYK + Spot PDFs. download convert RGB:http://design.grafikhuset.dk/index.php/kontakt/downloads/grafikhuset-publi-pdf and more details available at the: http://www.grafikhuset.net/PubliPDF/

    many files in process

    My laptop is pretty close to yours, it's a Toshiba Satellite L755, 4 GB RAM with Windows 7 64 bit.  It is not the number of jobs that it's the applications that are load at boot time.  Include Office, Quicken, MS Works, etc.  What you can do without having to pay for it is to run MSCONFIG and eliminate this problem.  Here's how.  Hold down the Windows key and press on R.  Then type in msconfig and click OK.  Click the STARTUP tab.  From there, you can uncheck everything except your antivirus software.  Which will release little RAM and speed up your computer IF you have the problem.

    Good luck.

  • Return of the mistake of MUSE: why do we not have several files with the same name?

    Well - I thought I had all this worked and fixed, but I met the download error 'Why do we have several files with the same name' once again.  (I downloaded all the files several times today in order to 1) works the way it worked the last time and 2) get an OAM file that is not loading for some reason any load again and the download takes about an hour to transfer all the files manually.

    To recap:

    (1) an option "Upload only modified files" returns the 'Muse has encountered an error and closes.  Why do we have several files with the same name? "error just as before.

    (2) a full download will work but takes forever and is NOT a substitution for work changed files option.

    Please advise with possible solutions!

    Is it possible to have two .oam different files in different folders on your computer where the .oam files have the same name? I'm theorizing that there may be a bug in the treatment to ensure the folder created for a .oam placed on the server receives a unique name, particularly in the case of a partial update of the site on the server.

    Please send us the .muse file and all the files in .oam related to [email protected] along with a link to this topic for the context so we can attempt to reproduce this error and isolate the root cause. If files are larger than 20 MB, you'll need to use a service such as Adobe send & Track, Dropbox, creative cloud, WeTransfer, etc. file sharing. Thank you.
