Am currently working on a web application which receives the encoded text from the web service and am decoding & saving as a PDF file. Once the user clicks for the details then I am supposed to display the PDF file in the web browser.
What is the best practice to display the PDF file in the browser? Am using VB.Net 2003
All you need to do is set the link to point to your pdf file. And if the user has any PDF reader installed, it will be opened using that reader.
The name you Want to Show as Link
EDIT:
The other way, if you dont want to display as link and directly open the file, is to set the correct MIME type in the headers, so that the browsers can detect it as PDF file instead of HTML file.
Response.AddHeader("content-disposition","inline;filename=YourPdfFileName.pdf")
Response.End

With the latest version of Firefox (107) it is now possible to edit and sign PDF documents within the browser preview window.
But how can I upload an updated version of such a PDF file back into my Web Application?
Is there any kind of JavaScript API I can use?
There is much overlap between PDF web editing browsers and Browser editing PDFs
the data is pulled down locally and the binary application edits the data however for a PDF, that then requires a local save as a new combined PDF. here we can see a visual reminder.
In Firefox or Chrome there are slight differences but the core need is to resave the PDF as a clients local file.
Chrome has inking
And Firefox uses a slightly different overlay but again the conjoined local data must be first saved as a new PDF.
either by print
or the top right Save (again) AS
Thus to achieve your goal you need to ask the annotator user to upload their masterpiece. However you cannot easily do that in the sandboxed page (with work frame) it needs to be after a user signal such as press button here to upload where-ever IF you were able or bothered to save as a new pdf.
The below is the line of code I'm using it currently which converts ppt to pdf, however I want to protect pdf , Is there any possibility
PowerPointapp.ActivePresentation.SaveAs path & pdffileNm & ".pdf", 32
This is not possible with the default vba functions available!
See this, not tested by me, example of using an external library to save pdf with password in the past.
Protecting a PDF is not permanent, once the file is opened (using the users decryption key provided by handing over the password), the contents are available to the new owner to add comment or fill forms or otherwise modify by print or text edit or remove watermarks.
Adobe reader will use different parts of those keys to reduce user writes, but no other editor has to.
Browsers need to edit PDF in exactly the same way so my Firefox pdf reader allows me to correct / change web page content or the embedded pdf contents, exactly the same as any other browser or pdf viewer or editor can. The only protected PDF is an unpublished one.
Through a web service I get a PDF response. When I hit the endpoint through my browser the file is downloaded and saved as I would expect.
The problem: when I open the downloaded PDF the content appears to be encoded. If I paste the PDF content into something like MS Word or even Chrome, it becomes readable english.
I have opened the PDF using my code editor to inspect the metadata, but I don't know what exactly I'm looking for.
How can I get the content to display as readable english when the PDF is opened?
Any help would be much, much appreciated!
Here is a link to the PDF in question: testPDF
I was wondering if it is possible to open a pdf file (located on a web server) in a web browser, edit it and then save it with the changes. Basically what I need is to open, edit and save a certificate protected pdf file in my web browser, without ever having to download a copy to my desktop. The pdf file contains textfields that needs to be filled out with text before saving the changes.
I know that it is possible to view pdf files in a browser, but im unsure if it is possible to edit it when it is protected by a certificate.
What you are asking can be performed in the following methods: First which is the simplest way is to use Adobe Forms server. If you would like to use your own PDF, you will need to extend reader extensions display the form in a frame and perform cross scripting to tell the form to post itself to the server. Note: read Adobe Reader Extension licensing extending reader extension has restriction on usage.
Obviously you can enable reader extension allow user to download edit and upload the file to your server.
Certified forms means you cannot change the form structure but you can fill the form and save it (if it is reader extension enabled)
I have looked for weeks and I keep hitting dead ends. I know you can create a text or image link and tell it to "print page" in a browser. But so far, I can't get it to print a document, specifically a pdf. I would like the print dialog to show after the link is clicked and yes, the pdf linked to has been printed.
Why does this seem to be such an impossible feat? I have seen it work in a Flash movie, but since I cannot access the native file I cannot see how it was done.
Any advice?
Thanks.
Many of today's printers support direct PDF printing. Lexmark, HP, Xerox to name a few all have this on most of the 'business' printers. On these devices simply sending the PDF file directly to the device over LPR, port 9100, or some other mechanism will result in a printed document. Some devices even support URLs. I do know that Lexmark had some devices that a URL could be sent to the printer as as long as it had access to the URL it would pull the document and print. In this case it supported basic HTML, JPEG, TIF, and PDF.
Hope this helps.
A PDF must be rendered as an image before it can be printed. Usually when you're printing a PDF file on your desktop you could simply right-click on the file and select Print and if you have Adobe Reader or an alternative application set as your default PDF viewer, then the PDF that you have selected will be opened automatically -- at this stage the PDF is rendered as an image -- and then the printing process will begin.
But if there is no access to a PDF viewer that can render the PDF and then print it, then you won't be able to print the PDF. Usually if you have Adobe Reader, Foxit Reader, etc, installed then when you click on a URL to a PDF then the PDF will open within the PDF viewer within the browser and you will be able to print it.
Alternatively, you could find a PDF SDK that silently renders a PDF as an image and then sends that to the printer, without the need to have a PDF viewer installed on your machine.
