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 The only protected PDF is an unpublished one.

I would like to ask the following if possible. We have a client that wants a separate pdf document, embedded in a main pdf document and opens when you click it. Like the function in MS Word where you can attach another Word document inside a Word document (Word-ception, lol) and you can still open it.
I've tried it in Acrobat Pro with the Attachment and Link tools. Another option was to put the link document in an ftp server for accessibility. but our client really wants this functionality. Is this possible in Indesign?
Thank you!
Using Word as your example vehicle there are several ways to link 2 documents.
One is an appendix to the other, in PDF terms is a merge or binding but its one flowing document with separate sequential sections/chapters.
Another way is to link to an external file, in PDF terms a hyperlink to a relative second file, which can be locally folder relative or a web absolute reference. You have tried that.
In Word we can add objects internally with icons, in PDF that can be an annotation comment attachment to save externally and action accordingly. You also seem to discount that approach.
Finally PDF offers an Adobe Specific Structure where multiple PDFs attachments can be imbedded in an overall PDF wrapper. These are called Portfolios and not! to be confused with their portfolio service
They are unpopular since in a browser without Adobe Reader they should only offer the cover page.
Whilst in securer offline readers the files may well be shown as attachments that you need to save or independently open to view them.
Only some non Acrobat viewers may view them as a collection. And in the past that required runing insecure SWFlash, But I understand that has changed ?
Here is how the 3 internal PDF files seen above were shown in older Acrobat 9.
Possibly the best experience is using Foxit Reader
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
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'm creating PDFs using Texmaker. I would like to create some of the PDF files so that when I give the PDF to others, they are not able to print the file or to copy the text. I know I can do this with some PDF creator applications, but can I do that from some command like program I have with Latex, MikTex and TexMaker?
It wouldn't be effective anyway. There are bits in the pdf format that purport to forbid the user from doing this, but they are really just suggestions that the reader application may or may not act on. There is nothing to stop a user from removing the code that inspects the bits from a free/libre PDF reader, or just to run a tool over the file to remove the restrictions.
I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform).
Where it gets tricky is I would like to allow the user to modify the contents of that form, and then somehow have those modified contents accessible to me. I didnt build the source PDF so I dont know how to allow the user to "save" the new contents so they can be read.
Any ideas on where I might start on this one?
You can also use the cfpdfform tag to read/write data to a PDF file which has a form. The important thing is that the PDF document already have the form fields available, or that you add them.
I just recently completed a task where I had to have a user fill out a normal web form, and then create a filled version of an existing PDF document. It worked like a breeze!
I think that depending on what you are trying to accomplish, having the user fill out the data in a web form is less confusing than serving up a PDF and expecting them to save that to update a file on a remote server. Just my opinion, though.

It's possible for users to complete most PDF forms in Adobe Reader, but when user's try to save the changes they get a popup prompting them that the PDF cannot be saved and would need to upgrade to Adobe Acrobat to have this functionality.
Since Acrobat 7 (or possibly) 8 it's possible to create a form so that it can be completed and saved in reader. In Acrobat open your PDF, and select Advanced -> Enable usage right in reader from the menu. This will prompt you to save the form and then anyone using Adobe reader can complete it.
Once that's done you can open the form in ColdFusion, populate some of the fields and serve it up to the user. Once they fill it in, save it and get it back in ColdFusion you can read the contents using the PDF related tags.
Please note: It's currently not possible to set the "enable usage rights in reader" flag from ColdFusion, you need a copy of Adobe Acrobat or access to Adobe LifeCycle server to do this.
