Every time I reload my webpage new files are added to the c:\windows\temp\notes...\xsppers folder on the server. and these files are never deleted, I have to manually delete them, and it can be several GB of data to delete every month
I have a simple xpage with a repeat control that display data from several documents using a computed Field mapped to a rich text field.
the richtext fields contain a lot of inline images that has been added using the notes client.
Now, every time I reload my webpage these images are now detached to the xspper folder and is causing my harddrive to run out of disc space all the time.
What is the reason for this behaviour and how can I avoid it from happening?
In the image below you see all the gifs that has been created with a new uinque name, each time I reload my webpage a new set up images are added to the folder.
I am using Domino 9
As Egor Margineanu wrote, this can happen if your images are not stored as MIME images in your Rich Text item.
This forces the domino server to detach the attachment(s) over and over again to disc, because it is required to generate a GIF form the inline image. If you change the MIME type of your rich text item in your form and save the document(s) again, the images are stored in the "correct" format, and the domino server is able to identify that the images are already on the HDD.
As far I can see the temorarly detached attachments are not wiped when the session ends. This seems to happen if the application ends.
Not a complete answer but some clarification from the XPages Portable Command Guide, page 36:
The files remain in the temporary persistence location until the user
session expires. The file is not removed after the document is saved,
although it is no longer referenced by URLs.
It may be useful to change this
setting to point to a different location if the folder is taking up
too much space on the main server drive and another drive has more
available space. This option is server-wide, so it should be set in
the server xsp.properties file. Values set in a particular
application’s xsp.properties file are ignored.
Based on your question, Thomas, it seems that this is not what you are experiencing.

We are using Kentico 10
Question 1
We are using DirectUploadControl to upload image in a page form.
We have column PDFImage in the page type. I can see the value of this field to be a GUID.
Where the image is stored on disk when uploaded by this control? Which table is updated with file name?
I tried the page type table, cms document and media file but couldn't find.
Question 2
We need to process the image when uploaded. Is there an event? Right now we are doing this in DocumentEvents.SaveVersion.After
This depends on how the system is set to store files. So, it can be in the DB or on disk or both. When on disk, it depends what folder is set to store the attachments.
In the document events there is the SaveAttachment event - so maybe you can try using that one. Or, it might be better to create a custom uploader form control - depending on your needs.
The Problem
I recieved a pdf file at work which I then printed. In the pdf file there were several optional fields where one could enter information such as "place of birth" etc. If I open the pdf file on my computer, I can see a set of input information A (a travel request with dates from this year 2017).
If I print the pdf on the local printer, the printed document contains a set of information B which for example contained travel request dates from 2015.
This information was not visible when opening the file on my computer.
I have been able to reproduce the error multiple times.
Why is this a problem?
It seems that previous entries into the pdf were yet somehow stored in the pdf contrary to what was visible when opening the pdf. When printing, the printer seems to access only the oldest entries and prints those.
This is a potential breach regarding data privacy and security since the pdf file seems to save all previous entries without anyone knowing.
Especially at work, some of these pdfs contains bank account information and other identity related information.
The Question
Did anyone experience a simliar issue or knows how to delete the invisible old information yet stored in the pdf?
UPDATE1: I could not reproduce the error on other printers. It seems this error is caused by the specific printer. Yet the information must be present in the PDF file, which is the specific cause of my question.
UPDATE2: Using the information from the accepted answer, I used the program "PDF CHAIN" and selected the option "drop XFA from document". I then saved the manipulated document again and printed it on the same printer.
Finally, the correct information was printed.
At a guess (and that's all it is without being able to see the original file) the PDF contains optional content or annotations which contain different field data for Print and Screen.
If you open the file using a PDF consumer (eg Acrobat) then what you see is the 'screen' result. Depending on the consumer you are using it may then either send the screen data to the printer, or substitute with the 'Print' data.
The printer you note as being a problem is capable of direct PDF printing, you haven't stated if that's how you are printing the PDF file, or whether you are using an application, nor whether the other printers are PDF capable or not.
My guess is that there is a different decision being made somewhere in the 2 print paths as to which is the 'correct' information to print.
Note that this does not mean that the PDF 'seems to save all previous entries without anyone knowing'; that's not really possible with a PDF file.
A malicious PDF processing application could do so, by adding comments to the PDF file, but only that application would be able to retrieve it.
But it is possible to have multiple entries of different types for different purposes, and if they aren't the same (because of the tool used to edit the file) then you can get strange results like this.
Note that if this is a problem for you then you probably shouldn't be using PDF, but you can mitigate the issue by digitally signing your documents. Signed PDF files include means (secure cryptographic hash) for verifying that the document has not been tampered with . Of course, you can't then edit the PDF file without re-signing it.
Oh, one other possibility would be that the PDF was actually an XFA form; its possible to have part of the document be a valid PDF which prints 'something' when a PDF consumer can't handle an XFA form, but that need bear no relation to what you see when you use an XFA processor.
My money's on optional content, AcroForm fields, or annotations where the Print data is different from the Screen data though.
I have a SafeCracker File for as a fieldtype for my channel entries. Everything works fine and i'm able to upload images along with the entry. In EE control panel, if i edit the entry and delete the image or even if i delete the whole entry, the images associated with this entry is are not deleted from the server. Why is this happening. is this a known issue.
This isn't a bug; it's how ExpressionEngine handles file assets. When you delete an image from an entry, EE deletes the relationship between the image and the entry. The image will continue to exist on the server until you delete the image itself. To do this, navigate to EE's file manager and delete the image there.
The reason EE behaves this way is because it allows you to easily link to an image or file from multiple entries in the system. If you had multiple entries linking to an image and were able to delete it from one of those entries, you would break the relationship to it from all of the other pages that referenced it.
I want to develop a news App such as Engadge etc. The news had loaded from the server, and now I'll save the news included body text and pictures into database(Core Data). Can UIWebView read the datas from Core Data directly, and shows in UIWebview?
Thanks.
Yes and no. You can store the HTML content in the database (CoreData), to show an article you use: loadHTMLString:baseURL: of UIWebView to show the textual content. The images however is probably best stored outside the database as file because you will have to point the image references in your HTML to an actual file.
You could store the images as BLOBs but then you need to pull those blobs and write as files later for UIWebView to be able to pick them up.
I think the easiest way is to store images as files and but place references to them inside CoreData. That way you can also delete them accordingly later on.
If by directly, you mean without any glue code, then no, not on iOS as of present.
You could however use Core data to store text and image objects as desired. It might not be the best idea to use a UIWebView, but to answer your question, it's definitely possible, and in fact quite easy to do so.
This is primarily a question of possibilities more than instructions. I'm a programming consultant working on a WSS project site system for my client. We have a document library in which files are uploaded to go through a complex approval process. With multiple stages in this process, we have an extra field which dictates what the current status of the document is.
Now, my client has become enamored with the idea of PDF watermarking. He wants the document (which is already a PDF) to be affixed with a watermark corresponding to the current status, such that with each stage of the approval process the watermark will change.
One method, the traditional method for PDF watermarking, of accomplishing this is to have one "clean" copy of the document somewhere hidden on the site, and create a new PDF from it that has the watermark at each stage of the approval process. Since the filename will never change, this new PDF can be uploaded continually to a public library, always overwriting the old version and simulating a "dynamically changing watermark". However, in the various stages there will also be people uploading clean copies with corrections and suggestions, nevermind the complex nature of juggling around two libraries and the fact we double the number of files stored. My client and I agree that this is not a practical path to choose.
What we would like to do is be able to "modify" the watermark in a PDF, so that we only have to keep one copy of the file. Unfortunately, from what I've seen, in most cases when you make something like a watermark, which in its nature is supposed to be "unmodifyable", you won't be able to edit it later. So, is it possible to have a part of a PDF which cannot be changed by anyone who downloads the file, but can be changed as part of a workflow or other object model process?
PDF Watermarking in SharePoint is a common request. I have written extensively on this topic. See:
Adding a dynamic watermark to a PDF file from a SharePoint Workflow
Adding a (static) watermark to a PDF file from a SharePoint Workflow
Use SharePoint Workflows to inject JavaScript into PDFs and print the ‘open date’
You could use Event Handlers such that code was run every time a document was checked in. In that code you could perform the fixup/check that made the watermark be what you wanted it to be. This assumes you can write code that manipulates a PDF's internal structure such that it has the watermark that you desire.
It sounds to me like you want to allow people to modify the PDF they download, but not modify its watermark. This is probably going to be nigh on impossible if the watermark is embedded in the PDF (afaict) but what if the watermark image is external to the PDF; is it possible to embed a watermark in a PDF that is sourced via HTTP? Then you could embed:
<watermark image="http://sharepoint/site/_vti_bin/docstatus.asmx?id=5">
Of course, I have no idea about PDFs, so this might not be possible but you get the concept.

It is possible to do so if you use third party tool. Then you can put dynamically binded value from your SharePoint metadata, conditions, rules etc: http://www.pdfsharepoint.com
