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.

Where exactly are the (product) image files stored? I can't find the images in my Shopware 6 installation folders. If it is in the database, explain how it is done and which table because I have looked at the media table and can't seem to decode where the image file is.
As #zabus wrote, this is dependent on the CDN strategy.
Those strategies are implemented in https://github.com/shopware/platform/tree/trunk/src/Core/Content/Media/Pathname/PathnameStrategy, in case you want to know in detail how a path is generated, which happens on-the-fly.
There is a WIP pull request to store the final path in the database.
Public files are saved in public/media, while private files are in files/media.
the env variable SHOPWARE_CDN_STRATEGY_DEFAULT defines how the files are saved.
For example:
SHOPWARE_CDN_STRATEGY_DEFAULT=id
I am not sure if i am going to be able to describe this right but ill give it a go.
We are working on implementing Azure search. At the core level we have searchable PDF documents that we want the text of them added to the index so all of them are searchable.
The initial thought was to just submit that document to the index via the add document rest api. The thinking was that this would be the most simple and quickest path
to getting the text of that document into the index. We also considered using and indexer and just having all the Searchable PDF docs in a blob store and have the indexer
crawl those every 10-15 mins.
We also looked into (based on a recommendation) submitting a standalone JSON file with the text from the PDF in it. Submitting that to the index either via the same add document API or
placing that file in a blob store. Within the JSON document we would need to have document identifiers that provide the index with the location of the PDF so that when that text is found
via search, we can make that clickable and as a result open the PDF.
It seems to me that pushing in the json file with the document add api. Indexing that and when it is part of a search we can use the doc id to link back to it and open it.
For those of you that have used Azure search. How did you implement?
If you're totally sure that only pdf will live on this particular index, then the first approach is faster to implement, since the native indexer can be used for extract the content of the pdf document as well to push it to the index.
Both approaches will work, but for the second one, you would need to extract the pdf yourself using an external tool.
Would it be possible to create and populate tables within ckeditor from uploaded files?
A user would choose a file from their machine in any format such as word, excel etc and it could display a formatted table in the editor....
It is pretty clear that one can create a table in CKEditor. Also, it is possible to add a table automatically. Now, if you want to automatically add a table based upon the content of an uploaded file, then:
create a form where the file can be uploaded
implement the feature with which one can upload the file
make sure you know where your files are, either using a database or a deterministic algorithm
implement a server-side functionality which prepares the content (table) data
use the prepared data as input at client-side
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.
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.
