I am using sensenet and react based client for front end. while copying a file from one document library to another I am getting the following error:
"Cannot copy a list item into an another list".
Can anybody tell me how i can solve this?
This behavior is currently by design. The reason is that content lists (doc lib, task list, etc.) may contain local list fields. If you had a document in a list with a custom metadata field filled with a value, you would loose that value if you copied the document to another list.
Workaround 1
If you do not need the list/library functionality (custom metadata fields, etc.) than store documents in a simple folder instead of a list. This will let you copy those documents wherever you want - even into a list. In this case you have to take care of setting the allowed child types (most likely File) somewhere on the parent chain (e.g. on the workspace), because you cannot set this value on simple folders.
Workaround 2
Copy files using a temp folder. It is allowed to copy a file from a list to a temp folder, and also copy a file from a folder into a list. I know, this is not very convenient and we are considering changing this behavior to make it more permissive, but this is how currently works.

I'm working on enhancing metadata in our SharePoint online (O365) environment. Since a portion of my user base is used to foldering (explorer style), I've started using default column values to automatically set values on any files added to that specific folder (we have content organized categorically by folder currently). An example is our HR documents library - we have separate folders for recruiting, payroll, personnel files, etc. that automatically categorize files added to that folder with the same categories (recruiting, payroll, personnel, etc.). This supports both "search" and "click" users and makes adoption WAY easier while getting important metadata.
I want to implement this in a larger, more dynamic fashion, so manually setting default column values on each folder is not going to be scalable.
How can I reference the top level folder within the library (or even the current folder) for each newly added file and populate the "category" field for that new file with that folder name? I can do some very basic C# or Java code copy/paste, but bonus points for non-coding solutions =)
This problem can be solved through no coding.You can use the workflow to implement this by SharePoint Designer.
Create different view for different function team, and then use the view filter to show the document.
If you upload a file, use the workflow to set the metadata of the file. There are some known limitations: if you upload multiple files at the same time, the metadata for the file maybe does not work well; or if you upload a folder, the meta will not work for it and the file in the folder may not be set to right metadata.
I was actually able to use MS Flow to accomplish this in a pretty simple and straightforward fashion without managing custom views per team. The concept at a high level was:
(Trigger) When a new document is created in a folder in the library
Get the link of the parent folder of the newly added document
Create a variable (or just code it out in the Flow step) to parse out the name of the parent folder from the parent folder link (should be all text to the right of the last "/")
Set the category field as the variable
I'm sure that you could do the same right in a SharePoint designer workflow, but I prefer flow due to the visual aspect of it and being far easier to troubleshoot.
I am when trying to use java / c# or any other programming language to modify .pbix file which generated from Microsoft Power BI. Is there any dll provided by POWER BI or how can i read the content through program. I just want to get and update the datasource directory. Please help.
Thanks.
I don't think it's possible, and even if it is, the solution is likely inelegant.
Even if you managed to do this, you would need to open your PBIX file in the PBI Desktop to refresh your data.
Are you doing this because you have many queries and it's inconvenient to change data source string (folder name) of all of them? There is a way to keep your connection string in a single variable as described here.
I don't know your exact setup, but looking at your question, lets say you have sets of files in different folders and you want to change the folder in one step.
To use the approach from the link above but with file input, you need to do the following:
If it's a new report, import your files as usual
Create new query: "New Source"->"Blank Query"
You will see "Query1" and an empty text box, enter the folder name, for example "C:\". Rename this query to "Folder".
Go to your imported file in the query editor, "test1" in my example. In query settings on the right, select source.
Change the filename by substituting the folder with your "Folder" query, for example:
...File.Contents("C:\test1.csv"),...
...File.Contents(Folder & "test1.csv"),...
Repeat for all imported files, then "Close & Apply".
Now whenever you need to change the folder with your files, edit your "Folder" value and "Refresh".
I've become stuck at this hurdle. I'm trying to create a database that clients fill in, however the client can set different database paths to view different information in the program. I want to create template databases so should they wish to create a new database it will work with the SQL queries the program uses.
I'm trying to save the templates in to the program so that when a button is clicked, the template file is "downloaded" (copied) to the clients desktop.
Is this even possible?
Thanks
You can open the Resources page of the project properties and add any existing file, including a SQL Server MDF data file. At run time, you can get the data of the file from the appropriate property of My.Resources. The type of the data depends on the type of the file. I'd expect that an MDF file would come back as a Byte array, which you can then write to a file or whatever.
That said, you don't want to make your EXE too big by embedding several sizeable data files in it. You might be better off just using loose files in a subfolder or, if you're determined to use resources, create a satellite assembly, i.e. a DLL that contains just resources.
I'm currently working out the best structure for a document I'm trying to create. The document is basically a core data document that uses sqlite as its store, but uses the Apple provided NSPersistentDocument+FileWrapperSupport to enable file wrapper support.
The document makes heavy use of media, such as images, videos, audio files, etc. with potentially 1000s of files. So what I'm trying to do is create a structure similar to the following:
/myfile.ext/
/myfile.ext/store.sqlite
/myfile.ext/content/
/myfile.ext/content/images/*
/myfile.ext/content/videos/*
/myfile.ext/content/audio/*
Now, first of all I went down the route of creating a temporary directory and placing all of my media in there. Basically creating the paths and file names '/content/images/image1.jpg' as I wanted them to appear in the saved file wrapper, and then upon save I attempted to copy these all into the filewrapper...
What I found was that the files were indeed copied into the wrapper with the file structure I wanted, but when the actual wrapper was saved, these files all magically disappeared.
Great.
So, I trashed my existing solution and tried to use file wrappers instead. This solution involved creating a content wrapper file directory when a new document was created, or loading in a content directory file wrapper upon opening a document.
When an image was added/modified, I created the necessary directory wrappers inside this root content wrapper (i.e. an images directory wrapper if it didn't already exist, or any other intermediary directory wrappers that needed to be created) and then created a regular file wrapper for the media, removing any existing wrapper for that file name if one was there.
Saving the document was just a case of making sure the content file wrapper was added to the document file wrapper, and the document would save.
Well... it did. The first time. However, any attempts to make any subsequent changes i.e add an image, save. Then replace image, save. Did not behave as expected, only showing the image from the first save.
So, my question is... first of all, which of the above approaches is the correct one, if at all, and what am I doing that wrong for them to fail.
And secondly, as I expect to be managing 1000s of images, is using file wrappers the correct way to go about things at all.
With that much media in play, you should likely give your users control over whether the media resides in the document or only a reference to the media is included in the document, and the media resides elsewhere, such as in a library/repository managed by your application. Then they could save out a (potentially many times larger) copy with all references resolved.
You might want to zip/unzip any directory so that users don't get confused trying to attach the document to an email. I believe iWork has been doing this with its document bundles for a while now.
As far as what you are doing wrong, no-one can say, as you haven't provided any code demonstrating what you are doing.
Why don't you create a one-off application that lets you select files on disk and saves those files in a document using a file wrapper? This would let you tackle this functionality without any interference from other issues in your application. Once you understand how to use file wrappers, you can port the code back or just write new code that works.
I am attempting to add a document storage module to our AR software.
I will be prompting the user to attach a doc/image to thier account. I will then put a copy of this file into our folder so that we can reference it without having to rely on them keeping the file in its original place. This system is not using a database but instead its using multiple flat files.
I am looking for guidance on how to handle these files once they have attached them to our system.
How should I store these attached files?
I was thinking I could copy the file over to a sub directory then renaming it to a auto-generated number so that we do not have duplicates. The bad thing about this, is the contents of the folder can get rather large.
Anyone have a better way? Should I create directories and store them...?
This system is not using a database but instead its using multiple flat files.
This sounds like a multi-user system. How are you handing concurrent access issues? Your answer to that will greatly influence anything we tell you here.
Since you aren't doing anything special with your other files to handle concurrent access, what I would do is add a new folder under your main data folder specifically for document storage, and write your user files there. Additionally, you need to worry about name collisions. To handle that, I'd name each file there with by appending the date and username to the original file name and taking the md5 or sha1 hash of that string. Then add a file to your other data files to map the hash values to original file names for users.
Given your constraints (and assuming a limited number of total users) I'd also be inclined to go with a "documents" folder -- plus a subfolder for each user. Each file name should include the date to prevent collisions. Over time, you'll have to deal with getting rid of old or outdated files either administratively or with a UI for users. Consider setting a maximum number of files or maximum byte count for each user. You'll also want to handle the files of departed users.
