However to be sure the code works with other potential implementations of versioning VPPs it is more correct to do the checkin, checkout operations explicitly.

App also handles Windows file cache so it doesn’t interfere. Only other parameter to choose is test file’s size (defaults to 100MB) so you can both run quick or prolonged tests.

It has nothing to do with background theory and everything with real file transfer. Note: The FileShare part is needed in the case of native files, in wich case you open two streams to the same phycisal file.Īnother thing to notice about versioning files is that the EPiServer implementation of versioning files will automatically checkout the file when File.Open is called with FileAccess.Write (if not already checked out) and in that case it will be checked in when the stream is closed. App writes file to chosen folder and reads it back. Using (Stream writeStream = file.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite)) Using (Stream readStream = file.Open(FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) Write, FileShare.Read ) //Create StreamWriter object to write string to FileSream StreamWriter sw new StreamWriter (fs) sw.WriteLine('Another line from streamwriter') sw.Close() Read and Write operations are not possible on the same FileStream object simultaneously. UnifiedFile file = (filePath) as UnifiedFile The following is a code example that would work both for native and versioning files: Creates a file with read-write access that allows others to read: 15.9.6. Use FileStream with StreamWriter to provide a greater degree of control in how you open the file: 15.9.5.

So if you like to update an existing file the way would be to get a read stream to the previous version and get a write stream to the new version. FileStream is opened for FileAccess.ReadWrite FileShare.Read and has had its entire contents truncated (due to FileMode.Truncate) 15.9.4. I will report a bug that FileMode.Open in case of new version should be treated as FileMode.OpenOrCreate.Īnother thing to notice about versioning files is that the stream returned when Open is called with FileAccess.Write is a stream to a new version with consequence it will point to an empty file. However the physical file for the new version will not exist, therefore open the file with FileMode.Open will throw FileNotFoundException, if you instead open the file with FileMode.OpenOrCreate you will get a stream. The reason your code does not work for a versioning file is that if you open a file with FileAccess.Write you will get a new version of the file. Users will be able to browse to the server hosting the share, and they will see the share name, but when they try to browse the share itself, they will receive a “Network Error” stating Windows cannot access the share because the user does not have permission.The code you wrote works well in case the file is a NativeFile, however in your case the file is a versioning file (I assume that from the error). Now users can read, write, and delete files in this share, but they cannot browse its contents. Assign the second Special security permission by clicking Add, select the “Application Users” group, configure “Apply to” so that it applies to “Files only,” and then check the following permission only:.

Assign the first Special security permission by clicking Add, select the “Application Users” group, configure “Apply to” so that it applies to “This folder, subfolders, and files,” and then check the following permissions:.

At this point, you may want to add an administrator group like “Domain Admins” and assign full permissions for administrative purposes.

Go to the Security tab, then Advanced, then Edit, and uncheck “Include inheritable permisions from this object’s parent” and then Remove all permissions from this folder.

Assign the “Application Users” group “Change” and “Read” share permissions.

Create a folder and go to its Properties and then to the Sharing tab and then go to Advanced Sharing.

These directions assume all users of this application are members of an example group called “Application Users.” Obviously you can use whatever group you want. Note: Using this method, users can still read the actual files if they happen to know the file name, they will simply be unable to get a directory listing of files. To set up permissions for a Windows share so that users can read, write, and delete files in that share, but not list the contents, you will need to configure share permissions along with two “Special” folder security permissions. This of course is a horrible way to do things, but you are at the mercy of the application. Users will only have access to the files in this repository via record access within the application. And all users of this application need the ability to read, write, and delete files in this directory, but given the sensitive nature of some of these files, you don’t want users to be able to browse to this directory and see a list of files.

In other words, the application uses a simple Windows share for its file repository. Let’s say you have an application that has a flat file repository for files attached to records.
