8/2/2012 4:36:37 AM -How to change FileStoreObject to work With Application server?
-How many files you can store in one folder and the system is not to slow?
Can this sample be upgraded with Application server and multiple folders in File Data Store folder?

10/12/2012 2:00:24 AM I tried to run this example but it crashes.
It occurs a fatal error when I try to append a file after creating a new "Standard File Data Demo" Item. The error occurs at the moment the file select box opens. I didn't found a way to debug it.
Do you have a glue what it could be?
My configuration:
Win7 64BIT, VS2010, v2012 vol 1.7, SQL Server Express 2008 R2
Thanks, Martin

11/29/2012 9:56:43 AM @Roger: I have not yet tested this module with the application server. It is a good idea, though. Thank you for your input, I have added it to my TODO list.
@Sander: It is quite complex a module to rewrite it in VB.NET, as well as maintain two versions later. Even though it is not in my immediate plans, you can either include the C# module project into your VB.NET solution (Visual Studio allows this) or rather use free or paid conversion tools.
@Martin: Thank you for your comment. Hm, it performs perfectly well for me. I also ran functional tests that passed locally. You are probably not using the latest version in this example. It would be great if you could create a separate ticket in the Support Center and attach the eXpressAppFramework.log file with the error details. Thank you in advance!
PS.
Sorry for the late reply, guys. In the future, it is better to submit a ticket directly via the http://www.devexpress.com/Support/Center/Question/Create link, if you experienced any difficulties with our tools.

11/21/2013 11:44:40 AM Hi,
I'm working with Images in XAF application storing user image file to file system. So I'm using FileSystemStoreObject and It work fine for me. However, I've some problem!
one - I'd like split and save user images in FileData\<mykey1> folder where mykey1 depends by Business Objects instance1,
user images in FileData\<mykey2> folder where mykey2 depends by Business Objects instance2 and so on.
two - I'd like show stored images like Asp.net Images Slides Control or a link item in grid view to open images.
Do you have any suggestion or example?
Best regards,
Gaetano

6/2/2014 9:47:03 PM Did the "StandardFileDataDemo" store file attachments in database?
Added By:
Dennis (DevExpress Support) at:
6/3/2014 2:24:48 AM @xaero: The StandardFileDataDemo class uses the FileData class that stores files in the database and which is a part of the standard delivery.
In turn, the FileSystemStoreObjectDemo class stores files in the file system with the help of custom IFileData implementations described in this example.

9/19/2014 4:11:17 AM Hi Dennis, thank you for the code - it works great in my web application (I'm only using the FileSystemStoreObject). I've made a mod to cover the case where the user has previously saved a business object and subsequently reloads it to edit the FileSystemStoreObject property, namely to pick a different file. In this case _tempFileName is not correctly populated and the old file is not deleted when the file is changed and the business object saved.
My solution was to add the following code to FileSystemStoreObject.cs
protected override void OnLoaded()
{
base.OnLoaded();
_tempFileName = this.RealFileName;
}
Hope this helps others and perhaps you could update your code if you also feel this is a good solution.

9/19/2014 5:21:49 AM Thanks for sharing, Steve. Would you please either record a video showing how to replicate this behavior with the original example or create a functional EasyTest script covering this scenario? This will help me better understand the situation and make changes, if necessary. Thanks in advance!

12/30/2015 2:07:35 AM Does this already work using Application Server? Given the correct credentials, will this concept work with Dropbox (in replacement to File System)?

It works great.
I have enhanced the
FileSystemStoreObject to have a Content property like in the BaseImpl.FileData class:
[C#]
[NonPersistent]publicbyte[]Content{get{returnFile.ReadAllBytes(this.RealFileName);}set{this.TempSourceStream=newMemoryStream(value);}}

3/16/2016 7:27:47 AM The deletion is not working correctly on the detailview. I hit delete, filed is deleted but gets an error message saying "requested objects canot be loaded, because they are abasent in the data store....". It works fine in the listview. Please check.

3/17/2016 2:11:50 AM @Chris: Thanks for your feedback. In the meantime, you can remove the DeferredDeletion(false) attribute declaration from the FileSystemStoreObject class as a solution.Added By:

3/17/2016 10:12:53 AM Dennis, is it possible to make the textbox(filename) bigger? I tried to set the width and height on detailview and no success. Right now it's just using one row and no way to set rowcount for this field. I want the textbox to be bigger so it's easier for user to drag and drop on detailview.

10/20/2016 5:37:28 AM If I edit an oject which uses an FileSystemStoreObject
AND
change the file name,
the old file remained and was
not deleted.
After I changed
LoadFromStream method to
[C#]
voidIFileData.LoadFromStream(stringfileName,Streamsource){if(fileName!=FileName)tempFileName=RealFileName;FileName=fileName;TempSourceStream=source;}
it works.
