Storing Files In Database Vs Doing So In Filesystem?

Jan 30, 2009

I am in front of a great dilemma whether to store files in Database or doing it the standard way. I would choose the second option, but my application will be used by multiple users, so I am doing it by Web Services.

On the one hand, storing in database will be very useful as every user would have access to everything very fast, not caring about file paths, locations and so on.

On the other hand, if this table consists of 1000 files, wouldn't it be a bad idea as there should be some performance loss?

At the present moment, I am using mysql as database, but I am thinking of moving to SQL Server, but I suppose this is not DB Issue.

Files From Resources To Filesystem?

Aug 18, 2009

I have multiple .mp3 files that I have added to the resources of my project, and the thing is, that the mediaplayer won't play .mp3 files from the resources, so I need to extract them to the filesystem in order to play them, but I can't find any way to do this. All the things I've tried have given me the error saying that I don't have access to the folders I try to extract to. And yes, I'm on the Admin account of the computer.

.net - Computer.FileSystem.DeleteDirectory() With Read Only Files?

Sep 23, 2010

I recently came across a problem with My.Computer.FileSystem.DeleteDirectory(). It will not delete read only files.I found out by Googling that I could delete the read only files by changing the file attributes to 'Normal'. So I wrote a recursive function, as below.

Private Sub DeleteDir(ByVal dir As DirectoryInfo)

For Each d In dir.GetDirectories
DeleteDir(d)[code].....

It seems to work fine, but it would be nice if My.Computer.FileSystem.DeleteDirectory() had another parameter to delete read only files, or there was an easier way to do this.

Use The Filesystem Watcher To Monitor A Folder On A Ftp Site For Files Added

Mar 26, 2010

I am trying to use the filesystem watcher to monitor a folder on a ftp site for files added. Does anyone know how to do this? I have even read that the filesystem watcher was not meant for ftp's but rather local monitoring, which doesn't make sense to me.

C# - Winforms Document Manager Using Filesystem And SQL Database?

Jun 28, 2011

I am trying to create a document manager for my winforms application. It is not web-based.I would like to be able to allow users to "attach" documents to various entities (personnel, companies, work orders, tasks, batch parts etc) in my application. After lots of research I have made the decision to use the file system to store the files instead of a blob in SQL. I will set up a folder to store all the files, but I will store the document information (filepath, uploaded by, changed by, revision etc) in parent-child relationship with the entity in an sql database.

I only want users to be able to work with the documents through the application to prevent the files and database records getting out of sync. I some how need to protect the document folder from normal users but at the same time allow the application to work with it. My original thoughts were to set the application up with the only username and password with access to the folder and use impersonation to login to the folder and work with the files. From feedback in a recent thread I started I now believe this was not a good idea, and working with impersonation has been a headache.I also thought about using a webservice but some of our clients just run the application on there laptops with no windows server. Most are using windows server or citrix/windows server.What would be the best way to set this up so that only the application handles the documents?

XML Files - Storing Information For Application

May 22, 2009

I am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.

My XML file looks like this
<Data>
<Login>
<UserName> (UserName) </UserName>
<Password> (Password </Password>
</Login>
<Applications>

C# - Storing Static Files To Be Shared Among Azure Roles

Sep 13, 2011

I'm trying to host some static files for access by an ASP.Net web role and a separate data worker role that are both running on the same deployment (they use a global static interface).

However, I'm unsure how exactly to 'host' them, I've tried using virtual folders via HttpRuntime.AppDomainAppPath, but it only occasionally works in debug mode. The files also don't seem to get packaged into the deployment packages made by VS vis CSPack (though this might be a separate issue, is it possible to fix this too?)

The static files in question are actually WordNet, which I'm using through WordNet.Net, If that makes any difference. I also need the solution to work in both the cloud deployment and the emulator (if possible).

Asp.net - Storing .Net ArrayList In Database

Mar 21, 2012

I have a vb .net ArrayList that I would like to store in one field on my Ms SQL 2008 database. Is it possible to put it in and get it back out as an ArrayList? I'm guessing i need to break down the Array some how and store it as a string, then rebuild it when reading back as i dont see any datatypes for sql that are for arrays. Which is a bummer for me! edit - The ArrayList stores a set of quote ID's. There is no limit to how big it is so it could hold 1 or 1001 different ID's

C# - Preserve RichText Formatting When Storing In A Database?

Aug 11, 2009

I've created a rich text box which stored the "textBox.Text" value in an SDF database. The storing works, but the formatting seems to be lost. Is this something that SDF databases can't handle? Do I need to store in binary or something? Not sure how to do that either.I'm using Visual Basic Express Edition with Winforms and writing in VisualBasic.NET btw This is how I store to the database:

Private Sub btnToolStripSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnToolStripSave.Click
Try
Me.Validate()
Me.SangerBindingSource.EndEdit()

[code]....

And this is how I insert the text in to the rich textbox

txtBoxText.SelectionFont = New Font("Verdana", 16, FontStyle.Bold)
txtBoxText.SelectionColor = System.Drawing.Color.RoyalBlue
