If I have a folder with a bunch of ".htm" & ".html" files in it and I use
My.Computer.FileSystem.GetFiles(myFolder, FileIO.SearchOption.SearchTopLevelOnly, "*.html")it returns all the ".html" files, as expected. But if I useMy.Computer.FileSystem.GetFiles(myFolder, FileIO.SearchOption.SearchTopLevelOnly, "*.htm")it returns ".htm" & ".html" files, when I would expect it to return only the ".htm" files. Is this a bug?

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.

There is a lot of duplication of functions in the My.Computer.FileSystem and System.IO.File namespaces.
So what exactly is the difference between: My.Computer.FileSystem.CopyFile(strSource, strDest, True)
and:System.IO.File.Copy(strSource, strDest, True)
Is there a performance difference? What is everyone's opinion on which which has the edge on read-ability? I personally use the My.Computer Namespace but that is just habit now.

I'm trying to read a file line by line. Right now I have...
My.Computer.FileSystem.OpenTextFileReader(strList).ReadLine() But I keep pulling the first line, not the next line and so forth, anyone know how to do this? I want to stay with the My.Computer namespace because it is thread safe.

What are the differences between these two methods that appear to carry out exactly the same function?
Is there guidance to say which should be used or are there conditions when you may use either?

Do you know how to declare a variable that can hold the result of a call to GetFiles?
I don't know how to do this, so I am using the following verbose/duplicative version:
Dim l_v_String_FoundFile As String
If My.Computer.FileSystem.GetFiles("A:u_Au_W", FileIO.SearchOption.SearchAllSubDirectories,

This has to be simple, but can't find the answer.I want to display a list of all files from a folder in a listbox. Easy..., but I want to display only the filenames without their paths.
For Each foundFile As String In My.Computer.FileSystem.GetFiles("C:My Folder")
ListBox1.Items.Add(foundFile)
Next
This gives me list looking like that:
C:My Folderfile1.txt
C:My Folderfile2.txt

TempUserPath = My.Computer.FileSystem.SpecialDirectories.MyDocuments Returns the string "C:UsersOwnerDocuments" but that folder is actually named "My Documents" (i.e., is "C:UsersOwnerMy Documents" in the Finder).When I try to create a new folder called "Documents" in the Owner directory, Windows asks if I want to merge its contents with the My Documents folder. If I say yes, I am left with only the My Documents folder and none named "Documents".Thus when I attempt to read or write a file to the TempUserPath location, I get an "access denied" error. This happens even after I manually change the name of the folder from "My Documents" to "Documents".

if they choose to use a networked version of my software, I will need the main server doing the authenticating. This is a problem, because from what I understand, it is quite easy to clone MAC addresses. I have looked into using the CPU ID and the HDD ID, but those are not unique, well at least I don't think so. Reason why I say they are not unique is because someone has the exact same CPU ID as me, and the HDD ID changes from partition to partition (same drive). Maybe the HDD ID is a partition ID instead? Anyways, I was thinking maybe I could get the Physical serial number of both the HDD and CPU, but I have not been able to find anything yet.

I created a background image for the form with rounded corners. I filled the outer edges and empty space with Lime color (00FF00) and then set the same transparency key in the properties for my form. It worked well, the edges were transparent and the form appeared round-edged. This was accomplished with Visual Studio .NET 2005 on Microsoft Windows Vista Home Premium 64-bit.The very same application was ported to a different platform. Visual Studio .NET 2005 on Microsoft Windows XP Professional 32-bit. All the settings are the same and nothing has been changed. But the transparency effect is not appearing on the Windows XP platform.

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.

It seems like FileSystem.GetFiles() is unable to recover from the UnauthorizedAccessException exception that .Net triggers when trying to access an off-limit directory.In this case, does it mean this class/method isn't useful when scanning a whole drive and I should use some other solution (in which case: Which one?)? Here's some code to show the issue:
Private Sub bgrLongProcess_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bgrLongProcess.DoWork

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.

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?
