I'm running Visual Studio 2005 SP2 on Windows 7. When I'm in the IDE and execute a My.Computer.FileSystem.FileExists, or DirectoryExists or CopyDirectory, etc. that accesses a network drive using the drive letter (i.e. L:) it thows an error. If I use the full UNC (\computernamesharedfolder) it works. However, if I go into my project's bin folder and run the compiled .exe from there, the drive letters work. I've tried running VS.Net as admin and it makes no difference. How do I get the drive letters to work in the IDE?

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.
My.Computer.FileSystem.GetFiles(My.Computer.FileSystem.SpecialDirectories.ProgramFiles, FileIO.SearchOption.SearchAllSubDirectories, "MSAccess.exe")

I'm sure it's an easy fix.. I actually want to use the multifile option ie.. "*.mp3","*.avi" etc..
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:

View 2 RepliesThis 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".

View 5 Repliesif 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.

View 6 RepliesI have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,
So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?
My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.
I'm trying to determine if a file "G:myfilesfile1.txt" exists. Using sample code from numerous web searches I can't make any of the FileSystemObjects work. Seems to me the FSO routines are an add-in to VB. If this is so, how do I add them in?
In noncode, this is what I really want to do:
if "file1.txt" exists AND "file2.txt" exists
if "file1.txt" filedate > "file2.txt" filedate
copy "file2.txt" to "fileold.txt"

I wrote an application on windows XP using visual studio 2008. Based on the .net framework 3.5. For some reason that I do not understand the application refuses to run on windows 7. You would think that if the .net framework 3.5 was installed on the windows 7 machine it would run.
