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

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

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

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.
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
Dim drive As DriveInfo[code]...
Consider the following snippet:
Dim Arext() = {"*.ttf","*.ttc"}
For Each foundFile In FileSystem.GetFiles(srcdir, SearchOption.SearchTopLevelOnly, arExt)
[code]....
The unexpected result is that not all the files specified in arext() are returned by this code. Running the same code twice on the same subset of files does NOT produce consistent results.I'm seeing, probably, 90% of the files with the other 10% not being included?
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.
I've taken a few vb courses a few years ago but I've been wanting to write a script that will search my harddrive(C:) for any ".dda" extention and list the location to a listbox. I eventually want the script to also copy the file to the location of the build but I can't seem to get the first part working at all. [code]A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll.

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 doing a project now. I'm having a problem on getting specific file type from my computer using the .getfiles function.
Here's my codes.

Dim filepath as String = "C:"

What I wanted to happen is when the openfiledialog prompted and once I've selected the file, the file information I've specified above must show on the application as a label. But nothing appears. The file name only appears on the text box beside the open button. It should also appear above the button and the text box as a label. How could i possibly do that? And how could I select just one file at a time from a folder with 150 other files in it? When I use getFiles, it only gets all at the same time everything that's in the folder even if i've only just selected one file.
If so, what is it? I am using VB 2010, and am relatively new to VB.
View 2 RepliesTempUserPath = 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 3 RepliesI 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?

I have vbscript code that enumerates user profiles from this registry path:
HKLMSOFTWAREMicrosoftWindows NTCurrentVersionProfileList.
How can this be done using Visual Basic 2010? Is there a class or method that I would use to accomplish the same thing or would I have to read the registry path into an array as you do with vbscript? My application will be ran on the local computer just so you know this information is not being gathered from across the network. I have been looking for awhile and haven't found anything that will work so far.Once I have the user profiles from the computer, I will populate this list into a drop-down combo box.

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.
