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")

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

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've tried to use SHELL to run an program when i hit "Button1".I reckoned ill use the Computer.FileSystem.GetFiles.To find the File on the Users Computer. And i dont know how to transfer the data Computer.FileSystem.GetFiles obtains to the Shell.[code]

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.FileExists(g_DbFolder & "MyDB.sdf")returns false for this existing database in Windows 7 64bitYet when I boot back into Vista Ultimate/(rip off) 64bit the database is properly detected.
View 9 RepliesI'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?
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:"
dlgOpen.CheckFileExists = True
[CODE]...
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 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 5 RepliesI used the GetFiles function in the following code:
frmConvert.ListBox20.DataSource = My.Computer.FileSystem.GetFiles("c: empparse")
I need to do the exact thing as above but into an Array and not using a ListBox.
I can't figure out how to use the (because im noob)ystem.io.directory.getfilesIf I try to put it in a textbox for example textbox1.text = system.io.directory.getfiles("my directory") then I just get the error message "Value type of '1-dimensional string of array' cannot be converted to 'string'. First of all I have no idea what the '1-dimensional string of array'thing is.And if I try to put in a msgbox for example sgbox(system.io.directory.getfiles("my directory")) then I can run the program but when I click my button then it says "it can not convert argument prompt to string(google translated)". And second, I don't know what the prompt thing is either

View 2 RepliesIf I want to bind the files of a folder to a gridview, I can just do this:
GridView1.DataSource = New DirectoryInfo("C:MyPix").GetFiles
GridView1.DataBind()
...And this asp.net

...But if I want to bind it to a repeater in stead, I would think I could display the filename like this:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate><%#Container.DataItem("Name")%></ItemTemplate>
</asp:Repeater>
...But that gets me the error "No default member found for type 'FileInfo'."
How do I (i) sort the array of type FileInfo returned by the DirectoryInfo.GetFiles method by (file) CreationTime in descending order and (ii) once the array is sorted efficiently load it or convert into a Queue object (of type FileInfo) for subsequent processing. I thought of using the queue object as it handles things on a FIFO out basis and I'll be adding to the queue as new files arrive.
