I 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 RepliesIt 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?)?

If 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
<asp:GridView ID="GridView1" runat="server">
[Code]...
...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'."
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?
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.
View 4 RepliesI am wondering if there is a simple method to filter the result returned by Directory.GetFiles(). Basically I am looking to retrive all of the jpg files in a selected folder into an array. My current code works fine if the folder only has jpgs in it which should be the case in operation but I would like to make sure it works correctly when the folder contains other types of files as well. The line I am currently using is..
Code:
files = Directory.GetFiles(IMAGE_DIRECTORY) files is defined as an array earlier in the program and as I mentioned my program works fine when the folder has nothing but jpegs within. The problem is that I am creating a listview with thumbnails from these files and run into some indexing issues when there are non jpgs in the target folder. The easiest solution would seem to be a filter on the getfiles method that would return only files witht he given extension.
Anyone know how to do this or will I need to parse the files out of the array in a second process?
When you do GetFiles() you can specify a search pattern such as *.txt. How can I specify multiple patterns. For example, in windows search you do *.jpg;*.bmp;*.gif. I tried that but no luck and the msdn not work. Is this possible?

Dim o As New System.IO.DirectoryInfo(Application.StartupPath() + "p") Dim myfiles() As System.IO.FileInfo
myfiles = o.GetFiles("*.r**")i have such code. for example I got 4 files in tmp dir. it's called file.rar, file.r00, file.r01 and file.r02 ,the return Array always comes as follow file.r00, file.r01, file.r02 and last is file.rar. Now I want the result in order like first file.rar and next is 00 01 02 03...n etc how to make it ? anyway dont make .rar in last I want to make it in the first place.seems there is a Array.Sort but I dont know how to use it this way.

im having some issues with getfiles, and i cant seem to pin point the cause, heres the issue:Im scanning a folder which has a mix of file types (.7z, .rar, .bin) and for each file im checking a dat file to see if that file (via the crc32) is listed in the dat. Pretty simple, but my code is randomly hit/missing heres what i have around my vb For Each strFile As String In System.IO.Directory.GetFiles(ComboBox1.Text, "*.*", SearchOption.AllDirectories)Next ComboBox1 .Text is a folder path for example 'C: est'
And inside of that i hae the crc32 code, the crc 32 code works great, the issue is with the above so no need to post lots of crc32 code. Now the problem im having is say i scan a folder with 10 files, lets say 5 7z's and 5 .bin's, sometimes the scan will scan all 10 files sometimes only 5 7z's and 1.bin, sometimes no .bins, sometimes only the .bins.If i put the .bins in a folder on there own and scan it will scan them all, same with the 7z's, so why is it not working when there all in the same folder?EDIT: I think the error is here 'SearchOption.AllDirectories' but i dont understand how to fix it, if i put all files into the root of the folder it will scan all of them, but i wanted to be able to scan the files in the subfolders to hence the SearchOption.All Directories, but it seem to be failing
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 use the following code but also include a variable.. Works...

I'm sure it's an easy fix.. I actually want to use the multifile option ie.. "*.mp3","*.avi" etc..
This is the code I have set up to scan a directory of files:
Dim fileArray() As String
fileArray = Directory.GetFiles(System.AppDomain.CurrentDomain.BaseDirectory & "help")
And it successfully gets all files in the directory, but it gets their absolute paths as well. For example, one of the entries in fileArray() is:
F:ProjectProjectinx86Debughelpook_troubleshoot.html
And I want it to just be:
book_troubleshoot.html
Is there a way to do this without parsing through all the array entries to trim off the path?
I have a program that uses the Folder Browser Dialog... I am currently using it to GetFiles and list them in a list box... Currently, it searches directories and subdirectories to get files with a specific patter. I would like to either have the files show with their paths, or return a list of the directories to work with later on... Using the Get Directories method I beleive it creates an Array but I am unfamiliar with how to manage the list it returns. I am also having an issue when the user selects cancel the code continues running for the get files method and throws an error.

When I have a directory setup with a subdirectory and both the top directory and sub directory have files in them I get a list of all the files with no directory info. That's OK, but I need to restore them to another location with the same directory structure in place. I'm essentially copying all files in a directory and it's subs to another location. The problem is the sub directory info is not in the files list so everything goes into the main directory. How do I get around this or can I? Here is what I'm using now.
I have a directory, NewProg in Program Files and a sub directory under it called Sub.

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.
I have a directory 'C:Test' with three files in it:
A23456789.txt
A1.txt
G 5.txt
And I run this command:
Dim FileArr = Directory.GetFiles("C:Test", "*1.txt", SearchOption.AllDirectories)
All three files are returned.I understand that this is by design and .NET searches the 8.3 short file names as well.But is there any way to override this and search the actual file names only?Surely, in this day and age there must be a function to do this. Or do I have to write my own?I would like the search function to have the same behavior as the Windows Explorer for consistency.
