VS 2010 GetFiles - Getting Error 'SearchOption.AllDirectories'?
Nov 18, 2011
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

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.
files=dir.getfiles("C:Program FilesNewProg",searchoption.alldirectories)
My.Computer.FileSystem.CopyFile("C:Program FilesNewProg" & File.Name, "C:NewProg" & File.Name,True)The Sub directory is not created and even when it is there, it always comes up empty with all it's files copied into the main NewProg.

I'm getting an access denied error when I run this code:
[code]...
If I change SearchOption.AllDirectories to SearchOption.TopDirectoryOnly then the code executes without any errors and the files in the top Directory are displayed. Apparently there is an access method that I need to set but I'm not sure how to implement it into the existing code.

I am having a problem with my application which I recently created. The application was designed to search for files either recursively or non recursively for files with certain attributes ie. file size, date created, etc. The application works (well sort of)....
I currently have the application creating a tmp file using IO.filestream and IO.FileMode.Create and then I'm using StreamWriter to write the names of all the files that are found with the matching attributes to the tmp file that was created in the tmp directory. What I have found is this:
If the parameter to do a search recursive is True then the names of the files through the directory tree are successfully written to the tmp file and all is well however if the base path specified does not contain any sub directories and searchoption.alldirectories is used I cannot get any of the files names who match the search criteria to be written to the temp file. If I add a console.writeline(sfile) just above the call to write to the temp file the names are written to the console successfuly (just like they should be to the temp file).
If I choose not to do a recursive search and specify using SearchOption.AllDirectories then I see a similar problem...none of the files in the top level directory that meet the search criteria are written to the tmp file like I'm telling them to. Again if I add a console.writeline just before the call to write to the temp file the names of all the files in the top level directory are written to the console successfully.
I cannot figure this one out...I am stepping through the code with the debugger and based on what I'm seeing I should not be having this problem. I know the logic is correct because I can write it out to the console correctly...

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]...

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

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

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.

I 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?

I'm trying to load the most recent file from a directory, but my following code doesn't work. Am i getting something obvious terribly wrong?!
Dim myFile = Directory.GetFiles("C:UsersJoeDesktopXML Logs").OrderByDescending(Function(f) f.LastWriteTime).First()
I get two error messages:
Data type(s) of the type parameter(s) in extension method 'Public Function OrderByDescending(Of TKey)(keySelector As System.Func(Of String, TKey)) As System.Linq.IOrderedEnumerable(Of String)' defined in 'System.Linq.Enumerable' cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
And:
'LastWriteTime' is not a member of 'String'.

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.

In the code below I got a UnauthorizedAccessException unhandled, access is denied to the directory
'c:WindowsSystem32LogFilesWMIRtBackup'.
A first chance exception of type
'System.UnauthorizedAccessException'
occurred in mscorlib.dll.
How can I make the search only in allowed access directory's???
Dim searchResults As String() = Directory.GetFiles("c:", "*.idw", SearchOption.AllDirectories)
For Each result As String In searchResults
MessageBox.Show(result)

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?

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?
