VS 2008 Returns A Value Of The Numbers Of Files - Folders And Subfolders In A Directory - Error "UnauthorizedAccessException"
Aug 25, 2009
I have a function that returns a value of the numbers of files, folders and subfolders in a directory. But i can't seem to handle the "UnauthorizedAccessException" which i get from certain read only files or folders. I tried to use both the DirectoryInfo.GetDirectories() and DirectoryInfo.GetFiles() methods. as you can see from the code below. This exception is thrown in start of the for each loop, so i'm not able to handel it with a try, Catch Ex As UnauthorizedAccessException to cintinue the loop.
This is driving me crazzyy. I need a simple way to display all of the folders and subfolders of an FTP directory in a treeview, similar to the layout of Windows Explorer. Here's the code I have:
[Code]...
The code is total crap... causes my app to hang. Pretty sure infinite recursion is the cause.
I'm working on an application, in which the first step is to append all files in a folder selected through FolderDialogBox.It works perfevtly.There is a change in the requirement now.The change is, all .txt files within the selected folder and .txt files in the subfolders of the selected folder has to be
Dim theDir As DirectoryInfo = New DirectoryInfo(inputPath) Dim theFiles As FileInfo() = theDir.GetFiles("*.txt")
coders within the program i'm coding right now I would like to generate an arraylist of all files within a folder, its subfolders and those subfolders subfolders.These are the functions i have to generate an arraylist of all folders in a folder along with all files in a folder is there any more simple way to just search every file within a folder including all subfolders, and subfolders of subfolders?
I have been trying to get a .jpg files from subfolders that get's updated and a new subfolders is created. I have been trying to figure how to code to read the folders/subfolders and to get the .jpeg files copy or move to different folder.
I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase If f.Exists is False, mark it as deleted in the database Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?
I would like to know how to delete all files and folders under a certain directory. For example if I wanted to delete all files and folders in C:est how would I do that?
VB.net 2008 express This is what I have so far, and it loads a list of files from a text file. Now I need to be able to delete them all from a certain drive and all sub folders in it. For instance I push the delete button and it goes through the entire list and deletes all the files in it from the designated drive and all it's sub folders.
Code: Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code "
in windows; when you right click over a folder you can know how many subfolder available (the total number) is there a way to get this number using simple code i am using vb2008
I want to show a list of files and folders (names + their icons) inside a given directory with a ListView control or equivalent. I understand that ExtractAssociatedIcon gives you the icon of a file, not a folder. So what are my options for this objective? I don't really have a problem if I have to separate folders and files like the following.
Dim fi As New IO.DirectoryInfo(f) 'f is the path of a given directory For Each subfolder As IO.DirectoryInfo In fi.GetDirectories() ImageList1.Images.Add(My.Resources.FolderIcon)
I am currently using a recursive function to retrieve all the files/folders within a directory.Sometimes this takes a while. I am wondering if I am able to calculate the total number of files/folders within a directory before retrieving the filenames so that I can implement a progress bar?
I have two folders at different locations but with the same name. A file is generated in one of the folders and it is to be copied to the other folder but without overwriting the existing contents in C#.File.Copy overwrites the contents which makes me lose the previous contents. Is it possible to merge the contents in the folder?
I wrote a Windows Forms script that searched for all non-hidden and non-readonly folders in my system. But the script itself, when run initially, runs for like 5 minutes. Subsequent opens take much less time. I was wondering if there is a logical error to it, so as to why its running so very slow.
Private Function FindSubFolders(ByVal dir As DirectoryInfo, ByVal node As TreeNode) As TreeNode Dim subnode As New TreeNode For Each folder As DirectoryInfo In dir.GetDirectories()
I need to create 3 folders (named as In,Proc,Error) in C:Ram directory. First I need to check for folder existence in directory. If any of them not present need to create missing folder. If all missed need to create all 3. Could anyone suggest a simple looping code in VB.NET for this requirement .
I'm trying to make a program that will list all the sub-directories in a directory then list all the files in a sub directory in another listbox when you select a directory from the first listbox, what I am stuck on is listing the folders.
Dim folderInfo As New IO.DirectoryInfo("c:windows") Dim arrFilesInFolder() As IO.FileInfo Dim fileInFolder As IO.FileInfo
[Code]....
This code lists all the files in a directory but not the folders, I want it to do the complete opposite.
I got a file to copy using vb.net 2.0 from another server to a local folder:
dim source as string = "\servernameshared directoryindex.htm" dim destination as string = "D:/local folder/index.htm" system.io.file.copy(source, destination, true)
ListBox1.Items.Clear() Dim di As New IO.DirectoryInfo(TextBox1.Text) Dim aryFi As IO.FileInfo() = di.GetFiles("*.*")[code]......
and that displays only the file name, like text.txt but i want it to display C:/Text.txt and all the files in the subfolders too, like C:/Program Files/Test2.txt but i just get test.txt from only the c:/ .
I need help with file enumeration. I'm trying to create a program that can list files, folders and sub folders locations in a log file for diagnostic purposes. After it searches it can open notepad and display the results. The problem I'm having is that I'm a beginner and not familiar with file enumeration.
I'm using the following code to get all of the files from a DVD drive and load them into a bindinglist and then a datagridview:
mAddBL.Clear() ' Try Dim dir As New IO.DirectoryInfo(Form1.m_DVDdrive & ":")
[Code]....
This shows all files and folder names on the disc. If I want it to show all files, regardless of the folder they're in, is there a built-in method to do that or do I need to take an entry, identify it as a directory and then use that as my source to read the files in it?
I'm trying to search a folder and it's sub folders for a file and add those files to a datagridview. I think the code I have is right but I need to get some of the files info, like the name and what not. since I've tweaked it it doesn't work.
I have a function that imports files from a folder and puts them into an array. The problem is: the files from the subfolders aren't included.
Public Function GetFilesByExtensions(ByVal strPath As String, ByVal colExtensions() As String) As IO.FileInfo() Dim tmpCollection As New Collection For Each strExtension As String In colExtensions
I am trying to create a program which will read the files that exist in a directory, and then write in a text file the specific information (full file name, date created)i have found several code in the site but i cant make it work, the machine i am running the code is XP and i am using VB2008.The code i have found is the following:
I have a program that copies files listed in an excel file and adds two columns together to rename the file when it is copied. This all works perfect. What I am having difficulty with is when the files are copied and renamed - I can't get it to find files in subfolders and copy them also. I have a text file that is created letting me know what files were not copied and the subfolder files are always on there?
