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'm hoping to improve the performance of the below as well as return the GUID of each user.
I've converted and modified the code found here for searching through groups recursively to get all the members and their details and adding them to a class collection. However I also need to capture the user's managers details so I'm calling the AD twice for each user. This doesn't seem efficient as many of the users will have the same manager. It would seem logical to get the distinct manager details from the collection class and call only these, then replace them wherever they occur in the collection.
I'd also like to be able to get the user's GUID, I've tried accessing it directly as a property of the collection, but it doesn't return anything.
I'm using vs2005 and .Net 2.0

I am trying to write code to save (in a text file) a list of folders/files that are contained in a specified folder. I want the list to be formatted to illustrate the folder tree structure by indenting sub-folders and there related files according to their relationship to the base folder.
I found and incorporated a recursive function for listing file & folders. This works fine for generating the list, but I am having difficulty with code to determine the sub-directory level relative to the base folder. the code that I have included below sort of works.......The problem seeme to be when going from a folder that is multiple levels up? from the base to one that is only one level from the base. Refer to my sample output. This should not be as difficult as I seemed to have made it, but recursion kinda blows my mind.
Code:
' The following function call is in a button handler
GetFilesFolders(txtBaseFolder.Text)
Public Sub GetFilesFolders(ByVal path As String)

I have the below code that (not sure exactly where I found it) I am trying to add a recursive rename to all files in the directory. Currently, this code only does a folder at a time, however, I need it to go through all the folders and change all files.

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()

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.

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.
View 14 RepliesI am using the following Recursive Directory Copy code, and am having a strange issue. I am using this to copy and directory and all subdirectories and files to removable media (flash drive). Everything copies perfectly fine except for 1 file. this occurs on the same file every time and sometimes the file copies successfully, but other times it does not.The problem file is a 7-zip archive with a .7z file extension.When it does not successfully copy, the file is only 8 bytes on the flash drive.[code]

View 3 RepliesI am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:

I have 3 variables. Lets call it "a", "b" and "c". These 3 variables can "independently" have 3 different values. Lets say: "1", "6" and "10". when you think of them as combination; there are (3^3) 27 combinations. I am told that it can be done through the recursive functions. However i am not a good developer to handle with that. Would u please help me?
- 3 variables and 3 different values are simplified. In fact; the numbers of variables and different values can vary.
- i know only the language, visual basic in .net; please don't answer in other coding languages.
additional note: i am going to put the these combinations in the string format into a collection.. for example "1;1;1", "1;6;1", "1;6;10".. and so on..
I have a recursive function wich objective is scan an structure and represent that structure with treenodes.

I want to rewrite it so it would only be loop and no recursion and I'm currently lost?I'm passing a class to this function(with a starting value for found as false) to know if it is linked to the middle of the tree. The class got an array with a maximum of 4 link to other class and it can be circular(this is why I have a checked_link boolean).It does the recursion until there is no more link(return false) to check or until it find the middle link(return true).
edit?for an example, this
in pos 0 got link with 1
in pos 0 got link with 6
in pos 1 got link with 0
[code]....
middlepoint would be pos 15 the code above can prove that every position can be linked with the middlepoint so initial arg would be
everythingLinked(random pos, false)
and in this case it would be always true
