VS 2010 How To Check Whether Files Are Being Accessed Before Do Directory.Delete
Apr 5, 2012
I'm copying over some files to a target directory on a daily basis.Before I move the new files over, I'd like to delete the old files under the target folder, possibly using System.IO.Directory.Delete()But my problem is, the target folder is on a public drive where everybody in the company could access, and I don't want to empty the folder while someone else might be using those files.I'm thinking whether there's a Class that check the status on the files in a specific directory before I come in and delete everything.(I know I would get an IOException if I disregard the status of the files and try to delete them)

I'm working out on a function in my program to let it update all the downloaded files by a button, I tried this:
[code]...
But when I try it .. It says that I cannot remove the directory because it already has files inside it.My question is, how can I remove all these files together (Without mentioning each one of them because they're about 100 files) so I can be able to delete the directory?

I'm trying to read a csv file. I'm also try to delete all files in the temp directory on the page load. Everything goes fine the first time, but the second time I get an error saying it couldn't delete the file because it is in use by another process. I'm aware that this process is my vb file, I just can't seem to find what I need to dispose of to get rid of the file lock.
Here is my code
Imports System

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

I want to have a windows application that would check a specific folder for any files, and if there are any files I will run some code to each file, I was going to use a timer and set it to refresh every 15 seconds or so but I am not sure if there are any other ways to do this that would not take up as much resources.

Suppose I have an IEnumerable such as a List(TValue) and I want to keep track of whether this list is being accessed (to prevent issues with, say, adding to the list while it is being iterated over on a different thread); I can always write code such as the following:
Dim List1 As New List(Of Integer)
Dim IteratingList1 As Boolean = False
' ... some code ... '
[Code]....
(I realize this code is very arbitrary, but it illustrates what I'm talking about.)
My question is whether there's a better/cleaner way to perform this check than by manually updating and accessing a Boolean, as above. I feel like there must be, but, to my knowledge, there isn't any IEnumerable class with a built-in "I am being iterated over" method or property. And writing a new class that implements IEnumerable and contains such a property seems like overkill to me.

I have a security timer to check if the directory exists which I want to access after it's been created by an external application, but what I have done doesn't seem to be the solution although it sounds like a very normal solution to me.
What I have done:
1) External application gets run which is going to create the directory
2) I set the variables to make the timer able to know what to check
3) My application needs to wait till the boolean variable gets set to true, so I put it in a
While:
vb.net
'Non existing files protection
While (Not bDirectoryExists)
If bDirectoryExists Then
Exit While 'In case it got created in the meanwhile
End If
If Not tmrFileCheck.Enabled Then
tmrFileCheck.Enabled = True
End If
End While
4) In my logic, the application should go out of the while now because the variable is set to true, and the code moves on, which never happens..

I'm having trouble finding a reliable method to check if a directory (folder) exists on an FTP server. I want to create new directories and then upload files into them but thought it best to check if the directory already exists. Although attmepting to create a directory that already exists does not seem to cause any errors, it does waste a bit of time.
This code reliably checks if a FILE exists:
[code...]
I have attempted to modify this with ListDirectory in place of GetDateTimestamp (to check if a directory exists) but it seems no exception is thrown whether the directory exists or not. I've done lots of Googling but haven't found a satisfactory answer.

I am trying to program my application in VB.Net so that when a user goes to my 'FTP Out' page, the page straight away loads with a list of the files that are on my FTP site.I know I will have to get a connection going with my FTP site but how do I actually go about getting the list of details to show on my form?
At the moment, all I can think of is calling 'Methods.Ftp.ListDirectoryDetails'

I'm trying to delete all the files in the same folder that have the same name but different extensions, such as CurrentWallpaper.bmp, CurrentWallpaper.jpg, CurrentWallpaper.png, without putting them in a separate folder. How could I go about doing this? I tried doing
Dim bg As String = dir + "" + Login.UsernameTextBox.Text
Kill(bg + "CurrentWallpaper.*")
but it didn't work. PS: I would also like to use the same technique for loading the image as a background image instead of having to do this:
Try
If My.Computer.FileSystem.FileExists(Login.UsernameTextBox.Text + "/CurrentWallpaper.jpg") Then
Me.BackgroundImage = Image.FromFile(Login.UsernameTextBox.Text + "/CurrentWallpaper.jpg")
End If

I need to delete older bkf files in a directory, only leaving the newest 20.
No, I can not just delete older than x days because there can be more than one backup file per day and some times it may be 2-3 days before a backup file appears.

I currently have a bunch of text files I need to edit in a folder, I need to edit each file and remove the same line but not all files have this line, so I need to create a script that needs to check if the line exists then remove it.I have 1000s of files, that's why I need help to be able to create a script that does it for me instead of me editing each one manually.I am not sure on how to do this, but I am sure it is not difficult for people that have good experience with VB.net.
