VS 2010 FtpWebRequest - Check Directory Exists?
Oct 26, 2010
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 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 can't seem to work this out... I've got a program that references a network path. The problem is that the network files are not found when I run the program from various computers. If I have the user navigate to the network path directoy and then run the program it works perfectly.
The problem is that whenever the machine is restarted I run into the same problem and have to manually navigate to that path before the program will be able to find the files.
I then tried several checks to see if the directory exists but it's not working.

If My.Computer.FileSystem.DirectoryExists("\AB eamportalShared%20DocumentsJustin%27s%20AppsFeedback") Then

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.

I am currently using the below code to upload a file and display progress. It works fine except there are a few things I would like to do differently.
I am using the main FTP account for my website which has access to all of my files. I set up a different FTP login to use that only has access to a specific folder, but when I try to use it I get: Error 550 No such file or directory or access denied.
This FTP account allows access to: mywebsite.com/upload/users/ only If strFTPAddress = mywebsite.com/upload/users/ I get error 550, I've tried a few other things too and it's told me that it's an invalid URI
Basically what I want to know is if and how I might be able to connect using my second FTP account so that I only have access to the upload/users/ directory.
Code:

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 wanted to create a login system that would have 3 tabs 1 for regular login, 1 for admin login and 1 for account creation. So far so good. It saves the accounts by saving them in a .urs file in the map called /Users/. However when this map does not exist it will show a error. I would want to know what code or so to put into the form_load which will make my program create the map /Users/ if it does not exist. As im not familiar with all the codes and stuff. The only thing i can come up with is
Mkdir "/Users/"
but then ofcourse it would create the folder users everytime i start the program. not i was still "Hello Worlding" a few days ago, so i really am unfamiliar with any sort of high-skilled programming which i probably dont understand.

I tried this
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Directory.Exists("c: estDir1") Then
'shows message if testdir1 exist
[Code] .....
I am getting errors such as:
Exists is not a member of directory
CreateDirectory is not a member of directory....... and so on
How to remove these errors?

I am developing a Windows Service (Yes, windows service) using VB2008 and am having trouble determining whether a remote folder exists.The IF in question goes something like this:
If NOT system.io.directory.exists(strFolder) then
System.io.directory.createdirectory(strFolder)
End if
The problem is that the above test (excluding the NOT) always returns False, regardless of whether the folder exists or not. So, even if the folder exists, the next statement tries to create an already existing folder which does not go well.
The weird part(s) - after some tests
The system.io.directory.exists() works well when I type it in the immediate window for both local and network resources
It also works well when it is within a normal app (that is, not a service) regardless of whether it is local or network resource
The exists() method when in the service works well if the folder being tested is on the local machine, but fails when it is remote network resource, regardless of whether it is a true UNC or a mapped drive.It is not user's rights, as I have tested with both my own user and the localsystem user and have tested with network resources where I do have access rights.When I try to debug, the PC starts playing the Twilight Zone Theme (Ok, I am kidding about this one )Doing some searching I found that others are complaining about the same behavior, but no suitable answer has been found.

I'm building an application which require to use Directory.Exists on a network share UNC path. I know how to use that function, and how to implement it in my code, it's working perfecty locally.
Here my setup:
- VS2003
- .NET 1.1
- It's an Outlook Add-In
Here the code :
Dim realpath as string = "\myserverfolder$subfolder"
Impersonation.ImpersonateUser("admin", "DOMAIN", "adminpass")
Dim isDirExist As Boolean = Directory.Exists(realpath)
If isDirExist = False Then
Directory.CreateDirectory(realpath)
End If
Impersonation.undoImpersonation()
If I build this code, and register it in Outlook with my personnal account (admin), it's working fine, I receive true. If I build this same code, an register it in the Outlook of a normal employee (user only), it's always returning FALSE, no matter if the directory exist or not. The share is set to everyone allow, and I tried giving everyone access to the ACL, and it's the same result.

This is the standard way of checking if URL exists [code]....
return true; } catch (Exception ex) { return false; } But my problem is that we have to check it for around 100 URL's. It takes more then 2 minutes to check for all as it is trying to get response of all of them. Is there any way that we can check if URL exists without getting complete Response so that total response time is less.

I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

In my code, I want to check if a referrer url exists and if the referrer url contains a specific sub string. I know how to check for the sub string:
If( InStr( Request.UrlReferrer.ToString(), "some sub string here" ) > 0 ) Then
But I don't know how to check if a referrer exists or not. No refer exists if the url is entered in manually in the address bar. So I tried this, but this does not work:
If (Not (Request.UrlReferrer.ToString() = "")) And (InStr(Request.UrlReferrer.ToString(), "some sub string here") > 0) Then
how do check if a referrer exists?
