I was looking online for a application that can delete a file more secure then. Kill(C: est.txt")Then i had a thought.Maybe i can make my own.Is it possible to make a secure file deleter in vb.net or should i look into C++
View 5 RepliesI am looking for maby something I am missing here in this code. My goal is to take the current user and delete there local settings/temp/ files. However some of these files are in use by the OS and that's what im running into a problem with. Here is what I have so far and it finds the dir easly and bam that's the brick wall access denied error because there is some files in there that are in use.

I want to make a fairly simple program that would prevent file deletion of certain folders andor files that i would input into the program. Say if someone tried to delete the file it would display an error message.
View 3 RepliesWhat would be the best way to input the password when uploading a file to FTP? The file gets uploaded behind the scenes without the user inputting any details (the username + password gets used)
So far I've used the network.upload method but the password is in plain text and obviously readable. I need to upload the file without anyone obtaining the password when doing so, would obtaining the password from a mysql database or some sort of encryption be better?

I am developing an application that Monitors a specific folder for file changes such as modify deletion, update, etc. The only problem I have is , the application doesn't fire up File events.
Here is the code:
Imports System.IO
Imports System.Diagnostics
Public Class Form1
[CODE].............................
I have this in my form closing event:
For Each FileFound As String In Directory.GetFiles(App_Path() & "tmp", "*.txt")
File.Delete(FileFound)
Application.DoEvents()
Next
For Each FileFound As String In Directory.GetFiles(App_Path() & "tmp", "*.txt")
File.Delete(FileFound)
Next
I used to run through an ultragrid with a for each loop and that took forever, I stumbled accross this way and it's much faster but I noticed today I still have some straggling .txt files after the form closes at times. Is there a way to actually verify all the files have been deleted before closing the form?
I ran the same for each loop twice to work it out but not sure if that works or worsens it. Also, I'm not entirely sure what that application.doevents does as I initially thought it would finish all above lines before continuing but that does not seem the case. Anyway, these .txt files files are about 500KB and up to 1000 of them at any one time so it's not instant but it's still pretty fast, faster then looping through a grid.
I want to make a very simple program that remove duplicate domain name from a txt file. First, it must have a Open file Button so that it can load list of url to Listbox.
So, the URLs will be loaded into listbox. Then It has 2 more button Start and Save button Lastly one counter to calculate how many URL in that listbox
So example.. let say I have a txt file which contains URLs
[URL]
I open this txt file and loaded it into listbox (can scroll)
Then when I press start button, it will delete the URL that has same domain name. so the output will look like this
[URL]
Then I can save the URL from listbox to my disc drive as text file
Is there a way to detect if a file is being deleted,
1) Using the Del key
2) Using the Shift+Del keys
3) Using the above keys from a remote computer through a shared folder
And instead of deleting move it to another folder in the same computer. Basically when a user tries to delete a file or folder it should move it to a specified folder instead of deleting it.
I need to execute the following commands from my application:
Echo Y | DEL C:Folder1cache*.*
DEL C:Folder1file.abc
DEL C:Folder1file.xyz

It seems like it should be pretty simple, I take in a file name as a parameter, create a new name for it, delete it, then try to copy it back from an older version of the same file, and update the connection string. However, it continually tells me that "The file 'filenamehere' already exists." If I set overwrite to true then it goes through just fine, except it doesn't actually copy the file. Obviously I also check the folder, and the file does in fact Not exist...I've also checked all the file paths and what-not, they are all accurate.

My application runs on a "server" machine and provides files (10megs - 100megs each) to 8 other computers. Currently this is done using a standard shared folder on all 8 computers and the server simply copies the file to \ComputerNameSharedFolder - and everything is great.However, due to new policies we need to remove all shared folders, so using a simple \ComputerNameSharedFolder is no longer feasible. Therefore I need to find a way for my application to be able to share these files in a safe, secure, and compliant way.There has been talk of using sFTP which would require each system to have an sFTP server running at all times (controlled by the application somehow), or also SSL was talked about as it can be integrated into the application easily, etc...

My problem is that I can't set the credentials before I have to assign the variable the value so it throws an error.
I am programming a service for a company that will log valuable performance data on machines that they lease out to other companies. It is critical for them that this information is as safe as possible and that it can only be read by us (a program created by us that is). I already made a trippledes encryptor that works fine but i still have the issue that a person can delete or move or corrupt the file if he somehow manages to get out of the operation software and gain acces to it.So my question is: Can i lockdown a file and make it as good as impossible to change the file or delete it other then by being the admin or the program that is generating them?
View 1 RepliesIm creating a program that stores usernames/passwords for different devices which will require a login to get into the program but I need to save the usernames/passwords somewhere.

View 1 RepliesI have a program that logs into a secure site, looks on the user's home page to find a list of links to reports that can be downloaded and then selects each one - this is currently a manual process but with 100 reports a time it takes a while. The idea is that all the reports will download to a specified folder with generic names so the user can play with them on their own computer rather than having to search through them online.
Anyway, everything's gone well as far as using a WebBrowser to connect to the site, log in and get the list of URLs however it falls down when it tries to link to them. I have tried two methods:
1 - Navigating straight to the URL, this gives an error message every time (asking me to try again)
2 - Directly downloading the URL with a WebRequest class (below) however this doesn't download the actual file, but rather a copy of the login page.

I am writing a program that acceses a file in VB/Visual Studio 2008 on Win7 and running it as a user who has admin credentials. I am opening the file with the following code:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None) To test to make sure I can't access this file, I tried to open it with Notepad and I was able to and got no errors. I wrote a new value using Notepad and even saved it and I didn't get any errors form Notepad or my VB program.
I then went on and treid to open the same file twice from my VB program as:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None)
Dim Input2 As New FileStream("C:FileTest est.txt", FileMode., FileAccess.Read, FileShare.None)
And I receivded an error in my VB program as expected. So the FileShare.None switch kind of works. Although I was still able to open the file with Notepad while my VB program had it open. I was aslo able to open Windows Explorer and reame it and even delte it while my VB program had it "open", in the write mode no less without my VB program knowing anything about it.
Why are other applications able to ignore the FileShare.None switch? Seems pretty useless if that's the case. And a huge secruity problem

I am making an program that stores most of my text files in it. So I need a secure password protection to protect my information's.
