VS 2008 Secure Upload Of A File To FTP?
Nov 30, 2009
What 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 making a windows form and through this form i want my users to upload and download files stored in a Directory on a machine running windows 2003.Could anyone please tell me the best and secure way to share files on a directory for users to Upload and download and "without letting the users to know the actual path"..User Clicks on a Button and it will automatically download the files from server.User Clicks on another Button and it will automatically upload the files to server.The file name and paths will be taken from labels which are hidden on my form so the user doesn't need to specify anything..I have 3 Options and looking forward to some expert opinion on this. My main concern is to never reveal the location to users and smooth upload and downloads.Is there any better option..i mean from my windows form perspective only and not talking about firewall settings, folder permissions etc...or any 3rd party software to protect data.[code]

Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1. There is a label on the form. I drag files to this label(its backcolor is black[0,0,0]). What I want is for the filesize to be checked. I already have the uploading to ftpcode, I just want to know if the file is above my limit I set. (250mb per file)

If yes, how to create the server side application

I want to upload a file to a sharepoint document library. This looks extremely easy and trivial but I haven't written any VB in about 10 years, so it's kicking my strASS I have tried looking into using the web services for this, but all of the solutions posted are incomplete, so I've punted and gone after the http put methods. I found this vbscript which works very well, tested on files up to 23MB and it works great.

What I'm trying to do is get the bytes already uploaded. I cannot seem to do this.Another problem: When uploading, the form will not move or change Label1.text. When pbUpload.value == 100, THEN it changes to a different number than label3.text.

I am pretty new at VB but am trying to design an application that will allow a user to select from files on his or her PC, hit a '>>' button, and those files will appear in a list on the right side of the button (so I can then have the application upload those files via ftp). I am planning to use a TreeView control to act as a file explorer in the application. I have been unable to find any resources on the internet to populate the tree view with the user's local file structure, and was wondering if anyone could point me in the right direction.

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...

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?

Im 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. Is there a more secure way to store this than in a text file? Or I could try encryption which could be quite fun.

I 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.
Current Code:
Public Sub DownFile(ByVal sFile As String, ByVal sRemoteUrl As String)
Dim wr As HttpWebRequest
Dim ws As HttpWebResponse

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 have making login system using with php. Now I want to hide the link by using strongest MD5 hash, but the one I have got is uncrackable. I want to decrypt them in the runtime, but I couldn't.
Here's the

Dim md5Obj As New Security.Cryptography.MD5CryptoServiceProvider
Dim bytes() As Byte = System.Text.Encoding.ASCII.GetBytes(strToHash)
bytes = md5Obj.ComputeHash(bytes)
[Code] .....
The GetMD5Hash's method is using for to decrypt the MD5 hash to turns into the actual strings and MD5Hash's method is using for encrypt the strings into md5... However, the connection strings can be sniff the packets sent out. How to decrypt the MD5 hash and how to blocked the connection strings in the packets sent out??

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. I was told that MD5 will get the job done, so I used an MD5 protection to see if it'll be good. I gave the test program to a guy I know and he manage to get my password within a minute. (I am still a bit new to VB so which encryption to use...)

I'm trying to upload a file via FTP from my local computer to an FTP server, which is also on my local computer at the moment. I've got this sub I'm calling:
Public Sub UploadFTPFile(ByVal ftpservername, ByVal fullfilepath, ByVal filename, ByVal username, ByVal password)Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential(username, password)
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile
[Code]...
I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.
