Download From FTP Server WITH Credentials?
Jun 10, 2012I want to download my update files for my program from an FTP server, but i need to login first with the credentials. I have tried many things, used some examples on MSDN, googled a lot, but i can't find the code that i'm looking for... I also use a DLL of someone that i've imported into my project. I don't know if that harms my part of being unable to log in.
I have ZERO experience with FTP servers or Network Credentials, i've learned the little things about it on google.

Email Credentials Are Showing Up?
Jan 6, 2012I have a routine that sends an email via SMTP. I'm using googles smtp server - "smtp.gmail.com". I'm using my gmail email address/password as the authentication credentials. My webpage form consists of the following fields:
"User's Name"
"Organization"
"User's Email Address"
"Subject"
"Memo"
In testing this functionality, I've found that my problem is that when the email is sent, it uses my authentication email address (my gmail email) instead of the "User's Email Address". If I can't see the User's email address, this functionality is useless.
Here is my code below.
Private Sub FormatEmail()
Dim Email_Sent As Boolean = False
Dim toEmail As String = "blakemc@mail.com"

Asp.net - Including Login Credentials With A WebRequest?
Jul 7, 2010I am trying to "behind the scenes" log myself into a website, from the VB code behind my ASP.NET website. But I am dumbfounded as to how to do this.

I want to click a button on my website and have its Click event send a username and password to another website. This other site isot affiliated with mine. I realize the concept may seem stupid, but I plan on taking this further later, but Just need to know this now.

Nov 15, 2009I am trying to readwrite to a UNC share from a machine that is not on the corporate domain. I'm performing a mkdir(UNCpath) command and I'm also writting by using an xml.save(UNCPath) command.
The problem is that users who are not on the domain are getting permission errors when attempting to access the unc share.
Is there a way to pass credentials automatically when attempting to access the UNC share.
I've read a bunch of posts and people have suggested mapping a network drive then writting but I would only like to do this as a last resort.

.Net - Open Remote Shared Folder With Credentials?
Sep 26, 2011I need to open a folder on a remote server with different credentials in a window (explorer.exe).I managed to do it with no credentials (my credentials), but when I do it with another username and another password than mine, it opens a prompt to enter a username and a password, and it says "access denied".
In the access log on the remote desktop, it says that I tried to connect with my own username, and not the other username I entered. So, the process obviously did not work.

ASP.Net (IIS 7.5) Querying Active Directory Without User Credentials?
Dec 20, 2011I have multiple web applications that I've built for our intranet. I wanted to allow users to not worry about logging in, so these apps pull the currently logged on user when they hit the site. I used this code for this to happen:
Dim userName As String = User.Identity.Name
CurrentUser = userName.Substring(userName.IndexOf("") + 1)
This works like a charm, no issues here. The next step is to query Active Directory for that logged in user to pull various information. How I currently have it coded, it works like a charm on the devleopment side (typical because I'm not running IIS).The problem becomes when I publish it to my IIS server (Windows Server 2008 R2 running IIS 7.5), I get error messages that point to the specific line in my code that queries Active Directory. The interesting part is these apps were working great last week. They broke after my server admin did the latest batch of Windows Updates (please note, I am running them using .Net Framework 4.0)Before I had each app setup so that Windows Authentication was Enabled, the other Authentication types were disabled. For providers, Negotiate is #1, NTLM is #2. For Advanced Settings, Extended Protection = Off, and Enable Kernel-mode authentication is checked.

In doing this I also removed the string that was higher up in my web.config section. This did not work either (fyi, this was a great reference[url]I then tripped across this article: [url] which seemed to be a similar situation. This article eventually referenced "Double Hops", after looking into this and trying a few things, this didn't solve my issue either.Next StepI am going to try a new IIS 7.5 implementation on a different Server 2008 R2 system and essentially start from scratch, to see if the problem recreates or not.
Asp.net - Send HTTP Authentication Credentials To A Non .NET WebService?
Sep 3, 2009i'm doing everything by the book, but the .NET client is simply not sending an authentication header when making requests to my (PHP) SOAP Web Service. I have verified this by logging the raw post data at the PHP end of things and .NET never sends any auth headers.This is the code I am running before making calls on my ExampleWebService Web Service:
ExampleWebService.PreAuthenticate = true;
NetworkCredential myCred = new NetworkCredential("myusername","mypassword");
CredentialCache myCache = new CredentialCache();
[code]....
As I understand it, PreAuthenticate should force the sending of my HTTP Basic Auth Credentials on every request regardless of challenge. Does this only work with IIS hosted services?
