View 1 RepliesI have a console application created in VS2005, with a web reference created via WSDL.When I run on my local machine (and I have a browser up) I can access the web service fine (if a browser is not up I get the 407 error).I understand this,since my local client machine MUST go through the company proxy (I assume the proxy is resolved when I sign start the browser).When I copy the application to our server, the 407 proxy authentication required error ALWAYS comes up.The thing is, on the server all check boxes in internet options/connections/lan settings are NOT checked. i.e. the server DOES NOT go through a proxy.I installed wireshark to help track down the problem and it shows that when i access the web service wpad is being called and our proxy server is being called.is there a .net configuration that allows me to say "ignore the proxy".I have already tried variations on the system.net section of the app.config file: [code]It seems that no matter what we do (including changing registry settings) this application ALWAYS tries to go through a proxy.

View 4 RepliesI'm using the following code to send an email from my vb.net web application.
Public Function SendMail(ByVal strTo As String, ByVal strFrom As String, _
ByVal strSubject As String, ByVal strBody As String) As String
Try
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()

It works fine when I use my personal live.co.uk email address as the strFrom value, or even a made-up email address. But when I use a different one (contact@mydomain.com), which is perfectly valid and working, I get the following error:
"The SMTP server requires a secure connection or the client was not authenticated. The server response was: SMTP authentication is required."
This emailing code wont seem to work in my program. I get an exception "The SMTP server requires a secure connection or the client was not authenticated. The server response was 5.5.1 authentication required."

I am using in built sql server 2005 which comes with visual studio 2008 in my project.This is my connection string.SQLConnection oConnection = new SQLConnection("Data Source=.SQLExpress Initial Catalog=Fas");
When I try to open the connection like oConnection.open() I am getting error like "Login failed for this user. User is not associated with trusted connection."By some googling I get the idea that I am using Windows authentication mode. So how can I change it to mix mode authentication? I dont have separate sqlserver installed on my system. It is same that comes with visual studio 2008
I have a program that uses a font that's not stored on many computers, so the font comes with the program, in its resources. Before I was writing to a file and loading the font from that location, but I remember now that sometimes you don't have permission to write to a file. My application will not write to any other files, and having this font available is very important. So, I decided to use Marshal.AllocHGlobal() to store the font in memory, then read it back. (I'm using a PrivateFontCollection object to store these fonts.)Does Marshal.AllocHGlobal() require permissions? Is it more likely that it will throw an exception than IO.File.WriteAllBytes()?

I have used the code from the link below to create a basic login page in front of the Microsoft Live Single Sing On.[url] I managed to combine the two together(LiveSSO w/Forms Authentication) turning off the Integrated Authentication in IIS from the SSO setup.All works as expected if the user successfully authenticates with AD. THE PROBLEM that I am having is that when the user failes to authenticate it only returns: "Error authenticating user. Logon failure: unknown user name or bad password". This message appears also when the user is set to change the password at next logon. What I want it to do is to read the error code of exactly why it failed so I can setup a redirect to a password reset page (i.e. if error is "User flag is set to change pswd" etc.etc.)From the page linked above you can see the VB code of LdapAuthentication.vb which does the trick of authenticating the accounts or returning the error message if the login fails. The part that returns the "Error authenticating user. Logon failure: unknown user name or bad password." Is handled by this subroutine:

That's what I have been trying to customize to see how it can return a specific code based on the user account AD flags, instead of the generic message
