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 1 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()
SmtpServer.Credentials = New _

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 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()?

View 6 RepliesI have a vb.net web application running on a local server with IIS6 installed. I was using Integrated Windows authentication for allowing uses to access the data in the application which is a combination of flat files on a local directory and db information. That worked great until another dataset was brought online and incorperated into the existing application. The problem is the flatfiles for the second dataset are stored on another server. So, although user could see the file files in the application window, if they attempted to open one it would say access denied on the directory.
I explained this to our network administrator who explained the users didn't have access to that server (even though both servers had the same permissions) and that the application wouldn't work. The only way in which I got it to work was I had to
Enable Anonymous access and use a windows user account for that access, which works. However, the application requires the users NT account for various reasons. How can I get this to work with Integrated Windows Authentication?
When I try to use Windows auth, the pop-up tells me: X website required login for Y domain.How can I hide the website name? And only show "You are required to login first" text on that pop-up?
