WindowsPrincipal object gives null value for username when checked in component

Hi,

WindowsPrincipal object gives null value when checked in component .It throws me a exception "unable to cast object of type "system.security.principal.genericprincipal to type system.security.principal.windowsprincipal " where as if the same code is used in winforms I get the current windows username correctly.The one line code that I use is,
" WindowsPrincipal user = (WindowsPrincipal)System.Threading.Thread.CurrentPrincipal;"

does that mean that current thread of the windows application has different authentication than its own components.

Iam confused ..!!any help..

Regards,
Naveen

Have a look at this[^] article on Fusion. Fusion provides you with information on the GAC (as well as other assembly locations).

Error while using System.Net.Mail.SmtpClient to send mail

I am trying to send a mail through my console application which is in .Net 2.0 with C# language. I am using the class System.Net.Mail.SmtpClient to send a mail. This was decided because the older version of this class System.Web.Mail.SmtpMail is now totally obsolete.
But I get an error message as "Failure sending mail." when I run my code.
I tried to resolve this by following:
1. Tried pinging the address from command prompt. It shows reply.
2. Assigned port number as number 25. Doesn't work. Gives same error.
Following is my code

FromEmail = "anil.soman@xyz.com";
strEmailAddre = "somebody@xyz.com";
strSubject = "some subject";
strBody = "some text for body";
System.Net.Mail.SmtpClient SMTPClient = new System.Net.Mail.SmtpClient();
SMTPClient.Host = "smtpservername";
SMTPClient.Port = 25;
SMTPClient.Send(FromEmail, strEmailAddre, strSubject, strBody);

What could be the reason for this? Any suggessions? Thanks in advance.

Regards,
Anil

1) Create an MailMessage object. I know it's the same thing but...you can give it a try.
2) Check the port number, because usually it's 25 but it can differ from one server to another
3) Try configuring an email client like Outlook and if that doesn't also work....it's from somewhere else than your App

Hope it helps.

Thanks for your suggessions karkster. Unfortunately it's not working.
I came to know that the code is not working because my local machine does not have SMTP server installed on it. So I need to run the code on a machine where it is installed already. Will try for this.

Handling Text data taken from file

Hello,

I'm doing some free-time programming with learning objective (in c#), and one of my "projects" led me to separate data taken from a text file.
Opening and retrieving data is no problem, I just put it into a ArrayList of string element for now. But when I want to separate the data from that ArrayList, the only solution I've come up with is as 'ugly' as this one:

ArrayList stream = new ArrayList();
(some code here)
foreach (string str in stream)
{
if (str.contains(some string))
{
do something
}
else
{
if (str.contains(some other string))
{
do other thing
}
else
{
(... even more if's)
}
}
}

I think there should be another way to do this, specially without so much "contains" operations that are time consuming.
Can you give me some directions on how to break such items apart?
I'm thinking this could also be used in other areas like socket communication.

This feels like a very dumb question to me, but if I don't ask, I'll never learn.

Thanks for any help you can give me.

Try using a List<string> template instead of an ArrayList. This class has a FindAll method that you could find to be helpful.

Hope it helps.

It's a good sugestion, especially with the use of a "Predicate" in the search field.
However, now I've got a new question... Wink | ;)

Is it possible with .net 2.0 to get a range of data between known delimiters using predicate's? This would be soooo much cleaner.

Thanks for the hint.

I don't want to be rude, but take a look in Visual Studio's Help - MSDN, you'll get most of your answers there.

I suppose you have seen that the FindAll method retuns a List<list>, so you can call the list's GetRange method...;)...would that help?

variable as type of generic (method)

7-Oct-07 22:50

Hi!
so i've got this generic method:

<br />
UserControl _control;<br />
<br />
public void InitializeSomething<Tclass>(WorkItem workItem) where Tclass : UserControl {<br />
   _control = workItem.Items.AddNew<Tclass>();<br />
}

my goal is to call this method sth like this:

<br />
Type someType = typeof(someOtherObject);<br />
someObj.InitializeSomething<someType>(WorkItem);<br />

but this of course won't work..
my question is: is it possible to pass variable containing some type as Tclass for generic?!

thanks for any help!!!

I don't really get what you're aiming for... Doe you want to create a collection of controls which are derived from some kind of type?

mmh..
well, for example List<>.. inside the <> you have to put class name.. and my aim is to pass this class name through some variable.

You can't specify the type for generics with a variable. The point with generics is that the type is known at compile time so that the compiler can generate the code for the created generic type.

In this way you compare the instances of the 2 objects. If you want to compare 2 arrays you have to compare each element within those arrays

private bool AreEqual(byte[] a, byte[] b)
{
 if (a.Length != b.Length)
  return false;
 for (int i = 0 ; i < a.Length ; i++)
  if (a[i] != b[i])
    return false;
 return true;
}

Hope it helps.

No. You are trying to return an array of StoredProcedureInformation objects but the return value of your method is defined as a single instance of a StoredProcedureInformation object. You should change your code to:

public StoredProcedureInformation[] ReturnStoredProcedureInformation(int length)
{
StoredProcedureInformation[] sp = new StoredProcedureInformation[length];
return sp;
}
