hello to all
I am writing an ivr program that uses kdtele component. also i use dialogic cards with version 5 that support tapi.
i have problem when the user end the connection (remote disconnect).
and i can't find if the connection still connected.
i use c# for the program so i write it here.
how can i tell that the user disconnect the handset or hangup.
i use many ways but no success
thanks for reply beforehand.

Never heard of it.
Your best source of information is going to be KAED Systems[^].
It's extremely unlikely anyone that has any experience with the library is going to see your post. When you have questions about 3rd party libraries, he best source of support for those libraries is the vendor who created them.

1. You should use <pre> or <code> tag to format code properly.
2. You should debug your application and try find the problem yourself. You just wrote some code, it doesn't work, so you think someone on the internet will fix it for you?
3. Connected to number 2 - you should tell us more specifically, what the problem is. "application hang" in the subject isn't telling us to much. You think we will run your code and check, where does it hang? We won't. Firstly you only gave us part of the code ("code-behind" of your form), and we don't know what controls you have on this form. Secondly, it's your job to locate the problem, and then we can tell you how to fix it. And if you can't locate the problem, than you should find at least a piece of code, that's causing it. Most of us here are willing to help, but you should show us, that you've done something to solve the problem yourself.
Don't forget to rate answer, that helped you. It will allow other people find their answers faster.

I tried to get the connected users by Win32_serverConnection/Win32_ServerSession
but I found out that WMI class is unable to get those users connected to my site
I only captured users connected to my computer by mstsc
Can anybody out there give me a clue?
any help would be greatly appreciated!

On your second point, if you got the code from an article, then there is a "new message" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

I tried to do it myself, but I found out
that method can't work on my own,
thus I found a smiliar tool over here.
but I found out that it still can't work as well,
so I don't really know what's wrong with it.
is there something related to my OS?
I'm using Windows XP SP3

As I said: if you got this from an article, then the author of the article is the best person to help you.

Thanks for your suggestions,
I can't find that ariticle anymore..
maybe the best thing I should do right now is to wait
somebody can help me with that.

I cannot help with your first problem: I don't currently have any computers connected to mine, and am not about to set up a connection just for a quick test! Someone else will be along soon, who can help more with that part of your question.

another question,
by which way others access to my computer,
the info will be record?
like FTP, or access to the site?

Hello there.
I'm learning generics and linked list.
now i have managed to make a generic linked list, but I don't know how I can get the needed data out of it.
I can do it without generics, but with generics I don't know how, I can't find it.
So here I add people and show all the added people.
LinkedList<Persoon> LlPersoon = LinkedList<Persoon>.GetInstance();
LlPerson.Add(new Persoon(1, "First Person"));
LlPerson.Add(new Persoon(2, "Second Person"));
LlPerson.Add(new Persoon(3, "third person"));
Console.WriteLine(LlPerson);
Console.WriteLine(" Done. Adding Persons...");
but how can I just show the second person?
Without generics I did the following thing to get the name of person 2
public string getName(int iPersonNr)
{
Person Per = FirstPer;
bool bln = false;
string strName = "N/A";
while (Per != null && !bln)
{
if (iPersonNr == Per.getNumber())
{
strName = Per.getName();
bln=true;
}
Per = Per.getVolgende();
}
return strName;
}
I tried for days, but can't find it.
It must be something simple but I have no clue as I don't master generics enough.
any directions or help would be appreciated
thx

Are you asking about your own implementation of LinkedList? There is one available in .NET since 2.0
This would be an example of its use:
public class CPTest_LinkedList : CPTest {
public override void Test(int arg) {
LinkedList<Person> persons=new LinkedList<Person>();
foreach(string s in new string[]{"jef", "jan", "jos"}) persons.AddLast(new Person(s));
foreach(Person p in persons) log(p.Name);
foreach(Person p in persons) if (p.ID==1) log("person 1 = "+p.Name);
}
public class Person {
public string Name;
public int ID;
public static int count=0;
public Person(string name) { Name=name; ID=count++; }
}
}
which outputs:
18:57:36.439 CPTest.log-59 jef
18:57:36.453 CPTest.log-59 jan
18:57:36.467 CPTest.log-59 jos
18:57:36.479 CPTest.log-59 person 1 = jan
Its use is pretty easy as it implements ICollection. The one thing you can't do with such LinkedList is indexing, as in persons[1] which works fine in array-based collections such as List<T> itself. Indexing in LinkedList requires scanning the list one node at a time.

Lists are for putting things in, not getting things out.

Best implemented in WOM. See a datasheet here[^]

I recall seeing that data sheet when it originated, a very long time ago...

I usually use a soft /dev/null for storing, but thinking about it, it might be better having it hardware accelerated. I will have to do some benchmarking...

Person secondPerson = LlPerson.First.Next.Value;
The above code assumes you are using the built-in linked list. LinkedList doesn't have a "GetInstance()" static method, as you seem to be using in your example. With the .Net LinkedList, you'd initialize it this way:
LinkedList<Person> llPerson = new LinkedList<Person>();
