The problem isn't that noone knows how to solve the problem. It's that you're not listening or understanding the explanation of why your code isn't working.
You created a new RASCONN object, then set one of it's properties to IntPtr.Zero, then you retrieved that very same IntPtr.Zero from the property and passed it as a parameter to RasHangUp. What you passed was not a valid handle to an existing connection. You just made up your own handle that doesn't have any meaning and tried to get RadHangUp to disconnect it. It can't disconnect a handle that doesn't represent a valid connection.
Let me rewrite your code to show you what you did:
try
{
RAS.RasHangUp(IntPtr.Zero);
}
RasHangUp returns a value which you are ignoring. API calls like this will NOT throw an exception because they know nothing of the .NET Framework. If you read the documentation on RasHangUp, you'll see that it returns 0 if the call is successful, or a non-zero value if it fails. This non-zero value is the error code.
What you should be doing to get the code is:
int rc;
rc = RAS.RasHangUp(validHandle);
if (rc != 0)
{
}
else
{
}

IT WORKS!! thanks a million Dave!! I'm listing it here for anyone sick of RAS
RASCONN lprasConn = new RASCONN();
lprasConn.hrasconn = IntPtr.Zero;
int lpcb = 0, lpcConnections = 0;
lpcb = Marshal.SizeOf(typeof(RASCONN));
RAS.RasEnumConnections(ref lprasConn, ref lpcb, ref lpcConnections);
RAS.RasGetConnectionStatistics(lprasConn.hrasconn, stats);
IntPtr m_ConnectedRasHandle;
m_ConnectedRasHandle = lprasConn.hrasconn;
MessageBox.Show(Convert.ToString(RAS.RasHangUp(m_ConnectedRasHandle)));
Thanks again Dave

Hello,
Does anybody know what is new in .Net 3.0 related to file archiving methods?
If nothing new, what classes from .Net 2.0 are recomanded in doing this task?
Thanks,
Lukas

".NET 3.0" is a stupid Microsoft marketing name. Absolutely nothing has changed in the CLR, WinForms or ASP.NET from 2.0 - it's exactly the same binaries. The only new stuff is in WPF, WCF, Workflow Foundation and ObjectSpaces.

What do you mean by archiving? You mean adding files to a zip or rar file?

Hello, again!
By Archiving I mean adding files\directories to a zip or rar file.
Thamk you for your interest!

Thamk you f
Lukas, you have a number of options: the System.IO.Compression APIs[^] in the .NET framework v2. You can use the free and open source #ZipLib[^]. You can also use the J# runtime zip libraries[^]. I recommend using the #ZipLib -- I've heard about some nasty bugs in the System.IO.Compression APIs, and the J# zip libraries forces a dependency on the J# libraries, which aren't installed by default on most .NET setups (including the default Windows Vista install). So, I recommend #ZipLib.

Hello My application is often launched while the user is logged on via Remote Desktop Connection. My question is-is there any way for my application to determine if it is being launched in this way. Because of Directory permissions my application writes configuration files to the hard drive. Alot of the people that log in via Remote desktop connection do not have rights to the directory, this is the scenario and the customers IT dep. does not want to change it. So I will be able to open the app in readonly mode if it is launched via RDC Connection. Do you know how to do this or can you point me in the right direction.
BTW the config files are written to the user Docs & Settings\user folder\application data\Our Company\Configuration file. I am using .Net 2003 C# of course.
Thanks in advance for any information.

There is no difference between a user logging in over Remote Desktop and the same user logging in at the console (i.e. at the physical keyboard). You should work out whether the file you intend to write is writable, which you should do simply by trying to open it for writing. Ensure that you don't accidentally truncate it in the process!

I can assure you that I do not need Beginner Tutorials, thanks for the insult though. My suggestion is that if you do not have anything pertinent to say, please quit trolling.

Yes, but isn't it the schools job to teach you? 
Just start with some beginner tutorials. Visual Studio is quite important, and you can use the object browser to learn a lot about objects/classes, etc... Just do some research, I wouldn't know where to start, and I really don't have the time either. Goodluck

Either something is wrong with the CP message board, or you modified your posts. Proof of this might be that the reply you can read above, makes absolutely no sense anymore.
When I read your original post, "programming in c#", it just said "Are there any C# tutorials?" in your post. And thus I replied with giving you a link to c# tutorials. I can't really see how this is at all insulting, on the contrary, at the moment I feel insulted by your reply.
I'm sorry you were offended, although I don't feel I should apologise

Also... checking the emails I got, the post was originally made by a user called 'babyhannah', and she/he replied this to my google link:
thanks for replying..actually, i hav a project in our class...were supposed to do a game using c#...the game is a maze...and im not really familiar on the methods or functions in c#...wt im supposed to do is to let my player move from the starting point to the finish point..and im not xur how to put my algorithm into the "C# language"...do u hv ny idea?
can anyone tell me what's going on?

Well Sorry, after reading your reply[Modified] it seems as though the site may have crossed a couple of posts.

Hi,
I'm adding TreeView nodes in the following way:
<br />
foreach (System.IO.DirectoryInfo di in dirs) {<br />
inTreeNode.Nodes.Add(new TreeNode(di.Name));<br />
<br />
...<br />
}<br />
But now i want to put custom icon, so i added a ImageList and i searched for the overloaded method which permits me to select the icon index:
<br />
inTreeNode.Nodes.Add(new TreeNode(di.Name));<br />
inTreeNode.Nodes.Add(di.Name, di.Name, this.folderIndex);<br />
The thing is that the overloaded method doesnt accept a TreeNode as parameter, so i have first created the node and then made the association with the image index i want.
This didnt worked as now i have two copies of the same node with different icons. How can i solve this?
Thx,
Nuno

it clearly _does_ accept TreeNode as a paramter.
try this:
TreeNode tn = new TreeNode(di.name);<br />
tn.ImageIndex = ...;<br />
inTreeNode.Nodes.Add(tn);

I was just exploring that option!!
I now discovered other problem.
When i select a item in the tree, it stays with the first image list index, even when i have already defined a index for it. Is this normal?
Thx for your help in the other thread, the treeview its working!

No problem and I'd like to continue to help you, but I don't understand the problem. Can you rephrase it, maybe with some code samples?
public object BufferOverFlow<br />
{<br />
__get { return BufferOverFlow; }<br />
__set { BufferOverFlow = value; }<br />
}

I cant show code sample for this problem.
When i run up, everything is fine. The tree is filled up and the file types which have a special icon are set up.
However, when i select an item in the tree, the icon changes to other icon, in this case, the first icon i have in my image list.
Was i clear now?
Thx,
Nuno
