This site contains many articles about WMI, look inside and you will find many good one.

Their should probably be a registry hive somewhere that stores the add/remove list of programs installed on the machine, I can't really help with the System.Management namespace though.

I just started C# 2 weeks ago and I'm loving it.
One simple question.
btnStart.Text = "&Start";
What is the purpose of the &.
Thank you to the forum, you guys / gals are great.

Normally you use the "&" when naming menu items. If you run your program the character preceded by the ampersand is underlined in every menu item and you can "simulate" clicking the menu item by pressing the respective character whilst holding Alt. So it allows users to access the menu without using the mouse.

If you use &Start, then if you press Alt, the "S" will be underlined.

Hey!
I have a Usercontrol that contains several controls. There is onlye one of these controls that may ba focused by using tab(tab index = 1 and tabstop = true). The other controls in this usercontrol have index = 0 and tabstop = false.
On the mouse over event on this focusable control i se the control to focus(ex this.txtBox.Focus();) and this works fine.
But when i try to use Tab to leave the usercontrol there simes like another control get focused and I have to press tab twice to leave the usercontrol.
Any ide how to lose the focus/activ of the usercontrol on TAB? I want the next usercontrol or regular control to become focused on one TAB press.

Hi friends,
I am facing a PROBLEM WHILE I send mails with the SMTP class of System.Net.Mail.
The code shows below.
MailMessage mail = new MailMessage();
//set the addresses
mail.From = new MailAddress("from@domain.com");
mail.To.Add("to@domain.com");
//set the content
mail.Subject = "This is an email";
mail.Body = "this is the body content of the email.";
//send the message
SmtpClient smtp = new SmtpClient("mysmtpserver.net");
//to authenticate we set the username and password properites on the SmtpClient
smtp.Credentials = new System.Net.NetworkCredential("user@domain.com", "password");
smtp.Send(mail);
I have a valid smtp server name, username and password. I configured it to outlook and working fine. And wen I test it using telnet port 25 then also its working.
I upload the file to my hosting space. I have two hosting account with godaddy.
The mailing script is working fine in one hosting account. That hosting account have SSL and dedicated IP address.
But the mailing code is not working in the other hosting account. That hosting account is Windows hosting + ASP.NET 2.0 supported.
The error I am getting is as shown as below.
System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpTransport.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message) at _Default.Button1_Click(Object sender, EventArgs e)

I am writing an simple application that will delete a file/directory. The application recives the target file as an argument. I have also put a shortcut in the W Explorer contextual menu, via Shell registry subkey of the folder entry
in the HKEY_CLASSES_ROOT.
[HKEY_CLASSES_ROOT\Folder\shell\NewMenuOption]
@="Wipe it ..."
[HKEY_CLASSES_ROOT\Folder\shell\NewMenuOption\command]
@="D:\\FileWiper\\bin\\Debug\\FileWiper.exe \"%1\""
If a launch the program from a shell with an filename/folder as an argument it does it's job.
But if the program is launched via the option in the Explorer menu and the selected targer is a folder (with a simple file it works), then the deleting fails with the exception " ... file being used by another process". It seems that the program keeps an open handle on the directory. The delete operation is made via Directory.Delete() ( tried also working with DirectoryInfo ...same result).
Any one has any idea how can I get past this ?
------------------------------------------------------------------
LATER EDIT : I managed to track the problem after all. Simple stuff really, but forgot about it. Windows set the current directory for the program was set to be the target directory, so a simple change of the current directory was enough to get the program going.

Do you have any Yahoo toolbar. It comes with a popup blocker. There may be any other toolbar that might be having a popup blocker. Check that and disable it.

I am trying to create an application that simply starts listening on a specific port number on the local machine, and writes all data received to a text box on the form. There will be a 3rd party application that is sending data th my IP address on a specific port number.
From what ive been reading, maybe I should use a TCPListener but Im not sure where to start.
Any help would be appreciated.
Thanks.

Hi shanthi,
You can find classes to work with Active Directory on System.Directory Services namespace. Please dig in to msdn which will help you do this.
If time allows i will create some working code to do this.

I am not sure if you have function to do this in .net how ever following WMI class will help you.
using System.Management;
.
.
.
public void GetOsDetails_Win32_Account()
{
ObjectQuery queryObject = new ObjectQuery("select * from Win32_Account");
ManagementObjectSearcher searchObj = new ManagementObjectSearcher(queryObject);
ManagementObjectCollection collection = searchObj.Get();
foreach(ManagementObject obj in collection)
{
Console.WriteLine("Caption:"+obj["Caption"]+
"\n"+"Domain:"+obj["Domain"]+
"\n"+"NAME:"+obj["Name"]+
"\n"+"LocalAccount ?:"+obj["LocalAccount"]+
"Status:"+obj["Status"]+"\n");
}
}
more values on this class are availe on

Hi Rahul,
Please try changing the query in the earlier code ie
select * from Win32_Accounts to select * from Win32_Group where name = "Administrator".
This will provide you with all the users in the admin group.The class Win32_Group is a inherited from Win32_accounts.
I have not tested this code but theoretically it should do the purpose.
Please let me know if it works.
