if i wouldnt read that msdn or google i wouldnt ask here ,
in the msdn they only show examples of
Thred t = new thread(ThreadStart(target));
if you read my question i need something a bit different , dont know if its possible thats why im asking.

beleive me, a lot of people do NOT consult MSDN or Google before asking, you are the (positive) exception here.
But to answer your question - No, you do not need anything different.
Where you have written "//Some code i dont know how to implement" the code (pseudo code, I am not sure delegate names and signatures match - find them in MSDN) is as follows:
<br />
ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadMethod));<br />
}
<br />
private void ThreadMethod()
{<br />
}<br />
Depoending on how much control you want with the thread, you can use one of the alternatives (create a Thread object etc) instead of the ThreadPool.
If you REALLY want it in the same method you can replace the "new WaitCallback(ThreadMethod)" part with an anonymous delegate. But I really recommend you try to think of starting threads as follows:
1) The creating thread continues execution in the current method
2) The new thread starts running in a new method/scope.
it will help you later on as this is how the thread methods are designed - and how they are used by most developers.

The anonymous delegate did the trick ,
Thanks
i did something like that if that's what you mean:
<br />
public void my_multi_threaded_method()<br />
{<br />
Console.WriteLine("calling thread");<br />
<br />
Thread t = new Thread(ThreadStart(delegate() <br />
{<br />
Console.WriteLine("child thread");<br />
});<br />
t.start<br />
}<br />

plz any ine help me
i need a code for finding whether a file is exisisting in the folder if exist display the file woth some text or not create the file with some text and displaying message that file is created successfully using c#
|
|
|
|
|
you can use System.IO.File.Exists(string path) method to check whether the file exists or not.
good luck
|
|
|
|
|
using System;
using System.IO;
using System.Collections;
public class FileHandling
{
public static void Main(string[] args)
{
foreach(string path in args)
{
if(File.Exists(path))
{
// Your code should run here
}
else if(Directory.Exists(path))
{
//Your code should run here
}
else
{
Console.WriteLine("{0} is not a valid file or directory");
}
}
}
Happy Programming

you must first set the WorkerSupportsCancellation Property of BackgroungWorker instance to true.
then you can cancel it
good luck

You can't just cast your string however to whatever type you want it to be.
I haven't used the function myself, by but reading the documentation it should work like that:
StringCollection coll = new StringCollection();<br />
coll.Add("C:\\Test");
Clipboard.SetFileDropList(coll);

pannel. And the user in the particular group.
Any help or idea is greatly appreciated
Thanks in advance

you can do that using WMI through System.Management namespace (you must add it as reference)
you can query Win32_UserAccount and Win32_UserGroup from WMI for collecting your data
maybe this is not the best solution but it's going to work
here is the code
public class UserManagements
{
public class GroupUser
{
const string PATTERNNAME = ".*Name=\"(?'name'.*)\".*";
const string PATTERNDOMAIN = ".*Domain=\"(?'domain'.*)\",.*";
public readonly string groupName;
public readonly string partName;
public readonly string groupDomain;
public readonly string partDomain;
public GroupUser(string groupComponent, string partComponent)
{
this.groupName = Regex.Replace(groupComponent, PATTERNNAME, "${name}");
this.partName = Regex.Replace(partComponent, PATTERNNAME, "${name}");
this.groupDomain = Regex.Replace(groupComponent, PATTERNDOMAIN, "${domain}");
this.partDomain = Regex.Replace(partComponent, PATTERNDOMAIN, "${domain}");
}
}
public class UserAccount
{
public readonly int AccountType;
public readonly string Caption;
public readonly string Description;
public readonly bool Disabled;
public readonly string Domain;
public readonly string FullName;
public readonly bool LocalAccount;
public readonly bool Lockout;
public readonly string Name;
public readonly bool PasswordChangeable;
public readonly bool PasswordExpires;
public readonly bool PasswordRequired;
public readonly string SID;
public readonly int SIDType;
public readonly string Status;
public UserAccount(ManagementObject userMO)
{
this.AccountType = Convert.ToInt32(userMO.Properties["AccountType"].Value);
this.Caption = userMO.Properties["Caption"].Value as string;
this.Description = userMO.Properties["Description"].Value as string;
this.Disabled = Convert.ToBoolean(userMO.Properties["AccountType"].Value);
this.Domain = userMO.Properties["Domain"].Value as string;
this.FullName = userMO.Properties["FullName"].Value as string;
this.LocalAccount = Convert.ToBoolean(userMO.Properties["LocalAccount"].Value);
this.Lockout = Convert.ToBoolean(userMO.Properties["Lockout"].Value);
this.Name = userMO.Properties["Name"].Value as string;
this.PasswordChangeable = Convert.ToBoolean(userMO.Properties["PasswordChangeable"].Value);
this.PasswordExpires = Convert.ToBoolean(userMO.Properties["PasswordExpires"].Value);
this.PasswordRequired = Convert.ToBoolean(userMO.Properties["PasswordRequired"].Value);
this.SID = userMO.Properties["SID"].Value as string;
this.SIDType = Convert.ToInt32(userMO.Properties["SIDType"].Value);
this.Status = userMO.Properties["Status"].Value as string;
}
}
public static GroupUser[] GetGroupUsers()
{
List <GroupUser> groupUsers = new List <GroupUser>();
ManagementObjectSearcher mos = new ManagementObjectSearcher(new SelectQuery("Win32_GroupUser"));
ManagementObjectCollection moc = mos.Get();
foreach (ManagementObject mo in moc)
{
string groupComponent = mo.Properties["GroupComponent"].Value as string;
string partComponent = mo.Properties["PartComponent"].Value as string;
GroupUser gu = new GroupUser(groupComponent, partComponent);
groupUsers.Add(gu);
}
return groupUsers.ToArray();
}
public static UserAccount[] GetUserAccounts()
{
List <UserAccount> userAccounts = new List <UserAccount>();
ManagementObjectSearcher mos = new ManagementObjectSearcher(new SelectQuery("Win32_UserAccount"));
ManagementObjectCollection moc = mos.Get();
foreach (ManagementObject mo in moc)
userAccounts.Add(new UserAccount(mo));
return userAccounts.ToArray();
}
}
you can use it through GetUserGroups and GetUserAccounts methods.
hope the post would be useful

Hi,
I'm trying to select an item in a listbox control by right clicking on it, can you please tell me what's wrong with what I'm doing??
private void listbox1_MouseClick(object sender, MouseEventArgs e)
{
listbox1.SelectedItem = listbox1.GetChildAtPoint(listbox1.PointToClient(e.Location));
}
Thank you guys!

Hi
I suggest to use MouseDown or MouseUp events instead of Click because they give you the mouse button and position all together
and you can find the index of pointed item by using IndexFromPoint method of listBox instance
here is the code I tested to see how it can be done
void listBox1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button != MouseButtons.Right) return;
int index=this.listBox1.IndexFromPoint(e.Location);
if (index == -1) return;
object selectedObj = this.listBox1.Items[index];
this.listBox1.SelectedIndex = index;
MessageBox.Show(selectedObj.ToString());
}
good luck

GREATE
listbox1.SelectedIndex = listbox1.IndexFromPoint(e.Location);
Wish I can give you 6
Thanks a million Hessam!

Error:No connection could be made because the target machine actively refused it
code is given below:
MailMessage message = new MailMessage(emailid, "rajeshvyas2005@yahoo.co.in",
txtsub.Text,txtbdy.Text);
message.Attachments.Add(new Attachment(filupldatchmnt.PostedFile.FileName));
SmtpClient client = new SmtpClient();
client.Host = "80.36.278.159";
client.Port = 4576;
client.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
client.Send(message);
Response.Write("Message sent");

This means your mail server configuraton is wrong.
