I have read the initial post and the replies of the thread. I would like to say, just as a piece of advise, if you are about to post here each and every compile error you get without even reading it in order to get your code working, you will need at least one month to develop the "Hello world" application. This compile error is telling you that "Program ... has more than one entry point defined". Just this[^] would have solved your problem.

I wrote a thread to capture the fingerprint image continuously from the biometric device but while stopping it will be getting very slow to stop it

Any boby help me to capture an finger print continuously from the biometric device. There is no function in sdk to capture the continuously
|
|
|
|
|
I find that very hard to believe. Otherwise the user has no way of determining if the print is centered in the device or not. There has to be some function in the SDK to do this.

p.s: it's my first time I do server/client in c#/
Need help. Thanks.

Without further information it will be difficult for anyone to help you except in the most general terms.

I don't know what info do you need.
I've opened two different form Application projects one is server the other is client.
When I hit "Run" in order to start server to listen, an error pops up as written in the title.
The reason must be that I don't know exactly how to make run the project correctly, in other words how to run correctly the server and after that the client.
P.S. I did it exactly like I use to do in Java (eclipse), but here it seems to be need to be done differently.

You say "When I hit run" but you do not say if this is the 'Run' button/Menu in VS or something on one of your Forms.
This error occurs when the Framework is unable to find an assembly referenced somewhere in your code. Sometimes due to an explicit call to Assembly.Load or LoadFrom , so do you make any calls like that. More often it is because it cannot find an assembly that is in your 'Usings' section, so are you using any third-party dlls (I say third-party because Framework dlls should be in the GAC and would be found.).
If it is a third-party dll that is causing the problem, this[^], may help.

I mean the 'Run' button/Menu in VS.
I don't use any third-party dlls.
Here is a code of Program class - the server, please tell me what you think:
<pre lang="cs">
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data;
using System.Data.OleDb;
static class Program
{
private static bool listening = false;
private static TcpListener myList;
[STAThread]
static void Main()
{
try
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new ConnectionForm());
IPAddress ipAd = IPAddress.Parse("localhost");
myList = new TcpListener(ipAd, 8001);
listening = true;
}
catch (Exception e)
{
Console.WriteLine("Error..... " + e.StackTrace);
}
while (listening)
{
try
{
Console.WriteLine("The server is running at port 8001...");
Console.WriteLine("The local End point is :" +
myList.LocalEndpoint);
Console.WriteLine("Waiting for a connection.....");
Socket clientSocket = myList.AcceptSocket();
Console.WriteLine("Connection accepted from " + clientSocket.RemoteEndPoint);
new Client_sThresds(clientSocket);
myList.Start();
}
catch (Exception e)
{
Console.WriteLine("Error..... " + e.StackTrace);
myList.Stop();
}
}
}
}

Before I get to your code, you should surround your code with
<pre lang="cs">
your code goes here
...................
</pre>
tags. This will preserve your indentation and uses some syntax colourization, all of which makes it easier to read.
Since your code does not seem to make any use of ConnectionForm and, in fact, places all output to the Console I would try making this a Console Application not a Windows Forms Application. This may not actually cure the problem but will reduce the size of the compiled application considerably, a good thing for a server application.
I can see nothing that is obviously wrong with with your code but you did not include the 'usings' section, which may be where the problem lies.
Most server apps like this have a very limited set of usings, something like:
using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;
If you have more than these then you could also try using the right-click menu to Organize Usings|Remove Unused Usings.

edited it in previous post usings included

OK, now I'm really confused.
Your usings do not include System.Net nor System.Net.Sockets and yet you use, according to your code
private static TcpListener myList;
/pre>
That is not possible.
Either the usings you posted are incorrect or you have edited your code, not pasted it directly.

Sorry my bad , here the true ones:

I have created a project using your code and I cannot get the error that you are getting.
I had to comment out one line as it gave compile errors and I could not find any reference to it despite a thorough internet search.
That line was:
new Client_sThresds(clientSocket);
so it could well be that whatever that is, is the cause of your problem.

It's because you don't have that class.
Just comment that line, and try to run without it.

As I said in my previous post, I did.
I could not get the error that you are getting.
I can only suggest that you copy the entire error message and paste it into the search box on your favourite search engine. It may be that someone else has had the same problem and posted about it.

Hi everyone,
I have developed a desktop application. I have created a menu item to click for backup database from MS SQL Server 2005. This is why I have created a method to perform the operation. But the method is not working well. There’s something wrong in the code which I cannot recognize. Please help me to find the problem and solution as well. The method code is given bellow:
public void BackupDatabase(String databaseName, String destinationPath)
{
try
{
Backup sqlBackup = new Backup();
sqlBackup.Action = BackupActionType.Database;
sqlBackup.BackupSetDescription = "ArchiveDataBase:" + DateTime.Now.ToShortDateString();
sqlBackup.BackupSetName = "Archive";
sqlBackup.Database = databaseName;
BackupDeviceItem deviceItem = new BackupDeviceItem(destinationPath, DeviceType.File);
SqlConnection sqlCon = new SqlConnection(GenericDataAccess.GetConnectionString());
ServerConnection connection = new ServerConnection(sqlCon);
Server sqlServer = new Server(connection);
Database db = sqlServer.Databases[databaseName];
sqlServer.Databases.Add(db);
sqlBackup.Initialize = true;
sqlBackup.Checksum = true;
sqlBackup.ContinueAfterError = true;
sqlBackup.Devices.Add(deviceItem);
sqlBackup.Incremental = false;
sqlBackup.ExpirationDate = DateTime.Now.AddDays(3);
sqlBackup.LogTruncation = BackupTruncateLogType.Truncate;
sqlBackup.FormatMedia = false;
sqlBackup.SqlBackup(sqlServer);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n" + ex.StackTrace);
}
}
And the click event from where I am calling the method is also given:
private void backupMnuItem_Click(object sender, EventArgs e)
{
BackupData_Bl backup = new BackupData_Bl();
backup.BackupDatabase("CFM", "D:\\TEMP");
}
For your information (it might help you to find the problem) I have first create my database using SQL Server Management Studio. Then I’ve move the database from sql server installation location to my project directory under a folder named DB. After that I have attached the database using SQL Server Management Studio.

I am working in c# i want to apply the timer on the buttons or want to change their colour randomly from green to red after certain time.I dont want all the buttons to change the color from green to red at the same time i.e if there are three buttons then then they can change colour from green to red at different time periods. Is there any function to do this???

Subclass Button and wrap a Timer exposing the properties and methods of it that you need.
Something like this - just set ColorA , ColorB and Interval then call Start .
using System;
using System.Drawing;
using System.Windows.Forms;
public class ColoredButton : Button
{
public static readonly Color DefaultColorA = Color.Red;
public static readonly Color DefaultColorB = Color.Green;
public const int DefaultInterval = 1000;
public event EventHandler Tick;
private Color colorA;
private Color colorB;
private Timer timer;
public ColoredButton()
{
colorA = DefaultColorA;
colorB = DefaultColorB;
BackColor = colorA;
timer = new Timer();
timer.Interval = DefaultInterval;
timer.Tick += TimerTick;
}
public Color ColorA
{
get { return colorA; }
set { colorA = value; }
}
public Color ColorB
{
get { return colorB; }
set { colorB = value; }
}
public int Interval
{
get
{
if (timer != null)
return timer.Interval;
else
return DefaultInterval;
}
set
{
if (timer != null)
timer.Interval = value;
}
}
protected override void Dispose(bool disposing)
{
if (disposing && timer != null)
{
timer.Dispose();
timer = null;
}
base.Dispose(disposing);
}
protected virtual void OnTick(EventArgs e)
{
EventHandler eh = Tick;
if (eh != null)
eh(this, e);
}
public void Start()
{
if (timer != null)
timer.Start();
}
public void Stop()
{
if (timer != null)
timer.Stop();
}
private void TimerTick(object sender, EventArgs e)
{
if (BackColor == colorA)
BackColor = colorB;
else
BackColor = colorA;
OnTick(EventArgs.Empty);
}
}
