Hi.
I am using thread function in my project. When I close program.exe(form), it is still working at background and in task manager, i can see program.exe still working.
How can I close this program completely?
----------------------------------------------------------- - public void Form1_Load(object sender, EventArgs e)
-
{
-
CheckForIllegalCrossThreadCalls = false;
-
Thread thread_dinleyici = new Thread(new ThreadStart(dinle));
-
thread_dinleyici.Start();
-
}
-
-
public void dinle()
-
{
-
//....
-
while(true)
-
{
-
istemcisoketi = tcp_listener.AcceptSocket();
-
if (istemcisoketi.Connected)
-
{
-
// ...
-
while (rdr_gonderilecek.Read())
-
{
-
gonderilecek_data += rdr_gonderilecek["iletiler"].ToString();
-
}
-
TcpClient tcp_client = new TcpClient(karsi_ip, 30001);
-
ag_akimi = tcp_client.GetStream();
-
akim_yazici = new StreamWriter(ag_akimi);
-
akim_yazici.WriteLine(gonderilecek_data);
-
akim_yazici.Flush();
-
}
-
}
-
}
Because you created the thread inside the Load method, you have no way to reference from other methods. Move the creation outside of any methods to give it Form-Wide scope, so you can reach it from all methods within the form. -
Thread thread_dinleyici = new Thread(new ThreadStart(dinle));
-
-
public void Form1_Load(object sender, EventArgs e)
-
{
-
CheckForIllegalCrossThreadCalls = false;
-
thread_dinleyici.Start();
-
// ...
-
Now in your Form_Closing event handler you can abort the thread. -
public void form1_Closing(object sender, EventArgs e)
-
{
-
thread_dinleyici.Abort();
-
}

Hi,
Firstly thanks for your reply tlhintoq.
I used your codes but I am getting another error;
"A field initializer cannot reference the non-static field, method, or property 'socket_sunucu.Form1.dinle()'" - Thread thread_dinleyici = new Thread(new ThreadStart(dinle));
-
-
public Form1()
-
{
-
InitializeComponent();
-
}
-
-
public void Form1_Load(object sender, EventArgs e)
-
{
-
CheckForIllegalCrossThreadCalls = false;
-
thread_dinleyici.Start();
-
}
-
-
public void dinle()
-
{
-
TcpListener tcp_listener = new TcpListener(30000);
-
tcp_listener.Start();
-
while(true)
-
{
-
-
istemcisoketi = tcp_listener.AcceptSocket();
-
if (istemcisoketi.Connected)
-
{
-
...
-
while (rdr_gonderilecek.Read())
-
{
-
gonderilecek_data += rdr_gonderilecek["iletiler"].ToString();
-
}
-
TcpClient tcp_client = new TcpClient(karsi_ip, 30001);
-
ag_akimi = tcp_client.GetStream();
-
akim_yazici = new StreamWriter(ag_akimi);
-
akim_yazici.WriteLine(gonderilecek_data);
-
akim_yazici.Flush();
-
}
-
-
}
Hi,
I used like this, its getting no error but unfortunately the program still working at background. -
Thread thread_dinleyici;
-
...
-
...
-
-
public void Form1_Closing(object sender, FormClosingEventArgs e)
-
{
-
thread_dinleyici.Abort();
-
}
-
Finally I wrote the line above and its working but is it any side affect for program?
Using Thread.Abort() is not recommended because it can cause crash or data loss sometimes. The recommended approach is to keep a flag for the thread and reset it when the form is closing. I've always used this approach its trial and tested.
Here is modified code: -
# private bool _shutdown = false;
-
# public Form1()
-
# {
-
# InitializeComponent();
-
# }
-
#
-
# public void Form1_Load(object sender, EventArgs e)
-
# {
-
# CheckForIllegalCrossThreadCalls = false;
-
# thread_dinleyici.Start();
-
# }
-
#
-
# public void dinle()
-
# {
-
# TcpListener tcp_listener = new TcpListener(30000);
-
# tcp_listener.Start();
-
# while(_shutdown==false)
-
# {
-
#
-
# istemcisoketi = tcp_listener.AcceptSocket();
-
# if (istemcisoketi.Connected)
-
# {
-
# ...
-
# while (rdr_gonderilecek.Read())
-
# {
-
# gonderilecek_data += rdr_gonderilecek["iletiler"].ToString();
-
# }
-
# TcpClient tcp_client = new TcpClient(karsi_ip, 30001);
-
# ag_akimi = tcp_client.GetStream();
-
# akim_yazici = new StreamWriter(ag_akimi);
-
# akim_yazici.WriteLine(gonderilecek_data);
-
# akim_yazici.Flush();
-
# }
-
#
-
# }
-
-
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
-
{
-
_shutdown = true;
-
}
-
In this way the thread's operation gets complete and then the form closes gracefully. I hope this helps.
