When close Windows Form, the process still running

Hi Valza,

could it be that you started some thread that was not a backgound thread. Threads that are not background threads keep an application from exiting. Can you check that?

Cheers

You probably will still need to show a snippet of your Host (console app) if you are using a console app to spawn the form.
Based on the code you have posted I'd check the following:

1. Make sure when you call this.Close() the "this" reference is referring to ClientForm. Try putting breakpoints and see what happens when you debug this when closing the form.

2. As you called this.Hide() which hides the ClientForm and shows TestuForm it is possible when you closed the application you only closed TestuForm but not ClientForm. Did you attach an event to TestuForm's Form.Closed to also close ClientForm?
In short, make sure the "this.Close()" is called when you close your app from the user interface.

The app.config is most likely just a warning and shouldn't affect your form closing issue.

When u closing the form,
Add this code,

End 'For VB

some thred is still running , so close ur application when all threds completes their process ,and u have to also free the memory that the threads are using .

HI, Edbert P & ManfrerRbihy.

ClientForm is Main form.
TestuForm is subForm.

I'm using WCf.

IService1 channel = null;
       NetTcpBinding bining = new NetTcpBinding();

&

private void ClientForm_Load(object sender, EventArgs e)
       {
           try
           {
               bining.Security.Mode = SecurityMode.None;
               var endPoint = new EndpointAddress("net.tcp://localhost:8080/Service1");
               channel = ChannelFactory<IService1>.CreateChannel(bining, endPoint);
               lblBinding.Text = string.Format("IP: {0}", endPoint.Uri.Authority);
           }
           catch (Exception ex)
           {
               MessageBox.Show(ex.Message);

when I exit ClientForm I use:

private void izietToolStripMenuItem_Click(object sender, EventArgs e)
        {
            this.Close();
        }

ON button:

testID = new TestuForm();
           testID.SelectedTestID = _selectedTestID;
           testID.SelectedSkolenuID = _selectedSkolenuID;
           testID.SelectedSkolotajuID = _selectedSkolotajuID;
           testID.Show();
           this.Hide();

I pass some variables to TestuForm() & hide ClientForm.
on TestForm i use same channel,binding

IService1 channel = null;
NetTcpBinding bining = new NetTcpBinding();

private void TestuForm_Load(object sender, EventArgs e)
        {
            bining.Security.Mode = SecurityMode.None;
            var endPoint = new EndpointAddress("net.tcp://localhost:8080/Service1");
            channel = ChannelFactory<IService1>.CreateChannel(bining, endPoint);
        }

I have tried only open and close ClientForn but still have the problem.
the sutpid process name is WindowsClient.vshost.exe
Description vshost.exe

a few minutes ago I runed the program -> closed.
some times process closes, sometimes not.
Sometimes I just click End Process Tree it closes.
Sometimes I need to try close multiple times before it closes.

this program is my first project I'm playing with C# only about 2 months.
So bee nice. :)
thanks.

I just noticed that in my app.config file is sometinh like this

<transport clientCredentialType="Windows" proxyCredentialType="None"
                           realm="">
                           <extendedProtectionPolicy policyEnforcement="Never" />
                       </transport>

extendedProtectionPolicy is underlined by a blue wavy line
and it says:
The element 'transport'cannot contain child element 'extendedProtectionPolicy' because the parent element's content model is empty.

maybe this is the problem?
