If you call sub form non-modally, it will run in diffrent thread. Why do you want to use non modally?
And if you want to block executing main form and wait till status form is finished, it is easy if you called it modally with ShowDialog() method.
And if you insist in non moddaly, make some static variable in status form boolean type, and in the main forum ovverride focused event
PS: Moddaly and non moddaly means only that it runs either in diffrent or same thread

I don't think so. It means they use different message pumps, however all message pumps are executed (one at a time) by one and only one thread.
Here is an experiment to prove it:
- create main form Form1 with a ListBox and a Button; it will be shown modelessly;
- create Form2 with a ListBox and a Button; it will be shown modally;
- add the following to Form1:
public partial class Form1 : Form {
int count;
public Form1() {
InitializeComponent();
}
public void log(string s) {
lb.Items.Add(s);
}
private void button1_Click(object sender, EventArgs e) {
log("Thread ID="+Thread.CurrentThread.ManagedThreadId);
Form2 f=new Form2();
f.ShowDialog();
}
protected override void WndProc(ref Message m) {
count++;
if (count<5) log("Thread ID="+Thread.CurrentThread.ManagedThreadId);
base.WndProc(ref m);
}
}
- add basically the same code to Form2 (without new Form2/ShowDialog)
- run, click button, see all thread IDs, on second form, click button, see all thread IDs equal to the former ones.

I want to create a pemanent connection with windows application and webserver(sending/receiving bytes anytime). Like as I run application in my pc then it should connect to my webserver and keep connect untill application closes. I thought to use HttpWebRequest/Response but I didn't find it accurate way. Thought about Socket but it confuses about webserver. So before I try to implement anything I would like to know any better idea or any suggestion you guys like
thanks

i'm no profesional, but a webserver isn't designed to keep the connection.
you make a request, the webserver serves the requested data and that's it.

They're not using HTTP for the communication.

you don't need a connection with the webserver.
you can use POST or GET to send data, a neat script/application on the webserver wil crunch the data and sends the wanted (result) data back to you.
you windows desktop aplication can use timers to pol the webserver every X time.

okay I should put a timer of interval 1000 and in Tick event a Request and a Response will happen...so wont the application take too many system resources ?

1000 = 1 second.
60 ticks per minutes, makes 3600 per hour.
don't you think that's why to much?
no for the computer it's pratically nothing in recources.
i used to run more than 30 instances of the same application each consuming more than 30mb ram.
Second life ---> libsecondlife.org
but depending on the webhost you have, they count the traffic.
atleast mine does, www.web.com
if you own the webserver and traffic is not an issue, use PERL, Phyton or something and write an application outside of the webserver.
than your problem is solved and you can have a live connection.
smart people use a SQL table as ram, a RAM table, you can create ram table(mysql, sqlite, etc, etc, do this), but you can use an ordinary table and do the same.
so you application aswel the webserver can acces this table.

Do you have to use C# for this? I do things like this a lot, as I write test automation suites for websites.
I would use the AutoITv3 scripting language, http://www.autoitscript.com. It should take you all of ten minutes to do something simple like this, and the scripts compile directly .exe.
Take a look

If i want to create an application without any console and without any form that for example:
1. every 20 hours send an email
2. backup some folder or doing anything without the user interaction.
3. Will write a log to a file.
4. will run a process if some event occur.
I know that i can make a form application but then i need to mark the form with 0% Opacity. That will take a lot of memory for the process.
What is the best way?

write it as service. But why do you need such app. Such app can be easly considered malicious programs
|
|
|
|
|
Thanks.
I need it to backup files in my system and to sync between some computer in my office.
|
|
|
|
|
Then i suggest writing it so that it will move to system tray
|
|
|
|
|
Why not try chucking it in the system tray?

you can't make an application without a window.
but you can hide it.
you can make a DLL and hook it windows explorer, like a service or something.
but don't ask me how to do it, because i never tried

That is only expection for service. They don't have any window.

Your sig says it all - you are quite wrong. A windows/web service does not cannot have a form.
This is lousy advice, although admitting you have no idea at least puts it in context. Please be a little more careful about what advice you give. If you had been the first responder and the asker was a newbie then you may have damaged a potential developer.

eh, i remember i asked the same question when i played with MFC c++ 5,6 years ago.
it's impossible for an normal application to operate without a form/cmd.
than as solution, i said, you can write a DLL and hooked it the windows explorer, be it as service or something else, like a virus.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Threading;
namespace nowindow_application
{
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Thread.Sleep(1000);
Main();
}
private static int bobo(int a, int b)
{
return (a + b);
}
}
}
this application wil not not produce an executable file using visual studio 2008
//MessageBox.Show(bobo(1, 2).ToString(), "", MessageBoxButtons.OK, MessageBoxIcon.Information);
uncomment this file and you have a executable file in your bin folder.
so you can't build a application without a CMD or form layout.
i dind't spread any false hope or something, i asked this question before.

or try to compile this

using System.Linq;
using System.Windows.Forms;
using System.Threading;
namespace nowindow_application
{
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
bobo(1, 2);
Thread.Sleep(1000);
Main();
}
private static int bobo(int a, int b)
{
return (a + b);
}
}
}
