First, sorry for my poor english Big Grin | :-D

If u want connect two computer through internet for your application(using socket programming or wcf). U must open port of your modem.
Example: server application use port 8080 to listen client connect to. U must open port 8080.
To open port, run cmd, type ipconfig, enter. The default getway is Ip of modem. Type this IP on IE or FireFox... to access modem, (require usename and password). U cant find the way to open port modem here http://portforward.com/[^]
Client app can connect to your server app if it use correct global IP and port, u can use this page to know your global IP (dynamic IP) http://ip2location.com
Note: if u test your app, both client and server on a computer or computers on LAN, u cant use this global IP (instead LAN IP, or loopback IP). U can get your friend(certainly, use a computer connected internet) to help you.
IF ur app use wcf, u must set security mode in config file to "none" (this is the easiest way Big Grin | :-D

But.. If I can't access the router/modem?
With this example, I can connect a computer to a gateway.
I want to gateway could redirect this connection to a sub-network computer.
I'll search more about WCF, I don't know what it is.
Thank you!

I think this post is what you want!
Vista Aero ToolStrip on Non-Client Area[^]

By the way, if you want to enlarge the titlebar, try this one:
Windows Vista Aero Glass in .NET Managed Win32 Applications[^]

Mixing the two examples, you can make apps like this: http://twitpic.com/cxzy8[^]

Hehe, I was searching for these examples since April.. xD
Now, I'm very happy! =P

Hi Let's assume that I have 2 forms, the main form and the form that main form opens (Form2).

In the first form I have a button - when pressed it opens Form2 and closes the main form -. It closes main form and opens Form2 with this code:

this.Hide();

using (Form2 _Form2 = new Form2())
{
   _Form2.ShowDialog();
   this.Dispose();
}

this.Close();

When I press that button main form closes and Form2 opens without a problem, but main form doesn't get destroyed. If main form is doing something on it's thread it keeps doing it at background. I want the main form to be completely destroyed. How can I do this?

Thanks.

Hi,

Form.ShowDialog() waits for the new Form to be closed, so your Dispose statement isn't helping at all.
Try this:

this.Hide();
_Form2.ShowDialog();
this.Show();   // optional

When I open Form2, I want main form to be completely destroyed but in your code it doesn't get destroyed too.

A thread is working in main form and it keeps doing what it does after the main form is closed and form2 is shown. I don't want main windows to keep doing anything.

That does not make sense. A thread does not live inside a Form, a thread is a piece of code, any code, executing on a processor, and a Form is a GUI component. Maybe your Form class created and started the thread, destroying the Form would not stop such a thread, unless you do it explicitly in a destructor/finalizer but I doubt very much that is what you are doing.

If you want a thread to stop doing what it does, then tell it to stop by setting some flag, and have the thread check that flag regularly. Killing/aborting a thread the hard way isn't a very good idea.

How can I set a flag and then stop that thread with a destructor/finalizer?

Luc Pattyn18-Jul-09 3:53

18-Jul-09 3:53

you don't need a destructor/finalizer to stop a thread.
Here is a pseudo-code example:

Thread thread;
bool cancel;

void start_Clicked() {
    cancel=false;
    thread==new Thread(...threadCode);
    thread.Start();
}

void stop_Clicked() {
    cancel=true;
}

void threadCode() {
    while(!cancel) {
        .. do something useful
    }
}

thas is cooperative thread control: the thread is doing some of the controlability work itself (the while test)

Your english seems fine, I'm just having trouble seeing the relevance of the question to a C# forum or programming in general.

Who's html code, yours or another site. Some detail of what you are trying to achieve may be useful.

Hi,

there are many ways to get such information.
One is by looking at some of the environment variables (e.g. WINDIR).
An easier one is using Environment.GetFolderPath(SpecialFolder.System)
