Maybe they don't. MSN sure doesn't need it, all messages go through MS-servers (so beware..)
Azureus could do without, speeds will suffer but oh well.. But in any case, I don't know how they it would even be possible to forward a TCP port without UPnP. For UDP ports you could use hole-punching.

When i open msn it does config a port on my router i cheked it through admin
it open an udp port maybe my box is preset to only allow msn do that.
i'm prety sure my box has a upnp function just its maybe restricted to famous programme.
so what is the principe of hole-punching TCP does it allow a server listen to this port and receive soket? is it how emule/azureus does work?.

A router that would allow TCP hole-punching would be "broken".
UPnP is "difficult", there are far too many different implementations in routers, some of them really generous and allowing even the most the malformed request to open a port, others nitpicking about the number of spaces and refusing to even tell what went wrong.
Ok so MSN does open a port? It still shouldn't need it but ok.. could you see whether it was UPnP-forwarded or opened as the result of outgoing packets?
The router can not know that it was MSN though, so whatever it did, you can do the same. I recommend you use WireShark/Ethereal to capture how it opens the port (and look at Azureus as well, of course)

Hello Forum.
I am building an application where menu to call the forms are table driven,
I can call the forms by using reflection as follows, however I need to verify first if this form is not open yet, and if it is just set the focus on this form.
My question is, how can I find out if the form is already open?
Thank you very much for your help
Assembly myAssembly = Assembly.GetExecutingAssembly();
Form myForm = myAssembly.CreateInstance(this.GetType().Namespace+".Form2") as Form;
myForm.Show();

I have a simple application timer program - allows any executable to launched, with command line arguments (optional) and terminates after specified number of minutes.
Here's how I'm currently terminating timed process:
while (true)
{
if (dtEndTime <= DateTime.Now || p.HasExited)
{
if (!p.HasExited)
p.Kill();
break;
}
System.Threading.Thread.Sleep(500);
}
Rather straight forward and works most of the time. A crash occurs when I am timing a program called Fraps.exe and its minimized to the tray. The crash itself doesn't always have the same results.
What is consistant is:
- the app Kill() is called for IS closed
- a crash occurs
What varies:
- another app in the tray will crash as well (intermittently)
If I do not minimize Fraps.exe to the tray no crash occurs (however, leaving it on the desktop is not an acceptable solution). Fraps can be closed via task manager without issue.
Any suggestions on how to terminate an external application more gracefully? Process.Close() and Process.CloseMainWindow() have already be ruled out for the case of being in the tray. I'm open to anything will work and not cause a crash.

Use <pre></pre> tags around your code. (Use the code block widget below the reply area rather than type them if you prefer.)
Then format the code, you know indenting and so on, to make it readable, and you might get some answers. Probably not though.
If you like the code you have written then make an article around it and submit it in the normal way.

Hi,
Is there any way to get the following to work?
bool s = _myProperty == true ? Method1() : Method2();
Or is this just silly talk? 
|
|
|
|
|
Yes so long as the return types of Method1/2 are bool also.
|
|
|
|
|
I believe they (method1/2) would also have to be static (?)

Only unless the method that is using this code is also static... otherwise they dont need to be. From the looks he is testing an internal variable so chances are it wont be static.
Edit: But it could be static even if it wasnt static... could go either way.

Why doesn't it work? It should, as long as Method1() and Method2() return bool, or return types convertible to each other and to bool.

Good lord, I still remember that post on your blog. I asked a few people, and nobody knew it! I wonder why they made that restriction.

Hi,
I see ... the problem was the methods are void return types. Can this be used with void?
Cheers,
|
|
|
|
|
No, the expression containing the ternary operator must be of some type. If both the methods take no parameters, this will work
Action result = p ? new Action(M1) : new Action(M2);
result();
|
|

It should work, if both Method1 and Method2 are static and retrun a Bool value.
|
|
|
|
|
I don't get it, why should the methods be static?
|
|
|
|
|
They dont need to be as I said earlier... i.e.
class Conditional
{
private bool _myProperty;
public bool MyProperty
{
get { return _myProperty; }
set { _myProperty = value; }
}
public bool DoSomething()
{
bool s = _myProperty == true ? Method1() : Method2();
return s;
}
public bool Method1()
{
return true;
}
public bool Method2()
{
return false;
}
}

sorry on that - I had another issue on my mind when I read the question and posted that. I just thought of how I would stick that in a console app - where method1 & 2 were helpers to Main (ie. methods in the Program class) - in which case static would be required. But on considering.. should have just posted my own question quietly.

Hello there,
Can anyone name me a site where I can download a huge or a limited quantity of icon files (*.ico images)!
Your help will truly be appreciated,

Have a Google for free icons, loads of hits. You'll have to select what suits you, for yourself though.
