I've already created a publisher policy file but it seems that the application doesn't use this file. Is there anything special to do to make the application use it???

hi all
I want to make chat program using System.Net.Sockets namespace
Chat examples work fine in local area network...
But I couldn't get them work on internet.
I have DSL router..
I setup these on adsl:
NAT(Virtual servers):
Protocol: TCP, External port: 399 Internal Port:399 Internal server IP address: 192.168.1.2 (which my computer's local IP)
am I missing something?

If you are trying to communicate between your computer and another computer through the internet, your internal IP wont resolve to the other computer. You may need to add your internal IP into your Router's DMZ. Another thing that may cause problems is your firewall may be blocking the port you are listening on (399)

Hi
I have recently upgraded from vs2003 - vs2005. I had made some changes to my application and i had simply sent our
customer an updated exe file. When they pasted the file into the installed directory and replaced the existing file
they got an error message appear
"The application has failed to start because the application configuration is incorrect. Re-installing the application may fix this problem"
So, i re-generated the deployment project in vs2005, and tried to run this. when this ran it came up with a warning (see below) and then prompted me to downloadload and install .net framework 2.0, i went through this process and completed the install and the install of my application. but when i went to run my application i got the "The application has failed to start because the ....." error again
has anyone come across this before ? or any ideas on whats wrong ?
Warning which appears when deployment program is run

I have a fire alert application that for no reason what so ever should be closed, this you can fix by adding the following in the Form_Closing event e.Cancel = true;
But how do I hide the closing X icon? 
|
|
|
|
|
The 'x' icon on the upper right is the control box. If you go to your form style, under windows style, change the ControlBox property to 'false'. Although i'm not sure if the user can still close the window by pressing alt-f4. You may need to intercept the key event for this.

When you disable the closing event then it don't care if you alt-f4... only thing that can close it is to kill the process in Task Manager.
But thanks .. for the reply

Is there any way to regain an instance of a class that has already gone out of scope?
For instance:
Private Sub cmdGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGo.Click
Dim i As Integer
For i = 1 To 100
f = New frmTest 'f has been globally declared as a Form
f.Show()
Next i
End Sub
This code instanciates 100 instances of a form and displays 100 forms.
The instance almost immediately goes out of scope due to the for-loop.
Should I now run f.close, only the last form is closed understandebly, but how do i reference the other 99 forms? Garbage collection doesn't destroy them because they are still active on the screen.

By storing them somewhere you can get at. Add them to a collection of some sort, then iterate through the collection.

I'm not at very skilled VB programmer and quite new to Visual Studio 2005. I'm trying from an ordinary batch-script on windows to call a VB program, which - depending on the parameters - should set one environment variable.
I have managed to create the program, and I can see either through registry or through "Environment Variables" in "System properties", that my variable is created and set in either the user or machine environment. But in the command shell (cmd.exe) window I still have no access to the new environment variable.
I imagine the problem is that when launching the cmd.exe you take a kind of snapshot of the environment and works with this "copy".
But how can I refresh the environment so the variable is visible and the new value also?

Exactly, your existing shell won't see env variables created after the shell started. Try to run cmd.exe again on the existing command shell window and see if you can see the new env settings.

Even though the existing sheel can't see new env variables, your code should be able to use them immedediately after they are created.

Thanks for your reply Jun.
But as you wrote:
Jun Du wrote: Exactly, your existing shell won't see env variables created after the shell started. Try to run cmd.exe again on the existing command shell window and see if you can see the new env settings.
I have triede this, but it seems that a new cmd.exe inherits the environment from the old one, so it did not help at all.
In my search after a solution I found:
[^]
But even this have the same problem as I. When you call it from a cmd.exe the same problem arise, I can't access a variable newly created, but I can see it in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
So the big question, what is the trick to get it visible in the current environment?
Rgds,

Not sure if this is what you want, but give a try to Win32 call SystemParametersInfo(SPI_SETDESKWALLPAPER, ...), which can change your desktop wallpaper.

Actually I have seen this with non-.NET programs as well. When an app gets minimized Windows can swap out memory that is not needed and free things up. I just did this with Word and it went down to 1-2M when minimized and then back up to about 5M when it is brought back up front. Another app that we run here at work went from 18M while it was running, down to 1-2M when minimized and then back up to 6M when it was opened again. This definately is not anything to do with .NET itself.
