Why use 2 threads? You're introducing complexity unnecessarily.

In the constructor for your main window, I assume you have the InitializeComponent() call that actually initializes your main window. Change that constructor to

public MainWindow()
{
    // Show the splash screen.
    SplashWindow splash = new SplashWindow();
    splash.Show(); // Use Show() instead of ShowDialog, as ShowDialog is blocking, whereas Show() returns immediately.

    // Now that we've shown the splash, start loading our main window.
    InitializeComponent();
}

And when your MainWindow finishes loading (override the OnLoad method or create an OnLoad event handler), you can set the visibility of both forms synchronously.

Wouldn't the splash be blocked by the main form and not receive events? Because that's what I think will happen and most solutions for a splash use threads. Or I could be wrong...

No, the splash will be free to receive events. Using multiple threads to touch different UI components is a widely-known no-no anyways. If you update your splash screen, you may need to call .Update() to force a redraw, however, since the OS is busy loading your main form.

Create a windows service to log user logins

I am trying to create a NT Service that will be able to monitor users logging on and off.
Or an NT service that can monitor an application like Internet explorer opening, running, and closing.

Basically I have an application that I want to run which will pause azureus from downloading. Basically to free up network resources for the user logging in.

I can create a NT service fine but don't know what methods or events to use in the service that will fire off when a user logs in or off in XP

and ideas? Big Grin | :-D

The service geting notified of session logon and logoff events isn't hard. It's the other spec you have...

"Basically to free up network resources for the user loggin in." - WHAT? If a user is loggin onto XP, then there can't be anyone else downloading something. There's no network resources to free up.

You, also, can't stop someone from downloading something, while a user logs on, unless your service is also going to act as a proxy for network access.

Why would you even want to do this in the first place? Logon isn't exactly a network intensive operation.

Its not the logon I want to free up the network for...

I want to free up the network while the user is logged in to the machine.
Basically I will be running azurues on a machine that my family uses. They have all different logins to the machine. Mum, Dad, Sister, etc.

When I have azureus running under my account they can't browse the web becuase I am chewing up all the network. User fast switching allows my account to continue downloading through azureus ... while someone else logs in to browse the web and check their emails etc

I don't want to give them access to my account to pause/stop azurues.
I can build a small app that can talk azurues by using azurus xml over HTTP plugin. This is not a problem. But I don't want to have to have them manually stop/start azurues with this app as they may forget to restart it.

I wanted to make the whole process automated. So I was going to write a NT service that will pause azurues when a user logs in and resume download when they log off.

But I am not sure where to start looking to get the logon and logoff event.
As you say its not hard to do. But I am not sure where to look. It would be good if I could get the user id that is logging on and off So that I can select which accounts will pause azureus and which will allow it to continue running (ie my logon account).

Using CVS to manage Visual Studio.NET solution

Hi,

Recently I have several .NET solutions and I want to manage them by CVS (Concurrent Versions System). I am using WinCVS and I have a few questions:

1.Is there any special linkage of the CVS to the Visual Studio .NET?
2.Is the above way recommanded?
3.How can I know about the version of the .NET solution in the Visual Studio?

Thanks

1. no
2. I think CVS is crap, but your milage may vary
3. It's tied to the IDE VS2002 = 1.0, VS2003 = 1.1, VS2005 = 2.0

Monitor User Login and Logoff via service xp

What events can I monitor to implement in my service so that I can write to a log what time the user logged in and logged off and which user it was.

You can start out with the documentation here: WTSRegisterSessionNotification[^]. You want to pass NOTIFY_FOR_ALL_SESSIONS. I'm not sure how this works out with a service... you probably have to have the correct permissions set up.

[EDIT]Oops... there is a managed alternative. Roll eyes | :rolleyes:

Microsoft.Win32.SessionSwitchEventArgs

private void sessionSwitch(System.Object sender, _
Microsoft.Win32.SessionSwitchEventArgs e)
{
if (e.Reason == SessionSwitchReason.SessionLogon)
EventLog.WriteEntry("sessionSwitch", _
SystemInformation.UserName.ToString() + " logged on at " + _

else if (e.Reason == SessionSwitchReason.SessionLogoff)
EventLog.WriteEntry("sessionSwitch", _

Hello Every body...

1 - When using localhost as SMTP mail server :
550 5.7.1 : Unable to relay for username@gmail.com
2- or (When using mx1.yahoo.com as smtp server) :
550 : Relaying Denied for <username@gmail.com>

How can I solve this problem.
Note : I use FreeSMTP.NET Component to sending Emails(http://www.quiksoftcorp.com/)
Best Regards,

Your mail server doesn't allow sending email to other servers. While yahoo's mail server will never allow relaying, you can configure your local mail server to allow relaying (Right click on My Computer->Manage, Services and Applications, Internet Information Services, right click on Default SMTP Virtual Server, go to the Access tab and click the Relay button).

Hope this helps.

Regards
Senthil

Why would you want to ? I don't see how you could, for starters it happens before your code runs. Perhaps you can *detect* safe mode and refuse to run under it, is that what you want ?

I know how this can be done. But it would be a great learning experience for you. Here's a few tips.

- Know assembly
- Know what goes on in the loader
- Find code that handles F8
- Patch things up... (most likely single byte patch)
- ... done

I hope your doing this for fun and not for some kind of software you're releasing. Besides, this doesn't have anything to do with c#.

I get an error "The object has not been as serializable" when I'm tring to serialize (binary) an class which contains a stream, and some other variables. When I remove the stream object from my class the serialization was successful.

As far as I know, the Stream class is serializable. What may reason of this error.
