I am looking to lock my usb pen drive. It should ask for password when i try to open the file in the usb pen drive. Is there any way I can do this using vb.net or c#.

I do not know a programmatic way to do what you want. Someone else may come along who does, but in case not:
1) TrueCrypt has a tutorial here[^] on how to do it with their software, which I believe is free.
2) Zip the confidential data in a password protected *.zip file. There are several free Zip Libraries for .NET. (google)
3) Get a U3 enabled drive such as this[^] one which comes with security enabled. The link is a UK one, but it is the drive that you should look at.

use the cryptography namespace to encrypt the file on the pen-drive?

There is no method to do with without writing an extension to NTFS, which you can't do in VB.NET or C#.

Hi,
I am facing a great problem to make my windows service install itself without installUtil.exe. i read the article Windows Services Installing Themselves but i didnt understand some of the steps. like the code is given and instructed that make a cs file in the service executable project. should i need to have a second project in my windows service project or executable project is the one windows service project. i tried making file in windows service project but got some unexpecetd results.
in the above article i also got a code for main() function where should i put it. coz in my service project there is already a code in the main which is actually starting the service.
please advise, i am very upset.

Hi,
Nowaday I'm working on .net remoting and I've got some problem with leasing.
there is my code:
public class X : MarshalByRefObject
{
public int x;
public X()
{
Console.WriteLine("some X object is done...");
}
public void PrintAboutMe()
{
ILease itfILease = (ILease)RemotingServices.GetLifetimeService(this);
Console.WriteLine("CurrentState: " + itfILease.CurrentState);
Console.WriteLine("InitialLeaseTime: " + itfILease.InitialLeaseTime.Minutes +
":" + itfILease.InitialLeaseTime.Seconds);
Console.WriteLine("CurrentLeaseTime: " + itfILease.CurrentLeaseTime.Minutes +
":" + itfILease.CurrentLeaseTime.Seconds);
Console.WriteLine("RenewOnCallTime: " + itfILease.RenewOnCallTime.Minutes +
":" + itfILease.RenewOnCallTime.Seconds);
Console.WriteLine("SponsorShipTime: " + itfILease.SponsorshipTimeout.Minutes +
":" + itfILease.SponsorshipTimeout.Seconds);
Console.WriteLine("x = " + x);
}
public override object InitializeLifetimeService()
{
ILease itfLease = (ILease)base.InitializeLifetimeService();
if (itfLease.CurrentState == LeaseState.Initial)
{
itfLease.InitialLeaseTime = TimeSpan.FromSeconds(10);
itfLease.RenewOnCallTime = TimeSpan.FromSeconds(6);
itfLease.SponsorshipTimeout = TimeSpan.FromSeconds(6);
}
return itfLease;
}
public void IncrementX()
{
x++;
Console.WriteLine("\nIncrement x member ...\n");
}
public void ChangeLifetime()
{
ILease itfILease = (ILease)RemotingServices.GetLifetimeService(this);
itfILease.Renew(TimeSpan.FromSeconds(20));
}
}
public class MySponsor : MarshalByRefObject, ISponsor
{
public TimeSpan Renewal(ILease il)
{
Console.WriteLine("I've been asked to renew the lease.");
return TimeSpan.FromSeconds(20);
}
}
public static void Main(string[] args)
{
HttpChannel c = new HttpChannel(null,
new BinaryClientFormatterSinkProvider(),
null);
ChannelServices.RegisterChannel(c);
RemotingConfiguration.RegisterActivatedClientType(
typeof(X), "http://localhost:667");
X x = new X();
Console.WriteLine("Client runs...");
x.x = 8;
x.PrintAboutMe();
ILease serverLease = (ILease)RemotingServices.GetLifetimeService(x);
MySponsor sponsor = new MySponsor();
serverLease.Register(sponsor);
x.IncrementX();
Thread.Sleep(8000);
x.ChangeLifetime();
x.PrintAboutMe();
Console.ReadKey();
}
static void Main(string[] args)
{
BinaryServerFormatterSinkProvider serverProv = new BinaryServerFormatterSinkProvider();
serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;
IDictionary props = new Hashtable();
props["port"] = 667;
HttpChannel c = new HttpChannel(props,
null,
serverProv);
ChannelServices.RegisterChannel(c );
RemotingConfiguration.RegisterActivatedServiceType(
typeof(X));
Console.WriteLine("Server runs...");
Console.ReadKey();
}
My first question is:
Whay I can't change CurrentLeaseTime via any way? I think when I increment x member it should change my remote object lease time. I receive the same result when I'm trying to change it by ChangeLifetime() method and even my Sponsor doesn't seem to work.
My second question:
Is any way to catch client remote object on server side? I mean I want to have got a references to client objects.
Thank You in advance!

For the first question, this code runs fine for me and the lease is being successfully renewed.
For the second question, you already are, when you run this code the client is interacting with the remote (ie. proxy) object and the actual object exists and is even outputting text onto the Server's console.
I haven't done much with remoting, but that's my two cents, hope it helps.

I'd like to thank you for help, I found the solution for first problem... I didn't know that:
current lease time = MAX(lease time - expired time,renew on call time)<br /> source: http://msdn.microsoft.com/en-us/magazine/cc300474.aspx
2.
You wrote:
"and the actual object exists and is even outputting text onto the Server's console"
yes, I know but I'd like to have a reference to this object (I want to communicate with it), this remote object is working fine (object is created and managed by client) but everything is working on "background". I have got a primitive way to comunicate with every object by static class members but it's not exactly what I want to.

For the first response, neither did I! I just changed the renewed lease time to 5 days so I could easily see it was working.
For the second, I agree it sounds less than ideal, but I'm not sure how else you would do it. Maybe your design could change a little? Perhaps the client-side object can quietly "phone home" asychronously for some new info? Perhaps the client-side object could raise an event that you handle on the server?

My query is can we design workflows from stored procedure, and if so then how???
Thank youn
