Though i am unable to understand fully what you want, but from what i get (that you want to write this string to some other system) you are in need of remoting.

What if they just edit the hostsfile again to "unblock"?

I suppose you could block those sites at the router, or with your DNS if you have a proper DNS service (OpenDNS for example)

It would depend on the router you're using

If you have network administrators in your organisation, why don't you let them worry about blocking sites. There already existing solutions(firewalls) that handle that kind of thing. Whatever solution you come up with is likely to have lots of holes.

And you're trying to do this without any networking knowledge??

You know its a good day when the climax to a long list of message posts ends with such a humorous response. It makes you remember why you bother reading these kind of posts in the first place.

Requirement is like this,

Events will be present for a week.(Same like Orkut Events)

On a single day there can be more than one event at different times.

Based on user login the user should see the events,if he log's in after the scheduled event time then only "Descripition" (Database field ) of the event should be seen else Events-Name,UserName,Image will be displayed.

My problem is I need to show only 7 records all together irrespective of Number of events present for that week i.e for 7 days in a week 7 records only. In each record more than one event can be present (or) if present should be displayed .

For achiving this task I can take any of the data presentation control,but i dont seem to get any idea of solving this requirement. It would be gr8 if any one helps me out Its Urgent.Thanx In advance.

Cannot upload chinese named file into Ftp server.

hi everyone,

I am facing big problem in Ftp upload function.

When I run following code for english named file uploading It's ok. No problem. But when i try for chinese named file. I got this error message.
"The remote server returned an error: (550) File unavailable (e.g., file not found, no access)."

Let me know if you have solution for me. Thanks in advance. Smile | :)

~~ This is my source code ~~

// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("XXX" + Path.GetFileName(this.txtUploadFile.Text));
request.Method = WebRequestMethods.Ftp.UploadFile;

// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential ("XXX","XXX");
request.UseBinary = true;
request.UsePassive = false;
request.KeepAlive = false;
            
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader(this.txtUploadFile.Text);
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());  

sourceStream.Close();
request.ContentLength = fileContents.Length;

Stream requestStream = request.GetRequestStream(); // Error occurring in here

requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();

FtpWebResponse response = (FtpWebResponse)request.GetResponse();

How to create something like unions in C#?

CelestialCoder27-Oct-09 23:40

I have to load a single byte array of 64 elements.( from a USB device - which I have already done using HID examples in net)
Actually this 64 bytes is 4 groups of 16 bytes each.

I need to load this as a array of 64 bytes and process it as 4 structures of 16 bytes each.( In Microcontroller C programs I use Unions)

Which is the apt method in C#? and How?

Thanks

With Regards

You can create a struct in C# and specify how much space each variable takes up. I forget the syntax, but I know you can.

Just found this with google:

using System.Runtime.InteropServices;
[StructLayout(LayoutKind.Explicit)]
struct ByteArray {
[FieldOffset(0)]
public byte Byte1;
[FieldOffset(1)]
public byte Byte2;
[FieldOffset(2)]
public byte Byte3;
[FieldOffset(3)]
public byte Byte4;
[FieldOffset(4)]
public byte Byte5;
[FieldOffset(5)]
public byte Byte6;
[FieldOffset(6)]
public byte Byte7;
[FieldOffset(7)]
public byte Byte8;
[FieldOffset(0)]
public int Int1;
[FieldOffset(4)]
public int Int2;
}

timers in windows service

I added to windows service design view a timer. I start it to say 2000ms in service custom command, and dump to log file that it was started indeed, by checking enabled property.

However, the timer event does not happen? (I dump to text file in the same way each timer tick)

I checked that in Designer.cs the timer was properly created and timer handler attached.

Is there a special timer processing in services?

The problem can be that normally a service doesn't have a window and if I'm right the normal way a timer
catches the tick event over the main window proc.

At first you can try to let your service "interact with desktop".
Second I would try to use this class instead http://msdn.microsoft.com/de-de/library/system.threading.timer.aspx.

Hi,

Below code will Help you

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.ServiceProcess;
using System.Text;
using System.Timers;
using System.IO;

namespace service
{
public partial class Service1 : ServiceBase
{
Timer t = new Timer();
StreamWriter writer = new StreamWriter("C:\\Service.txt");
public Service1()
{
InitializeComponent();
}

protected override void OnStart(string[] args)
{
t.Elapsed += new ElapsedEventHandler(t_Elapsed);
t.Interval = 60000;
t.Enabled = true;
writer.WriteLine("Service is Started");
writer.WriteLine("Timer has been started..");
writer.Flush();
}

void t_Elapsed(object sender, ElapsedEventArgs e)
{
writer.WriteLine(DateTime.Now.ToString());
writer.Flush();
}

protected override void OnStop()
{
t.Enabled = false ;
writer.WriteLine("Service is Stopped");
writer.Flush();
}
}
}

Thanks,
Sunil G.
