Simple Async HTTP Request

by Manuel 7/24/2008 8:25:00 AM

Since .NET Framework 2.0 there is a very easy way to perform an asynchronous HTTP request and retrieve the result as a string.
The System.Net.WebClient class provides methods and events to handle this task in a very convenient way:

using System.Net;

private void Button_Click(object sender, RoutedEventArgs e)
{
   string topic=this.SearchTextBox.Text;
   string url = "http://yourserver.com";
   WebClient client = new WebClient();
   client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
   client.DownloadStringAsync(new Uri(url));
}

void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
   if (e.Error == null)
   {
      string result = e.Result;
   }
}

Remote Desktop Console

by Manuel 7/24/2008 5:03:00 AM

Windows XP:

Use your_computer_name / console

Windows Vista

Use your_computer_name /admin

To simulate Ctrl-Alt-Del press Ctrl-Alt-End. Pressing Ctrl-Alt-Del will open the Task Manager on the local machine.

Reboot and restart:
- "shutdown" to shutdown
- "shutdown -r" to reboot
- "shutdown -i" to get a GUI
- "shutdown -l" to logoff

The MS client also allows Ctrl-Alt-Break to switch between viewing the session in a window and on the full screen.

To change the port number of the remote desktop server:
The setting for the Terminal Services port lives in the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp
Open up Regedit, find this key, look for the the PortNumber value and change it to whatever you want.

To connect to a remote server with a non standard port (other than 3389):
Use the computer name, followed by a ":" and the port (e.g. www.mymachine.com:6789)
