You can use [URL="http://www.dyndns.com/services/dns/dyndns/ddns.html"]DynDNS[/URL]. Basically you run a client on a machine on the dynamic-ip-address-network and that client updates DynDNS with your dynamic IP and they update the host entry. So you could get a host like "DdoubleD.dyndns.com" that always resolves to your dynamic ip address.

Random is time-seeded. Use the [icode]RNGCryptoServiceProvider[/icode]: [code] using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace daniweb { public class Coin { private Side _lastRoll; public Side LastRoll { get { return _lastRoll; } } public enum Side { Heads = 0, Tails = 1 } public Coin() { } …

I'm doubt Microsoft uses them extensively for internal applications, but i'm sure they have just about every OS installed in their corporate headquarters because they need to know what they are competing with. Microsoft doesn't really have a solution for high-load DNS servers and routers, and Microsoft farms their DNS …

You need to call Invoke on the control. Use this method to set the picture from another thread: [code] private void SetPicture(Image img) { if (pictureBox1.InvokeRequired) { pictureBox1.Invoke(new MethodInvoker( delegate() { pictureBox1.Image = img; })); } else { pictureBox1.Image = img; } } [/code]

What do you mean "The funny thing is the pid says it is running on boot"? Scripts in init.d must be referenced from their run levels. Depending on your distro you should have a command for [icode]update-rc.d[/icode] to specify the run levels to execute the scripts. Also the symlink naming …

The Visual Studio IDE uses reflection to render user controls so it is compiling and loading the control which runs the code in the constructur and user control's load event.

Why don't you post the code where you are using the data reader? On the first iteration you need to add the "@opt1" variable to the SqlCommand, and on subsequent iterations you need to .Clear() the parameters, and re-add "@opt1" You could also reference the parameter by name to change …
