Open an App using a Registered URL

I found this code snip at Christina's site and found it works well with any registered URL, including those custom URL Protocols that you may register .

string url = @"http://www.ricklafleur.com"; 

Process.Start("rundll32.exe", "url.dll,FileProtocolHandler \"" + url + "\""); 

Register Application as a Url Protocol

There are times when it is appropriate for a desktop application to be called via a URL and be passed data, such as "myprotocol://open?id=100”. The following code shows how an application can self register itself to handle a URL protocol.

public void RegisterUrlProtocol(string myUrlProtocolName, bool force,) 

{ 

RegistryKey rKey = Registry.ClassesRoot.OpenSubKey(myUrlProtocolName, true); 

if (force || rKey == null) 

{ 

rKey = Registry.ClassesRoot.CreateSubKey(myUrlProtocolName); 

rKey.SetValue("", "URL:"+ myUrlProtocolName+" Protocol"); 

rKey.SetValue("URL Protocol", ""); 

rKey = rKey.CreateSubKey(@"shell\open\command"); 

rKey.SetValue("", "\"" + Application.ExecutablePath + "\" %1"); 

} 

if (rKey != null) { rKey.Close(); 

} 

}
