Network Programming in .NET

I’m trying to connect to Skype from c#, but not very sucessfully. Hopefully I’ll crack this in the future …

Using the code snippet:

Skype skype = new Skype();
if (!skype.Client.IsRunning)
{
// start minimized with no splash screen
skype.Client.Start(true, true);
}

// wait for the client to be connected and ready
skype.Attach(8, true); // Not 6?

But then skype gives the error:

Another Application (blah.exe) is attempting to access Skype but we are unable to respond.Please try again later.

Although SEHE, the testing app for the API does work, with the messages:
