I like to use vi http://en.wikipedia.org/wiki/Vi. It is fairly easy to use.

vi /etc/X11/xorg.conf

Use the down arrow to go to the DefaultDepth setting and the right arrow to get over to the 24. Then you use the d -> space, to delete the 2 and the 4. Then select Esc, though I do not believe you have to, it has become habit for me to esc before moving on to a different command. Next you want to use the i key to begin inserting the new text. Type 16 at this point. Once you have that finished, select Esc -> : -> wq! -> enter. This will force the save.

You should now be good to go.

Actually, you dont need to inherit INotifyPropertyChanged for both classes Contact and Company since ObservableCollection already provides notifications.

From msdn
http://msdn.microsoft.com/en-us/library/ms668604.aspx

ObservableCollection(T) Class definition:
“Represents a dynamic data collection that provides notifications when items get added, removed, or when the whole list is refreshed.”

I took the example, got rid of the notifying setters and it works find!

Contact would be:
public class Contact
{
public int Id { get; set; }

public int CompanyId { get; set; }

public string FirstName { get; set; }

public string LastName { get; set; }

public Contact(int id,
int companyId,
string firstName,
string lastName)
{
this.Id = id;
this.CompanyId = companyId;
this.FirstName = firstName;
this.LastName = lastName;
}
}

The only reason I didn’t mention changing the fixmint.bat file was because if someone isn’t comfortable editing the file, inserting the USB drive first is easier. But your method is easier if you already have the have the fixmint.bat file and are comfortable editing it.
