When you will call the AddToLog method, depending on which parameter you specify, the correct overloads will be used.

If you call the method with only one string parameter the first overload will be used.
If you call the method with a string and a control parameters, the second overload will be used.

You don't have to specify this. It is exactly like when you call the msgbox method. You have multiple overloads and the correct one is used automatically.
