 6' This sample demonstrates how to pass value between forms.
 7'  
 8' There're two common ways to pass value between forms:
 9' 
10' 1. Use a property.
11'    Create a public property on the target form class, then we can pass value to the target 
12'    form by setting value for the property.
13' 
14' 2. Use a method.
15'    Create a public method on the target form class, then we can pass value to the target 
16'    form by passing the value as parameter to the method.
