Keep a variable that increments the count everytime a new form2 instance is created.

Solution 2

To add to the previous answer, you would do that by incrementing that variable in the form's constructor, as that is called for every instance created.

Solution 3

Declare static variable and increment it on every button click, and show it on message box :)
