i created a class using classbuilder in a standard exe. the class had 3 properties
num1(int),num2(int),str(string).
i then added this class to a collection.
my form has 3 textboxes, one for each type of data and a commandbutton
and a listbox to view the added data.

please tell how to add the data through the textboxes
and display them in the list box.
