Working with List Boxes

[Purplelair]

I have a quick question about wrking List Boxes,
How do you "Add" or "Subtract" the items in a list box to output to a a text box??

For an example, you input the numbers 10 and 5, how do you add them together then output the solution to a text box??

Can you access the selectedItem?
read it as a string, and convert it to your datatype (int, float, etc) and then do the needful to post it to the textbox

Shashi 's right here.
In your add or subtract buttons' click events (I'm assuming your using buttons) you need to grab the selected value of the each listview, be sure to cast or parse these values into the correct data type, the perform the add or subtract, then set the textboxes text value to this resulting value (toString of course)
