Sum of Numbers

Create an application that displays a form similar to the one shown in Figure 5-44. When the Enter Numbers button is clicked, the application should display the input box shown in Figure 5-45.

The Sum of Numbers Problem

The input box asks the user to enter a positive integer value. Notice that the default input value is 10. When the OK button is clicked, the application should display a message box with the sum of all the integers from 1 through the value entered by the user, as shown in Figure 5-46.
