The user enters an integer into a text box and clicks on the Calculate button. The application will sum all of the integers from 1 to the number entered and display the sum in a label. The sum of numbers is the sum of all the numbers from 1 to the ending number. For example, if the user enters 3, the sum of numbers is 1 + 2 + 3 = 6. If the user enters 5, the sum of numbers is 1 + 2 + 3 + 4 + 5 = 15. Your program should work for any integer entered by the user.

Use a loop to calculate the sum of numbers. You will need to initialize the variables and assign appropriate values. Get the value for intEndNum from the textbox. After the loop has run, display intSum in the label.
Here is one way to code the loop:
For intCount = 1 To intEndNum
intSum = intSum + intCount
