Im new at doing this Vb and im not understanding the variables to well. I have to code the square root button so that it calculates and displays the square root of a whole number. I have to assign a numeric equivalent of the txtNumber.text property to an integer variable. And assign the square root to a single variable. All using the Sqr function to calculate. Can anyone help me with this? And try and explain to me how to get to remember all the variables? I really appreciate any help Thankyou.
