I am trying to build a program in Visual Basic that allows user to enter an objects mass and velocity and to display the Kinetic energy. The application should have a function KineticEnergy that accepts a moving objects mass and velocity as arguments. The function should return the objects KE.

i get these three errors when trying to run the program I need help how would I fix this so it runs successfully? Thanks in advance!

Answer 1

You did not supply a WithEvents variable in your Handles clause. The Handles keyword at the end of a procedure declaration causes it to handle events raised by an object variable declared using the WithEvents keyword.

//note if i can see the code i can make modifications in it

for more details you can go through this link

if you cant get it comment the code i will modify it.
