C++ Windows forms with .cpp

[Riven]

I am still trying to learn how to make windows form applications in visual studio. I have created a very basic windows forms application. But, I am not sure how to call my functions from the header to use for when the button is pushed. There seems to be very little reference tutorials about using the windows form application in visual studio.



As you can see I have a very simple window with a button named "button1" and a label named "label1".

What I want to do is when you click the button it calls the function which will add die1 and die2 together in my random_dice_wfa.cpp part of my code. Which will then return the total dice roll number to be displayed in the label as the answer.
