Hey All,
I created a calculator with an online tutorial, but it is very basic. I wanted to include keyboard functionality. For example i currently am unable to use my key board to do "6 + 9". I need the "6" to be stored when the "+" on the keyboard is pressed. Any suggestions?
public Form1()
{
InitializeComponent();
}
double total1 = 0;
double total2 = 0;
bool plusButtonClicked = false;
bool minusButtonClicked = false;
bool divideButtonClicked = false;
bool multiplyButtonClicked = false;
bool KeyDown = false;
