Calculator keypress [closed]

Answer 1

Assuming that you have buttons for numbers and mathematical operations, you may also do the following:

1. Set the form's KeyPreview property to true
2. Add an OnKeyPress event handler to the form
3. Handle any key necessary

The code to handle the key press could look like:

if (e.KeyChar == '0')
{
    e.Handled = true;
    btn0.PerformClick();
}

That means: If the '0'-Key is pressed, programmatically push the button that stands for 0. You can handle *, / etc. in the same way.

EDIT

Of course I assume that you have assigned a click event to the respective buttons that already do what you want to do (e.g. add number to display, perform operation on numbers and display result, etc.).
