I added Language="se-SE" for Equation and Display Label in the xaml, and updated the cs code like below:
public partial class MainWindow : Window
{
Double Value = 0; // Store Decimal and Int Values if needed
String Operand; // Store the Operand - Will Determine the Maths
Boolean OperandPressed;
public MainWindow()
{
InitializeComponent();
}
private void Clear_Click(object sender, RoutedEventArgs e)
{
Value = 0;
Display.Content = "0";
Equation.Content = "";
}
private void CE_Click(object sender, RoutedEventArgs e)
{
Display.Content = "0";
}
private void Button_Click(object sender, RoutedEventArgs e)
{
Button B = (Button)sender; // Cast Generic Object To Buttom
//To Get Rid of the Initial 0 in the Display
if ((Display.Content.ToString() == "0")||(OperandPressed))
{
Display.Content = " ";
}
// If Decimal Point already exsists within the Display then do not add another Dedcimal Point
if (B.Content.ToString() == ".")
{
if(!Display.Content.ToString().Contains("."))
{
Display.Content = Display.Content.ToString() + B.Content.ToString(); // Append Number onto Display
Display.Content = Display.Content.ToString().Replace(".", ","); // Update the Equation Label
}
}
else
{
Display.Content = Display.Content.ToString() + B.Content.ToString(); // Append Number onto Display
Display.Content = Display.Content.ToString().Replace(".", ","); // Update the Equation Label
}
OperandPressed = false;
}
private void Button_Operand(object sender, RoutedEventArgs e)
{
Button B = (Button)sender; // Cast Obj to Button
// Continously operate on the current results without having to press equals.
if(Value != 0)
{
Button_Equals(this, null); // emulate the equals button press
Operand = B.Content.ToString(); // store operand
OperandPressed = true;
Equation.Content = Value + " " + Operand; // Update the Equation Label
Equation.Content = Equation.Content.ToString().Replace(".", ","); // Update the Equation Label
