I am currently attempting to create a MIPS emulator using WPF.

In a stack panel control called registerList; I created 32 stack panels (named C0 to C31) that each contain 2 textblocks (second textblock named R0 to R31).

I initially display the 32 registers contained on Procesor.RegisterBank.Registers[i] correctly using the displayRegisters() method I created.

I made a method to update all 32 values of second textblocks with the values contained on a class called Procesor.RegisterBank.

However when attempting to use this method, the GUI page will not display when I start the project.

I've been stuck on this for hours and almost considering not creating the stack panels via code.

Thanks

 public partial class MainWindow : Window
{
    MRA.MRA Procesor = new MRA.MRA();
    public MainWindow()
    {
        InitializeComponent();
        displayRegisters();
        Procesor.RegisterBank.registers[1] = 69;
        updateRegisters();
    }

    public void updateRegisters()
    {
        for (int i = 0; i < Procesor.RegisterBank.registers.Length; i++)
        {
            var register = (StackPanel)registerList.FindName("C"+i.ToString());
            var content = (TextBlock)register.FindName("R"+i.ToString());
            content.Text= Procesor.RegisterBank.registers[i].ToString();
        }
    }

    public void displayRegisters()
    {
        for (int i = 0; i < Procesor.RegisterBank.registers.Length; i++)
        {
            var register = new StackPanel { Orientation = Orientation.Horizontal, Background = Brushes.White, Margin = new Thickness(6, 6, 6, 6), MinHeight = 25, Name = "C" + i.ToString() };
            var registerName = new TextBlock { Text = "R"+i.ToString(), FontSize = 16, MinWidth = 30, Background = Brushes.DarkGray, Foreground = Brushes.White};
            var registerValue = new TextBlock { Text = Procesor.RegisterBank.registers[i].ToString(), FontSize = 16, MinWidth = 100, HorizontalAlignment = HorizontalAlignment.Right, Name="R"+i.ToString()};
            register.Children.Add(registerName);
            register.Children.Add(registerValue);
            registerList.Children.Add(register);
        }
    }
}

You have to use RegisterName() , so that newly added Control can be part of the NameScope of parent control.

Add these lines at the end in your displayRegister() method :

NameScope.SetNameScope(register, new NameScope()); register.RegisterName(registerValue.Name, registerValue); registerList.RegisterName(register.Name, register);
