[ WPF ] How to execute a * .exe with a button in a main window, whose path is in a TextBox of a second window, please help me.

Question

Hi, I'm still a newbie. I have my project, in which I have 2 windows, a Main Window (Launcher.xaml) and another Second Window (Configuration.xaml). In the Main Window I have 2 buttons; a button that executes an * .exe (start game), whose path or address is in a TextBox in the second window. And the second Button calls the second window.

In the second window I have a TextBox and 2 Buttons, One is the one that calls the "OpenFileDialog" that when clicked, sends me a search dialog for the * .exe file (game.exe) and when I choose that program to execute, this write the address or path in the TextBox something like this; "D: \ folder \ game.exe". The following button saves the direction or route of the game to be able to execute it in the main window.
Well my question is how I can make the button of the main window (Start Game) execute the game whose address or path is in the TextBox of the second window, I would be very grateful if you could help me with it, please. Or some other alternative, I am already very grateful for it and its help.

I attach an image of my project:

I also attach my project file:

I will show you a easy way not using ViewModel to get the date from the child window.
1.Add the below code to your MainWindow.xaml.cs

 string ExeFileName;  
        public void GetExeFileName(string value) { ExeFileName = value; }  
        private void BtnEscogerJuego_Click(object sender, RoutedEventArgs e)  
        {  
            RutaDelJuego ConfigRuta = new RutaDelJuego();  
            ConfigRuta.sendMessage = GetExeFileName;  
            ConfigRuta.ShowDialog();  
        }  

2.Add the below code in your WpfLanzarJuego.Xaml.cs:

 public delegate void SendMessage(string value);  
        public SendMessage sendMessage;  
        private void BtnGuardarSalir_Click(object sender, RoutedEventArgs e)  
        {  
            sendMessage(RutaTextBox.Text.ToString());  
            this.Close();  
        }  

3.You can use the below code to host the exe in your MainWindow:

Hi Jack,
without ViewModel you can use for DataContext in second window the CodeBehind of MainEindow:

<Window x:Class="WpfApp1.MainWindow"  
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"  
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"  
        xmlns:local="clr-namespace:WpfApp1"  
        mc:Ignorable="d"  
        Title="MainWindow" Height="450" Width="800">  
  <StackPanel>  
    <Button Content="Load Second Window" Click="Button_Click_1"/>  
    <Button Content="Execute exe" Click="Button_Click_2"/>  
  </StackPanel>  
</Window>  

CodeBehind:

Hello Miss DaisyTian-MSFT, and Mr. PeterFleischer-3316. I am very very grateful for your help, I am beginning to understand the "Binding, command and ViewModel". With a little self study I will understand that even more.

Miss "DaisyTian" I like your code very much and I am doing tests and learning from it, I realize that I am just beginning to climb the mountain of programming in C # WPF, thank you very much ...

I hope you have a good day and it will always be good for you. A warm hug from Peru. Thank you very much thank you friends ...
