Integrate the electronjs application inside the Wpf application

Question

I have WPF application in that i want to render the electronjs app inside the window frame. actually, I am able to load electronjs application but as separate application not in window frame. Please find below code:

{
process = new Process();
process.StartInfo.FileName = @"xyz.exe";
process.StartInfo.Arguments = "-parentHWND " + hWnd.ToInt32() + " " +
Environment.CommandLine;
process.StartInfo.UseShellExecute = true;
process.StartInfo.CreateNoWindow = true;
process.Start();

            process.WaitForInputIdle();  

}

Frame are used to jump between pages. You could use WindowsFormsHost to host other applications.

Xaml:

<Grid   x:Name="test">  

    </Grid>  

Codebehind:

using System;  
using System.Diagnostics;  
using System.Runtime.InteropServices;  
using System.Threading;  
using System.Windows;  
using System.Windows.Forms.Integration;  

namespace OpenEXEInWpf  
{  
  public partial class MainWindow : Window  
  {  

    [DllImport("user32.dll")]  
    public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);  

    [DllImport("user32.dll", SetLastError = true)]  
    public static extern int GetWindowLong(IntPtr hWnd, int nIndex);  

    [DllImport("user32.dll")]  
    private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);  

    [DllImport("user32.dll")]  
    private static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int x, int y, int cx, int cy, int uFlags);  
    public IntPtr _appWin { get; set; }  

    private Process _childp;  
    public MainWindow()  
    {  
      InitializeComponent();  
      Loaded += (s, e) => LaunchChildProcess();  

    }  

    private void LaunchChildProcess()  
    {  
      string exeName = @"C:\**\PreventKeyboardInListview.exe";  
      var procInfo = new System.Diagnostics.ProcessStartInfo(exeName);  
      procInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(exeName);  
      procInfo.WindowStyle = ProcessWindowStyle.Minimized;  
      _childp = Process.Start(procInfo);  
      System.Windows.Forms.Panel _pnlSched = new System.Windows.Forms.Panel();  
      WindowsFormsHost windowsFormsHost1 = new WindowsFormsHost();  
      windowsFormsHost1.Child = _pnlSched;  
      test.Children.Add(windowsFormsHost1);  
      while (_childp.MainWindowHandle == IntPtr.Zero)  
      {  
        Thread.Yield();  
      }  
      _appWin = _childp.MainWindowHandle;  
      SetParent(_appWin, _pnlSched.Handle);  
    }  
  }  
}
