Open window application from another

Hello Patel, Added panel inside the form and opening another app inside panel.

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
//using System.Threading;
using System.Windows.Forms;
namespace RunAnotherAppWithinMyApp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
private void button1_Click(object sender, EventArgs e)
{
Process p = Process.Start("notepad.exe");
//Thread.Sleep(200); // Allow the process to open it's window
p.WaitForInputIdle(); // Allow the process to open it's window
SetParent(p.MainWindowHandle, panel1.Handle);
}
}
}

Below is designer code:

namespace RunAnotherAppWithinMyApp
{
partial class Form1
{
///
/// Required designer variable.
///
private System.ComponentModel.IContainer components = null;
///
/// Clean up any resources being used.
///
/// true if managed resources should be disposed; otherwise, false.
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
///

/// the contents of this method with the code editor.

private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.panel1 = new System.Windows.Forms.Panel();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(23, 12);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(220, 34);
this.button1.TabIndex = 0;
this.button1.Text = "Open Another App";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// panel1
//
this.panel1.Location = new System.Drawing.Point(23, 52);
this.panel1.Name = "panel1";
this.panel1.Size = new System.Drawing.Size(751, 386);
this.panel1.TabIndex = 1;
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(10F, 25F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(800, 450);
this.Controls.Add(this.panel1);
this.Controls.Add(this.button1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Panel panel1;
}
}
