Can I embed another running exe inside my visual basic form? - vb.net

Question

I started experimenting with embeding another .exe in my form. I managed to run another program and use it inside a forms panel. Is there a way to put inside this panel an already running exe?
Public Class Form1
Declare Auto Function SetParent Lib "user32.dll" (ByVal hWndChild As IntPtr, ByVal hWndNewParent As IntPtr) As Integer
Declare Auto Function SendMessage Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
Dim proc As Process
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
proc = Process.Start("C:\WINDOWS\notepad.exe")
proc.WaitForInputIdle()
SetParent(proc.MainWindowHandle, Panel1.Handle)
End Sub
End Class

The code becomes like this. The notepad.exe needs to be running , on startup it embeds the notepad.exe on the main form. Thanks a lot.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim proc = Process.GetProcessesByName("notepad").FirstOrDefault()
If proc IsNot Nothing Then
SetParent(proc.MainWindowHandle, Panel1.Handle)
End If
End Sub
End Class
