====== A VO GUI application with a Windows Forms window ======

Thanks to the work of Paul Piko there is the possibility to add a WinForms to a VO GUI application.

These are the steps:
  * Instead of using the "normal" App class from the VO GUI classes use the VOWinFormApp class (contained in the X# VO GUI classes window)
<code visualfoxpro>[STAThreadAttribute];
function Start( asCmdLine as string[] ) as int
  local oMainWindow as StandardShellWindow
  local oApp as VOWinFormApp // App

  oApp := VOWinFormApp{} // App{}

  oMainWindow := StandardShellWindow{oApp}
  oMainWindow:Show(SHOWCENTERED)

  oApp:Exec()

  return 0</code>
  * when opening your Windows Forms window, use a ChildWinForm object as owner:
<code visualfoxpro>local oForm as MyWinForm
  local oChild as ChildWinForm

  oChild := ChildWinForm{ self, true }
  oChild:Menu := StandardShellMenu{ oChild }
  oForm := MyWinForm{ oChild }
  oChild:WinForm := oForm
  oChild:Show()</code>
  * when you need to close your Windows form, call the :EndWindow() method of your ChildWinForm owner object:
<code visualfoxpro>method CloseButtonClick(sender as System.Object , e as System.EventArgs) as void

  _oOwner:EndWindow()
  return</code>
 
You can find a sample of such an application here (in form of a XIDE export file):
