Winforms keeping a dialog open but hidden

You can keen a windows form open but hidden bringing it into focus on demand as follows:

• Declare it in your main class

RFCManager rfcmanager;

• create it in on form load:

rfcmanager = new RFCManager();
rfcmanager.Hide();

• When you want to show:
  

rfcmanager.Show();

• On the FormClosing Event handler :

this.Hide();
e.Cancel = true;


Enjoy!
