Form navigation?

Question

Hey all what im trying to do is have a button that when clicked brings up a new form for the using to enter information on it. I did this with the following code. this.Visible=false; frmNewProject newProject = new frmNewProject(); newProject.Show(); What i need to know is how do i go back to my Main form now without creating a new instance of it. When i do frmMain. i can only access a few of its properties like active form i cant use the enabled or visible properties or use the show meathod. Thx in advance, Ryan.
