   Public EditingCode As Boolean = False
   Public CurrentCodeValue As String = ""
   Public HoverCodeValue As String = ""
   
   Public lastMouseState As MouseState
   Private vscroll As System.Windows.Forms.VScrollBar
   Private hscroll As System.Windows.Forms.HScrollBar 

3. Add the following lines to the Game1 constructor:

   vscroll = CType(parentForm.Controls("VScrollBar1"),System.Windows.Forms.VScrollBar)
   
   hscroll =CType(parentForm.Controls("HScrollBar1"),System.Windows.Forms.HScrollBar)

4. Modify the LoadContent() method of the Game1 class to read:

     Camera.ViewPortWidth = pictureBox.Width
     Camera.ViewPortHeight = pictureBox.Height
     Camera.WorldRectangle =New Rectangle(
