Is there a routine to fill a polygon (other than the predefined shapes like triangle, circle) with a color? Example: in a state map, borders of individual states are defined by set of X/Y coordinates forming an irregular polygon.

Place this code in the Declarations section:
Private Declare Function ExtFloodFill Lib "gdi32" (ByVal hdc As Long, ByVal X As Long, ByVal Y As Long, ByVal crColor As Long, ByVal wFillType As Long) As Long

The following procedure will fill the area from the point specified in the color specified:
Private Sub FillArea(X As Long, Y As Long, lColor As Long)
  Dim lOldColor As Long
  Dim lFillType As Long
  Dim lRes      As Long
  Const FLOODFILLBORDER = 0  ' Fill until lColor color encountered.
  Const FLOODFILLSURFACE = 1 ' Fill surface until lColor color not
                             ' encountered.
  Picture1.FillColor = lColor
  lOldColor = Picture1.Point(X, Y)
  lFillType = FLOODFILLSURFACE
  lRes = ExtFloodFill(Picture1.hdc, X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY, lOldColor, lFillType)
End Sub
