    how to draw a hexagon?

    hey there, im trying to make an application that will create a hex-map (essentially a grid map where each cell is a hexagon instead of a square).... im not really sure where to start with this, but i figured that the best place to start would be one single cell.... is hexagon an object that is supported already? ie. does the system.drawing allow for hexagons to be drawn

    call DrawPolygon and pass in the 6 points needed to draw your shape.

    you can always create helper methods to do things like drawing a hexagon that wrap the lower level api's, and make your life a little easier.

    Change count to 6 and draw a line...
    Code:
    Private Sub Form_Load()
      Dim px As Double, py As Double, i%, cnt%, r1 As Double, r As Double
      px = ScaleWidth / 2 - Text1(0).Width / 2
      py = ScaleHeight / 2 - Text1(0).Height / 2
      r = 1365    ' radius
      cnt = 12    ' number of images
      Text1(0).Move px, py
      Text1(0).Visible = False
      For i = 1 To cnt
        If Not i = 0 Then Load Text1(i)
        With Text1(i)
           r1 = 360 / cnt * (i) * 3.1428571 / 180
          .Move px + r * Sin(r1), py - r * Cos(r1)
          .Text = i
          .Visible = True
        End With
    Next i
    End Sub
    This draws numbers on a clock face

    Why VB6 code in response to a question posted in the C# section?

    Re: how to draw a hexagon?

    MadHatter is correct about the DrawPolygon method - that's what I would have done as well. I prefer to make use of the .NET classes as much as possible, instead of API ( although they can be extremely handy ), I guess it's just a matter of opinion

    Here is a very nice example to get you started with drawing Hexagons, only issue I have with this article is the fact that it's not a CG one !

    I hope my post was useful, if even a little
