Could you get that working with PolyPolygon instead of only Polygons ?...
well increase the points if its possible... i cant seem to get it working
i tried this code

    Me.AutoRedraw = True
    Dim vertex(0 To 6) As POINTAPI ' holds vertices of each polygon
    Dim numvertices(0 To 1) As Long  ' holds how many vertices belong to each polygon
    Dim hRgn As Long  ' handle to the multi-polygonal region
    Dim retval As Long  ' return value

    ' Load the vertices of the triangle into the vertex array.
    vertex(0).x = 25: vertex(0).y = 25  ' 1st point: (25,25)
    vertex(1).x = 50: vertex(1).y = 50  ' 2nd point: (50,50)
    vertex(2).x = 25: vertex(2).y = 50  ' 3rd point: (25,50)
    numvertices(0) = 3  ' three vertices for the triangle

    ' Load the vertices of the diamond into the vertex array.
    vertex(3).x = 150: vertex(3).y = 150  ' 1st point: (150,150)
    vertex(4).x = 200: vertex(4).y = 200  ' 2nd point: (200,200)
    vertex(5).x = 150: vertex(5).y = 250  ' 3rd point: (150,250)
    vertex(6).x = 100: vertex(6).y = 200  ' 4th point: (100,200)
    numvertices(1) = 4  ' four vertices for the triangle
    hBrush = CreateSolidBrush(RGB(255, 126, 25))
    ' Create the multi-polygonal region and get a handle to it.
    hRgn = CreatePolyPolygonRgn(vertex(0), numvertices(0), 2, ALTERNATE)

    ' If the creation of the region was successful then color.

    If hRgn Then FillRgn Me.hdc, hRgn, hBrush

    DeleteObject hRgn

It also need to fill and outline... the other one worked GREAT...

It works, maybe you forget to put the Command buttons ? (Command1, Command2, Command3)

Need to draw them not make the form like it, i need to fill them and outline them

Thanks, increased the point for this one

then you may need to use FillRgn to fill the region with the colors, see my first post example?

and err... sorry, what is mean by drawing the outline ? Is that mean to draw the sides of the polygon with a Line?

regards

Could you please create an example i have been trying for ages and i simple cant get it to fill the region..

And yes i need a line around the PolyPolygon

Hi mSchmidt,

I will post it by tomorrow, now is 1.04AM at my local time, cheers

Try this out :)

Great solution ryancys, love it...
i opened a new question on how to add text, if you have any ideas i would be happy
