drawing circles and placing values next to circle

[Ranjit]

Hi,
I would like to know how to place circles in the
connecting points of the lines, and very close to the
circles I would like to place the values like a,b,c...etc
automatically for each connecting point on the line.
I meant connecting points like.
Here I shall explain my requirements clearly thro' my
coding:

Private Sub Button1_Click(B yVal sender As System.Object,
ByVal e As System.EventArg s) Handles Button1.Click
On Error Resume Next
For i = 0 To 1246
x1 = Val(rs.Fields(" Easting").Value )
y1 = Val(rs.Fields(" Northing").Valu e)
pt = New Point(x1, y1)
rs.MoveNext()
x2 = Val(rs.Fields(" Easting").Value )
y2 = Val(rs.Fields(" Northing").Valu e)
pt2 = New Point(x2, y2)
ogra = Me.CreateGraphi cs
ogra.DrawLine(P ens.Blue, myconversion(pt ),
myconversion(pt 2))
'ogra.DrawEllip se(penprocs, myconversion(pt 2),
5, 5)
Next
rs.Close()
End Sub

Private Function myconversion(By Val temp As Point) As Point
Return New Point(temp.X, ClientSize.Heig ht -
temp.Y)
End Function

If you notice my button_click

ogra.drawellips e line is commented because it was giving
me an error.It's design time error but I cant sort out my
problem.
Actually in this case at every end point of the line I
need to place the circle.I have continous n number of
lines,in that from where on my line is continuing I want
to place the circle and place the continous alphabets like
a,b,c automatically just on top or very close to my
circle.
