VB.NET Usage

Sub DrawPoint(x As Double, y As Double, pixelSize As Integer, color As System.UInt32)

            Parameters

x

The x coordinate of the point to draw.
y The x coordinate of the point to draw.
pixelSize The size in pixels of the point to be drawn.
color The color of the point to be drawn. This is a UInt32 representation of an RGB color.

Sample Code

    Private Sub DrawPoint()
        Dim draw_hndl As Integer, size As Integer
        Dim x1 As Double, y1 As Double
        'Set point as x = 100, y = 100
        x1 = 100
        y1 = 100
        'Set pixel size for point
        size = 5
        'Create new drawing layer on map
        draw_hndl = Map1.NewDrawing(MapWinGIS.tkDrawReferenceList.dlScreenReferencedList)
        'Draw black point on map
        Map1.DrawPoint(x1, y1, size, System.Convert.ToUInt32(RGB(0, 0, 0)))
    End Sub
  

VB 6 Usage
Sub DrawPoint(x As Double, y As Double, pixelSize As Long, color As OLE_COLOR)
            Parameters

x

The x coordinate of the point to draw.
y The x coordinate of the point to draw.
pixelSize The size in pixels of the point to be drawn.
color The color of the point to be drawn.

Sample Code

    Private Sub DrawPoint()
        Dim draw_hndl As Long, size As Long
        Dim x1 As Double, y1 As Double
        'Set point as x = 100, y = 100
        x1 = 100
        y1 = 100
        'Set pixel size for point
        size = 5
        'Create new drawing layer on map
        draw_hndl = Map1.NewDrawing(MapWinGIS.tkDrawReferenceList.dlScreenReferencedList)
        'Draw black point on map
        Map1.DrawPoint x1, y1, size, RGB(0, 0, 0)
    End Sub
