Question

I am trying to write an application to visualize shapefile on a .net form without using any external SDK. I have successfully written the code to read a shapefile. Now I am unable to get the GDI+ trick to draw the geometries to the user control effectively.

Any idea?

You should use Graphics object of a UserControl( generally a Control ) to draw points, lines, etc on it. This will be useful if you can obtain point information from shapefile. Use following links to make it work.
Drawing with Brush on UserControl and
Drawing a Point on a Custom UserControl

This is an example :

Graphics g = this.CreateGraphics();
g.DrawPolygon( ... ) ;
