I've seen the GDI sample, they remind me of the pen up and pen down commands of logo, which i never was a fan of..
You mean turtle graphics? Whats wrong with them?
I had to learn logo at school while i had at home an MSX in those days (which was graphically way more advanced).
It might be something else too, i never like penwidth or patern fills, i like 32bit collors when they where available.
ANYWAY i found something COOL Its called
BASIC4GL (google for their wiki space and download it from there, the main site seams to be offline).
A basic compiler with openGL language support, the basic isnt as advanced as vb6 or vb.net, but it does do fast openGL...
So now i can experimenting drawing in OpenGL before i write somekind .net program to get familiar with openGL.
