Hey there everyone , I'm new here , not new to OpenGL tho ,

So basically , I've been scratching my head over a problem for the last 3 weeks , basically , everything works good , it's all done right , but ... it doesn't draw anything , I basically copied code from my last working app on this one , but it doesn't work

Not a vertex is drawn , and I'm sure it's not with my code , I suspect GL_GEOMETRY_VERTICES_OUT_EXT , which is set to 0 for my app , I tried another OpenGL app , and it's not set to 0 in most cases , what do you guys think ? Anything related to that variable ?
