   draw circle and  direct x
  I want to draw a very simple circle using directx 9.I have tried a few things I have found online but no luck.  I also need to know if the following command is correct.D3DXVector3 pos (float x, float y, 0);I am still learning directx 9.   
  I don't think you've looked hard enough. :-Phttp://lmgtfy.com/?q=How+to+draw+a+circle+in+directx+9   ;  I need to know how to draw a circle to the screen using direct x9. I found some code that might work.#define PI 3.14159ffloat radius = 20.0f;float smoothness = 0.05f;float center_x = 400.0f;float center_y = 300.0f;for(float angle = 0.0f; angle <= (2.0f * PI); angle += smoothness){float x = center_x + (radius* (float) sin (angle));float y = center_y + (radius* (float) cos (angle));}However I need to know the direct x command that actually prints to the screeen.   ;  See this tutorial, it explains how to draw the vertices you create for your circle: Tutorial 2: Rendering Vertices.
