The code uses GDI+ to draw the stars. That means that if you are in design-mode of the control it will look blank. Are you you using it correctly? What you should first do is open my project, and compile it. That will generate a dll which you can then import into your project by right clicking on the control toolbox and choosing select controls. From there you search for the dll in the dialogue.

Sorry for the short reply I'm using my phone. Let me know if you have any other problems, I will get back to you.
