If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Help me to understand what I'm saying, and I'll explain it better to you

Make sense?

graphics.DrawImage(background, 0, 0, rect.left, rect.top, rect.right, rect.bottom, UnitPixel);
graphics.DrawImage(&knobImages, 0, 0, 0, knobPosition * KNOB_HEIGHT, KNOB_WIDTH, KNOB_HEIGHT, UnitPixel);
