making a window scroll

[zwA4jE8b]

I have a function that draws a sine wave.

I would like to make the window 'scroll' so the wave appears to be moving across the screen.

Can anyone give me some example for making a window scroll, or point me in the direction of a good tutorial.

void wavefunc(HDC hDC)
{
	static int _x = 0;
	int _y;
	_y = sin(_x/50.0)*100 + 300;
	SetPixel(hDC, _x, _y, blue);
	_x += 1;
}

Thank you,
Mike
