Mouse 'control' prob in OpenGL

Hey, Im currently trying to add some mouse control support for my 3rd person camera system. I have used glutPassiveMotionFunc to get the position and when it move it left or right it rotates the view as required. How, its a bit jumpy because it only seems to pickup on the position of the mouse when its moved. Its also hard to control. Its kinda hard to explain...

anyway, I was wondering if there is like a set cursor position function or a similar method to capture the mouse so that it gets set to the middle all the time to improve the control of the mouse. No DirectX though please. Just OpenGL stuff. Thankyou.

#define SCREEN_WIDTH 1024
#define SCREEN_HEIGHT 768

static float MiddleX = SCREEN_WIDTH / 2;
static float MiddleY = SCREEN_HEIGHT / 2;
POINT MousePos;
GetCursorPos(&MousePos); //get current position
SetCursorPos(MiddleX, MiddleY); //put back to middle

it won't let my scene load when i use that. I get a blank screen with my mouse stuck. However, i will have a play and see what i can do. Thank you :)

#include <windows.h>

EDIT:
Post some source I can look at

I have windows.h included. But i still have problems.

Hers some code for the glutPassiveFunc call back function

Code:

---

void mouse(int iX, int iY)
{
if(iX<(SCREEN_WIDTH/2))
        iX=-((SCREEN_WIDTH/2)-iX);
else
        iX=(iX-(SCREEN_WIDTH/2)); // used to convert from top left origin to middle

cCamera.MouseAngleX=180.0*iX/SCREEN_WIDTH;

MouseMoveView();

glutPostRedisplay();
}

---

and the camera function

Code:

---

void MouseMoveView(void)
{
float fMouseX=cCamera.MouseAngleX, fAngleY=0.0f;
int iMidPointX=SCREEN_WIDTH/2, iMidPointY=SCREEN_HEIGHT/2;       
       
if(fMouseX==iMidPointX)
        return;

// GetCursorPos(&MousePos); //get current position. not currently needed as cCamera.MouseAngleX gets it
SetCursorPos(iMidPointX, iMidPointY);
cCamera.MouseAngleX=iMidPointX;        // Set the mouse to the middle                                               

if(fMouseX>cCamera.MouseAngleX)        // Get the direction from the mouse
        fAngleY=-(fMouseX-iMidPointX)/1000;
if(fMouseX<=cCamera.MouseAngleX)
        fAngleY=(fMouseX-iMidPointX)/1000;

//printf("\n%.2f %.2f", fAngleY, fMouseX);

RotateView(&cCamera.vView, fAngleY, 0, 1, 0);
}

I'm not sure what is wrong with your code, it seems messy to me. I'm just going to tell you the order I did things, as I don't feel like debugging right now.

1) get the amount the mouse position moved in X and y directions
2) set back to middle
3) convert to radians
4) rotate vectors radians number of degrees about Y and Strafe
