Using color cursors !

How can I use colored cursors in my MFC application ?
I have try this but no cursor are loaded :

IDC_MYCOLORCURSOR is a 16 color cursor defined in the
resource.

BOOL CMyDialog::OnSetCursor(CWnd *pWnd, UINT nHitTest, UINT message)
{
HCURSOR hCursor = LoadCursor(IDC_MYCOLORCURSOR);
if (hCursor) // hCursor is always NULL. Why ?
{
::SetCursor(hCursor);
return TRUE;
}

return CDialog::OnSetCursor(pWnd,nHitTest,message);
}

I have also try this :

static HANDLE g_hCursor;

BOOL CMyDialog::OnInitDialog()
{
......
g_hCursor = LoadImage(AfxGetInstanceHandle(), "IDC_MYCOLORCURSOR", IMAGE_CURSOR, 0, 0, LR_DEFAULTSIZE);
// g_hCursor is always NULL (Also when the cursor is monochrome). Why ?
......
}

BOOL MyDialog::DestroyWindow()
{
if (g_hCursor) DestroyCursor((HCURSOR)g_hCursor);
....
}

BOOL CMyDialog::OnSetCursor(CWnd *pWnd, UINT nHitTest, UINT message)
{
HCURSOR hCursor = (HCURSOR)g_hCursor;
if (hCursor)
{
::SetCursor(hCursor);
return TRUE;
}

return CDialog::OnSetCursor(pWnd,nHitTest,message);
}

I have already test this and it doesn't work !
When I create a color cursor whith the workshop (for example, an 16 colors cursor) and I load this cursor with your method, the cursor never appears.
I must also tell that whith the workshop, when I use for example the red color and then an other color, all colors became black.

How must I proceed to create a color cursor with the workshop of visual C++ 5.0 ?

Create 256 color icon resource with VC.

HCURSOR cursor = (HCURSOR)( AfxGetApp()->LoadIcon(IDI_ICON256) );

SetCursor( cursor );
