Hi,

I would like to have a CListCtrl in report mode with columnheader but
I would like the column header to be transparent and without displaying separators.
How can I do that ?

Or same question : HOW CAN I CHANGE COLUMN HEADER COLOR ?
Ok I found it :

//---------------------------------------------------------------------------//
// class CHeaderCtrlEx
//---------------------------------------------------------------------------//
CHeaderCtrlEx::CHeaderCtrlEx()
{

}

CHeaderCtrlEx::~CHeaderCtrlEx()
{

}


BEGIN_MESSAGE_MAP(CHeaderCtrlEx, CHeaderCtrl)
//{{AFX_MSG_MAP(CColorHeaderCtrl)

//}}AFX_MSG_MAP
END_MESSAGE_MAP()

// CHeaderCtrlEx::OnCustomDraw
//

//
void CHeaderCtrlEx::OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult)
{
NMCUSTOMDRAW* pCD = (NMCUSTOMDRAW*)pNMHDR;
DWORD dwDrawStage,
dwItemSpec;

*pResult = CDRF_DODEFAULT;

dwDrawStage = pCD->dwDrawStage;
dwItemSpec = pCD->dwItemSpec;

if(dwDrawStage == CDDS_PREPAINT)
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if(dwDrawStage == CDDS_ITEMPREPAINT)
{
HDC hDC = pCD->hdc;

SetTextColor(hDC, RGB(255, 255, 255));

if(dwItemSpec)
SetBkColor(hDC, RGB( 0, 0, 255)); // Blue
else
SetBkColor(hDC, RGB( 255, 0, 0)); // Red

*pResult = CDRF_NEWFONT;
}
}


// CColorHeaderCtrl::OnEraseBkgnd
//
// This is where we specify the background color of the header
//
BOOL CHeaderCtrlEx::OnEraseBkgnd(CDC* pDC)
{
CRect rc;

GetClientRect(&rc);

pDC->FillSolidRect(&rc, RGB(255, 255, 0)); // Yellow
return TRUE;
}


/////////////////////////////////////////////////////////////////////////////

}

return nRval;
}

void CHistoryListCtrl::PreSubclassWindow()
{
// Use REPORT mode

SubclassHeader();


CListCtrl::PreSubclassWindow();
