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 ?

A stab in the dark as I have not tried this, but how about creating your own
MyHeaderCtrl class derived from CHeaderCtrl class and use an object of this
type on your list control. In your MyHeaderCtrl class, catch the message
that sets the background color - I can't remember what it is, but you would
find it in the MSDN.

Ok I found it :

CHeaderCtrlEx::CHeaderCtrlEx()
{

}

CHeaderCtrlEx::~CHeaderCtrlEx()
{

}

END_MESSAGE_MAP()

{
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 TRUE;
//}






//---------------------------------------------------------------------------//

IMPLEMENT_DYNAMIC(CHistoryListCtrl, CListCtrl)
CHistoryListCtrl::CHistoryListCtrl()

}

END_MESSAGE_MAP()




int CHistoryListCtrl::SubclassHeader()
{
CHeaderCtrl* pHeader;
int nRval = 0;

pHeader = GetHeaderCtrl();
if(pHeader && pHeader->GetSafeHwnd()){
if(!m_hdr.SubclassWindow(pHeader->GetSafeHwnd()))
nRval = -1;
}

return nRval;
}

void CHistoryListCtrl::PreSubclassWindow()
{
// Use REPORT mode
ModifyStyle(0, LVS_REPORT);

//-- Subclassing header with our custom --//
SubclassHeader();


CListCtrl::PreSubclassWindow();
}




//---------------------------------------------------------------------------

int CHistoryListCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)

return -1;

return SubclassHeader();
}

Here is a good article on how to subclass the listctrl's header control.
