Hi, I want to paint a CExtResizableDialog derived dialog, but my OnPaint() does not work.


class CSPSSelection:public CExtNCW < CExtResizableDialog>
{
.......
    // Generated message map functions
    //{{AFX_MSG(CSPSSelection)
    afx_msg void OnPaint();
.......
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    //}}AFX_MSG
    DECLARE_MESSAGE_MAP()

}


BEGIN_MESSAGE_MAP(CSPSSelection, CDialog)
    //{{AFX_MSG_MAP(CSPSSelection)
.......
    ON_WM_CREATE()
    ON_WM_PAINT()
    //}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CSPSSelection message handlers
void CSPSSelection::OnPaint()
{
    CPaintDC dc(this);                        // device context for painting

    //1st fill background
    COLORREF colorBK=RGB(0,0,0);
    CBrush bkbrush;
    CRect rect;
    GetClientRect(&rect);
    bkbrush.CreateSolidBrush( colorBK);
    CDC::FromHandle(dc)->FillRect(    &rect,&bkbrush);    
}


How to make it work, and how to paint a CExtResizableDialog after apply skin?

Thanks

Please replace the CPaintDC class with CClientDC:

CPaintDC dc(this);
