I have the following code which dynamically creates CStatic labels.

[Code]
While(i < 5)
CRect textrect(44,y,110,y+5);
CStatic *text = new CStatic ;
MapDialogRect(&textrect);
text -> Create ( msgs.data(),WS_CHILD | WS_VISIBLE | SS_ LEFT , textrect,this ,0);
[/ Code]

If you are going to handle color and erase messages with regard to painting the control, then you should also handle the WM_PAINT message for adding the text.

Look for a class at this site called CLabel. It is an owner-drawn replacement control for CStatic. With it, you can set the foreground color, background color, and text font to use for the control. It is very handy and I use it often.

1. ON_WM_CTLCOLOR_REFLECT
2. ON_WM_ERASEBKGND
3. ON_WM_PAINT

example:

C++

HBRUSH CColorStatic::CtlColor(CDC* pDC, UINT nCtlColor)
{
	pDC->SetBkMode(TRANSPARENT);
	if(m_nPos != -1)
		pDC->SetTextColor(DEF_TEXTCOLOR);
	else
		pDC->SetTextColor(m_TextColor);
	return (HBRUSH)::GetStockObject(NULL_BRUSH);
}

BOOL CColorStatic::OnEraseBkgnd(CDC* pDC)
{
	return TRUE;
}

void CColorStatic::OnPaint()
{
	CRect		Rect;
	CPaintDC	dc(this);
	TCHAR		szText[1024];
	CFont		*pFont, *pOldFont;
	int			w1, w2;

	GetWindowText(szText, sizeof(szText)/sizeof(TCHAR));
	GetClientRect(Rect);

	if(m_nPos == -1)
	{
		dc.FillSolidRect(0, 0, Rect.Width(), Rect.Height(), m_BackColor);
		dc.SetTextColor(m_TextColor);
	}
	else
	{
		w1 = Rect.Width() * m_nPos / m_nPosMax;
		w2 = Rect.Width() - w1;
		dc.FillSolidRect(0, 0, w1, Rect.Height(), m_TextColor);
		dc.FillSolidRect(w1, 0, w2, Rect.Height(), m_BackColor);
		dc.SetTextColor(DEF_TEXTCOLOR);
	}

	dc.SetBkMode(TRANSPARENT);
	pFont = GetFont();
	pOldFont = dc.SelectObject(pFont);
	dc.DrawText(szText, _tcslen(szText), Rect, DT_CENTER | DT_VCENTER | DT_SINGLELINE);
	pOldFont = dc.SelectObject(pOldFont);
}
