手动创建StaticText控件，应如何设置背景颜色，并实现根据变量改变背景颜色

void CForkliftDlg::CreatFeedbackPoints()

{

	#define MAX_COUNT 15

	CStatic *m_static = new CStatic[MAX_COUNT];        //控件数组

	#define IDC_STATIC1 0x11

	#define MAX_XGAP 5

	#define MAX_YGAP 5

	#define MAX_WIDTH 115

	#define MAX_HEIGHT 35

	#define MAX_LINE 4



	CRect rc(CPoint(30, 580), CSize(MAX_WIDTH, MAX_HEIGHT));

	CString strText(_T(""));

	for (int i = 0; i < MAX_COUNT; i++)

	{

		m_static[i].Create(strText, WS_CHILD | WS_VISIBLE | SS_BLACKFRAME | SS_BLACKRECT, rc, this, IDC_STATIC1 + i);

		m_static[i].SetFont(GetFont());



		if (0 == ((i + 1) % MAX_LINE))

		{

			rc.left = 30;

			rc.right = rc.left + MAX_WIDTH;

			rc.top = rc.bottom + MAX_YGAP;

			rc.bottom = rc.top + MAX_HEIGHT;

		}

		else

		{

			rc.left = rc.right + MAX_XGAP;

			rc.right = rc.left + MAX_WIDTH;

		}

	}
