CPtrList内存泄漏解决

若定义结构体：

struct stColor
{
	int nRow;
	int nCol;
	COLORREF rgb;
	BOOL bSet;
};

且添加

	stColor *pColor  = new stColor;
	pColor->nCol = col;
	pColor->rgb = color;
	pColor->bSet = bSet;
	m_ptrListCol.AddTail(pColor);

若m_ptrListCol不处理，则会存在泄露；需在析构中对其进行处理：

	while(!m_ptrListCol.IsEmpty()) 
		delete(stColor*)(m_ptrListCol.RemoveHead());
	m_ptrListCol.RemoveAll();
