使用CArray遇到调试错误

自己写的代码

CArray<int,int &> CPlotChartControl::GetXSeletedIndexs(void)
{
	double scaleX = m_rectPlot.Width() / (m_xAxis.fMax - m_xAxis.fMin);
	double fxL ;
	int max=m_curSelectRect.right;
	int min=m_curSelectRect.left;
	for(int i=0;i<m_nLen;i++)
	{ 
        fxL = m_rectPlot.left+(m_pXData[i] - m_xAxis.fMin) *scaleX ; 
		if(fxL>min&&fxL<max)
			m_selectPointXIndexs.Add(i);
	}
	return m_selectPointXIndexs;

请大神帮忙

CArray<int,int &>  ->CArray<int,int>

你的 m_selectPointXIndexs怎么定义的

CArray<int,int &> m_selectPointXIndexs;// 选取频率的X轴索引 这样定义的

i的类型不是int &

??具体可以怎么修改？？

CPoint MaximaPoint;
				MaximaPoint.x = static_cast<int>(m_rectPlot.left + (m_pXData[j] - m_xAxis.fMin) * scaleX);
				MaximaPoint.y = static_cast<int>(m_rectPlot.bottom - (m_pYData[j] - m_yAxis.fMin) * scaleY);
				
				if(!m_selectPointVIndex.IsEmpty())   //查看m_selectPointVIndex是否有重复的索引号
				{
					bool bflags = false;             
					for(int k=0; k<m_selectPointVIndex.GetSize(); k++)
					{
						if(j == m_selectPointVIndex.GetAt(k))
							bflags = true;
					}
					if(bflags)    //有重复序号
						;
					else          //没有重复序号
					{
						m_selectPoint.Add(MaximaPoint);
				        m_selectPointVIndex.Add(j);
					}
				}
				else             //第一次选取的点
				{
					m_selectPoint.Add(MaximaPoint);   //存极值的点坐标
				    m_selectPointVIndex.Add(j);       //存极值点的索引号
				}			
				Invalidate();
			}	

别人程序也这样编译没问题

测试了一下，不会出错
	CArray<int,int &> m_selectPointXIndexs;
	for (int i=1 ;i <3;i++)
	{
		m_selectPointXIndexs.Add(i);
	}

头疼，之前运行没错，后来写了一个函数，运行就有问题，现在把函数取消，还是没用

CArray The CArray class supports arrays that are similar to C arrays, but can dynamically shrink and grow as necessary. template< class TYPE, class ARG_TYPE > class CArray : public CObject At a Glance Header file: Afxtempl.h Platforms: Versions: 1.0 and later Complete documentation: Visual C++ documentation See Also CArray Member Functions, CArray Operators, CObArray CArray::Add int Add( ARG_TYPE newElement ); throw( CMemoryException ); Return Value The index of the added element. Parameters ARG_TYPE Template parameter specifying the type of arguments referencing elements in this array. newElement The element to be added to this array. Remarks Adds a new element to the end of an array, growing the array by 1. If SetSize has been used with an nGrowBy value greater than 1, then extra memory may be allocated. However, the upper bound will increase by only 1. Example // example for CArray::Add CArray<CPoint,CPoint> ptArray; CPoint pt(10,20); ptArray.Add(pt); // Element 0 ptArray.Add(CPoint(30,40)); // Element 1 CArray Overview | Class Members | Hierarchy Chart See Also CArray::SetAt, CArray::SetAtGrow, CArray::InsertAt, CArray::operator []

一个成员变量 干嘛把他整成返回值 我就从来没这么用过

返回 CArray 需要拷贝构造函数， 而 CArray 基于 CObject。 CObject 禁止的。 她的 拷贝构造函数是私有的。
