这段东西哪里错了？

[naixi]

程序编译通过，执行的时候发生错误，再调试弹出个框框说有个断点在0x409ab5
估计后面算面积的没错，是中间模板的错误
void CMyHomeworkView::GetRgnArea()
{
area1=0;
int i,j;
CRect rect;
CPoint* m_points;
int m_nPoints;
m_nPoints=0;
CMyHomeworkDoc* pDoc = GetDocument();

CTypedPtrList<CObList,CStroke*>& strokeList = pDoc->m_strokeList;
POSITION pos = strokeList.GetHeadPosition();
while (pos != NULL)
{
CStroke* pStroke = strokeList.GetNext(pos);
m_nPoints = m_nPoints+m_pStrokeCur->m_pointArray.GetSize();
}
m_points = new CPoint[m_nPoints];

CTypedPtrList<CObList,CStroke*>& strokeList1 = pDoc->m_strokeList;
POSITION pos1 = strokeList1.GetHeadPosition();
while (pos1 != NULL)
{
CStroke* pStroke1 = strokeList1.GetNext(pos1);
for(i = 0; i<m_nPoints ; i++)
m_points[i] = m_pStrokeCur->m_pointArray[i];
}

CRgn rgn;
rgn.CreatePolygonRgn(m_points, m_nPoints, ALTERNATE);
rgn.GetRgnBox(&rect);

CPoint point;
for( i = rect.top ; i<rect.bottom;i++)
{
for( j = rect.left; j<rect.right ; j++)
{
point.x = j; point.y = i;
if(rgn.PtInRegion(point))
area1 ++;
}
}
delete[] m_points;
}

CTypedPtrList<CObList,CStroke*>& strokeList1 = pDoc->m_strokeList;
POSITION pos1 = strokeList1.GetHeadPosition();
int index = 0;
while (pos1 != NULL)
{
CStroke* pStroke1 = strokeList1.GetNext(pos1);
for(i = 0; i<m_pStrokeCur->m_pointArray.GetSize();i++)
m_points[index++] = m_pStrokeCur->m_pointArray[i];
}

[naixi]

还是错Y
老是说afxtempl第262行错

[yu_hl]

跟踪一下这段代码，看哪句错。

[naixi]

跟踪吗？。。。。。没学过
262行是这个：
{ ASSERT(nIndex >= 0 && nIndex < m_nSize);
我想是不是数组的个数的问题？

[naixi]

小南海，我知道错误了，呵呵，分漫漫给你，如果有问题我接着问，等我弄好了就揭贴

[yu_hl]

你原来的程序数组越界。
倒，变量用的混乱。:(

CTypedPtrList<CObList,CStroke*>& strokeList = pDoc->m_strokeList;
POSITION pos = strokeList.GetHeadPosition();
while (pos != NULL)
{
CStroke* pStroke = strokeList.GetNext(pos);
m_nPoints = m_nPoints+pStroke ->m_pointArray.GetSize();
}
m_points = new CPoint[m_nPoints];

POSITION pos = strokeList.GetHeadPosition();
int index = 0;
while (pos1 != NULL)
{
CStroke* pStroke = strokeList.GetNext(pos);
for(i = 0; i<pStroke->m_pointArray.GetSize();i++)
m_points[index++] = pStroke ->m_pointArray[i];
}

[xqing157]

m_pStrokeCur是什么东西？

[xqing157]

CStroke* pStroke = strokeList.GetNext(pos);
m_nPoints = m_nPoints+m_pStrokeCur->m_pointArray.GetSize();

pStroke和m_pStrokeCur什么关系啊，不懂（水平有限）

小男孩，我也发觉了呀，和你修改的差不离了，多谢
