在线求助？？？为什么有内存溢出

[yongxinwork]

void CMouseMoveTestView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
#ifdef _DEBUG
CMemoryState oldMemState,
newMemState, diffMemState;
oldMemState.Checkpoint();
#endif

//Set Coord Panel

CPoint pt = point;
/* CClientDC dc(this);
OnPrepareDC(&dc);
dc.DPtoLP( &pt );*/

//!下面是一个错误！???????????????????????????????????


CMainFrame* pMainFrame = (CMainFrame*) AfxGetMainWnd();
// pMainFrame->SetCoordPanel( ptLP );
// pMainFrame->SetCoordPanel( pt );

int id = pMainFrame->m_wndStatusBar.CommandToIndex( ID_COORDPANEL );
if(id<0)
AfxMessageBox("asd");
CString m_strCoord;
m_strCoord.Format( "%d, %d", pt.x, pt.y );
//!这句话有内存溢出
pMainFrame->m_wndStatusBar.SetPaneText( id, m_strCoord);

#ifdef _DEBUG
newMemState.Checkpoint();
if(diffMemState.Difference(oldMemState, newMemState)) {
TRACE("Difference between first and now!\n\n");
diffMemState.DumpStatistics();
ASSERT(FALSE);

}
#endif

CView::OnMouseMove(nFlags, point);
}

pMainFrame

这个指针得到的对么？

CMainFrame* pMainFrame = (CMainFrame*) AfxGetMainWnd();

我怀疑是这个的错误！

根据CMouseMoveTestView

你试着把CMainFrame改为CMouseMoveTestFrame试试。

[yongxinwork]

这句话没有错
CMainFrame* pMainFrame = (CMainFrame*) AfxGetMainWnd();

如果有错，下面这句就有错了！
int id = pMainFrame->m_wndStatusBar.CommandToIndex( ID_COORDPANEL );
if(id<0)
AfxMessageBox("asd");

问题找到了！谢谢大家
你们看看下面调试就知道什么原因了，是CString 的原因！！！！！
void CMouseMoveTestView::OnTest()
{
// TODO: Add your command handler code here
#ifdef _DEBUG
CMemoryState oldMemState,newMemState, diffMemState;
oldMemState.Checkpoint();
#endif

//Set Coord Panel
// CPoint pt = point;
CString m_strCoord="";
m_strCoord.Format("%d,%d", 12,30);

#ifdef _DEBUG
newMemState.Checkpoint();
if(diffMemState.Difference(oldMemState, newMemState)) {
TRACE("Difference between first and now!\n\n");
diffMemState.DumpStatistics();
ASSERT(FALSE);

}
#endif
}
