解决unhandled exception:java.lang.Exception 解决unhandled exception:java.lang.Exception 阅读详情

大体代码如下：
class CMainFrame : public CFrameWnd
{
protected: // create from serialization only
CMainFrame();
DECLARE_DYNCREATE(CMainFrame)

// Attributes
public:
SplitterWnd wndSplitter;
..........
};
void CMainFrame::Onsend()
{
// TODO: Add your command handler code here
//MessageBox("hello");
SplitterWnd &sw=wndSplitter;
sw.ChangeView(0,1,RUNTIME_CLASS(CRecsms));
}
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
if (!wndSplitter.CreateStatic(this, 1, 2)) return false;
................
}
void SplitterWnd::ChangeView(int row, int col,CRuntimeClass* pViewClass)
{
ASSERT(pViewClass->IsDerivedFrom(RUNTIME_CLASS(CView)));

CView* pView = STATIC_DOWNCAST(CView, GetPane(row, col));
CFrameWnd* pFrame = pView->GetParentFrame();
ASSERT(pFrame);

// set up create context to preserve doc/frame etc.
CCreateContext cc;
memset(&cc, 0, sizeof(CCreateContext));
cc.m_pNewViewClass = pViewClass;
cc.m_pCurrentDoc = pView->GetDocument();
cc.m_pNewDocTemplate = cc.m_pCurrentDoc ?
cc.m_pCurrentDoc->GetDocTemplate() : NULL;
cc.m_pCurrentFrame = pFrame;

DeleteView(row, col); // delete old view

VERIFY(CreateView(row, col, // create new one
pViewClass,
CSize(0,0), // will fix in RecalcLayout
错误发生处： &cc));
// delete &cc;
RecalcLayout(); // recompute layout

// initialize the view
CWnd* pWnd = GetPane(row, col);
if (pWnd)
pWnd->SendMessage(WM_INITIALUPDATE);
}
我把窗口分割成左右两个，通过void CMainFrame::Onsend() 切换右边视图窗口，其中SplitterWnd::ChangeView(int row, int col,CRuntimeClass* pViewClass)是从另外的工程复制过来的，并且在那里运行良好。为什么在我这里运行到“错误发生处：”就出现
Unhandled exception in 文件名.exe(MFC42D.DLL):0x0000005 Access Violation?有什么办法可以解决？谢谢先！！
