我有一个程序，实现视图的分割（分成3个区域），编译时出错，如下：
ewSplitter.obj : error LNK2001: unresolved external symbol "public: virtual struct CRuntimeClass * __thiscall CNewSplitter::GetRuntimeClass(void)const " (?GetRuntimeClass@CNewSplitter@@UBEPAUCRuntimeClass@@XZ)
相关的程序段：
class CNewSplitter : public CSplitterWnd
{
DECLARE_DYNAMIC(CNewSplitter)
public:
CNewSplitter();
virtual ~CNewSplitter();
};


BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
if(!m_wndSplitter.CreateStatic(this,1,2))return FALSE;

CRect rect;
GetClientRect(&rect);
CSize size=rect.Size();
size.cx=size.cx*3/4;

if(!m_wndSplitter.CreateView(0,1,RUNTIME_CLASS(CMyHtmlView),size,pContext))
return FALSE;

if(!m_wndSplitter2.CreateStatic(&m_wndSplitter,2,1,WS_CHILD|WS_VISIBLE|WS_BORDER,
m_wndSplitter.IdFromRowCol(0,0)))return FALSE;

if (!m_wndSplitter2.CreateView(0, 0,
RUNTIME_CLASS(CMyTreeView), CSize(0, lpcs->cy*3/4), pContext))return FALSE;
if (!m_wndSplitter2.CreateView(1, 0,
RUNTIME_CLASS(CMyListView), CSize(0, 0), pContext))return FALSE;

return TRUE;
}
那位高手知道的话，给不才一个解答，先谢谢了！

m_wndSplitter 是CNewSplitter 的实例吗?

看不太清

先将你的debug和release目录都删掉，然后重新进行编译。

m_wndSplitter 是从CSplitterWnd继承下来的！！！
快帮帮我！

说错了，m_wndSplitter 是从CSplitterWnd继承下来的类的实例的！！！
