在VC++6.0入门与提高里的鼠标追踪程序，我怎么总是编译不通过？错误如下

[hsghxm]

void CMouseView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
static char output[20];
CMainFrame * pFrame =(CMainFrame *)(AfxGetApp->m_pMainWnd);
CStatusBar * pStatus = &pFrame->m_wndStatusBar;
if(pStatus)
{
sprintf(output,"(%d,%d)",point.x,point.y);
pStatus->SetPaneText(2,output);
}
CView::OnMouseMove(nFlags, point);
}

在“CMainFrame * pFrame =(CMainFrame *)(AfxGetApp->m_pMainWnd);”报错！
--------------------Configuration: Mouse - Win32 Debug--------------------
Compiling...
MouseView.cpp
D:\my_work\C\Mouse\MouseView.cpp(104) : error C2227: left of '->m_pMainWnd' must point to class/struct/union
Error executing cl.exe.

Mouse.exe - 1 error(s), 0 warning(s)

请高手指教，今天刚开始学VC

void CMouseView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
static char output[20];
CMainFrame * pFrame =(CMainFrame *)(AfxGetApp()->m_pMainWnd);
CStatusBar * pStatus = &pFrame->m_wndStatusBar;
if(pStatus)
{
sprintf(output,"(%d,%d)",point.x,point.y);
pStatus->SetPaneText(2,output);
}
CView::OnMouseMove(nFlags, point);
}
原来少了个括号，书上印刷错误了，初学者好倒霉！

都是在错误中成长起来的
