[WinCE]关于error LNK2019

部分代码：
testce_llkView.h
public:
        afx_msg void OnMenuFirst();
public:
        afx_msg void OnLButtonDown(UINT nFlags, CPoint point);

testce_llkVies.cpp:
ON_COMMAND(ID_MENU_FIRST, &Ctestce_llkView::OnMenuFirst)
ON_WM_LBUTTONDOWN()

void Ctestce_llkView::OnMenuFirst(void)
{// TODO: Add your command handler code here
        int i,j;
        int temprand;
        CString str;
        CRect  rect;
...
}

void Ctestce_llkView::OnLButtonDown(UINT nFlags, CPoint point)
{int  iTop,iLeft,iRight,iBottom;
        CRect  rect;
...
}

编译后出现：
