void CSecProToolDlg::OnNMRclickTreeSoftpro(NMHDR *pNMHDR, LRESULT *pResult)
{
CString str;
//POINT Point;
CPoint OldPoint;
::GetCursorPos(&Point);
OldPoint=Point; CMenu   menu;   
    menu.LoadMenu(IDR_MENU_SOFTPRO); 
CMenu *submenu  =  menu.GetSubMenu(0); m_Tree_SoftPro.ScreenToClient(&Point);
HTREEITEM   hRoot,hParent,hChild;
hRoot=m_Tree_SoftPro.GetRootItem();
CRect Rect;
m_Tree_SoftPro.ScreenToClient(Rect);

while(NULL!=hRoot)
{
m_Tree_SoftPro.GetItemRect(hRoot,Rect,FALSE);
if(Point.x>=Rect.left && Point.x<=Rect.right && Point.y>=Rect.top && Point.y<=Rect.bottom)
{
submenu->EnableMenuItem(IDR_ADD_SOFTTYPE,MF_BYCOMMAND|MF_ENABLED);
submenu->EnableMenuItem(IDR_CHANGE_SOFTTYPE,MF_BYCOMMAND|MF_ENABLED);
submenu->EnableMenuItem(IDR_DELETE_SOFTTYPE,MF_BYCOMMAND|MF_ENABLED);

}

hRoot=m_Tree_SoftPro.GetNextSiblingItem(hRoot);
}
submenu->EnableMenuItem(IDR_ADD_SOFTTYPE,MF_BYCOMMAND|MF_ENABLED);
submenu->TrackPopupMenu(TPM_LEFTALIGN,OldPoint.x,OldPoint.y,this);
*pResult = 0;
}

Answer 2

1.添加NM_RCLICK事件
2.把你自己定义的菜单加载入CMenu的对象。
3.调用TrackPopupMenu（）
