写得规范些，尽量别有错误。

Answer 1

#define IDM_BLUE 5003
#define IDM_GREEN 5002
#define IDM_YELLOW 5004

//WM_CONTEXTMENU消息是在接到WM_RBUTTONUP消息后，由缺省的Windows进程产生
void CSDITestView::OnContextMenu(CWnd* pWnd, CPoint point)
{
CMenu menuPopup; //新建CMenu对象，

if(menuPopup.CreatePopupMenu()) //调用CreatePopupMenu函数将CMenu对象初始化为弹出式菜单
{
//AppendMenu参数：1.菜单风格标识值，2.新菜单项的命令ID，3.指向字符串的指针(缺省为NULL，分隔符)
menuPopup.AppendMenu(MF_STRING,ID_VIEWCOLOR,"颜色(&R)");

//InsertMenu参数：1.菜单项索引或命令ID，2.风格标识(指明第1个参数的意义)
menuPopup.InsertMenu(0,MF_BYPOSITION|MF_STRING,IDM_GREEN,"&Green");
menuPopup.AppendMenu(MF_SEPARATOR);
menuPopup.AppendMenu(MF_STRING|MF_CHECKED,IDM_BLUE,"&Blue");
menuPopup.AppendMenu(MF_STRING|MF_MENUBARBREAK,IDM_YELLOW,"&Yellow");
menuPopup.TrackPopupMenu(TPM_LEFTALIGN,point.x,point.y,this);
}
}
