The following is the explanation of the functions used above:
BOOL CDC::TextOut(int x, int y, const CString& str);
This function outputs a text string at the specified x-y coordinates. The string is stored in str
parameter. Text color and background color can be set by using functions CDC::SetTextColor(…) and
CDC::SetBkColor(…). Background mode (specifies if text has transparent or opaque background) can be set
by using function CDC::SetBkMode(…).
BOOL CDC::Chord(LPCRECT lpRect, POINT ptStart, POINT ptEnd);
