You'll be using the BackColor, Day, Month, Year, and Value properties in the Ex09a example later in this chapter. BackColor is an unsigned long, but it is used as an OLE_COLOR, which is almost the same as a COLORREF. Day, Month, and Year are short integers. Value's type is the special type VARIANT, which is described in Chapter 25. It holds the entire date as a 64-bit value.Each of the properties, methods, and events listed in the table has a corresponding integer identifier. Information about the names, types, parameter sequences, and integer IDs is stored inside the control and is accessible to Visual Studio .NET at container design time.
