The Calendar Control

The

MSCal.ocx control is a popular ActiveX calendar control that's probably already installed and registered on your computer. If it isn't there, don't worry. It's on the companion CD.

Figure 9-1 shows the calendar control inside a modal dialog box.

Figure 9-1: The calendar control in use.

The calendar control comes with a help file that lists the control's properties, methods, and events, as shown in Table 9-1.

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.
