Class Description:

    DateTimePicker MFC control wrapper.

Public Interface:

    CDateTimePicker         : Constructor
    ~CDateTimePicker        : Destructor    

    Create                  : Create the control
    GetSystemTime           : Get systemtime struct value from control
    SetSystemTime           : Set control time value from systemtime struct
    GetRange                : Get the min/max time range
    SetRange                : Set the min/max time range
    SetFormat               : Set display formatting string
    GetMonthCalColor        : Get the month calendar colour
    SetMonthCalColor        : Set the month calendar colour

Notes:

    Either create control dynamically with Create method, or put in resource
    template as a user control of name "SysDateTimePick32".  In this case,
    common style DWORDs as follows:

    WS_BORDER | WS_CHILD | WS_VISIBLE     0x50800000

                      DTS_UPDOWN              0x0001
                      DTS_SHOWNONE            0x0002
                      DTS_SHORTDATEFORMAT     0x0000
                      DTS_LONGDATEFORMAT      0x0004
                      DTS_TIMEFORMAT          0x0009
                      DTS_APPCANPARSE         0x0010
                      DTS_RIGHTALIGN          0x0020

    Time and date format changes are automatically picked up by the control
