Date Tools
 Please note that a
PD 1-Touch Date Tools, a major upgrade, replaces the DLL versions
with the release of Clarion6. This rewrite includes a number of new
classes, templates, and source code not included in PD Date Tools which
has been provided as DLL and LIB files through Clarion 5.5.
ProDomus Date Tools provides developers with a full range of easily
implemented internationalized date and scheduling functions.
Features
Date Scrolling. With an array of alerted keys, dates may be scrolled by
day, week, half month, month, same day of the month, first day of the month, last day of
the month, first day of the year, last day of the year, quarter, same day of the quarter,
year, same day of the year, first day of the first week of the year, and first day of the
last day of the year. You may vary the list with each entry "object" to reflect
the purpose of the particular entry.
 |
Date Functions. In addition to the scrolling
date functions, ProDomus Date Tools will calculate the week of the year according to local
calculation rules, day of the week, days left in the year, business days, holidays, and
days between dates based on a 30 day month |
|
Date Rules. Rules for date calculations vary
from country to country -- the US standard of Sunday being the first day of the week and
the first week of the year being the one in which January 1 appears does not apply in most
other countries. PDDT functions for calculating the Week Of The Year or the Day Of The
Week recognize these rules. |
|
True or False Date Functions. Is it a holiday?
Code is provided for calculating US holidays. This function or any function similarly
prototyped may be passed to business day functions to determine whether a date is a
business day and the number of elapsed business days between dates. PD Date tools also
provide functions for determining whether it is a leap year, valid date, or week day. |
|
Recurring Date. A special True or False
function determines whether a date B is a recurring instance of date A: weekly, every two
weeks, every half month, monthly, the same day of the month, every two months, and more. |
 |
Calendar. If you are satisfied with a calendar
that just pops up and returns a date, or even uses drag and drop, you can use the PD Popup
Calendar among many. However, if you want user controllable options between a system or
other fonts, modal or MDI operation, multi-threading, localized month and day names,
colored weekends, holidays, and other scheduled items, this calendar is the one to use.
- Reads Windows Registry from Month and Abbreviated Day names, First Day of Week,
Week of Year Calculation Rules.
- Optionally MDI/Non MDI window
- Threaded/Non Threaded Options
- Colored weekend, holiday, and scheduled dates.
- Range Limits
- Hot Keys -- Uses Scrolling Date Class.
- Transparent and Wallpaper options.

Time Zone Information. 32-bit applications may
retrieve local names for Standard and Daylight Savings time, the UTC (Universal Time)
bias, the date and time of transitions, and the user's current set up. Getting this
information required breaking the UNICODE barrier. |
 |
Personal Calendars. Sample code illustrates one
way to create multi-threaded personal calendars with appointment schedules, appointment
details, "to do" lists, and recurring dates. The possibilities are virtually
limitless. |
 |
International Information. In additional to retrieving
international date rules from the registry, ProDomus Date Tools gets full and abbreviated
month and day names. It stores this information in a global group that is always available
to your application. If your application does not have access to the windows registry, you
can use the 32-bit Date File Creation Utility to create an Ini type file of
registry information. |
Source Code. Breaking our usual rules, ProDomus Date Tools include source
code for the example planner procedure and the International Calendar, schedule, and
holiday calculation functions.
Templates
The PD Date Tools is implemented with simple to use templates.
A Global Extension Template with three entries adds the library and calendar source
code to your application. These may be compile internally or externally.
An Initialization Extension Template initializes the popup calendar, adding default
features and schedule to the calendar. A code template sets the default date function
rules; this would typically use default entries without your having make changes.
A Date Scrolling Extension template then sets the behavior of date entries -- each may
use the default settings or have its own; the extension requires you to identify the entry
control and a default date.
The Calendar Extension Template may be used to call the calendar for the completion
event of any control with a completion event. Minimum entries identify the calling
control, a default date, and a date field.
A Calendar Button Control Template allows you to place a button next to a date entry
field. The minimum entry identifies the entry control. This can call a threaded calendar
that will mimic the behavior of the calling window: it will iconize, restore, and close at
the same time as the calling window. Pressing the button will give the calendar focus if
it has already been opened.
The Time Zone Code Template retrieves the user's time zone information. The template
allows to perform different actions depending on function call results: unknown time zone,
standard time, daylight time, and function failure.
Example Applications. Two sample applications are included. One
illustrates a simple use of the scrolling function and popup calendar. The second includes
appointment calendars and "to do" lists for multiple calendar users. Quote

Thanks for the great template. Use it all of the time with my programs in
Clarionz. |
