CXTPDatePickerControl wndDatePicker; wndDatePicker.SetShowWeekNumbers( TRUE ); How to bring numbers of weeks to such a format? http://en.wikipedia.org/wiki/ISO_8601 -
------------- Xtreme ToolkitPro v13.1.0, static, VC++6 |
ISO 8601 includes the http://en.wikipedia.org/wiki/ISO_week_date - ISO week date
system, a numbering system for weeks – each week begins on a Monday and
is associated with the year that contains that week's Thursday (so that
if a year starts in a long weekend Friday–Sunday, week number one of
the year will start after that). For example, week 1 of 2004 (2004W01)
ran from Monday 29 December 2003 to Sunday, 4 January 2004, because its
Thursday was 1 January 2004, whereas week 1 of 2005 (2005W01) ran from
Monday 3 January 2005 to Sunday 9 January 2005, because its Thursday
was 6 January 2005 and so the first Thursday of 2005. The highest week
number in a year is either 52 or 53 (it was 53 for year 2004). http://en.wikipedia.org/wiki/ISO_8601 -Replies:

Hi Codejock, It looks like the current version doesn't support ISO week numbers. This is the format that is used in most European countries. Our customers has now stared noticing the datepicker showing "wrong" week numbers, and we need to provide a solution before January 1st. Will Codejock be supporting ISO week numbering this year, or will the only solution be to replace your control? |

It supports it. The FirstWeekOfYearDays property contains the current required number of year days that occur in the first week of the year. The FirstWeekOfYearDays property is needed because the first week of the year can be different depending on how many days occur in the first week. For example, in Germany the first week of the year has to be a week with at least four days. In the United States the first calendar week starts with January 1st. wndDatePicker.FirstWeekOfYearDays = 1 wndDatePicker.FirstWeekOfYearDays = 4 wndDatePicker.FirstWeekOfYearDays = 7 wndDatePicker.FirstDayOfWeek = 4 ' Wednesday |

| It depends on your country. If you are the same as Germany, then yes, you only need wndDatePicker.FirstWeekOfYearDays = 4 |

I can get LOCALE_IFIRSTWEEKOFYEAR
from GetLocaleInfo http://msdn.microsoft.com/en-us/library/dd373772%28VS.85%29.aspx
Please write corresponding FirstWeekOfYearDays values: if LOCALE_IFIRSTWEEKOFYEAR = 0 then FirstWeekOfYearDays=? if LOCALE_IFIRSTWEEKOFYEAR = 1 then FirstWeekOfYearDays=? if LOCALE_IFIRSTWEEKOFYEAR = 2 then FirstWeekOfYearDays=? ------------- Xtreme ToolkitPro v13.1.0, static, VC++6 |
