.NET Forum / .NET Framework / New Users / August 2005How to get DateTime.ToString() to use user preferences?
I am trying to format a DateTime using ToString(). I am using the "t" formating for short time. The system is configured to use HH.mm.ss but the result formatted time is in the default short time of h.mm tt. I have tried passing in a DateTimeFormatInfo that was returned from DateTimeFormatInfo.CurrentInfo, but that did not work. Bottom line is that I don't have any idea how to do this. I expect that it is simple once I know the plan. Anyone have code to get this right they could share? Thanks ------------------------------------------- Roy Chastain KMSYS Worldwide, Inc. http://www.kmsys.com Try something like: Now.ToString("HH.mm.ss") > I am trying to format a DateTime using ToString().

I asked how to get it to format according to the USER's preferences. I know how to do it by hard coding the format. >Try something like: > Now.ToString("HH.mm.ss") [quoted text clipped - 12 lines] >> KMSYS Worldwide, Inc. >> http://www.kmsys.com ------------------------------------------- Roy Chastain KMSYS Worldwide, Inc. http://www.kmsys.com This should do if for you: DateTime.Now.ToString(Thread.CurrentThread.CurrentCulture) The resultant string format is influenced by the settings in the Regional Options control panel.

That gets me closer. Thank you. However, I am still having a problem. I tried DateTime.Now.ToString("t",Thread.CurrentThread.CurrentCulture) because I just wanted the time portion and I expected that it would display the time in the format specified in the Regional Options, but instead it continues to display h.mm tt. t format says, it is associated with the ShortTimePattern of the DateTimeFormatInfo Is this a bug, bad documentation, wishful thinking on my part, or fill in the blank? Thanks >This should do if for you: > [quoted text clipped - 17 lines] >> KMSYS Worldwide, Inc. >> http://www.kmsys.com ------------------------------------------- Roy Chastain KMSYS Worldwide, Inc. http://www.kmsys.com Hi Based on my test, the culture will work as expected. Here is my test sample. MsgBox(Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortTimePattern) 'current format H:mm:ss MsgBox(DateTime.Now.ToString("t", Thread.CurrentThread.CurrentCulture)) 'Here the time will be H:mm:ss format Dim o As CultureInfo = Thread.CurrentThread.CurrentCulture.Clone() o.DateTimeFormat.ShortTimePattern = "h:mm:ss" Thread.CurrentThread.CurrentCulture = o MsgBox(Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortTimePattern) MsgBox(DateTime.Now.ToString("t", Thread.CurrentThread.CurrentCulture)) 'Here the time will be h:mm:ss format. So I think you may try to check the Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortTimePattern.

I have looked at the ShortTimePattern in the returned culture and yes the output matches it. The question is, how do I get ToString to format a date/time the way the customer wants it formatted? (Note in this case, the way the customer wants it formatted is the way he defined in the regional settings.) Is this something as simple as a problem with the words Short and Long when applied to time patterns. I noticed that there are also long time patterns and they seem to have hh instead of h. Could it be that the regional settings are really showing up in the long time pattern instead of the short one. (Long and short dates make sense to me - Long and short times do not - At least not in US-english) Thanks >Hi > [quoted text clipped - 24 lines] >Get Secure! - www.microsoft.com/security >This posting is provided "AS IS" with no warranties, and confers no rights. ------------------------------------------- Roy Chastain KMSYS Worldwide, Inc. http://www.kmsys.com Hi If you have a look at the regional setting, you will find that there is short date, long date and a time. But there is no a short/long time setting. So it seems that the .net framework will map the short date, long date. Map the long time to the time in the regional setting. It did not map the short time, because there is no such one. Try to run the code below. 'Four date/time formatting MsgBox(DateTime.Now.ToShortTimeString()) MsgBox(DateTime.Now.ToLongTimeString()) MsgBox(DateTime.Now.ToShortDateString()) MsgBox(DateTime.Now.ToLongDateString()) If you run the code below, you will find if you change the time in the regional setting, the long time will change. But the shorttime and short time pattern will not change. But the ToShortTimeString and DateTime.Now.ToString("t") accord with ShortTimePattern. MsgBox(Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortTimePattern.T oString()) MsgBox(DateTime.Now.ToString("t")) MsgBox(Thread.CurrentThread.CurrentCulture.DateTimeFormat.LongTimePattern.To String()) So for your scenario, I think you may try to use the long time instead, if necessary you can exact the short time from the long time string.
