Re: [Mono-dev] Doc for odbc

I guess I didn't understand the unfinished concept or your answer... In other words... even if there are unfinished members on a class, and consecuently the class is marked as unfinished, is still the class usable? (I thought I couldn't...) Originally there is no one who mentioned unfinished concept so I just ignored it (and [1] as well). What are they? What are you talking about? What are you asking about? Sorry, I forgot to paste the link (Ooops 0_o), actually [1] meant to be: [1]http://www.go-mono.com/docs/index.aspx?link=T%3aSystem.Global ization.DateTimeFormatInfo I hope it would answer that questions... May be I lost something... what do you suggest to use instead of DateTime.Parse() or DateTime.ParseExact()? I don't understand why we need to find something instead of DateTime.ParseExact(). Just use it. So, should I use a string specify for myself (such as dd/MM/ H:mm*:ss*) for the format? Yes, or alternatively use CultureInfo.DateTimeFormat.GetAllDateTimePatterns() or whatever. Ok, got it. The fact that there is no decent alternative of DateTime.Parse() (that would consider only explicitly-defined date time format strings) is a problem in Microsoft.NET, not ours. (oh, yes we could provide alternative decent library if there is need though ;-) I see ^_^ Alfredo. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
