[aus-dotnet] UML 2 and Microsoft

[ILT]

Perhaps also a little bit off-topic, but I haven’t been across any argy-bargy about why (if it’s true at all) Microsoft is “against” UML and in particular UML 2.0  - this ComputerWorld / InfoWorld interview points the finger (at least, the IBM guy does) –

 

InfoWorld Editor at Large Paul Krill talked about the subject with Brian Selic, IBM Distinguished Engineer and co-chairman of the OMG task force on UML 2.0.

Can anyone educate me on this?

I was able to save the page to disk fine, but if you're having problems with that particular page, click on the Printer Friendly button on the left and save that version - less than half the size (and most of that would be unneeded _javascript_).

Curiosity about 1752 and the change to the Gregorian calendar led me to link to the page

http://www.ancestry.com/learn/library/article.aspx?article=3358

and I decided to save it to disk – but IE6 won’t play

 

I’ve asked this on MS newsgroups (I hope not here; if so, sorry folks) and don’t get a wholly convincing answer. The work-around I use when I really want” a page is to print as a PDF file. But that’s not always great, because some webpages are made for screens at 1400px width and can’t print to paper (hence, a PDF default A4 pagesize slices off the right margin).

 

Any thoughts?

   Your info is correct for England.  In Russia, IIRC, the days were removed in 1917.

By the way, do people know why SQL Server uses 1753?

 

About 8 years ago I was doing some SCO System admin, when I stumbled across some interesting information reading through the "MAN" command (online manual) pages, looking for information about date-related commands. It's interesting to note that in September 1752, 11 days were subtracted from that month in Gregorian calendar (the one used by western society today). Interestingly SCO Unix displayed a calendar for that month - with exactly 11 days missing.

 

Curious about the details of the calendar change, do a search for words "gregorian","1752" and "semptember". eg...

http://www.ancestry.com/learn/library/article.aspx?article=3358

 

.Net uses the same method as SQL for controls DateTimePicker and MonthCalendar - you cant display it because of a curious mindate. Not much of a problem for most applications.

A date always has a value.

Date dt = new Date() = 00:00:00.0000000, January 1, 0001

Your problem is that this is probably less than the allowed value for your datatype.

eg SQL Server datetime type has a min value of  January 1, 1753 .

 

Usually it's best to insert a null for unassigned dates.

ie. if ( dt > DateTime.MinValue)

        set param here...

I have property defined as datetime...when i read the property wihout any assignment the value is #12:00:00 AM#

 

if i use isdate..it returns TRUE but this will not submit to SQL...How do i detect a valid datetime for SQL?
