It comes down to these cases for XML elements having maxOccurs="1" (which the default for maxOccurs):
- adding
nillable="true" will convert from a regular type to a nullable type.
- adding
minOccurs="0" will add boolean …Specified properties in the generated C# for each element.
- you can have both
nillable="true" and minOccurs="0" in an element which gets you a nullable type and a …Specified property.
Note I’m not considering fixed or default here, nor attributes (that have use instead of minOccurs/maxOccurs, but do not allow for nillable) nor larger values of maxOccurs (which both xsd.exe and xsd2code regard as unbounded).
From the above, XML has a richer type system than C#, so in XML there are subtle a differences between:
- an explicit
nil in the XML element
- the XML element being absent
- the XML element being empty.
Hopefully later more text and examples to show how to actually work with this.
Delphi related to minOccurs:
Note that xsd2code.codeplex.com (unlike XmlGen#) has at least two forks at github:

A while ago, StackOverflow user Kobus Smit did some brilliant editorial work that – due to current state of StackOverflow – sort of fired backwards: his question got marked as duplicate before he could post his excellent answer. After that answer was posted, the oh-so pride SO-demi gods never took any energy to revisit to see which answers were best.
His simple question:
How can my Delphi app easily write to the Windows Event Log?What is the difference between TEventLogger and ReportEvent? How do I use the ReportEvent function?
Which somehow should be encompassed by this Delphi 5 question (apparently that 15+ year old Delphi version is still considered current by the SO demi-gods).
The answer summarises and extends existing answers spread out over StackOverflow and adds an EventLog git repository wrapping the ReportEvent and RegisterEventSource (which somehow is always a pain: Delphi services for instance often forget that).
Lesson learned when doing editorial work:
- prepare both the answer and question in markdown off-line
- ensure you mention in the question that the answer is meant as collection of “best of” answers found elsewhere
- post the question and answer in rapid succession
- cross your fingers for the StackOverflow demi-gods being in a good mood

Every methodology has their own. I like the ones in the picture, of which the teacher obviously didn’t get them at all. Maybe because COP 3331 is about Object Oriented Design?
- Denial
- Bargaining
- Anger
- Depression
- Acceptance
Sounds familiar?

PowerShell 4.0 is madly in love with “English (United States)”
A long time ago I started writing up my blog post like this in March 2015 when I bumped into this the first time when upgrading from PowerShell 2 to PowerShell 4:
It seems there is no real workaround:
Good and not so good news: after reading the below linked posts, this is what works:
- PowerShell 4 and up works fine with any [Wayback] Lucida Console size (including 12) and boldness
- only when the “Language for non-Unicode programs” is set to “English (United States)”.
- PowerShell 4 works fine with [Wayback] Consolas on any size and boldness
- for any “Language for non-Unicode programs”
So if you’re like me and switch between “Dutch (Netherlands)” and “English (Ireland)” a lot (both use the EURO as currency, but have distinct enough other locale settings to cover a lot of European stuff) then you need to get used to the Consolas font.

Edit 20210930: a possible solution
I need to fire up some old systems having PowerShell v3 or v4 on them to test the below possible solution.

Interesting:
just for completeness:
testssl.sh is a nice, console-based tool to check ssl-setups of any ssl/ts – enabled servers, in oposite to ssllabs
It helped me solving this:
Host: http://www.beginend.net
Reason: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
Within the testssl.sh directory, you can use this to test with many cyphers:
OPENSSL=./openssl-bins/openssl-1.0.2-chacha.pm/openssl32-1.0.2pm-krb5.chacha+poly ./testssl.sh www.example.com

One of the things I figured out with Windows 7 and up is that when logging in over RDP an existing user would be disconnected unlike Windows XP that would logoff the existing user.
If you want them to logoff there are basically two options:
I will dig into the scripts one day as I’ve not needed this too often (I use Task Manager for now).

On the research list: TIdSchedulerOfThreadPool (now that TIdThreadMgrPool is gone).
Need to manage the lifetime of these as I don’t want the threads to live forever, but also don’t want to make the instantiation cost too high.
Most likely I want to wait for them to finish as well upon process exit, so this might be worth a look as well:

Most developers I speak to have trapped into a case of copy/pasting some source code containing quotation marks from documentation or post immediately failing on curly quotes like left double quotation marks (“) and right double quotation marks (”) that should have been regular double quotation marks (").
I’ve tried to search for a way to automate the replacement process to “ASCII quotation marks”, but not found an on-line engine yet. The best I could find was this post: java – Replacing unicode punctuation with ASCII approximations – Stack Overflow.
Note it’s not only the auto-correct of office applications. For instance “blog engines” like WordPress do that too, unless you add a code or pre around them:
- code:
"blog engines"
- pre:
"blog engines"
Very irritating, but apparently nowadays beauty trumps accuracy.
