Interesting: about a year and a half ago, the Nikon SDK C# wrapper project started ad sourceforge.
Basically, it allows you to integrate the operation of your Nikon DSLR into your .NET projects.
It has some very interesting features:
- Control your Nikon DSLR via USB
- Capture Jpeg and Raw images directly to system memory
- Receive ‘Live View’ images
- Record Video
- Query and change camera settings (Exposure, Aperture, ISO, etc.)
- And much more…

Wow, it seems I’ve been living under a stond since early 2011: the first StudioShell checkin.
[WayBack] StudioShell opens marvellous possibilities in Visual Studio 2010, 2012 and up.
Just look at the feature list: Read the rest of this entry »

It is almost 3 years that Ostemar wrote an interesting answer on Stack Overflow to the question
Why does .NET use banker’s rounding as default? – Stack Overflow.
Few people (even many programmers don’t!) know about rounding and how it can influence software, let alone what bankers rounding does so lets set a few things straight first.
Rounding matters. Depending on the kinds of software you write, it matters a little, or a lot.
For instance, in these categories, it can matter an awful lot:
- Financial applications
- Statistical applications
Bankers rounding means rounding half even. Which means that #.5 will round to the even number closest to #.
In bankers rounding, 1.5 rounds to 2, 3.5 to 4 as does 4.5, -1.5 rounds to -2, -3.5 to -4 as does -4.5.
This is called “unbiased” because for reasonable distributions of y values, the expected (average) value of the rounded numbers is the same as that of the original numbers.
This is contrary to what the majority of people are accustomed to: Round half away from zero is taught in most countries (even for the Dutch, despite the alias “Dutch Rounding” for round half to even).
Round half away from zero rounds 1.5 rounds to 2, 3.5 to 4 and 4.5 to 5. Negative numbers round like this: -1.5 rounds to -2, -3.5 to -4 as does -4.5 to -5.
This is only free of overall bias if the original numbers are positive or negative with equal probability.
In short, .NET uses bankers rounding because it follows the IEEE 754 rounding rules.

I totally agree with Tim Anderson here:
Open source, native code compilation, and an innovative compiler: it adds up to huge changes for C# and .NET, positive ones as far as I can tell.

The first bulleted link below has been living in my drafts like forever (i.e. somewhere since mid June 2009), so time to write a bit about ISO 8601 and .NET.
First a few links about converting a DateTime into ISO 8601 string format:
Some solutions use the “K” as a time zone specifier. At first, I couldn’t find any documentation for it, not even Google Search for Google Search for “ssK” DateTime ToString returns anything useful.
Later on, I found The “K” Custom Format Specifier in Custom Date and Time Format Strings.
So my preferred solutions for me are these:
System.DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssK");System.DateTime.Now.ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssK");
I avoid these:
System.DateTime.Now.ToString("o");
because it gets you too many digits in the second fracion.System.DateTime.Now.ToUniversalTime().ToString("s") + "Z";
because it is less clear what it does (might be resolved with a comment).

Thanks User Andrew Hare – Stack Overflow for answering this on Stack Overflow.
I’m pretty sure it works in all .NET and C# versions starting with 2.0.
Here is a hack-ish way to do it without having to load the entire output string into an XmlDocument: Read the rest of this entry »

A while ago, I was working with a not so cooperative corporate firewall. All web browsers would work fine, but most other applications would not go through the proxy in a nice way.
For instance, DropBox would show the dreadfull “Connection Error” dialog shown on the right.
That dialog basically means “Dropbox has no clue what happens, try fiddling with your proxy or account settings, then press Reconnect Now” to retry.
Many other applications had issues (for instance Visual Studio connecting to Team Foundation System was very unreliable and the workarounds clumsy).
CNTLM: not the solution
I got inspired by the [WayBack] I code and code: Tutorial: How to use Dropbox behind a corporate proxy server using CNTLM, even though I was pretty sure the corporate firewall was not NTLM based.
And indeed, CNTLM -v -M http://google.com -c CNTLM.INI would give errors like this:
cntlm: Proxy returning invalid challenge!
headers_send: fd 4 warning -999 (connection closed)
Connection closed
HTTP Fiddler: looks promising
So I fired up my old buddy [WayBack] Fiddler 2 HTTP debugging proxy.
Further on, you will learn that Fiddler2 is much more, but right now it is enough to know that it basically sits as a local proxy between your applications and the outside world. Read the rest of this entry »
