When WPF first shipped, there was a noticeable lack of certain controls we’ve become used to in Win32 and WinForms: Calendar, DateTimePicker, and NumericUpDown. WPF 4 adds Calendar and DatePicker, but not anything for numeric entry.
For my solution I wanted something that behaved very similarly to the WinForms NumericUpdown control.
Some of the specifications:

I made a important changes to the CPU usage code and have updated the article to reflect it. Instead of a critical section, the code uses just the interlocked increment/decrement functions.

This kind of thing has happened to be a few times now, so I thought I’d share the fun.

Working on an MFC app that has just been converted to Unicode (finally!), I noticed that one button (which is created dynamically) is too small to fit the text in Korean (and Russian and a few other languages).
The code was calling something like:

CSize sz = m_btAdjustColors.GetDC()->GetTextExtent(sCaption);

It seems correct, but these script languages are throwing it [...]
