If you want to place a window at a specific place in WPF, it will work pretty much as you expect—unless your DPI is 120 (the default is 96). Here’s a sample that shows how to put it where you want.
In this case, I want to put a window just under another control, aligned [...]

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:
Allows user [...]

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. I also updated the sample demo to use multiple threads to read the CPU usage to demonstrate the thread safety clearly.

Updated 2/4/2009: I changed the implementation of these classes from the original:
Instead of a critical section, InterlockedIncrement/Decrement is used.
The sample driver program now demos using multiple threads using the CpuUsage class to show thread safety.

Just to make it clear, there is no API called GetProcessCpuPercentage(). To [...]

For my current project, I needed a panel to layout controls vertically. The TableLayoutPanel can be awkward to work [...]

I’ve been working on a project using Visual Studio Tools for Office 2008 (VSTO) and at one point I needed to get the colors for categories in Outlook 2007. There are actually 3 colors, and they are returned as uint’s–why the .Net wrappers don’t convert to colors for you, I don’t know (to avoid linking [...]

Tracking changes in database tables is an incredibly useful feature–especially for operational data that can change often. Having recently had to implement this feature, I thought I’d share some of the techniques I learned.
Sample Database
First, let’s conceptualize a very simple database consisting of user information (name, date of birth), and e-mails. A user can have [...]

This kind of thing has happened to be a few times now, so I thought I’d share the fun.
In one of our pieces of software we have a process that looks like this:
void MyThread()
{
while (true)
{
DoFunctionA();

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 [...]

This is an issue I run into constantly at my job.
Frank Kelly wrote up a good summary of some items. They’re simple, easy to understand, easy to follow, even for non-programmers.
In fact, I’m sending this link out to everyone in my group here at work.
