RosettaCode: cool way to improve your coding skills

Posted by jpluimers on 2015/01/22

Wow: I feel like having lived under a stone for 8 years, as RosettaCode has been alive since it was founded in 2007 by Mike Mol.

The idea is that you solve a task and learn from that, or learn by seeing how others have solved tasks or draft tasks.

So in a sense it is similar to the Rosetta stone: it has different languages phrasing the same tasks.

There are already a whole bunch of languages on RosettaCode (of which a few are in the categories below), and you can even suggest or add your own languages.

When you want to solve tasks, be sure to look at the list unimplemented tasks by language that leads to automatic reports by language (for instance two of the languages I use most often: C# and Delphi).

I’m sure there are lots of programming chrestomathy sites, even beyond the ones, and it feels very similar to programming kata sites.

Favorite Documents extension for Visual Studio 2010 and up

Posted by jpluimers on 2015/01/20

This used to be a great Delphi-only feature that I missed in Visual Studio, but I found the downloadable free extension Favorite Documents extension.

It is a by Sergey Vlasov, who has a whole bunch of free and paid Visual Studio add-ins, extensions and tools.

.NET/C#: Chaning the ForeColor of a ReadOnly/Disabled TextBox (via: Stack Overflow)

Posted by jpluimers on 2014/12/24

Once every while you still do WinForms work, and bump into something you hadn’t bumped into before.

This time it was trying to set ForeColor = Color.Red on a ReadOnly TextBox for displaying error messages:

  • Using a TextBox means the user can still copy the text to the clipboard.
  • Using a Red foreground draws enough attention (it’s was an app with a really busy user interface).

When setting a TextBox from ReadOnly = false to true sets the BackColor from SystemColors.Window (usually white) to SystemColors.Control (usually light grey), and leaves the ForeColor to SystemColors.WindowText (usually black).

Setting ForeColor = Color.Red (funny there is a plural in SystemColors but not in Color) it doesn’t display it as such:

To my surprise, the TextBox had ReadOnly text (you could copy, but not modify it), which showed with a a grey (SystemColors.Control) BackColor and a black (SystemColors.WindowText) ForeColor: the defaults for a ReadOnly TextBox, not using my ForeColor = Color.Red;

I vaguely remembered there was some odd way of solving this, but since I hadn’t written a blog article about it back then (somewhere around .NET 1.x or 2.0 I didn’t have a blog yet), I was glad that Cheetah posted this answer on StackOverflow: Read the rest of this entry »

Excessive CPU usage in WheaAttemptPhysicalPageOffline when using Intel HD graphics – via Intel Communities

Posted by jpluimers on 2014/12/12

I had some excessive CPU usage (30% on a 4-core system) inside WheaAttemptPhysicalPageOffline when using an Intel HD graphics 2500 GPU.

At first I thought I needed to convince IT to update the drivers: Intel HD graphics causing high CPU utilization | Intel Communities.

Then I closed all Visual Studio 2013 instances and the CPU usage went to normal.

So I’m suspecting a WPF issue somewhere.
