During any software life cycle, you will want to phase out some code, and most likely want to mark code to be phased out in the future.
So here are two examples on how to do that in C# and in Delphi that just shows the effects of obsoleting/deprecating code.

I missed EKON 16 as both they and we moved outside the regular conference season.
So I missed this session: EKON 16: MSBuild // Speaker Deck that has these GitHub source examples: gingters/EKON16_MSBuild.
Thanks Sebastian Gingter for pointing me at this!
msbuild is used by both Visual Studio and Delphi for building projects, and this session gave me some good ideas to improve the Continuous Integration projects I already had into place.

Interesting, I never knew that [WayBack] Process Monitor has had an API to send messages to, but it has had this ability for almost 5 years: [Archive.is] See the I/O You Caused by Getting Your Diagnostic Tracing into Process Monitor | Wintellect.
I did know about [WayBack] OutputDebugString and the DBWIN protocols, but this was new.
The ZIP file for Process Monitor is offline (but you can find it by searching for ProcMonDebugOutput.zip), and contains .h files and a .NET example.
Thanks [WayBack] Oliver Giesen for the [WayBack] Delphi translation!

Thanks Stefan Glienke for pointing me to NCrunch for Visual Studio:
NCrunch is an automated concurrent testing tool for Visual Studio.
It intelligently runs automated tests so that you don’t have to, and gives you a huge amount of useful information about your tested code, such as code coverage and performance metrics, inline in your IDE while you type.

A few libraries for writing and/or reading CSV files in .NET:
Most of the above links come from these SO questions:
Together with the links from my previous CSV post If you think CSV is easy; think again that should get everyone going.

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:
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 »

Two ways to do a case insensitive string replace without using RegEx (which often is not a solution).
Thanks User Tim Schmelter for pointing me at those.

Normally you would not want to use a reserved word as an identifier. But sometimes it can be very convenient, for instance for a code generator that wraps remoting calls or does ORM.
Both Delphi and C# have an escape for this:
The prefixes are to tell the compiler knows you really know what you are doing, and are using a reserved word as an identifier.
The cool thing: in the Run Time Type Information (Delphi) or Reflection (C# and VB.NET) you will see the names without the prefix.

Yesterday I posted this question on StackOverflow and G+: Is there a url or site like example.org which always produces a 404 error?
Soon after that, I found out three links that produce predictable HTTP status codes:
They also work for https:
- 200: https://www.google.com
- 204: https://www.google.com/generate_204
- 404: https://www.google.com/404
Edit 20241223: these also return a 404: http://www.google.com/undefined and https://www.google.com/undefined
On StackOverflow very few people even noticed the question, probably wondering “why?”.
I’m using these links for positive and negative testing of some http / https handling code that needs to be good at coping with positive and negative responses.
In my testing life, I’ve learned the hard way that both negative and positive tests are core part of your suite, hence the question.

Bosak posted an interesting piece of code on StackOverflow last year. His particular code was in C#, but it does not matter what kind of compiler you use:
Sometimes a compiler will complain about unreachable code, for instance when it thinks a function never returns a value.
But you know the program logic does.
Simple solution: When you have code that never should be reached: throw an appropriate exception.
public static int GetInt(int number)
{
int[] ints = new int[]{ 3, 7, 9, int.MaxValue };
foreach (int i in ints)
if (number <= i)
return i;
return int.MaxValue; //this should be unreachable code since the last int is int.MaxValue and number <= int.MaxValue is allways true so the above code will allways return
}
The last return could be replaced like this, as proposed by Matt Houser: Read the rest of this entry »
