Someone needs to sit down with the guy and give him some 'help' to understand decent coding practices. Keep a hammer ready ...

Code Reviews

Code Reviews
Here is a great rule. When someone gets multiple "mandatory" changes needing to be made as a result of a Code Review. Then you must review weekly, ALL of their code. This continues until they no longer require "mandatory" changes for a few weeks in a row.
The goals are:
1) Slow them down
2) Get them to proactively ask people how they should code/name something
3) Show them the right way (for your group) to do things
Our Code Reviews have 3 Comment Levels:
- Mandatory: We will not let this stand in production, must be rewritten
- Suggested: We are not thrilled, but if you can "really" defend it.
- Noted: We are just making a note, take it or leave it (Variable names, Variable comments)
Make Code Reviews fun. Friday starting at lunch time with pizza brought in. It helps you to detach from the depth of coding for the weekend. Besides, Code Reviews are how Good Developers help new Developers!

I have code like that, but sometimes it is not so simple. Not all objects have an "enabled" property, and sometimes I may need to enable some and disable others. Keeping the switch, or at least an "if ... else" structure, makes for more clarity, just in case these oddball things are necessary.

FirstControl.Enabled = SecondControl.Enabled = enabled;

At least, his casing is ok.
while (true) {
continue;
}

Thanks for posting! After two weeks without a new thread, I was starting to think that we are all working on perfect code! BTW, the example is perfect for getting your LOC up!

You aren't working with my previous employer, are you?

The advantage of a switch is that it bails as soon as a test passes, thus reducing conditional branching.
Here you could use an if else.
|
|
|
|
|
Or take it out altogether as it's setting 2 Booleans.
|
|
|
|
|
In that case it has the same advantage as the "if" would have; but if that is an important 'optimization', then you already have a bigger problem

In my experience Microsoft is pretty much immune to optimisation. You can reduce branching by one or two orders of magnitude and the crappy performance just doesn't budge.
|
|
|
|
|
Probably because it is a micro-optimization; you won't notice much difference if it merely saves you the toggeling of a boolean.

Ha! It was actually an image processing filter mask which used pointer arithmetic. I invented something I called a Summation Threshold Filter which should have been ten times quicker than a Median filter.
Let's just say that this was not apparent.

Umm...that's not true. A switch will continue to fall through until you get to a break statement or the end of the switch (i.e. the default case.) On the other hand, if/else statements do bail as soon as the first passing conditional is found and the associated code block is executed.

Not in C# - every case is required to have a terminating statement (break , goto , return or throw ).
Unlike C++, C# does not allow execution to continue from one switch section to the next.
...
C# requires the end of switch sections, including the final one, to be unreachable. That is, unlike some other languages, your code may not fall through into the next switch section.

You're right about the switch case and fall through. Been spending too much time playing with C++ lately. My apologies.

I believe a switch is just a calculated jump statement. It doesn't work it's way through all the previous possibilities. Yes. Once calculated, the program goes to the break statement then jumps out appropriately. Switch statements are quite fast. In this case, I don't see advantage either way as an if statement is very simple too.
|

Well I kind of assumed you knew how to write a switch.
|
|
|
|
|
The only reason I could think for writing or keeping the code this way would be if enabled became an enumerated type and had more than 2 states.
|
|
|
|
|
In that case - create it as an enumerated type, with two values. You may then expand the enumeration without rewriting the existing code.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

FirstControl.Enabled = !FirstControl.Enabled;
SecondControl.Enabled = !SecondControl.Enabled;
|
|

Couldn't resist:
void EnableFromValue(bool enabled)
{
FirstControl.Enabled = enabled;
SecondControl.Enabled = enabled;
...
}
|
|
|
|
|
it is simple :
void EnableFromValue(bool ?enabled)
{
FirstControl.Enabled=enabled.HasValue?enabled.Value:false;
SecondControl.Enabled=enabled.HasValue?enabled.Value:false;
}
|
|
|
|
|
This works for me
FirstControl.Enabled = SecondControl.Enabled = (enabled) ? false : true;
|
|
|

LOL! I recently went through my company's entire code base to purge out constructs such as "? true : false".
Even more fun were comparisons such as "if (some_int_var == TRUE)". That's great unless, say "TRUE" is defined as 1 and your variable is set to -1.
