EncodeFlags

Looking at "QA" they also seem to have dropped support for dates.
It's worse than that: based on QA, they've also dropped support for parameterized queries! :rolleyes:

It makes no sense: 1 - There are combinations not covered by the encoder. ie
Alarm | Malfunction2 - It only makes sense to encode it if whatever is using does not support integers (or maybe it's meant to have a meaningful representation on a digital display, still what if it's alarming and malfunctioning). 3 - Should have used enum's HasFlag method. Now, an expert in C# and 25+ years in programming could only do this if he's hung over, lazy, dumb or having an idea so bright nobody can understand.To alcohol!

It's a flagged enum, so how would he represent the state

Well spotted.

I agree with you. I know the guy who wrote that code, and the circumstances: it's fresh code written this week. Some time ago, I discussed with him his obsession of encoding everything in magical ints or one-letter-strings, sometimes also providing "endode"/"decode" functions for converting between the magical ints and the one-letter-strings and the other way round...

It is even worst than that, based on the QA they have also dropped support for brains
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

He has a bug in in code by not returning a useful defalut value. And its also missing in the enum. If he is an expert in Solitaire I may know him? :~

useful defalut
What's that?

An expert of programming and C# with some 25+ years of experience in software engineering wrote a really useful function:
private string EncodeFlags(EventType _eventType)
{
if (_eventType == EventType.Alarm)
{
return "A";
}
if (_eventType == EventType.PreAlarm)
{
return "P";
}
if (_eventType == EventType.Malfunction)
{
return "M";
}
return "";
}Already this function alone is some kind of WTF. But let's look at the definition of the input parameter which he translates:
[Flags]
public enum EventType
{
None = 0,
PreAlarm = 1,
Alarm = 2,
Malfunction = 4
}So he translates an
enumwith aFlagsattribute to astring, ignoring the fact that they are flags, in order to store that value in a database eventually. :~ X|Bernhard Hiller wrote:

It could have been changed to [Flags] after-the-fact and this code was just not updated.

Ignore my previous post. I used to work with someone like that. He no longer works here. Smart guy, very capable, but continuously made "mistakes" like that. His "code" has caused us lots of grief.
