The idea here is that, as with any other form of math that we know of, we cannot divide by zero in a SQL call. Therefore, running this code : SELECT ( 3765 / 0 ) AS value ; if  you ever tried this , result of SQL server would be  : To prevent this sort of error from being thrown, author Hugo Kornelis suggests using a NULLIF () in the divisor of the equation. NULLIF () takes two arguments and returns NULL if the two values are the same and can be used to turn the divisor from a zero into a NULL which, in turn, will force the entire equation to become NULL .  SELECT ( 3765/ NULLIF( 0, 0 ) ) AS value ; Therefore, while we try running modified query (as above) , we would end up getting Null Object , which reduces the risk of handling divide by zero : NULLIF(0,0) returns NULL since zero is equal to zero , which makes SQL statement to return NULL . Till this point its pointless example since both zero values are hard coded . But imagine if...

The two-way data binding in AngularJS is very powerful, especially when there is a direct mapping of input data to view-model-data. But, when the data mapping requires some translation, interpretation, or validation, you need to get your hands a little dirty - you need to get more involved in how data changes are propagated within your Controller(s). As this has happened to me, I've been forced to think more deeply about my AngularJS application architecture; and, as a result, I've found that my life is often simplified (in the long term) by calling a directive to watch before I bind the data to View model. Factory To Monitor Changes This is easiest and effective way because of these reasons : 1) I just need to call a Trigger Method with scope which should be monitored 2) Once the data is retrieved from Ajax call , I just Initialize the data 3) If there are any changes to bound data on the form and user tries to navigate to another page, I get Confirm box on the...

Thoughts on C# 7.0 Local Functions. Potential Features - Local Functions Frankly, when I first tried this, I thought that it's just a nice and compact way of defining local helpers. In fact, it's much more interesting and useful feature. Today I'm going to explore and explain it in more details. Let's  start with a brief overview of the current situation. Before Local Functions Private methods The first option that existed in C# 1 is having a private method. That’s a clean and simple solution. It has few issues, though. PrintMe might have no sense outside of ThatTime method, but it’s accessible for every other method inside the class. It will be taken into account by IntelliSense. Func and Action We can try to hide our helper inside the scope of ThatTime method by converting it to Func<int, string>: Any disadvantages ?? Yep, a lot. The call is unnecessary expensive: it will produce  more ...
