Consider the following:
Can you see why the above just cause a client of mine SIGIFICANT money?Code:public class SomeClass()
{
protected virtual void SpecialWorkerMethod()
{
throw new Exception("Derived Class must Implement this Method");
}
}
hint: The direct cause is directly related to C#, but the ROOT cause can happen in any language.
I'm guessing that this issue didn't show up until run time.
Restructuring the code using interfaces (and maybe constraints) probably would have allowed catching the problem during compile time.
1) Yup, right hile rinning for the client.Quote:

I'm afraid I don't know, but I'd like to find out. What was the problem?Quote:

We all make mistakes occasionally... don't we ? :D

If a mistake costs $3 million dollars (yes, actual amount), then SOMEONE is going to lose their job.Quote:

No kidding ? How did it sum up to $3 million ?? I mean did they loose future sale or they lost agreement or something ?Quote:

My client had a delivery commitment. A missed milestone invoked a thirty day penality (they met with their client one per month). When the program was being demonstrated, and blew up, it was deemed "not ready for user acceptance", and the commitment was declared "not met".Quote:

Yikes, I wouldn't wanna have had that guys job... I use C# all the time and I thought it was a hefty method simply because of the exception being thrown and bubbling up the call stack. Also, if it had to be implemented, why didn't he use an interface?
I work for a small company doing all their software, I love my job, but when software development starts to become like boot camp thats when I pack my bags, lol.
You'll never earn very much then... the toughest jobs I've had have also the highest paid.Quote:
