  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

  • Parameterizing a SQL IN clause?

    - by Jeff Atwood
    How do I parameterize a query containing an IN clause with a variable number of arguments, like this one? select * from Tags where Name in ('ruby','rails','scruffy','rubyonrails') order by Count desc In this query, the number of arguments could be anywhere from 1 to 5. I would prefer not to use a dedicated stored procedure for this (or XML), but if there is some fancy SQL Server 2008 specific way of doing it elegantly, I am open to that.

    How to create a new data type which to can check/validate its schema when is created a new variable (of that type)?

  • Storing a type in C++
