SQL Server String or binary data would be truncated
...nd do not care if it is not the case, then another solution is to forcibly cast the source query columns to their destination length (which will truncate any data that is too long):
Select Cast(TextCol1 As varchar(...))

How can I iterate over an enum?
...
for ( int fooInt = One; fooInt != Last; fooInt++ )
{
Foo foo = static_cast<Foo>(fooInt);
// ...
}
Please note, the enum Last is meant to be skipped by the iteration. Utilizing this "fake" Last enum, you don't have to update your terminating condition in the for loop to the last "real...
What would be C++ limitations compared C language? [closed]
..._t) );
To make it compile as C++ you have to write:
foo_t* foo = static_cast<foo_t*>( malloc ( sizeof(foo_t) ) );
which isn't valid C any more. (you could use the C-style cast, it which case it would compile in C, but be shunned by most C++ coding standards, and also by many C programmers...

C# vs Java generics [duplicate]
...ompiled classes are not actually generic. They compile down to Object and casts. In effect Java generics are a compile time artifact and can easily be subverted at runtime.
C# on the other hand, by virtue of the CLR, implement generics all they way down to the byte code. The CLR took several b...
converting double to integer in java

is there a possibility that casting a double created via Math.round() will still result in a truncated down number
No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal plac...
What does void mean in C, C++, and C#?
...
Not disagreeing, but an additional use of void is in the "cast to void" trick to suppress warnings for unused values. It's a bit of a stretch since it doesn't really correspond with how the compiler interprets things, but you can interpret that to mean "I'm using this value to do no...
convert an enum to another type of enum
...), value.ToString());
If you mean by numeric value, you can usually just cast:
Enum2 value2 = (Enum2)value;
(with the cast, you might want to use Enum.IsDefined to check for valid values, though)
