Hello, so I've been experimenting with the framework and I tried
to implement a game that has more than two windows.
The first window is the main game and the second window is a
smaller one with the various commands you can select.
So I tried to render sprites onto the first window and the
it's seems that next block is execute even if is rs.next() is
false:
writeln("rs.next()-->", rs.next());
if(!rs.next()) //if user do not in DB
{
// is execute even if rs.next() is false
writeln("Executed, but rs.nst was set to false");
}
The output:
rs.next()-->false
Executed, but rs.nst was

I would like to use the last syntax, but with an alias.

Yes, there was issue with host name, but it's do not solve
problem. Second DB have same fields and I still getting false
instead moving into while loop

Don't piece queries together without escaping the dynamic parts.
Imagine what happens when the user enters an apostrophe in

Looks like an AliasSeq can contain a template identifier too. So should I
understand that AliasSeq in general can refer to any identifier and any
value? Hitherto I thought it was any *type* and any value...

Hello. Re my posting just now re AliasSeq being able to contain a template
identifier too, I wonder whether it is possible to have a std.traits
template to identify whether something is a template or not?
In connection with this, while is() is there to determine whether something
is a type or
By putting it in the top level. I believe this is intentional
but I don't remember the reasoning.

Hello guys,
I am still uncertain how to do it right when it comes to lambda
functions. For instance: how do I multiply all the elements in an
array ?
int product(const ref int[] arr){
int p = 1;
foreach(i;arr)
p*=i;
return p;
}

If you are looking for the functionnal way I'd advise that you
start by
looking up three functions in a language-agnostic way: filter,
map and

A good post overall but you got reduce wrong. In D, reduce
