I have an ArrayList containing Objects that have a date value.
Now I want to manage to create a new ArrayList for each year that contains all the Objects from the main ArrayList that have the same year in their date Value.
So all Objects from 2010 go in one List, all from 1999 in another.

Hi,

Instead of executable code all it does is create files that don't do anything, even if the files are made executable.
TARGETS = load list show add delete btree
all: $(TARGETS)
%: %.cpp
g++ $< -g -o $@ -MM -MF [email protected]
sed "s/$@\.o:/$@:/" [email protected] > [email protected]
-@rm [email protected]
DEPS=$(TARGETS:%=%.d)
-include $(DEPS)
I started with the standard scriptaculous drag and drop tree, and that all works fine.
Then started implementing this:
http://www.artweb-design.de/2008/5/30/scriptaculous-sortabletree
which gives a good drag and drop tree
Where I am stuck is how to get serialize the tree (unordered list)? It's not in a form, and I can't find a way to serialize it to move onto setting up the AJAX update.
I have an ASP pg with a formview list control on it that hooks up to a sql database customer table
I want to access the customer name outside the form.
How do I:
A) access the bound text box in the form view template? Something like Text1.text=formview1.customername.text (that doesn't work but that's the kinda thing)
B) access the database field in the table that the sqlsource connects to to feed the formview
Really appreciate the help. I bet it's easy to do but I'm just not getting there.
I'm using a list of siteMapProviders in my web.config file.
To retrieve these values in code, I need to specify the names in strings.
Understandably, these is always a mismatch at runtime.
Is there a way to return a strongly typed enum vlaues of these?
Tie::Hash has these:
sub FIRSTKEY { my $a = scalar keys %{$_[0]}; each %{$_[0]} }
sub NEXTKEY { each %{$_[0]} }
NEXTKEY takes two arguments, one of which is the last key but that arg is never referenced?
The various Tie docs don't shed any light on this other than this in perltie:
my $a = keys %{$self->{LIST}}; # reset each() iterator
looking at the doc for each doesn't add to this.
What's going on?

From what I understand about apply, it unpacks a list and turns the elements into arguments for a function.
I see that (apply + [1 2 3]) works as expected, i.e: it's equivalent to (+ 1 2 3).
Why then is (apply or [true false]) invalid? Isn't it equivalent to (or true false) ?
Hey guys,
I'm looking for a simple solution to place a draggable element inside of a box container. When the user begins to interact with the draggable, the draggable element should remain constrained to a circular shape, within the container.
At a complete loss as to how I should accomplish this.
Thank you! :-)
Additional:
Box container would be 100 pixels wide and tall
Draggable would be 20 pixels wide and tall
http://tool-man.org/examples/dragging.html This is on the TODO list, but of course this site is no longer maintained
This is my function:
(defun MyFunction(input)
(let ((NEWNUM (find input num)))
(if (find input num) //if this
(setq num NEWNUM) (FUNCT2) //then execute both of these
(list 'not found)))) //else output this
So after the if statment I want to be able to execute (setq num NEWNUM) and (FUNCT2). One to set a new variable and then the other to call a function. Any ideas on how to do this?
In VB.NET type this on a new line:

Shouldn't a dropdown picklist of enum values appear?
It used to! I miss it!
Of course, this is just one example where an enum pick list does not appear where it did before.
Can anyone defend this or is it a bug?
