Writing your own STL Container
...whenever I make a container, I test with a class more or less like this:
#include <cassert>
struct verify;
class tester {
friend verify;
static int livecount;
const tester* self;
public:
tester() :self(this) {++livecount;}
tester(const tester&) :self(this) {++livecount...
Insert results of a stored procedure into a temporary table

You can use OPENROWSET for this. Have a look. I've also included the sp_configure code to enable Ad Hoc Distributed Queries, in case it isn't already enabled.
CREATE PROC getBusinessLineHistory

BEGIN
SELECT * FROM sys.databases
END
GO
sp_configure 'Show Advanced Options',...

Converting Secret Key into a String and Vice Versa
...Spec(decodedKey, 0, decodedKey.length, "AES");
For Java 7 and before (including Android):

grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"

What's the meaning of exception code “EXC_I386_GPFLT”?
...cOSX10.9.sdk
$ find usr -name \*.h -exec fgrep -l EXC_I386_GPFLT {} \;
usr/include/mach/i386/exception.h
^C
$ more usr/include/mach/i386/exception.h

Separating class code into a header and cpp file
...ration goes into the header file. It is important that you add the #ifndef include guards, or if you are on a MS platform you also can use #pragma once. Also I have omitted the private, by default C++ class members are private.

#define A2DD_H

What is the default height of UITableViewCell?
...MikeyWard: You probably figured this out already, but the 1px separator is included in the height. It actually covers the bottom-most content of the cell.
