if you want to use X objects as keys in hashmaps, you don't have to implement Compareable (that's what you do for treemaps).

In hashmaps, the keys are considered equal according to the values of...

You may also have a look to the implementation of the Boost C++ library :

c= firstNameAsEntered.charAt(0)

This will surely fail if the character string is empty ...

first check the length of the string, before translating the first letter into uppercase, and maybe...

thx, i'll have a look to these books.
... it seems to be a quite annoying technology, though

I'm glad to see that you remembered of me :)
I'm happy to see you again, too

Is there a simple way for writing ActiveX components with minGW ? (ie without using activeX or ATL) ?

I have to write an activeX but a don't want a buy a visual studio licence just for this <:)

2) MAC address and MAC Frames are two different things. The Media Access Control protocol (IEEE 802.x) defines a way for...

When you use win32-specific code, you have to know about the different windows API's specific symbol.

Maybe you forgot to include the right header file, at the beginning:

in C, functions are defined just like variable.

The adress of a function can be assimiled to its adress in memory, so the following code is valid :

#include <stdio.h>


void something()

euhh.. you might be using a broken computer

In all the cases, your code always prints 1.

1) i++/i = 10/10, and afterwards i=11

2) i/++i = 11/11 and afterwards i=11

3) i++/++i = 11/11,...

I'm trying to get a code in a DLL runned each time a program is launched.

I would work better if your code was in C++, and not in CSharp....

gaim is compatible with the aim protocol, that's why it has been written for. The advantage of using the libgaim dll is that you will not require user of your program to install a 3rd party program...

I don't think that the AIM software enables user to force a message to be sent using the commanline, or ShellExecute action. You may use instead an external C library that allows to do such things.

The 'far' keywork only makes sense under DOS, and is useless with minGW.

Do you know how to read the activity of a serial device (COMx) under windows ?
I would like to write a program that could sniff the serial/ port.

is it what you needed ?

when you write '-1', you do not write the VALUE -1, but the character string { '-', '1' }
