Hey,

I'm trying to in this array:
Code:
char loginpacket_end[23] = { 0x00, 0x2B, 0x21, 0x5A, 0x22, 0x58, 0xF2, 0xE0, 0x0E, 0xB4, 0x00, 0x00, 0x00, 0x00, 0x3C, 0xD4 , 0x00 , 0x00 , 0x00 , 0x00 , 0x02 , 0x00 , 0x00 };


Compiler says:
Code:
c:\dokumente und einstellungen\reakw0n\eigene dateien\visual studio 2008\projects\rnd\rnd\main.cpp(102) : warning C4309: 'initialization': Shorted a constant value
c:\dokumente und einstellungen\reakw0n\eigene dateien\visual studio 2008\projects\rnd\rnd\main.cpp(102) : warning C4309: 'initialization': Shorted a constant value
c:\dokumente und einstellungen\reakw0n\eigene dateien\visual studio 2008\projects\rnd\rnd\main.cpp(102) : warning C4309: 'initialization': Shorted a constant value
c:\dokumente und einstellungen\reakw0n\eigene dateien\visual studio 2008\projects\rnd\rnd\main.cpp(102) : warning C4309: 'initialization': Shorted a constant value

(translated)

And line 102 is for sure the array line, and also when I send the packet it's sending like nothing.

I asked Lurc about that and he threw this line in a project and it compiled fine. What's the problem there?

Thanks!
But can you explain why my array doesn't work?

Edit: When I do printf with that it doesn't print anything... Confused

The first char null terminates it...

Ohwell yea Cx.
The problem was I used a STRING and merged all arrays witht he += operator, but it didn't terminate on 0x00, it just ignored it.
Now I'm using sprintf_s().

But when I send the packet, I need to get the length of the char-array. But since strlen() ignores 0x00, what should I use instead of it?

Edit: Okay got it :>

Thanks everyone.
