variable Bytes question

[iwdu15]

hi, to get the bytes sent by a socket, in VB a simple local variable like
below was used

Dim recv as Byte()

how can i do that in C++...this is what i am trying now

Byte * rec[] = new Bytes;

but i get these errors:

x:\User\FinalPr oject\Battleshi p\NewGame.h(180 ): error C2691: 'unsigned char
__gc *' : invalid type for __gc array element
x:\User\FinalPr oject\Battleshi p\NewGame.h(180 ): error C2061: syntax error :
identifier 'Bytes'

how can i get the bytes variable so i can receive the text sent by the other
connected socket? thanks

this will give you a simple array of bytes.

Byte test[] = new Byte[1];
Byte test2 = 'A';

test[0] = test2;
kind regards,
Bruno.

100 bytes? Bruno's example was a one byte array. But anyway, the trick
to not overflowing an array is to not read more bytes than can fit in it.

if possible, always work with a fixed buffer size.
this will be more performant than always allocating and de-allocating buffers.

i don't know what you intend to send, but if it is not too much, just
allocate an array that will always be big enough. use a 1 MB buffer if that
solves you problem.
IMO that is a much better solution than having to manage variable length
buffers.

having to add xxx lines of memory management code to save a few bytes of
data is not worth it in most cases.
but in all cases, check the array size before you write data to it.

kind regards,
Bruno.
