Hi...
I want to send over tcp/ip some data, i have the data in hexadecimal, and when i try to send it, i have a few problems.
I give the data as a parameter to the program... argv[1]
Example of argv[1] = "0518EF5600AD"
This is hexadecimal data (05 18 EF 56 00 AD)
The main problem for me is the Send function...
Code:
int send(
__in SOCKET s,
__in const char* buf,
__in int len,
__in int flags
);
How can i send this data if the 2 parameter in the send funcion is a CHAR... and i need to send some null strings like Hex(00)...
I would like to send this:
Code:
unsigned char info[] =
{
0x84, 0xFA, 0xEF, 0x00,
0x01, 0xEF, 0x05, 0x31,
0x01, 0x01, 0x01, 0x20,
0xF9, 0xC7, 0xDC, 0x79,
0x80, 0x99, 0xF1, 0xF2,
0xF3
};
I been trying with some like this:
Code:
string sento;
sento=HexToAscii('02 01 EF 05 31 00 01 00 20 F9 06 02 01 EF 05 33')
nBytesSent = send(Socket, sento.data(), sizeof(sento), 0);
And works, but the other side, all the hex data over 79 change... EF >> 6F... check this:
send: 02 01 EF 05 31 00 01 00 20 F9 06 02 01 EF 05 33
recv : 02 01 6F 05 31 00 01 00 20 79 06 02 01 6F 05 33
...dunno why. With C_Str si the same. I did the same code in Delphi and works perfect... but in C++ i cant. The problem is when i send !
How can i send the value of "info[]" or correct my program?
Stopped working!
So I had to change some stuff, none of it major. Stuff like the extension_dir and such. BEFORE I did much, I had that code working fine. Then I did some changed... well a lot of changes that I cant
