Ok, thanks for answer, it was just error in my class (i used another one from forum, i will check it later why my func failed)

Anyway i wanted try (for fun) try recv packet too, is it much harder?
I found it:

Code:
0052EA93   8B06             MOV EAX,DWORD PTR DS:[ESI]
0052EA95   50               PUSH EAX
0052EA96   68 A8796100      PUSH nostalex.006179A8
0052EA9B   BA 4CFE5200      MOV EDX,nostalex.0052FE4C                ; ASCII "info"
0052EAA0   8BC3             MOV EAX,EBX
0052EAA2   E8 6D71FFFF      CALL nostalex.00525C14
Code:
0052E4E7   A1 C0816700      MOV EAX,DWORD PTR DS:[6781C0]
0052E4EC   8B00             MOV EAX,DWORD PTR DS:[EAX]
0052E4EE   8B58 34          MOV EBX,DWORD PTR DS:[EAX+34]
But both code above looks valid. :/

For recv:
Code:
VOID RecvPacket(CHAR* _i8_packet)
{
	DWORD _i32_RecvPacketFunc = 0x525D30;

	__asm
	{
		mov eax, dword ptr ds : [0x6781BC]
			mov eax, dword ptr ds : [eax]
			mov eax, [eax + 0x34]
			mov edx, _i8_packet
			call _i32_RecvPacketFunc
	}
}
btw. Address on my code (code from OMG thread) is invalid xD

@iAtrix
I had this code too from the olly but still don't know that call adress (i thought that its' 00525C14 but not)

For recv function you have to look deeper in the function.
It's harder to find as sendPacket.

@WalrossGreat, you should study the memory before than try it..
Useless a C. & P. if you don't know how pointers are working! And you don't, sure 101%
07/27/2015 21:43 WalrossGreat#21
@*-OMG-* The one thing what i copied from this thread is the send packet call adress.
What you mean by don't know how pointers are working? Pointers strore information where the variable/element is stored in memory, don't they?
07/28/2015 02:02 *-OMG-*#22
@WalrossGreat, if you were are able to work on the memory then you was not asking for it cuz pretty simple..

MOV EAX, DWORD PTR DS : [0x6781C0] <-- Nothing more than a pointer read! [eax = *(DWORD*)(0x6781C0)]

Man actually i did my own class and it's working fine, as i said at second page on this thread, i don't need copy paste your code, i thought that it was the problem with the __asm code, but no it was probably something bad with my class
07/28/2015 14:28 *-OMG-*#24
Your class ?

Code:
class PacketString 
{
public:
	char char_t[256];
	PacketString(char* str)
	{
		char* str2 = str;
		int len = strlen(str2);
		memcpy(char_t, str2, len);
		char_t[len] = 0x0;
	}

	char* _return()
	{
		return char_t;
	}
};
Do you mean copy & paste from here ?

No :)
Man the code (from link and my) do probably the same, so it realy ovbius that it looks similar, or no - i know all the pastebins subpage.

If you really want know i was modeling on it: [Only registered and activated users can see links. Click Here To Register...]

@WalrossGreat, You are so stupid to don't know that AnsiString have a weight (similiar ? are you sure ? ahah), back to study instead leech.

I did support you but today i understand that you're worth nothing.
07/28/2015 16:26 WalrossGreat#27
@*-OMG-*
I never saw a man so filled with venom like you. Yes you supported me a lot (nothing) unless you named your supporting flaming me (I don't talking only about this thread).

For moderators: Please close this thread. Thanks who every person who helped. Topic is solved and now there is only offtopic.
@UP
If you still want flame me please do it on PM but as i see:

PS. You think that i'm too stupid to know that AnsiString have a weight (lol), but i think that you are too stupid to talking with other peoples

NosTale uses AnsiString of delphi, lol. ;)
Or i did unterstand something wrong.

Yeah, you are right. Nostale is written in delphi and uses AnsiString.. Visual studio has not the support for it but.. You can write a suitable class ending the string by 0 and adding, at the start, the string weight (usually 1) and length.

32bit | string weight
32bit | string length
8bit* | string buffer
07/29/2015 00:33 Trollface-#30
Why don't use the class directly in nos? so you dont need to write a class which already exists.
