C++ nop Address

Hi all,

I would know how i can nop a address ?

Via Visual C++ 6

Thank from advance

Use WriteProcessMemory() with the address you want and 90 for each byte you want to nop.

can you give an example of this code pls ?

Pretty simple.

Code:

WriteProcessMemory(hProcess, 0xADDRESS, 0x90, 1, NULL);

That would nop the code at 0xADDRESS (obviously not a real address, replace with the address of the code you want to nop).

hProcess is a handle (HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE,PROCESS_ID)) to the process of the game.

0x90 is the hex code for the nop instruction.

1 is the length of the code to write (nop = 1 byte).

NULL is given because we don't care how much code is written, supply this with a pointer to a DWORD if you want to know how many bytes were actually written (error checking, etc).

If you still don't understand, I think you should get a firmer grasp of the Win32 API.

Note that most funtions are not 1 byte most of the time so you may need to do this byte nop[]={0x90, 0x90, 0x90, 0x90}; this will nop 4 bits...

This works to ...
i think

Code:

unsigned long ulStamina = 1120403456;
memcpy_ex( ( void* )0x7F1110, &ulStamina, sizeof( unsigned long ) );

umm no that will not work....there is no memcpy_ex( you would need ti wright your own call..Next time coping find where the call is to and copy that plus that would have set it to 1120403456 not nop it..
