Problem with VirtualProtect

[KinGalaxy 0]

Hello m8,

I have a problem with the VirtualProtect function...

I wrote this in Vc++ 6.0:

Invisibility function

memory();
BYTE Nop[] = {0x1C};
asd((void *)0x505C58,(void *)&Nop,sizeof(Nop));

That's "asd" function:

void asd( void* pxAddress, void* pxBuffer, int size )
{				  
unsigned long Protection;		
VirtualProtect((void*)pxAddress, size, PAGE_READWRITE, &Protection);
memcpy((void*)pxAddress, (const void*)pxBuffer, size);
VirtualProtect((void*)pxAddress, size, Protection, 0);
}

 

Compiling give me 0 errors, but if I open mi exe and press the button i recive this error:

 

What is the error/s?

Thanks a lot

why "memory()"

 

do you inject a dll into warrock and then executing the code? if yes, there should be no problems.

if no.. you are patching your own process

the screens looks like a mfc.exe memcpy writes only to the own process!!! on d3d hacks this will work but not in an exe file...

 

you need to use writeprocessmemory but the new punkbuster version is blocking this now...
