C++ A Few Errors

Expand Post »
When i compile this code i get a few errors (i guess are simple for you guys)

C++ Syntax (Toggle Plain Text)
  1. void WriteMem(DWORD MemOffset, DWORD DataPtr, DWORD dataLen) {
  2.   { DWORD OldProt;
  3.   VirtualProtect((void*) MemOffset, dataLen, PAGE_EXECUTE_READWRITE, &OldProt); 
  4.   RtlMoveMemory((void*) MemOffset, (const void*) DataPtr, dataLen);
  5.   VirtualProtect((void*) MemOffset, dataLen, OldProt, &OldProt); 
  6.   }
  7.   void EnableHack(BYTE* AddrToChange, BYTE* To, DWORD len); {
  8.    for(DWORD i = 0; i < len; i++) 
  9.     WriteMem((DWORD)AddrToChange+i, (DWORD)To+i, 1); 
  10.   }

Re: C++ A Few Errors

that's what happens then you fix something :cheesy: look at the first eror message and try to find out why MemOffset is undefined. Where did you define it? It must be in one of two places: (1) a global variable, or (2) a variable declared inside the function in which its used.

Fix one error and it may solve several error messages.

Re: C++ A Few Errors

First you have this:
C++ Syntax (Toggle Plain Text)
  1. void WriteMem(DWORD MemOffset, DWORD DataPtr, DWORD dataLen) {
  2. ...
  3.   }
  4.   void EnableHack(BYTE* AddrToChange, BYTE* To, DWORD len); {
  5.    for(DWORD i = 0; i < len; i++) 
  6.     WriteMem((DWORD)AddrToChange+i, (DWORD)To+i, 1); 
  7.   }
and the recomendation was

>> void EnableHack(BYTE* AddrToChange, BYTE* To, DWORD len); {
remove the semicolon
Now you have:
C++ Syntax (Toggle Plain Text)
  1.  
  2. void WriteMem(DWORD MemOffset, DWORD DataPtr, DWORD dataLen); {

What changed in the line (and more importantly, why did it change?)

Re: C++ A Few Errors

and first you have this:

C++ Syntax (Toggle Plain Text)
  1.  
  2.   void EnableHack(BYTE* AddrToChange, BYTE* To, DWORD len); {
  3.    for(DWORD i = 0; i < len; i++) 
  4.     WriteMem((DWORD)AddrToChange+i, (DWORD)To+i, 1); 
  5.   }
and now:
C++ Syntax (Toggle Plain Text)
  1.  
  2.   void EnableHack(BYTE* AddrToChange, BYTE* To, DWORD len);
  3.    for(DWORD i = 0; i < len; i++) 
  4.     WriteMem((DWORD)AddrToChange+i, (DWORD)To+i, 1); 
  5.   }
which are both wrong. Is this the implementation of the function or are your just trying to call it and is it part of something else?

Re: C++ A Few Errors

ok, then you should remove the semicolon as Ancient Dragon allready said.


C++ Syntax (Toggle Plain Text)
  1.  
  2.   void EnableHack(BYTE* AddrToChange, BYTE* To, DWORD len) 
  3.   {
  4.    for(DWORD i = 0; i < len; i++) 
  5.     WriteMem((DWORD)AddrToChange+i, (DWORD)To+i, 1); 
  6.   }

And in your other function too offcourse, as WaltP pointed out.
