hello guys,

i developed this to help me creating my C++ projects: a header!

this is my first one, and till now it works fine.

it already include <windows.h> , <iostream> and <psapi.h> (must to it works)

so u can create very tiny codes like this:
Code:


#include <hack.h>
using namespace std;

int main()
{
    int value;
    int address;
    while (AttachToProcess("MSACCESS.EXE"))
    {   
         cout << "Enter address to modify (decimal): ";
         cin >> address;
         cout << "Enter value: ";
         cin >> value;
         Write(address,value);
         system("PAUSE");
         }
    }


the header have the functions:

Code:

void   Clean                   () {system("CLS");}          // To clean the screen ^^
int    P                       (int address,int offset);    // For pointer addresses, using read(), eg.: P(P(pointer,offset1),offset2) = [[pointer]+offset1]+offeset2
bool   AttachToWindow          (char* name);                // Attach to the desired window name, return TRUE if sucess else FALSE
bool   AttachToPID             (int PIDtoLook);             // Attach to the desired PID, return TRUE if sucess else FALSE
bool   AttachToProcess         (char* pName);               // Attach to the desired process, return TRUE if sucess else FALSE
void   ShowProcessList         ();                          // Show a list of running processes
void   Write                   (int address,int value);     // Change the value in address to value
int    Read                    (int address,int size);      // Return the value in address; size = 1,2,4 bytes value
void   ReadString              (int address,int size);      // will store a string present in address to ReadStringValue
char   ReadStringValue[512];                                //
void   ExitProcess             ();                          // Exit the opened process


as u can see theres still allot of things to work on, thats why its on ALPHA version.

remember if u are using any IDE thats not MSVC: link libpsapi.a so it works fine.

as aways:
comments, suggestions, bugs, etc are welcome!

edit----

removed the search function, since it wasnt working as it should.
im studying caching to improve it.

THE HEADER : http://ifile.it/w7s8vxp

note: as the file was too small to upload i add a small useless file on it.

don't allocate such a giant chunk on the stack, you are cruising towards trouble:
Code:
int FoundAddress[1024];
char ReadStringValue[512];


allocate the memory yourself.

and what's the difference between the Read() and ReadString() functions? their prototype is the same. Why is it not just one function?

Read() returns an number of 1,2 or 4 bytes.
ReadString() saves the string of desired size on ReadStringValue

like reading / writing a struct.

well, i gave the functions, i bet u can do what u want to using loops etc.

ofc it would be nice to implement a byte to byte writter/reader to/from an array.

ty for idea. going to release it in next ver.

more ideas are welcome^^

Just a few quick tips, both of the following are horrible programming practices. System() is "system specific" and therefore drops the portability of the program. There are better ways to do the same thing.

----------------------------------------------------

Code:
void   Clean                   () {system("CLS");}          // To clean the screen ^^


Replace that with something like this:

Code:
void Clean() {
for(int i = 0; i <= 50; i++) {
cout << "\n";
}
}


-------------------------------------------------------------

Code:
system("PAUSE");


and a replacement for this:

Code:
cout << "Press enter to continue";
cin.get();


--------------------------------------------------------------

All in all, use system(); as little as possible. Something that works well on Windows may not work elsewhere if you go that route. There are alternatives for what you want to do using system() and they are typically easy enough to do. The "cleaning" method will throw out a whole bunch of lines and push your text to the very bottom of the screen and get rid of all of the lines before it, the pause method will wait until the user presses enter and as soon as they do it will continue on.

TL;DR: Copy and paste the codes, they are better programming practice.

Spamming the console with \n to "clear" it isn't better practice lol..

On Windows users can use the standard API for consoles:
- GetStdHandle
- GetConsoleScreenBufferInfo
- FillConsoleOutputCharacter
- SetConsoleCursorPosition

Or using:
- std::system( "cls" );

(I recommend not using std::system at all on Windows, its bloated.)

On POSIX systems you can do things like:
- system( "clear" );
- cout << "\f";

Other methods:
printf("\033[2J\033[1;1H");

// all three lines
fputs("\033[A\033[2K\033[A\033[2K",stdout);
rewind(stdout);
ftruncate(1,0);

I getting error on windows 7, microsoft visual studio ( C++ )

I create simple program like this:

Code:
#include <hack.h>
using namespace std;

int main()
{
    int value;
    while (AttachToProcess("Minesweeper.exe"))
    {   
         cout << "Enter value to search: ";
         cin >> value;
         Search(value, 4, 1, 0x10112600, 0x1013E800);
         system("PAUSE");
         }
    }

Since you use common names for functions (read, write, search,etc), it would probably be a good idea to wrap your header in a namespace.

You can ignore the advice to avoid stack allocation. A few K on the stack is no big deal.

So exactly why do you think stack probes are necessary for stack allocations over the page size again ?
