here's my pointer reader :

Code:

//Reads a Pointer
__inline ULONG_PTR ReadPointer(ULONG_PTR* ulBase, INT nOffset)
{
if ( !IsBadReadPtr((VOID*)ulBase, sizeof(ULONG_PTR)) )
if ( !IsBadReadPtr((VOID*)((*(ULONG_PTR*)ulBase)+nOffset), sizeof(ULONG_PTR)) )
return *(ULONG_PTR*)((*(ULONG_PTR*)ulBase)+nOffset);
return 0;
}
// Read Double Pointers
__inline DOUBLE ReadDouble(ULONG_PTR* ulBase, INT nOffset)
{
if(!IsBadReadPtr((VOID*)ulBase, sizeof(double)))
if(!IsBadReadPtr((VOID*)((*(ULONG_PTR*)ulBase)+nOffset), sizeof(DOUBLE)))
return *(DOUBLE*)((*(ULONG_PTR*)ulBase)+nOffset);
return 0;
}

when i do this :

Code:

SetDlgItemText(hWnd, IDC_MP, _itoa(ReadDouble((ULONG_PTR*)StatBase, StatMP), buf, 10));

i am get an warrning :

Quote:

warning C4244: 'argument' : conversion from 'DOUBLE' to 'int', possible loss of data

and the reader not works .

HELP>.<

use that function to format your double as a string. at the moment you're trying to convert it as an int when it is a double _itoa is for integers

You won't be able to itoa a double..yes it is it.

Since you're using C++, you should probably make use of some of its features.

Code:

#include <windows.h>
#include <iostream>

using namespace std;

template <typename T>
bool CrashProgramRandomly(const T *ptr) {
return ::IsBadReadPtr(ptr, sizeof(T)) ? true : false;
}

template <typename T>
bool Read(const T ** base, unsigned int offset, T & out)
{
if(!CrashProgramRandomly<const T*>(base)) {
   if(!CrashProgramRandomly<T>((const T *)((char*)(*base) + offset))) {
      out = *(T*)((char*)(*base) + offset);
      return true;
   }
}
return false;
}

int someNumber = 1337;
int magicNumber = 42;

int main()
{
const int *somePtr = &someNumber;
int anotherNumber;
if(Read(&somePtr, sizeof(int), anotherNumber)) {
   cout << anotherNumber << endl;
}
return 0;
}

(You should probably replace those C style casts with proper C++ casts. I didn't because it would make the example look like a cluster fuck, and I'm lazy.)

Flyte: The program clearly has a dialog as its GUI, and that is his main issue. Can you help him with that instead of unnecessary examples?

It's his job to impart wisdom. See here : http://forum.cheatengine.org/viewtopic.php?t=479428&postdays=0&postorder=asc&start=0

Despite Flyte having been given tens of thousands of dollars in scholarship money, numerous awards, and even attending a university that essentially pays him to go there, he is still full of shit. He has no interest in helping people, only showing off what little he knows.

OP : here is an example how to convert a hex address for example :

Code:

swprintf_s( szAddress, _countof( szAddress ), _T("%08X"), i );

Same principle applies

Clearly his issue is not understanding the difference between primitive types.

<nolyc> http://adrinael.net/youreright.jpg

No one else here seems to be capable of doing it.

Giving him C code when he is programming in C++... see above.

I don't see how you can criticize other replies to his problem, if you yourself have not given a valid response.

Are you blind.. ? That clearly is his issue

There are many ways to do this. The easiest would be to use boost::lexical_cast.

His problem is not related to his GUI at all. Replace SetDlgItemText with any function that wants a 'const char *' and he will end up with the exact same error.

I reiterate: his problem is not understanding the differences between the primitive types.

With this, you can just cast a double right to a char*?

I'll have to start reading more about boost APIs.

Code:

boost::lexical_cast<std::string>(doublevalue)

No, you would cast to std::string then use string::c_str(). I would hope something this simple would be obvious.
