 |

Good evening Cheat-Engine-Community!
How can I convert something like this:
 (Text in a TextBox) to an array?
(Equal to this:  )?
Thanks in advance! (And sorry, if this has been asked before..)

You could do something like this:
| Code: |
#include <Windows.h>
#include <iostream>
#include <sstream>
#include <string>
std::string HexStrToDefine( const std::string& strInput )
{
std::stringstream ss;
ss << "unsigned char m_DataOutput[] = { ";
for( int x = 0; x < strInput.length(); x += 3 )
{
ss << "0x" << strInput.substr( x , 2 );
if( (x + 3) < strInput.length() )
ss << ", ";
}
ss << " };";
return ss.str();
}
int __cdecl main( int argc, TCHAR* argv[] )
{
std::string strInputString = "DE AD BE EF";
std::string strOutputString = HexStrToDefine( strInputString );
return 0;
} |
This has no error checking and requires your bytes to be 2 chars each.
So you cannot do things like:
DE AD B E A F

Thanks, but as I interpret this piece of code, it takes an std::string and returns an std::string
Kind of useless for me..

Try this:
c_str()

Take in the string
Create a pointer to an array of char's,
Fill said array with "0x" + the parts from your string
return pointer
I could be totally fuckin wrong though, nomsayin'
Edit: I mean in that case you at least have a handle on it...
as far as a direct conversion..Im too high to help with that atm, will provide code later though if you ask for it

The way you presented the thread made it seem you wanted the string version and not the ability to use the hex. Here is a way I tossed together, minimal error checking and it can throw exceptions. You are also responsible for freeing the pointer when you are done with it.
| Code: |
#include <Windows.h>
#include <algorithm>
#include <string>
unsigned char* HexToData( const std::string& strInput )
{
int nSpaces = std::count_if( strInput.begin(), strInput.end(),
[](const char c) { return ( c == ' ' ); }
);
char* pszInput = (char*)strInput.c_str();
char* pszNext = NULL;
char* pszToken = strtok_s( pszInput, " ", &pszNext );
if( pszToken == NULL )
return NULL;
unsigned char* pszData = new unsigned char[ nSpaces + 1 ];
while( pszToken != NULL )
{
unsigned char chData = (unsigned char)strtol( pszToken, NULL, 16 );
*pszData = chData;
++pszData;
pszToken = strtok_s( NULL, " ", &pszNext );
}
pszData -= ( nSpaces + 1 );
return pszData;
}
int __cdecl main( int argc, TCHAR* argv[] )
{
std::string strInputString = "DE AD BE EF FF F";
unsigned char* lpData = HexToData( strInputString );
if( lpData != NULL )
delete lpData;
return 0;
}
