MemoryReading with c++

You should use a template so you can have one function to write to any data-type

Templates are ftw.

Then again, why would we listen to you, you're a "noob", remember?

True.. but then again.. who takes offense to leachers these days?

So i went ahead and whipped this up in 10 minutes, should work to however you want it to.

class CMemoryReader
{
public:
    
    template <class T>
    bool Read( DWORD dwOffset, T& TSave )
    {
        if ( !Un****( dwOffset, sizeof( T ) ) )
            return false;

        TSave = *(T*)dwOffset;

        Re****( dwOffset, sizeof( T ) );

        return true;
    }
    
    template <class T>
    bool Write( DWORD dwOffset, T TData )
    {
        if ( !Un****( dwOffset, sizeof( T ) ) )
            return false;

        *(T*)dwOffset = TData;

        Re****( dwOffset, sizeof( T ) );

        return true;
    }

    //-----------------------------------------------------------

    bool Un****( DWORD dwOffset, DWORD dwSize )
    {
        return VirtualProtect( (LPVOID)dwOffset, dwSize, PAGE_EXECUTE_READWRITE, &m_dwOld );
    }

    bool Re****( DWORD dwOffset, DWORD dwSize )
    {
        return VirtualProtect( (LPVOID)dwOffset, dwSize, m_dwOld, &m_dwOld );
    }
private:
    DWORD m_dwOld;
};

    CMemoryReader MemoryReader;

    DWORD dwDwordValue  = NULL;
    BYTE  byteByteValue = 0;
    MemoryReader.Read<DWORD>( 0x00411474, dwDwordValue );  // Reads a dword from the offset
    MemoryReader.Read<BYTE>(  0x00411474, byteByteValue );   // Reads a byte from the offset
    printf( "Value: %Xrn", dwDwordValue );
    printf( "Value: %X", byteByteValue );

Should probably note that this is for inprocess stuff, so just change *(T*)xxx to ReadProcessMemory, etc.
