    merge code from 2 projects into one?
    merge code from two files into one?
    link 2 files into one exe/dll?

    Explain better what you need to do.
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    OK,

    I have 2 codes, and i wanna marage them into one and make a dll from them.

    thos are the codes:

    Code 1:

    Code:
    // Include
    #include <windows.h> 
     
    //Globals
    unsigned char NametagsOne[2] = {0x90, 0x90};
    unsigned char NametagsTwo[6] = {0x90, 0x90, 0x90, 0x90, 0x90, 0x90};
    unsigned char NametagsOneOrig[2] = {0x74, 0x25}; // 0042E28E  |. 74 25          |JE SHORT iw3mp.0042E2B5
    unsigned char NametagsTwoOrig[6] = {0x0F, 0x85, 0xCE, 0x00, 0x00, 0x00}; // 0042E26C  |. 0F85 CE000000  |JNZ iw3mp.0042E340
     
    BOOL WINAPI DllMain (HINSTANCE hModule, DWORD dwAttached, LPVOID lpvReserved)
    {
        if (dwAttached == DLL_PROCESS_ATTACH)
        {
       unsigned long Protection;
             VirtualProtect((void*)0x42E28E, 2, PAGE_READWRITE, &Protection);
             memcpy((void*)0x0042E28E, (const void*)NametagsOne, 2);
             VirtualProtect((void*)0x42E28E, 2, Protection, 0);
     
             VirtualProtect((void*)0x42E26C, 6, PAGE_READWRITE, &Protection);
             memcpy((void*)0x0042E26C, (const void*)NametagsTwo, 6);
             VirtualProtect((void*)0x42E26C, 6, Protection, 0);
       return 1; 
        }
     
      return 3142; 
    }

    Code 2:

    Code:
    //Includes 
    #include <windows.h> 
    
    HANDLE CallOfDuty4 = GetCurrentProcess(); 
    BYTE NoRecoil[] = {0x75, 0x12};  // 00457DFF   75 12            JNZ SHORT iw3mp.00457E13
    
    BOOL WINAPI DllMain (HINSTANCE hModule, DWORD dwAttached, LPVOID lpvReserved)
    {
        if (dwAttached == DLL_PROCESS_ATTACH)
        {
             WriteProcessMemory(CallOfDuty4, (void*)0x00457DFF, &NoRecoil, 2, 0);
        }
        
      return 1; 
    }

    And what is the difference between these 2 codes?
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    @lironf18,

    These "codes" are nothing more than game hacks for Call of Duty 4. BTW, are you related to elmutt the other wannabe game hacker? Possibly a distant cousin or something?

    But anyway, here's your compilable DLL. It's essentially garbage and will probably get you punkbusted. I'll quote another member of this board by saying "Is that code? It looks like unreadable hash of mashed tomato juice to me!"


    Code:
    // Filename: myDll.cpp
    // Compile: cl.exe /LD mydll.cpp
    #include <windows.h> 
    
    unsigned char NametagsOne[2] = {0x90, 0x90};
    unsigned char NametagsTwo[6] = {0x90, 0x90, 0x90, 0x90, 0x90, 0x90};
    unsigned char NametagsOneOrig[2] = {0x74, 0x25}; // 0042E28E  |. 74 25          |JE SHORT iw3mp.0042E2B5
    unsigned char NametagsTwoOrig[6] = {0x0F, 0x85, 0xCE, 0x00, 0x00, 0x00}; // 0042E26C  |. 0F85 CE000000  |JNZ iw3mp.0042E340
    
    void beginHacking() 
    { 
        unsigned long Protection;
        HANDLE CallOfDuty4 = GetCurrentProcess(); 
        BYTE NoRecoil[] = {0x75, 0x12};  // 00457DFF   75 12            JNZ SHORT iw3mp.00457E13
        WriteProcessMemory(CallOfDuty4, (void*)0x00457DFF, &NoRecoil, 2, 0);
        VirtualProtect((void*)0x42E28E, 2, PAGE_READWRITE, &Protection);
        memcpy((void*)0x0042E28E, (const void*)NametagsOne, 2);
        VirtualProtect((void*)0x42E28E, 2, Protection, 0);
    
        VirtualProtect((void*)0x42E26C, 6, PAGE_READWRITE, &Protection);
        memcpy((void*)0x0042E26C, (const void*)NametagsTwo, 6);
        VirtualProtect((void*)0x42E26C, 6, Protection, 0);
    } 
    
    
    BOOL WINAPI DllMain( HINSTANCE hInstance, DWORD dwReason, LPVOID _Reserved ) 
    { 
        switch( dwReason ) 
        { 
            case DLL_PROCESS_ATTACH: 
                HINSTANCE  g_hInst = hInstance; 
                beginHacking(); 
    
                return true; 
                break; 
        } 
    
        return true; 
    }

    So if you don't want to "crack" things, what are you doing with code that modifies memory of another process?

    By the way, IMO, "hacking" is the wrong term here, as hacking is really a form of advanced/skilled programming, whilst cracking is the term for "breaking someone elses code", which is clearly what this code is attempting to do.

    this code is public, i didnt steal it or w/e
    did i ask too much to learn on how to compile?
    i know its simple, so please some one just tell me how get it works

    No, but you are attempting to subvert a game into doing things differently - I don't know what the code does in itself, but the general concept of injecting "your own"[1] code into another application is "cracking", and should not be discussed on this forum according to the forum rules that you said you'd obey when you signed up to the forum [even if you just clicked yes without reading them, they still apply to you] - this thread should be locked/deleted.

    [1] Or code you found somewhere on the web, got from a friend, etc.

    This forum exists to help people learn how to program, not to help people cheat (either at homework or video games). Get lost.

    I guess the comparison would be to ask "How do I make heroin?" on a chemistry forum...

    If you were to ask a genuine question on how to achieve something useful [you may think cheating in a game is useful - that's your decision, but in my mind it's not, and I'm the one you are asking to help you].
