    Just to clear some things up and to show I look like an idea...

    My host file probeblem was caused by...

    1. Having all 3 of the files (dll.h, dll.cpp, mainfile.cpp) in the same project file.

    2. If I didnt' do 1. then I still have all 3 files open at the same time.



    Oh and YES it DID WORK!!!!



    Finally!!!!!!!!!!!

    Ok sorry btu I got anoutehr probelem...

    In this code...

    This is the mainfile.cpp...

    Code:
    #include <windows.h>
    #include <iostream>
    
    int main()
    {
        // Function Pointer
        void(*TextFunc)();
        
        // Load DLL 
        HMODULE hMod = LoadLibrary("wordset1.dll");
    
        // Assign the function pointer to the 
        // address of the function in the dll
        TextFunc = (void(*)())GetProcAddress(hMod, "test");
        
        // If it found it
        if(TextFunc) TextFunc();
            
        std::cin.get();
        return 0;    
        
    }
    In the part...

    Code:
    void(*TextFunc)();
    I don't want a just text. I want it so I can have variables declared and everything else.

    How do I do that?

    Here you go:

    void somefn();
    void (*psomefn)() = somefn;

    int somefn();
    int (*psomefn)() = somefn;

    int somefn(char*, int);
    int(*psomefn)(char*, int) = somefn;

    Yeah, a function pointer will work about the same way as a normal function (You can pass arguments through them).

    With out creating an object, (class or struct) Im not sure if you could point to variables in that same way. But you can definately use functions to return certain values like bithub stated.
