Create Dll from Dev-c++ and reclame

[bub]

Cpp file:

#include "dll.h" 
#include <windows.h> 
#include <stdio.h> 
#include <stdlib.h> 

DLLIMPORT void HelloWorld () 
{ 
    MessageBox (0, "Hello World", "Hi", MB_ICONINFORMATION); 
} 


BOOL APIENTRY DllMain (HINSTANCE hInst     /* Library instance handle. */ , 
                       DWORD reason        /* Reason this function is being called. */ , 
                       LPVOID reserved     /* Not used. */ ) 
{ 
    switch (reason) 
    { 
      case DLL_PROCESS_ATTACH: 
        break; 

      case DLL_PROCESS_DETACH: 
        break; 

      case DLL_THREAD_ATTACH: 
        break; 

      case DLL_THREAD_DETACH: 
        break; 
    } 

    /* Returns TRUE on success, FALSE on failure */ 
    return TRUE; 
}

DLL.h :

#ifndef _DLL_H_ 
#define _DLL_H_ 

#if BUILDING_DLL 
# define DLLIMPORT __declspec (dllexport) 
#else /* Not BUILDING_DLL */ 
# define DLLIMPORT __declspec (dllimport) 
#endif /* Not BUILDING_DLL */ 


DLLIMPORT void HelloWorld (void); 


#endif /* _DLL_H_ */

Script AU3 :

#RequireAdmin
$hDll = DllOpen(@ScriptDir&"\Prog1.dll")
DllCall($hDll,"none:cdecl","HelloWorld")
DllClose($hDll)

Don't work o.O

Help me!!!

If you want to use cdecl, you have to add extern "C" and __cdecl to your function signature

[bub]

example please

Hi,

DLL.cpp

#include "DLL.h"

void DLL_EXPORT HelloWorld()
{
    MessageBox(0, "Hello World", "Hi", MB_OK | MB_ICONINFORMATION);
}

BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
    switch (fdwReason)
    {
        case DLL_PROCESS_ATTACH:
            // attach to process
            // return FALSE to fail DLL load
            break;

        case DLL_PROCESS_DETACH:
            // detach from process
            break;

        case DLL_THREAD_ATTACH:
            // attach to thread
            break;

        case DLL_THREAD_DETACH:
            // detach from thread
            break;
    }
    return TRUE; // succesful
}

DLL.h

#ifndef _DLL_H_
#define _DLL_H_

#include <windows.h>

#ifdef BUILD_DLL
    #define DLL_EXPORT __declspec(dllexport)
#else
    #define DLL_EXPORT __declspec(dllimport)
#endif

extern "C"
{
void DLL_EXPORT HelloWorld();
}

#endif

DllCall("hw.dll", "none:cdecl", "HelloWorld")

Works for me using CodeBlocks/GCC compiler

[Shaggi]

#ifdef BUILD_DLL
    #define DLL_EXPORT extern "C" __declspec(dllexport) __cdecl
#else
    #define DLL_EXPORT __declspec(dllimport)
#endif

returns error!

I removed DLL_EXPORT and is compiled

But... Autoit don't work D:

the DLL is not called =(

[funkey]

Forget Dev-C++ and install Code:Blocks. This is much better than Dev-C++.

[bub]

one day I installed CodeBlocks evil.

and it stopped working ...

has ceased to compiled any project.

always returns this error:

do not need to reinstall, I tried several times.

I gave up.

[bub]

I solved!

I had to fill in the X86 version Autoit -.- "
