Hi :graduated:

im trying to make a Dll in C++ , and i only know the basics in C++ , so its kind of hard

the dll im trying to make is taken from a program source code i downloaded , here it is

#include "resource.h"
#include "windows.h"
#include "windowsx.h"
#define IDT_TIMER1 10001
#define IDT_TIMER2 10002
#define IDT_TIMER3 10003
#define IDT_TIMER4 10004
#define IDT_TIMER5 10005
#define IDT_TIMER6 10006
#define IDT_TIMER7 10007
#define IDT_TIMER8 10008
#define IDT_TIMER9 10009
#define IDT_TIMER10 10010

}

i want to make a dll with SendKey function so heres my source code

SendFunc.cpp

#include "stdafx.h"
#include <windows.h>
 
extern "C" __declspec(dllexport) int __cdecl SendKey(WPARAM VK);
DWORD _PMA = (DWORD)GetProcAddress(LoadLibraryA("user32.dll"), "PostMessageA") + 5;
 
__declspec(naked) BOOL WINAPI _PostMessageA(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    __asm
    {
        mov edi, edi
        push   ebp
        mov ebp, esp
        jmp dword ptr ds:[_PMA]
    }
}
 
__declspec(dllexport) int __cdecl SendKey(WPARAM VK)
{
    HWND hWnd = FindWindowA("Notepad", "Untitled - Notepad");
    HWND hWnd2 = FindWindowExA(hWnd, 0, "Edit", 0);
    _PostMessageA(hWnd2, WM_KEYDOWN, VK, 0);
    return 0;
}

DllTest2.def

LIBRARY   DllTest2
EXPORTS  
    SendKey   @1

and i want to call it using AutoIT

$Test = DllCall("DllTest2.dll","int","SendKey","int","0x31")
If @error Then MsgBox(0,"",@error)

but AutoIT crashs everytime =\

lol who uses inline asm code for winapi calls, are you patching something? If not, please change this:

__declspec(dllexport) int __cdecl SendKey(WPARAM VK)
{
    HWND hWnd = FindWindowA("Notepad", "Untitled - Notepad");
    HWND hWnd2 = FindWindowExA(hWnd, 0, "Edit", 0);
    _PostMessageA(hWnd2, WM_KEYDOWN, VK, 0);
    return 0;
}
To this:
__declspec(dllexport) int __cdecl SendKey(WPARAM VK)
{
    HWND hWnd = FindWindowA("Notepad", "Untitled - Notepad");
    HWND hWnd2 = FindWindowExA(hWnd, 0, "Edit", 0);
    PostMessageA(hWnd2, WM_KEYDOWN, VK, 0);
    return 0;
}
I do not understand why you want to write a dll for this, you can do it directly in autoit? Also, your exported function is declared as _cdecl, so in return type you need to write "int:cdecl".

Also, int != wparam, this breaks on x64 compatibily, and also you're passing a string as an argument for an integer...

Lastly, are you sure you are running this in x86 version of autoit?

lol who uses inline asm code for winapi calls, are you patching something? If not, please change this:

__declspec(dllexport) int __cdecl SendKey(WPARAM VK)
{
    HWND hWnd = FindWindowA("Notepad", "Untitled - Notepad");
    HWND hWnd2 = FindWindowExA(hWnd, 0, "Edit", 0);
    _PostMessageA(hWnd2, WM_KEYDOWN, VK, 0);
    return 0;
}
To this:
__declspec(dllexport) int __cdecl SendKey(WPARAM VK)
{
    HWND hWnd = FindWindowA("Notepad", "Untitled - Notepad");
    HWND hWnd2 = FindWindowExA(hWnd, 0, "Edit", 0);
    PostMessageA(hWnd2, WM_KEYDOWN, VK, 0);
    return 0;
}
I do not understand why you want to write a dll for this, you can do it directly in autoit? Also, your exported function is declared as _cdecl, so in return type you need to write "int:cdecl".

im not really good in c++ ( im sure you can tell )

but i want to send keys to a program that gameguard is protecting , gg blocks blocks autoit send func ( also mousemove and mouseclick )

according to this , int = wparam , and about the string passing , i realized that but forgot to edit it

and maybe im having a problem reading the code you told me to replace , because both of them are identical , and yes its x86
