 Posted: Wed Oct 01, 2008 12:42 pm Post subject: [C++] Simple help question with PostMessageA(Updated) |
 |
|
I managed to fix my error but however this isn't working as it should.
When im ingame and run the code it starts to spam "A" but my character doesn't attack(My attack key is "A")
(The game is MapleStory btw.)
my code looks like this now:
Code:
| Code: | #include "windows.h"
#include <tchar.h>
#include <iostream>
using namespace std;
LRESULT InjectMessage(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {
WNDPROC WndProc;
LRESULT lRET = 0;
WndProc = (WNDPROC)GetWindowLong(hWnd, GWL_WNDPROC);
if (WndProc != NULL)
lRET = CallWindowProc(WndProc, hWnd, uMsg, wParam, lParam);
return lRET;
}
int main() {
while (true) {
HWND hWndE = FindWindow(_T("MapleStoryClass"),0);
PostMessage(hWndE, WM_CHAR, 'A', 0);
Sleep(1);
}
} |

use L"MapleStoryClass" instead and btw the 2nd parameter is the window name not the class name so switch them
another thing you can use is
and then you can use it like this
| Code: |
FindWindow(_T("MapleStoryClass"),0);

| Keep in mind that there are 2 versions of most windows API, the ones that end in W are for unicode char and the ones ending in A are ansi encoded char. If you look in windows.h you see #define FindWindow FindWindowW.

of course it won't attack cuz you send wm_char and it sends the virtual key of 'A' and doesn't actually press on A
to press on a key use WM_KEYDOWN

Ok i changed this:
| Code: | | PostMessage(hWndE, WM_CHAR, 'A', 0); |
to this which presses 0 (I changed my attack to "0") but still it doesen't attack 
| Code: | | PostMessage(hWndE, WM_KEYDOWN, 0x71, 0); |

cuz you need to bypass the hook of user32 API's or however it called
why aren't you using InjectMessage that you implemented before
or you can bypass it yourself by jumping 5 bytes over the hook

Actually i have the bypass. Here is the full code:
(and im not yet very experienced with C++ so im making little mistakes of course)
| Code: | #include "windows.h"
#include <tchar.h>
#include <iostream>
using namespace std;
DWORD _PMA = NULL;
LRESULT InjectMessage(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {
WNDPROC WndProc;
LRESULT lRET = 0;
WndProc = (WNDPROC)GetWindowLong(hWnd, GWL_WNDPROC);
if (WndProc != NULL)
lRET = CallWindowProc(WndProc, hWnd, uMsg, wParam, lParam);
return lRET;
}
__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]
}
}
int main() {
if(HWND hWndE = FindWindow(_T("MapleStoryClass"),0))
{
cout << "MapleStory window found!", cout << endl;
}
while (true) {
if(HWND hWndE = FindWindow(_T("MapleStoryClass"),0))
{
// HWND hWndE = FindWindow(_T("MapleStoryClass"),0);
PostMessage(hWndE, WM_KEYDOWN, 0x30, 1);
Sleep(10);
PostMessage(hWndE, WM_KEYUP, 0x30, 1);
Sleep(10);
}
else
{
cout << "MapleStory window not found!", cout << endl;
Sleep(5000);
}
}
} |

still i don't see u use the bypassed API,
it's good that you bypassed the hook but u don't use it
u still use PostMessage instead of _PostMessage, plus your _PMA variable contains a NULL value, to get the the API Address use this
| Code: |
_PMA = GetProcAddress(LoadLibraryA("User32.Dll"),"PostMessageA") + 5;
|
then it should work fine
edit: to send the key perfectly to the game you need to use also MapVirtualKey plus shifting left 16 bits of the key
| Code: |
_PostMessage(hWnd,WM_KEYDOWN,0x71,(MapVirtualKey(0x71,0)) << 16);
|

you're welcome,
it's not that i pro it's just was your mistakes that i fixed
u implemented a function but you used another one so agree with me that it doesn't make any sens
and you wished to jump over the hook to _PMA value, but the thing is that u left it NULL and it can't jump to 0 address, there's no such thing
anyway keep practicing,have a nice day =]
