 Posted: Wed Nov 18, 2009 8:16 pm Post subject: [Help] SetWindowsHookEx Dll Injection |
 |
|
Its not working, i'm testing it on notepad. What I do is do a global dll injection with my first temporary dll, this dll will go through all the hwnds through the WH_CBT hook and try to find my targets window title, and then if I found it I inject my second real dll and unhook my hook.
This is my console:
| Code: |
#include <windows.h>
#include <iostream>
using namespace std;
void main()
{
HMODULE hDll = LoadLibraryA("C:\\...\\...\\Documents\\Visual Studio 2008\\Projects\\SetWindowsHookEx\\Debug\\System.dll");
HOOKPROC GetCBT = (HOOKPROC) GetProcAddress(hDll, "CBTProc");
HHOOK Hook = SetWindowsHookEx(WH_CBT, GetCBT, hDll, 0);
system("PAUSE");
}
|
This is my Dll:
| Code: |
#include <windows.h>
#include <iostream>
using namespace std;
BOOL WINAPI DllMain(HINSTANCE hinstDll, DWORD fdwReason, LPVOID lpReserved)
{
return TRUE;
}
LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if (nCode == HCBT_ACTIVATE)
{
HWND hWnd = (HWND) wParam;
char Title[500] = {0};
GetWindowTextA(hWnd, (LPSTR) Title, MAX_PATH);
if ((LPSTR) Title == "Untitled - Notepad")
{
LoadLibraryA("MyDll");
UnhookWindowsHookEx(0);
}
}
return CallNextHookEx(0, nCode, wParam, lParam);
}
|
Please help, this wont work, I keep clicking on Notepad when the dll is injected to try and get my WH_CBT callback to work.

Try to just put a MessageBox in the CBTProc after nCode==HCBT_ACTIVATE to see if the message is even received.
Also:
When you want to unload the temporary dll, first unhook the WindowsHook and then use FreeLibraryAndExitThread() to unload and quit.

Found the problem, make sure nCode is:
| Code: | if (nCode == HCBT_ACTIVATE || HCBT_SYSCOMMAND || HCBT_DESTROYWND)
{
}
