WM_KEYDOWN

[challengerr]

Как отловить все сообщения WM_KEYDOWN посылающиеся в системе?

[Somebody]

SetWindowsHookEx?

делаю так, но код почему-то не действует

подключаемая dll (должен создаваться текстовый файл при срабатывании но он не создается

#include <windows.h>
#include <stdio.h>

#pragma comment(lib, "user32.lib")
#pragma comment(lib, "kernel32.lib")
#pragma comment(lib, "gdi32.lib")

FILE *f;

__declspec(dllexport) LRESULT CALLBACK GetMsgProc(int code, WPARAM wParam, LPARAM lParam)
{
static POINT pnt;
/*
if (code <0)
return CallNextHookEx(0, code, wParam, lParam);
*/

f = fopen("hookproc.txt", "w");

fprintf(f, "hook\n");

fclose(f);

MSG *msg = (MSG* ) lParam;

if (LOWORD(msg->message) == WM_KEYDOWN)
{
GetCursorPos(&pnt);
switch(msg->wParam)
{
case VK_LEFT:
pnt.x -=5;
break;
case VK_RIGHT:
pnt.x +=5;
break;
case VK_UP:
pnt.y -= 5;
break;
case VK_DOWN:
pnt.y +=5;
break;
}
SetCursorPos(pnt.x, pnt.y);
}

return CallNextHookEx(0, code, wParam, lParam);
}
