Доброго времени суток Ставлю глобальный хук на окно приложения (функция-фильтр в dll). Надо записывать события мыши и клавиатуры для пересылки по сети и воспроизведения на другой машине. Пока работаю с записью. Прога и dll компилятся , но не работают как надо. Помогите найти ошибку, буду очень благодарна. Вот dll: #define _AFXDLL
#define EXPORT extern "C" __declspec(dllexport)
#include "afxwin.h"
#include "stdafx.h"
#include <windows.h>
#include <WinUser.h>
#include <stdio.h>
LPEVENTMSG EventMSG;
HHOOK hook;
__declspec(dllexport) LRESULT CALLBACK JournalRecordProc(int, WPARAM, LPEVENTMSG);
BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
break;
case DLL_PROCESS_DETACH:
break;
default:
return TRUE;
}
return FALSE;
}
__declspec(dllexport) LRESULT CALLBACK JournalRecordProc (int nCode, WPARAM wp, LPEVENTMSG EventMSG)
{
FILE* fp;
fprintf (fp, "nCode = %d\n", nCode);
if (nCode >= 0)
{
fp = fopen ("journal_temp.txt","a");
fprintf(fp, "%d\n", EventMSG->message);
fprintf(fp, "%d\n", EventMSG->paramL);
fprintf(fp, "%d\n", EventMSG->paramH);
fprintf(fp, "%s\n", EventMSG->time);
fprintf(fp, "%s\n", EventMSG->hwnd);
fprintf(fp, "%x\n", EventMSG->hwnd);
fclose (fp);
return CallNextHookEx(hook, nCode, wp, EventMSG);
}
else
{
fclose (fp);
return CallNextHookEx(hook, nCode, wp, EventMSG);
}
} Вот прога: #pragma once
