You might have been using QASetWindowsJournalHook and
QAUnhookWindowsJournalHook. But these functions aren't perfect, but I
suppose they might work for some uses.

Doesn't seem to work. The hook gets set, but the callback never gets called.

Any real sample code would be very helpful.

Here you go. Mostly untested code, without any error handling,
follows:

typedef struct tagEVENTMSG {
UINT message;
UINT paramL;
UINT paramH;
DWORD time;
HWND hwnd;
} EVENTMSG;

typedef HHOOK PQASetWindowsJournalHook(int, LPVOID, EVENTMSG*);
typedef HHOOK PQAUnhookWindowsJournalHook(int);
typedef LRESULT PCallNextHookEx(HHOOK, int, WPARAM, LPARAM);

#define WH_JOURNALRECORD 0

HHOOK g_hook;
EVENTMSG g_eventmsg;
HMODULE hCoreDLL;
PQASetWindowsJournalHook* fnQASetWindowsJournalHook;
PQAUnhookWindowsJournalHook* fnQAUnhookWindowsJournalHook;
PCallNextHookEx* fnCallNextHookEx;

LRESULT CALLBACK QASetWindowsJournalHookProc(
int code,
WPARAM wParam,
LPARAM lParam)
{
if (code < 0)
{
return fnCallNextHookEx(g_hook, code, wParam, lParam);
}
else
{
EVENTMSG * eventmsg = (EVENTMSG*) lParam;
// Do something with eventmsg
return fnCallNextHookEx(g_hook, code, wParam, lParam);
}
}

void BeginHook()
{
hCoreDLL = LoadLibrary(_T("coredll.dll"));
fnQASetWindowsJournalHook = (PQASetWindowsJournalHook*)
GetProcAddress(hCoreDLL, _T("QASetWindowsJournalHook"));
fnQAUnhookWindowsJournalHook = (PQAUnhookWindowsJournalHook*)
GetProcAddress(hCoreDLL, _T("QAUnhookWindowsJournalHook"));
fnCallNextHookEx = (PCallNextHookEx*)
GetProcAddress(hCoreDLL, _T("CallNextHookEx"));

g_hook = fnQASetWindowsJournalHook(WH_JOURNALRECORD,
QASetWindowsJournalHookProc, &g_eventmsg);
}

// If this isn't called, the device will hard-lock when
// the hook procedure is no longer in memory
void EndHook()
{
fnQAUnhookWindowsJournalHook(WH_JOURNALRECORD);
}

Thanks for the code. But just like the code I wrote, this sets the hook, but
the hook callback never gets called. I'm trying to run this on a Windows
Mobile 6 device. Perhaps the undocumented journal hook support is different
on WinMob6.

The one device I tested on was a WM6 device.

As it is, it is undocumented, so it's probably fragile, and IIRC, it
doesn't play well with some things like Transcriber.
