KEYBOARDHOOK fängt nicht alle ereignisse der tastatur ab

[chickonspeed]

hoi,

ich wollte mal nen programm machen das mir *alle* tastatur eingaben mitloggt.
dazu hab ich aus dem faq-bereich der winapi die dll für das keyboardhooking verwendet.

soweit so gut. inerhalt meiner applikation funktioniert das ganze auch ganz gut. allerdings bekomme ich es nicht mit wenn ich außerhalt der applikation etwas eintippe (obwohl das eigentlich mit der dll funktionieren sollte wenn ich es richtig verstanden habe). hierzu mal ein bischen code (statt dem code für die dll hier der link -> http://www.c-plusplus.net/forum/viewtopic.php?t=39383)

Moin,

mit der Funktion ProcSetup übergibst du den WindowHandle deines aktuellen Fensters, deshalb werden auch nur die Tastatureingaben dieses Fensters aus gewertet. Da ich jetzt nicht genau weis wie die Libiray arbeitet gege ich mal davon aus, dass sie auf den normalen API Funktionen aufsetzt. Deshalb probiere es mal mit den Handelwert NULL, dann sollten alle Tastatur eingaben protokolliert werden, bzw. mit den Handele des Fensters dessen Tastatur eingaben du aufzeichnen möchtest.
