MSDN Code erzeugt Fehler

[Pargus]

Hallo Leute,

ich möchte eine DLL zur Kommunikation mit dem USB Port erstellen.
Diese DLL wird in ANSI C geschrieben.
Ich möchte zusätzlich eine Fehlerbehandlung einbauen die mir eine Benachrichtigung schickt sobald ein USB Gerät an oder abgesteckt wurde und habe bei MSDN folgenden Quelltext gefunden (nicht erschrecken sind nur vier Zeilen die einen Fehler verursachen, aber ich Poste trotzdem mal den kompletten Code).

Ich habe meine Haupt-DLL in einer Quelldatei und diese Fehlerbehandlung (unten) hab ich separat als Quelldatei in meinem Projekt gespeichert.

zu den Fehlern:

Fehler entstehen in Zeile 291,292, 314 und 320.
- 291 reinterpret_cast: IntelliSense: Der Bezeichner ""reinterpret_cast"" ist nicht definiert.
- 291 reinterpret_cast: Fehler 3 error C2065: 'reinterpret_cast': nichtdeklarierter Bezeichner
- 291 HINSTANCE: IntelliSense: Der Typname ist nicht zulässig.
- 291 HISTANCE: Fehler 4 error C2275: 'HINSTANCE': Ungültige Verwendung dieses Typs als Ausdruck
- 292 reinterpret_cast: Fehler 5 error C2065: 'reinterpret_cast': nichtdeklarierter Bezeichner
- 292 WndProc: IntelliSense: Der Typname ist nicht zulässig.
- 292 WndProc: Fehler 6 error C2275: 'WNDPROC': Ungültige Verwendung dieses Typs als Ausdruck
- 314 IntelliSense: Unbenannte Prototypparameter sind nicht zulässig, wenn Text vorhanden ist.
- 320 Fehler 7 error C2055: Liste formaler Parameter erwartet, nicht Typenliste

Die Fehler hängen wahrscheinlich alle irgendwo zusammen aber ich blick das nicht so ganz.

Als zusätzliche Info ich bin totaler C-Anfänger. Benötige aber die Hilfe trotzdem. Je ausführlicher desto besser und um Lösungen bin ich auch sehr dankbar.

Vielen Danke für die Hilfe im Voraus.

reinterpret_cast ist C++. Mach einfach den Typ in Klammern davor, Stichwort c-style cast.

ok danke schonmal das behebt die fehler in den Zeilen 291 und 292. Perfekt!

aber was ist mit dem _tWinMain-Fehlern? Wie bekomm ich die noch weg?

also die zwei Fehler:
- 314 IntelliSense: Unbenannte Prototypparameter sind nicht zulässig, wenn Text vorhanden ist.
- 320 Fehler 7 error C2055: Liste formaler Parameter erwartet, nicht Typenliste

[FSK]

Gib dem zweiten, unbenannten Parameter vom Typ HINSCTANCE einen ordentlichen Namen, dann sollte das auch funktionieren.
