Hi,

in der Code-Library gibt es eine Funktion um die Windows-Version zu ermitteln. Ich habe nun Windows XP Media Center Edition 2005 bei meinem Notebook dabei gehabt, aber die Funktion aus der Code-Library sagt mir nun es ist WinXP Prof.
EVEREST Home Edition erkennt aber mein Windows als MCE.

Nun meine frage:
Wie kann man zw. WinXP Prof und WinXP MCE unterscheiden?

Mfg
André

versuche die mal nach deinen wünschen umzubauen

Hi delphicus,

deine Antwort löst mein Problem auch nicht. Ich habe auf MSDN mal nachgesehen dort folgendes gefunden:

Zitat:

An application running outside Media Center can detect whether it is running in Windows XP Media Center Edition by checking for the SM_MEDIACENTER value in a call to the GetSystemMetrics function. For more information, see GetSystemMetrics on the MSDN Web site.

Wenn man jetzt GetSystemMetrics aufruft will die Fkt. ein Integer als parameter. Wie lautet der Wert für SM_MEDIACENTER?

mfg
André

10 Sekunden google ergaben 87.

Hier die Lösung

die Konstante lautet:
SM_MEDIACENTER = 87;

Guten nacht euch allen.

Hi, das funktioniert super. Jedoch hab ich ne Frage. In Windows Vista, werden sind ja unter anderem auch noch andere Editions enhalten. Wenn man das nun unter Vista anwendet, hab ich mir sagen lassen das dort dann Media Center Edition steht, was ich natürlich nicht haben möchte.

http://msdn.microsoft.com/library/de...em_version.asp

Habe ich nach geschaut und bin jedoch nicht fündig geworden, hat jemand ne idee wie man das mit den Versionen herausbekommen kann, bzw Manuell irgendwie dazu schreiben könnte?

Zitat von Jonas:

Habe ich nach geschaut und bin jedoch nicht fündig geworden,

Vista ist noch beta.
(Wenn du es korrekt haben willst, dann kannst du bei > 5.2 'unbekannte Version' schreiben...)

Ja das weiß ich.
Ich hab zu 6.0 Vista geschrieben, was auch wunderbar funktioniert. Nur wird ausgelesen das es eine Media Center Edition ist, obwohl es sich um einer Ultimate Edition handelt.

Zitat von Jonas:

Ich hab zu 6.0 Vista geschrieben, was auch wunderbar funktioniert. Nur wird ausgelesen das es eine Media Center Edition ist, obwohl es sich um einer Ultimate Edition handelt.

Steht denn in der Dokumentation zu Vista, dass SM_MEDIACENTER bedeutet, dass es sich um die MCE handelt?

Zitat von NicoDE:

Steht denn in der Dokumentation zu Vista, dass SM_MEDIACENTER bedeutet, dass es sich um die MCE handelt?

Nee, in der Doku zum Windows SDK für die BETA1 von Vista steht nix drin, wie mann die Versionen von Vista unterscheiden kann. SM_MEDIACENTER bezieht sich nur auf WindowsXP.
