Re: Problem beim auslesen der Festplatten Seriennummer
 
Wie wärs denn damit ?
Delphi-Quellcode:
_STORAGE_PROPERTY_QUERY=record
PropertyId:STORAGE_PROPERTY_ID;
QueryType:STORAGE_QUERY_TYPE;
AdditionalParameters:Array[0..0] of UCHAR;
end;
STORAGE_PROPERTY_QUERY=_STORAGE_PROPERTY_QUERY;
PSTORAGE_PROPERTY_QUERY=^STORAGE_PROPERTY_QUERY;

Re: Problem beim auslesen der Festplatten Seriennummer
 
hmmm

Undefinierter Bezeichner 'STORAGE_PROPERTY_ID'
Undefinierter Bezeichner 'STORAGE_QUERY_TYPE'

was hast du da noch eingebunden ?

Ist das in der winioctl.h drin ?
Die hatte er bei c++ eingebunden, aber ich finde das equivalent in Delphi nicht :/

Re: Problem beim auslesen der Festplatten Seriennummer
 
hmmm *kopfqualm* :wiejetzt:

So ganz verstehe ich nicht was der da treibt :(
Ich habe mal die Funktion mit deinen Änderungen versucht in Delphi zu übertragen.

Im Moment erstmal bis zum Aufruf von DeviceIoControl
Aber leider liefert der immer false.
Steigt vielleicht jemand mehr durch den c++ code von oben durch und sieht was ich falsch mache?

Re: Problem beim auslesen der Festplatten Seriennummer
 
Hallo,

gibt es denn keinen C++ Profi hier der sich des funktionierenden C++ codes mal annehmen könnte und ihn nach Delphi zu portieren? :love:
Ich komme damit nicht wirklich weiter :wiejetzt:

Hast du hier eine Lösung gefunden ? Würde das auch sehr gerne nutzen...

Re: Problem beim auslesen der Festplatten Seriennummer
 
Dazu sollte wohl nur mal erwähnt werden, daß man sich an die windows-/systemspezifischen Typen, Ausrichtungen, und Größen halten sollte, wenn man schon versucht derartiges zu machen.

hier nun eine korrekte Typendefinition (so wie sie von windows verwendet wird):
Delphi-Quellcode:
STORAGE_QUERY_TYPE = cardinal{PropertyStandardQuery = 0, PropertyExistsQuery = 1, PropertyMaskQuery = 2,
  PropertyQueryMaxDefined = 3};
STORAGE_PROPERTY_ID = cardinal{StorageDeviceProperty = 0, StorageAdapterProperty = 1};
STORAGE_PROPERTY_QUERY = packed record
  PropertyId: STORAGE_PROPERTY_ID;
  QueryType: STORAGE_QUERY_TYPE;
  AdditionalParameters: array[0..3] of UCHAR;
end;
Und hier noch eine zwar nicht ganz korrekte, aber dennoch Funtionierende:
In C++ sind STORAGE_QUERY_TYPE und STORAGE_PROPERTY_ID 4 Byte groß und nicht 1 Byte (so wie in Delphi).
Delphi-Quellcode:
STORAGE_QUERY_TYPE = (PropertyStandardQuery, PropertyExistsQuery, PropertyMaskQuery,
  PropertyQueryMaxDefined);
STORAGE_PROPERTY_ID = (StorageDeviceProperty, StorageAdapterProperty);
STORAGE_PROPERTY_QUERY = packed record
  PropertyId: STORAGE_PROPERTY_ID;
  _fill1: array[0..2] of byte;
  QueryType: STORAGE_QUERY_TYPE;
  _fill2: array[0..2] of byte;
  AdditionalParameters: array[0..3] of UCHAR;
end;

Delphi-Quellcode:
function GetIdeDiskSerialNumber: String;
  function CTL_CODE(DeviceType, Function_, Method, Access: cardinal): cardinal;
    begin result := (DeviceType shl 16) or (Access shl 14) or (Function_ shl 2) or Method; end;

  end;

ach ja, für'n Anfang hätte man och ma versuchen können, sich die Fehlermeldung zu besorgen!
Delphi-Quellcode:
SysErrorMessage(GetLastError);
und bei der gegebenen Fehlermeldung ist wohl das Erste und Einfachste eine Vergößerung/Anpassung der Größer der Ein-/Ausgabepuffer. :zwinker:

Hallo,

ich schreibe gerade für uns ein Inventory Tool welches Hard- und Software der Geräte erfasst.

Hallo,

habe den Code mal eben in eine Unit kopiert. Auf den Notebook mit IDE funktioniert das. Auf meiner Wks mit Ultra320 kommt nur ein Leerstring zurück.

Gruß

Auf http://artsoft.nm.ru/ findest du die neuste Version von HDDInfo. Bei mir funktioniert diese Komponente hervorragend!
