怎樣用Delphi得到BIOS數據

procedure TForm1.BiosInfo;
const
Subkey: string = ’’Hardwaredescriptionsystem’’;
var
hkSB: HKEY;
rType: LongInt;
ValueSize, OrigSize: Longint;
ValueBuf: array[0..1000] of char;
procedure ParseValueBuf(const VersionType: string);
var
I, Line: Cardinal;
S: string;
begin
i := 0;
Line := 0;
while ValueBuf[i] <> #0 do
begin
S := StrPas(@ValueBuf[i]); // move the Pchar into a string
Inc(Line);
Memo1.Lines.Append(Format(’’%s Line %d = %s’’,
[VersionType, Line, S])); // add it to a Memo
inc(i, Length(S) + 1);
// to point to next sz, or to #0 if at
end
end;
end;

begin
if RegOpenKeyEx(HKEY_LOCAL_MACHINE, PChar(Subkey), 0,
KEY_READ, hkSB) = ERROR_SUCCESS then
try
OrigSize := sizeof(ValueBuf);
ValueSize := OrigSize;
rType := REG_MULTI_SZ;
if RegQueryValueEx(hkSB, ’’SystemBiosVersion’’, nil, @rType,
@ValueBuf, @ValueSize) = ERROR_SUCCESS then
ParseValueBuf(’’System BIOS Version’’);

ValueSize := OrigSize;
rType := REG_SZ;
if RegQueryValueEx(hkSB, ’’SystemBIOSDate’’, nil, @rType,
@ValueBuf, @ValueSize) = ERROR_SUCCESS then
Memo1.Lines.Append(’’System BIOS Date ’’ + ValueBuf);

ValueSize := OrigSize;
rType := REG_MULTI_SZ;
if RegQueryValueEx(hkSB, ’’VideoBiosVersion’’, nil, @rType,
@ValueBuf, @ValueSize) = ERROR_SUCCESS then
ParseValueBuf(’’Video BIOS Version’’);

ValueSize := OrigSize;
rType := REG_SZ;
if RegQueryValueEx(hkSB, ’’VideoBIOSDate’’, nil, @rType,
@ValueBuf, @ValueSize) = ERROR_SUCCESS then
Memo1.Lines.Append(’’Video BIOS Date ’’ + ValueBuf);
finally
RegCloseKey(hkSB);
end;
end;
