ok, been very busy so haven't touched Winbuilder in a while.

Had some time to look at it and have been running into a problem or 2.

When i try to make my LiveXP build i get this error

RegHiveLoad - Failed to load registry hive: [WB-Setup] From file: [%BaseDir%\Target\LiveXP\I386\System32\setupreg.hiv]

The file does exist, so i have no idea what to do

any suggestions?

[pantner]

got it working.

after messing around for 30mins shutting down and running winbuilder, clearing caches and temp folders i restarted my computer and now it works...

The faster way is to start regedit and unmount the hive, which is left from a previous stopped build.

There is "Clean Temporary Files" button on main screen of LiveXP which also unmount redundant hive left from a failure during build.

Thanks, didn't know that!

I did that and it didn't help

It only closes hives which are opened with API - standard names.

When a script mounted a hive with an individual name, the clean function cannot know that.

Thanks panther, and thanks psc.

@psc
I slightly remember there was a utility made by you which closes all hives. Maybe my memory tricks me ! Can you point the right direction.

@psc

works nice

An idea,

is it needed/possible to close only hives from a specific folder, ex: %targetdir%\System32\config\

edit (or file)

[pscEx]

I currently do not know a way, how to get the physical file name of a mounted hive.

Maybe some user can tell me.

@psc


At least normal users wont get into this trouble that cause restart of pc again

"physical file name" i guess you mean the hive name on registry since we can check if hive file(s) mounted by trying to delete or copy


@pantner

now "Clean Temporary Files" button unmounts ALL mounted hives
Update your scripts (specifically script.project)

There is NO known way AFAIK.

Maybe it would be time you could consider this kind of approach:
http://www.boot-land...?showtopic=7681

If we (please read you in this case, as my programming skills are near to 0 ) adopt an independent and "filesystem oriented" approach, it should be possible and relatively easy to log filesystem activities.

Not a priority, of course, but something you should keep in a corner of your mind for when there are no more important things to fix.

I currently do not know a way, how to get the physical file name of a mounted hive.

See registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\hivelist .

It has values like these.
\REGISTRY\MACHINE\SOFTWARE REG_SZ \Device\HarddiskVolume1\Windows\System32\config\SOFTWARE
\REGISTRY\MACHINE\SYSTEM REG_SZ \Device\HarddiskVolume1\Windows\System32\config\SYSTEM

However, I don't known how to determine drive letters of \Device\HarddiskVolumeN.

Good.

The \Device\HarddiskVolumeN is a dynamic value.

It can be found by dosdev:

or dd --list:

I'm rather sure that I now can fullfill lancelot's suggestion.

Don't think there is such a function in the regular registry api. You would need access to the kernel memory structures. May be something in the native api or you may need to write a device driver to access the kernel. Here is information you would need if you had access to the kernel data structures:

Peter

Done

See http://www.boot-land...?...ost&p=81169

@Paraglider: Using native API was not necessary:

Buffer := AllocMem(DefBufferSize);
HivePath := ParamStr(1);
DosDrive := AnsiLeftStr(HivePath, 2);
NTDrive := DOS2NT(DosDrive);
HivePath := AnsiReplaceText(HivePath, DosDrive, NTDrive);
Status := RegOpenKeyEx(HKEY_LOCAL_MACHINE, PAnsiChar('SYSTEM\CurrentControlSet\Control\hivelist'), 0, KEY_READ,regKey);
if Status = ERROR_SUCCESS then
begin
childNum := 0;
repeat
ValueSize := DefValueSize;
BufferSize := DefBufferSize;
Status := RegEnumValue(regKey, childNum, PChar(childName), ValueSize, nil, @KeyType, Buffer, @BufferSize);
if Status = ERROR_SUCCESS then
begin
key := getString(ChildName);
if AnsiStartsText(cHKLM_code, key) then
begin
Value := BinToString(keyType, buffer, BufferSize);
if AnsiStartsText(HivePath, Value) then
begin
Key := AnsiReplaceText(Key, cHKLM_code, '');
RegUnLoadHive(HKEY_LOCAL_MACHINE, key);
Dec(childNum);
end;
end;
end;
Inc(childNum);
until Status <> ERROR_SUCCESS;
RegCloseKey(regKey);
FreeMem(Buffer);
end;

function DOS2NT(const DOS: string): string;
var
buf: string;
begin
SetLength(buf, MAX_PATH);
QueryDosDevice(PAnsiChar(DOS), PAnsiChar(buf), Length(buf));
Result := getString(buf);
end;

@psc

thanks a lot , works nice in my tests, if you agree (if there is no harm danger) i will put it fully to livexp tomorrow.

[pscEx]

I'm sure there is no harm.

Allow me a suggestion:

If possible, put it into 'OnExit' rather than into (or additional to) the project's 'clean' button.
When the build exits, everything should be 'forgotten'

Peter

[Lancelot]

'OnExit' ==> When the build exits, everything should be 'forgotten'

additional to the project's 'clean button => reason ===> sometimes winbuilder halts unexpectadly and user probably would like to start with cleaning first.
and to the very early start of project (hitting blue button with forgeting opened registry hive, maybe manually )
