the next registry key is marked as shared in my installation/upgrade(APP1):  
"HKEY_LOCAL_MACHINE\SOFTWARE\CompanyName"

after i install app1 the registry exist.


APP2 also writes other registrykeys in the same keyPath:
"HKEY_LOCAL_MACHINE\SOFTWARE\CompanyName"

well when i have both applications installed and i de-install app1 it removes all registry under :
HKEY_LOCAL_MACHINE\SOFTWARE\Oce.
so APP2 doesnt work any more.

is this an IS bug i expect APP1 to not remove this key , because i marked it as shared? and remove only the keys that were made by APP1.

Or do i have to do something else next to marking the key as shared?

hope someone can help me.

greetings fouad

thx again tacobael

i now use RegDBCreateKeyEx to craate the company registry key. but now i encounter other problems.

i disable logging when i set this key, but i need to have this key removed if there is no other applications using this key.

how can i check if there are other keys beneath the company key, without knowing the values of there keys.

i thinks this is impossible. so i will have to accept that they key will always remain behind

That same question has popped in my head before, but since I haven't had a need to do it, I haven't looked into it.  Therefore, as far as I know, that's not possible, but someone please correct me if I'm wrong.

Hi,

some weeks ago, I was in a need of such a solution.

Here is it :

Code Sample

//arguments: //  nHive = hive key, e.g. HKEY_LOCAL_MACHINE //  szRKey = subkey beneath the hive key, e.g. "Software//Company//Product_x" // //returns: 0 if no subkey (szRKey was deleted) //         -1 is there were subkeys or entries function RemoveSubKeyIfEmpty(nHive, szRKey)  NUMBER nRet;  LIST   listNames, listKeys;   begin  RegDBSetDefaultRoot(nHive);  listNames = ListCreate(STRINGLIST);  listKeys  = ListCreate(STRINGLIST);  RegDBQueryKey(szRKey, REGDB_NAMES, listNames);  RegDBQueryKey(szRKey, REGDB_KEYS, listKeys);  if ( (ListCount(listNames) <= 0) && (ListCount(listKeys) <= 0) ) then //is empty    RegDBDeleteKey(szRKey);    nRet = 0;  else    nRet = -1;    endif;    ListDestroy(listNames);  ListDestroy(listKeys);    return nRet;   end;

Thanks Eberhard, i was searching for such a function (RegDBQueryKey).
