QueryServiceConfig

[jShAdEz]

Hi,
I've been using the WIN32API for a while, and still trying to get the
hang of using them in InstallShield. Now I'm trying to use
QueryServiceConfig, which in effect, must take a slump of memory and writes
to it (second argument)

BOOL QueryServiceConfig(
SC_HANDLE hService, // handle to service
LPQUERY_SERVICE_CONFIG lpServiceConfig, // buffer
DWORD cbBufSize, // size of buffer
LPDWORD pcbBytesNeeded // bytes needed
);

I've defined it as follows:

prototype BOOL Advapi32.QueryServiceConfig( NUMBER, POINTER, NUMBER, BYREF
NUMBER );

and used it as follows
typedef QUERY_SERVICE_CONFIG
begin
NUMBER dwServiceType;
NUMBER dwStartType;
NUMBER dwErrorControl;
STRING lpBinaryPathName[1024];
STRING lpLoadOrderGroup[1024];
NUMBER dwTagId;
STRING lpDependencies[1024];
STRING lpServiceStartName[1024];
STRING lpDisplayName[256];
end;
#define nzQUERY_SERVICE_CONFIG 4368

then I pass a pointer to the second argument to this structure, but my
install script keeps crashing ??

Can anyone please help me ? Thanks in advance,
Eric
