Most API calls if you pass size needed of 0 it will return the actual size it requires. Then you can call the function again with the correct size.
So if in the first call you pass 0 as the 'cbBufSize' parameter, call the function again and pass the returned value from 'pcbBytesNeeded' as the value for cbBufSize. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: 23 July 2004 1:44 PM To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] Services Has anyone used QueryServiceConfig ? I cant get it working. When I pass the structure Service_Config it returns an error saying it needs 226 bytes (whereas the size of the Service_Config is 36 bytes).Regards Rohit ==================================================== ================== CFL - Computer Fanatics Ltd. 21 Barry's Point Road, AKL, New Zealand PH (649) 489-2280 FX (649) 489-2290 email [EMAIL PROTECTED] or [EMAIL PROTECTED] ==================================================== ================== _______________________________________________ Delphi mailing list [EMAIL PROTECTED] http://ns3.123.co.nz/mailman/listinfo/delphi _______________________________________________ Delphi mailing list [EMAIL PROTECTED] http://ns3.123.co.nz/mailman/listinfo/delphi
