First off: I would NOT use the Registry ever for my new applications... Instead I would use conf files in ini file format so I can read/write them using the TIniFile or TMemIniFile classes. But my task now is to port a Windows service program which is controlling the scheduling of external equipment operations. It is a Windows service and thus non-gui but it implements a socket communications channel whereby existing Windows (Delphi) applications can control it by writing config data and look for results etc. We can no longer use the service application on Windows going forward because of Microsoft changes to drivers we rely on etc. So the idea is to convert the service application to FPC/Lazarus and then port it over to Linux. So, being a service the server uses the Registry for all of its config and task data on Windows and it would be simpler to port if I can continue using that part of the system. At first look TRegistry seems to handle this. But there is a problem: On Windows HKLM is a *global* hive and by what I hear here the TRegistry implementation for Linux uses xml files instead and that is no problem, provided that there is one only such file in use. But if they are application specific then it will not work. We use different applications to manage the server via the Registry and this would not work then. For example we have a local server configuration utility apart from the TCP/IP socket connection and if I understand it right this application would operate on a *different* xml file altogether so whatever changes it makes to the "registry" will not be available to the service application... If this is so I need to reconsider the use of TRegistry and dig down into changing to conf files (which can be global)... Much more code to convert in that case. -- Bo Berglund Developer in Sweden -- _______________________________________________ lazarus mailing list [email protected] https://lists.lazarus-ide.org/listinfo/lazarus
