You probably don't need the extra complication of IPC, sockets, COM, or OLE automation. Instead of creating a D7 app, build a D7 DLL which exports the function(s) you need. Import the DLL function(s) to your Lazarus app and call them directly. -- _______________________________________________ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
