Hi,
Thank you for the follow up. Perhaps I did not express my need clearly enough, so I made this minimal example; # https://gitlab.com/-/snippets/2155778 > > import pythoncomimport sysimport threadingimport win32com.clientimport > win32com.server.utilfrom win32com.server import localserverdef init_server(): > pythoncom.CoInitialize() > localserver.serve(["{D390AE78-D6A2-47CF-B462-E4F2DC9C70F5}"])class Main: > def __init__(self): self.server = > win32com.client.Dispatch("Minimal.Example") self.server.parent = self > # TypeError: must be real number, not Main self.server.Ping() def > pong(self): return "pong"class ServerAdapter: _reg_clsctx_ = > pythoncom.CLSCTX_LOCAL_SERVER _reg_clsid_ = > "{D390AE78-D6A2-47CF-B462-E4F2DC9C70F5}" _reg_progid_ = "Minimal.Example" > _reg_verprogid_ = "Minimal.Example.1" _reg_class_spec_ = > "MinimalExample.ServerAdapter" _public_methods_ = ["Ping"] > _public_attrs_ = ["parent"] def Ping(self): > print(self.parent.pong()) # How ??if __name__ == '__main__': if > '--register' in sys.argv[1:] or '--unregister' in sys.argv[1:]: import > win32com.server.register > win32com.server.register.UseCommandLine(ServerAdapter) else: > server_thread = threading.Thread(target=init_server) > server_thread.start() app = Main() > > The Ping() method would usually be called from the third-party app, but here it is done locally for the sake of demonstration. >From the server adapter, how can I query values or call methods of another class instance ?
