A LabVIEW server application, on client request, take some signals measures from various struments. After, using DataSocket, it sends a response, containing the misured signals, to a client. The client request is send as a cluster transformed into a string using Flatten To String.VI, and server response is send in the same way. The client and the server applications know how read this data using Unflatten From String.VI wiring the right "type" parameter. When the client was running as LabVIEW application there was no problem. The problem is happened when i thinked to transform the client as Visual Basic application using Component Work: now i don't kwow how translate the client request and transla te the server response in the correct format without change the server application.
