Long story, long:
I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure). LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file.

I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure. When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure, populate the structure from the data file, then call the method to transfer the data back to the website.

Long story, short: How do you recommend I transfer (copy) an instance of a structure from one .NET program to a VB.NET program?

Ideas considered: sockets, temp file, xml file, config file, web services, CSV, some type of serialization, shared memory
