To All My team and I have been working on a client-server based application. The server is a Labview based and is serving up remote panels via an Explorer window. The client machine has the Labview runtime engine (LVRT) on it. At a certain point, we need to execute a VI within a complied Labview EXE file but run it on the client machine. We have been able to do it but the solution was not what we expected. We expected to be able to open an application reference to the VI Server on the Client machine (with the LVRT engine) and instruct the VI Server to execute the VI. We found that we could not do this unless there was already a VI running on the client machine. The VI that was running had to

Todd, My IT guy tells me that we can receive such a file. If you can zip it up and send it after hours it would be better. Please send directly to jwest@summitekinstruments.com Jim

Todd, I'm not sure that whether I can receive such a large file. Is there a way to break it up into a few pieces? I have certainly receive emails up to 10MB in size. Our IT guy is out to lunch at this instant; there may be a way to upload to our server. Can you email me directly so we can discuss the details? Jwest@summitekinstruments.com Jim

I was investigating LabVIEW and Diadem and found an app note that uses a set of example programs they call

I believe that the next evolutionary step for Labview will come from better design techniques. The programming language has all of the elements necessary. Labview programmers need to embrace Object oriented design techniques. (OO) In mainstream software projects, OO design has proven to be a flexible method to accomodate requirement changes and provides a organizational dividing line for members of the development teams. Labview developers have not needed these design techniques since they typically are working on small applications. For many Labview developers, functional design techniques are comfortable and arguably appropriate. Functional design techniques began to fail when they were applied to large applications which require more than a few programmers. Unfortunately, OO development requires a certain level of domain expertise; that the average Labview programmer may not have or need. The GOOP toolkit is a step in the right direction. The toolkit provides some building blocks for OO design. I encourage you to study this toolkit and think about how would you describe your software in terms of objects and their lifecycles. The books I was trained on are vintage now. Newer books may be more appropriate. "Object-Oriented Systems Analysis..." and "Object Lifecycles..." by Shlaer and Mellor. Jim West
