Simple example for Labview 8.6 Dll to be called by Vb.net Application

[DiopsysP]

First I would like to say that I am not a seasoned programmer for any language.  I have worked with Labview for many years, but never tried to link it with another application.  I have gone through all the pages of the Labview section on this board and have tried most examples, but was not able to get a working application. Some looked very promising, but I just could not figure it out.  I know how to use C++ dlls with Labview, but cannot understand where in Labview I set my "function". In C++, I would have my function exports, but cannot find that in Labview.  If someone has a simple example ( even if it is passing an int and giving that same number back) for a Labview Dll being called by Vb.net I would truly appreciate it.

First, you have to create a project and add the VI(s) to that. Under Build Specifications, right click and select New>Shared Library. You select individual VIs as source files and each one of the VIs you choose is a function. Each control/indicator will be a parameter.dll. Look in the on-line help under 'Shared Libraries>Building'.

There actually is a simple example avilable here: Simple Example Using VB.NET to Call LabVIEW DLLs. Unfortunately, it was written to use LabVIEW 7, and LabVIEW 8.x uses projects, as Dennis mentioned. Attached is the example updated for LabVIEW 8. I only have LabVIEW 8.2 so you may need to recreate the DLL. Just open the project and rebuild the target.

Thanks! This is exactly what I was looking for.  I am sure this will be useful for many more people.
