It seems to me that you are planning to make calls to your Altera Device Programming software from labview and get the data from it.
First to get started on it, you need to know how ActiveX and VIs in labview work. I'd recommend looking at LabVIEW shipped ActiveX examples just to get idea of how it all work.
One of the crucial parts to be a good ActiveX coder is to understand the ActiveX object model. In your case you need to know the ActiveX object model for Altera. Usually manufactuere provides some documentation and/or examples.
One thing that i'd highly recommend is buying some good labview book and/or taking "LabVIEW Advance Course" that NI offers.
Hope this would help
