I have recently come to know that IDL scipt can be compiled from LabView and I believe that it's a new added features. However, I do not have any idea of how to do it.
IDL script was actually developed by one of our Alliance members and
they have developed a LabVIEW toolkit for it as well. You can find
information about it on the following website:

You might be able to make IDL calls using ActiveX from LabVIEW directly
but this can get tricky. Here are some tutorials on how to do ActiveX
calls from LabVIEW in case you need some help with that:
