We do this and it works here. Here are two compelling reasons:
- We want to talk to an software package provided by a CCD camera
manufacturer. That
software package uses Microsoft's COM interface, i.e. it exports an object
model. The COM
interface can be called trivially from Visual Basic, but not at all from
IDL.
- It is MUCH easier to write widget interfaces in Visual Basic than in IDL.
Really, David!
- IDL is used to process the spectra we collect and display the results. It
does this in windows
on the Visual Basic screen.
