With LabVIEW you can create just about any application (not limited to measurement applications or target platforms), Dasylab is much ore restricted in its uses.
I see LabVIEW as a general purpose language with strong points in measurent, control, device connectivity and a lot of other things and a weak point in enterprise connectivity.
Dasylab is meant for measurement configuration (programming), LabVIEW programming is NOT configuration (maybe for people using only express VI's).
