I use Labview 8.6.1, but this problem is still alive in 2010.
I have tried to create a Source-Code-package (in German Version it is called :Quellcodepaket). By this operation
the NI-CAN-Libray (NITASK.LLB) should also be copied. This operation is impossible on windows operation systems, because in this LLB is integrated the vi called "CAN Get Message ID is Extended?.vi". The name of the vi contains "?" this is not allowed in this context.
Therefore Labview calls an error 1052. (Labview-Filename is not allowed).
Unfortunatly is this not the only standard LLB from NI which has this problem.
This board is for suggesting new ideas on how to improve LabVIEW. But you have an ordinary LabVIEW question. You need to post that in the LabVIEW board.
