Hi Karen,
Actually, I have to write a very simple app that simply needs to receive
datas from a Counter (NI card) and displays it on screen.
Further treatments will be made but in a second project.
NI guys proposed me their "user-friendly" soft (ie. Labview) but at
4.000 Euros just for that... Moreover if I want to create an exe for a
PC I need to acquire a second licence to do so...
My purpose is just to "receive" infos (no need to talk back to the card)
and be able to compile for both Mac and Windows (essentially).
I'd be ready to buy a PC and a Windows RB licence if needed.
Cheers,
Youri

Is there any possibilities to work with National Instruments Cards

I think maybe ...
They have PCI and USB based solutions, they say to be compatible with
Windows and OS X. I found that you can develop solutions on PC using
Visual Basic but no trace of RealBasic.
Is there anyone using these devices with success?
If they have well documented device drivers you might be able to use
them through declares on either platform. We have NIDAQ and GPIB cards
installed, a few years back I created complied Labview Programs to
control the instruments and do the data acquisition on a PC and have
Labview output the intermediate results to textfiles which I then read
and do additional calculations and produce reports from RB (I call teh
RB App from a LabView menu
I glanced at the VB docs briefly for the drivers a few years backs...
and I ***think*** they could be used from RB ... but the waveform
acquisition and processing from the oscilloscope and other LabView
calculations would have been way too much work to port to RB when i had
LabView available, so I did not take it farther and only use RB for
post-processing data management. (IMO doing "Visual programming" in
LabView is a REAL pain ... it's essentially creating wiring diagrams)
NI have products were you can get much of the the LabView functionality
in C++ Libraries which (if you have the expertise - i don't) you could
probably declare to (or wrap to declare or to an RN plug-in) but i
suspect that would be cost prohibitive
