No images acquired

[koenrtaad dumont]

hello,

Using Labview 5.1 and Imaq boards PCI 1408 and PCI
1411 with driver version
2.2., I have the following problems:
Under measurement and automatisation the devices
are working fine with both
boards (a colour camera on the 1411 and a spectrograph
on the 1408), I have
a program in labview 5.1 and the advanced IMAQ vision
toolbox to acquire
the data and the images
everything was working well untill I had to reinstall
windows, since then
there are no images acquired under the labview program
and the image windows
just show
a gray field(using the windraw VI) and
the images are not saved to disk. I checked the
interface files and they are the same as in measurements
and automatisation.
But if I deliberatly change the interface file in
the labview program (init
VI) to a wrong file name the result is the same.
So I suppose there is a
problem with the initialisation of the cards. Could
it be a windows 98 problem,
the program was running under windows 95 before?
I tried to run the program
on a 95 computer and the same problems occurred.
By the way, I had to reinstall
window because it was giving general protection errors
during the IMAQ initialisation
during startup.

I would really appreciate some help...

TIA
Koenraad

Now that you have Windows 98, do you still receive a proper image in MAX when you hit Snap? If so, then there must be something in the LabVIEW software that is different. First I recommend updating your NI-IMAQ driver to version 2.51, which is available for free off of our website. Then I recommend running a simple example program in LabVIEW that acquires an image. If nothing else, the example code should give you an error if it isn't working, especially if you're getting a clean image in MAX.
