We have a flat panel connected with a NI 1424 framegrabber. The framegrabber is in a computer running on Windows 7 64-bit. In the past we used the imgGrab function of the NI-IMAQ functions.
Recently, to improve the speed of data acquisition, we started to use the imgSnap function. (http://zone.ni.com/reference/en-XX/help/370161G-01
Did anyone experience the same problem and has anybody a solution?

Which drivers are you using?
Can you upload a MAX Report (http://digital.ni.com/public.nsf/allkb/271F252B4EF
Does the function return a 0 ("succes") after using it?

The MAX report is in attachment. When doing imgsnap, we check if the function returns an errorcode, but always a 0 is returned.
FYI: We are using the Visual Studio 2010 C++ compiler to compile our software.
Thanks for the help,

I think I have found a probable cause for the issues you encounter.
According to these KB's the versions of NI-IMAQ and NI-IMAQdx you're using do not officially support Winddows 7 (32 or 64-bit):
Can you download a newer version of these drivers that officially supports Windows 7?

Can you provide me with the MAX Reports of both pc's (working and non-working) and also with the code used on both pc's?
This will allow me to eliminate certain things.
Are you using exactly the same card (by moving it from one pc to the other) in both pc's or 2 seperate cards of the same type?

In attachment, you will find the MAX report for the Windows Vista 32-bit system. The configuration for the Windows 7 64-bit system, you will find in one of the previous posts. We used the same NI card and detector in the both set-ups. We just swapped them from one computer to the other.

The last MAX Report didn't really make me much wiser.
If you compare it to the previous one, then you can see that there is no card inserted or camera connected to it.
Therefor I cannot derive any of the settings/configurations that were done (at camera or framegrabber level) in MAX for the working Vista system.
Is there a way to provide me with this information?

I had a look at your MAX Reports and I saw the following differences:
