IMAQ USB - video mode change without popup

Hi,

 

From the following link: http://zone.ni.com/devzone/cda/epd/p/id/5030  regarding the IMAQ USB driver it is suggested that:

 

 

 

-         Configure cameras programmatically (now includes the ability to programmatically select video modes without a popup dialog)

 

 

 

I can find no information nor imagine how this can be done, can anyone please explain?

Hi Martin,

Once you install the USB drivers (in LabVIEW) all you need to do is place the vi "initialize.vi" and select the appropriate video mode in the input. (it can't be done "on the fly")

iI that what you wanted?

Thanx

Thanks for the quick response,

I only have the IMAQ USB Init.vi in my library. Maybe the link on the knowledge base entry is out of date. Where can I download the library with the VI you mentioned contained. Or should the VI come from some where else?

Sorry Martin,
 
Wrong vi on my end (it's been a long day) 
The IMAQ USB Init.vi will do as I said and the ones on the website are both up to date and the only version of the drivers that we have avaliable to us.
 
Thanx

There are only two inputs:

* Error in (standard cluster)

* USB camera name (string)

And I don't think the USB camera name is where I should specify the video mode, or at least is not detailed in the pdf - still confused, please advise.

Hi Martin,
 
Can you post that vi you have.  Mines looks like this... There is only one version of the IMAQ USB driver (it was written and submitted by a customer)

I have opened the llb you attached and great it has the video mode input but now it seems my dll is out of date, I get the error: Call library function node: Function not found in library.

The installer I used (down loaded from the link in my first post) seems to be a different version to me. I have attached the installer and the llb it installed.

Can you please send me the installer you have or the matching DLL?

Thank you,

I got it from here
(same as you)
 
It's the only version of the driver we have ever had.
Try uninstalling yours and reinstalling with the version from the website.

p.s the llb you sent me did have the input "Video mode"

I don't understand what the problem is.
