Hi Kals,

to use dlls in your code use "Call Library Function Node".

Hi Kals,
I responded to your post about camera-specific DLLs in the separate thread you made here.

Quoted from that linked thread:

Hi Kals,
If you use a camera-specific DLL to work with your camera, you can use the Call Library Function Node VI to call and interact with the DLL and you will not need to use the IMAQ USB Session VIs.

If your camera-specific DLL returns a numeric array to represent your image, you can use the IMAQ ArrayToImage VI to convert it into a form that LabVIEW can handle if you need to use it for other vision VIs. You would first need to use IMAQ Create to create a destination for that image to be placed, and wire its "New Image" out terminal as the "Image" input terminal to the IMAQ ArrayToImage VI.
