Hello Enquan,
 
I could see in the attachement that you have used only one "IMAQ create" function. Use two different IMAQ Create and give image names as Image_1 and Image_2. wire these image out to 2 different grab/snap functions. It will work for sure.

Hello Suhas,
 
Thank you for your response!
 
I have updated my program as your said,but just one image control can show the image,another image control  doesn't work(show nothing).
whatever index(0 or 1) I set when I use IMAQ USB Enumerate Cameras.vi,the image control constantly show the same image.I think just one is
in work,the another camera doesn't  work.

Hello,Suhas
 
I have known why I can't acquire images by using two cameras simultaneously.
Because NI-IMAQ for USB Cameras doesn't support multiple cameras acquisition simultaneously.
Thank you anyway!
