From string to Jpeg

[Carmine_]

Hello to all.
I'm trying to capture an image from a camera connected to the PC with arduino.
I can get a string with the code of labview image jpeg (from FFD8 to FFD9) but I can't view it in any way.
I have tried all.

http://forums.ni.com/t5/Machine-Vision/Convert-JPEG-image-in-memory-to-Imaq-Image/td-p/851074 (the program not displays the image)

but can view the image.
I hope you can help me.
thanks.

I use Labview 2010 with NI-IMAQ.

hi Carmine,

in order to understand your problem, i want ask you a couple of things.

1) You have install the LabView interface for Arduino Toolkit?

2) From first link that you attached me, you can try the second dll?

3) From second which are the results?

Thanks

3)but like a first when run the program labview crash...

Try saving the striing as a jpeg file, then reading the file.  If you don't get an image, there is something wrong with your string.  The string should be exactly equal to the contents of a jpeg file.
