Hello Mr_ask,

It appears that you're using LabVIEW 2012, so you probably want to use the IMAQ Write File 2 VI available in Vision Utilities>>Files rather than the deprecated IMAQ WriteFile.  I believe that the old IMAQ WriteFile VI doesn't support all of the image types currently allowed by IMAQ, so the issue might be that you're attempting to save in an unsupported format, although that's largely a guess.

Are you seeing any errors when you attempt to save the image?  If so, what are they?  Screen captures of the error number and message would be very helpful.

Regards,

thank you for an immediate reply mr outlaw.

fortunately i dont have any errors in my vi.
My vi..

view the real time image and it captures too. but my only problem is to save the image that i have captured already.

my only problem is that..

the push button for SAVE is not executed because it is outside the while loop.

i attatched the print screen of my VI. i encircled the block diagram that i know there is the problem.

Thanks again mr outlaw!

Then move that code inside the loop!

[Mr_ask]

yep i tried to move it to the loop. and the push button works. but still the captured message cannot be saved.

Attach your latest VI.
