How to take out a variable out of a while loop?

[DIP_y]

I'm doing a project where I have to take snap shots from a video camera. I've manage to do this part but I can't create a variable file name to save the images. If I can take the variable out of a while loop, in every loop, I can use this value to name the file.

Thank You Guys...

It's a bit hard to guess where you're stuck. Post the code or an screenshot of the relevant piece.

You could write data to a Queue or a Notifier inside the loop to make it available outside the loop.

Can you be more specific?  Do you want to the image to a unique file on each loop iteration?  If so, then just put the write file inside the loop.  You can modify the filename by creating a string constant with a general name like "ImageFile", then convert the loop's iteration terminal, i, into a string, then concatenate the "ImageFile" string and the i string.  You will get a filename like "ImageFile0" on the first loop, "ImageFile1" on the second loop, and so on.  I hope this is what you are looking for.
