Hi duaa,

try this function to select a path...

This is another VI you would use to do the actual file-saving, called IMAQ Write File.

Thank you very much for your help

now I can select a path for saving the captured images

but the problem that i can save only 1 image and when it takes another one the first is replaced and deleted, so how can i save all the pictures without any replacements ?

You need to change the filename path on every iteration of  yoru while loop.

how can i do a while loop fot the path name ?

[RavensFan]

Use string functions to build together a filename with a value that changes, such as the value coming from the i node of the loop for the iteration terminal.

Then build that string filename together with the folder path to provide you with a file path that changes each loop iteration.
