Hi Ali,

so you need to create a new file name instead of using the name of an existing file…

What is your problem with this?

I have attached the example code which i got from community.

In the below zip file i have used example vi.

In this example vi the bar code image am writing it using write png. here when i run my vi i want to be create a new png image, for example if i run code for ten times i need 10 png images to be created in a folder.

please help me.

Thanks in advance.

HI shaik,

In this example vi the bar code image am writing it using write png.

I don't see any code writing PNG files…

here when i run my vi i want to be create a new png image, for example if i run code for ten times i need 10 png images to be created in a folder.

You need to use a function like this - available in more recent LabVIEW versions…

But by reading it's help you should be able to implement the same algorithm using the FileFolderExists (or ListFolder) function!
