Cancel write to jpeg.vi problem

[JDlabview]

Hello,

I've got a problem with write to jpeg VI : when I choose to cancel the dialog box, my program is in trouble, as if I changed the state of my machine state... or if I re-initialized it.

So my question is : how can I manage it ? I have no access to write to jpeg block diagram, as it is password protected.

here is a screen of the sub vi. thanks

Do not use the implicit way to display the File Dialog but do it explicitly (File Dialog.vi in File IO palette >> Advanced).

Capture the error of the dialog if canceled (should be Code 43) and react properly on this in your application.

hope this helps,

Norbert

You can connect the error to the case structure and do what you want in the error case. You can also try using file dialog vi from file functions

Thanks to both of you, I post the solution if someone needs it
