how to handle error created by cancel file dialog?

[Hummer1]

When I open a file using the Programming>>Files>>Adv File Funcs>>File Dialog I get an error if I hit cancel instead of opening a file or folder as expected.  I understand that there is a boolian (Canceled) available as an output of the File Dialog, but I need help figuring out how to use it to stop the event containing the dialog...and avoiding getting an error message.

The dialog is contained in an event which executes when I hit a "get a file to analyze" button.  If I don't stop the event from running if the Dialog is canceled, some of the other functions through errors related to Not an image file or the like.

Any thoughts?

Thanks.

You basically need to null the error if the dialog is cancelled. For example:

Thanks...will that stop the rest of the event from going forward? ... or do I need to put the file open stuff in one event and the cause an event to handle the successful open of the event seperately rather than trying to handle it all in one event?

Hummer1,

This is interesting.  If you take the existing example and strip everything down except for the dialog it doesn't error out (Interactive Play Sound File.vi).  If you create a new dialog it does.  Even more interesting I copy the working dialog to the non-working dialog and one works the other doesn't...they look to have the same setting:)  Unless a property node has been changed removed and saved?  To check this (OK I hope your still following me) you can disable one or the other and make the error follow the other non-disabled dialog 

Regards,

I don't know what your code looks like, so I can only provide a general answer. Basically, you can enclose the code after dialog in a case structure driven by the "cancelled" output.

What about this?

Just cancel the error based on error number.  It happens that the error number for cancel is 43.

Still doesn't explain why the file I posted never gets an error when you cancel it  -SS

You do get an error. Put an error out indicator on the output. You've probably got automatic error handling turned on. As to why that's not triggering, I can't say - I never use that automatic error handling stuff.
