Catch IOException?

Ignition
1

I’m trying to export a file using the option exportExcel and it works well most of the times but there are 2 scenarios where is throwing an error

If the file is open or if the user doesnt enter the file extension(xls)

I’m using a try catch but for an unknown reason is not catching the error

Could you let me know what I’m doing wrong?

try:
	filePath = system.dataset.exportExcel(fileName, 1, NewDataSetY)
	if filePath != None:
 		filePath = filePath.replace(' ', '%20')
		filePath = filePath.replace('\\', '/')
		system.net.openURL("file:" + filePath)
except Exception:
	'error'

Thank you

Can you copy the full details of the error message? It’s probably calling out to open the file along a different code path; there may or may not be a way to work around the issue.

Consider using two except blocks, as jython’s standard Exception won’t catch pure java exceptions. Like so:

import java.lang.Exception

try:
    # something something something
except Exception, e:
    # jython exception
except java.lang.Exception, e:
    # java exception

Doesn’t work for the FileNotFoundException thrown here when the file is open.
