Thanks Chris for reply. Workflow is:---
Photo on c:/ as a DNG file
DNG file treated in Lightroom then...
'Exported' from Lightroom as a JPEG file to c:/
This all happens OK --- but after exportation comes the statement
Internal error : Win32 API error 2(" The system cannot find the file specified. ") when calling ShellExecuteExW fromAgWork.ShellExecute
regards
Mike
