This appears whenever errors occur during a data scanning operation. Sometimes it is used to give a list of information (not errors).
It has a toolbar:
From the main program
Copy whole log to the clipboard (not just selected items).
Font to use for print and display.
Print the log.
From data input
Copy the log to the clipboard as CSV style.
Build an OpenXML (Excel) spreadsheet file and open it.
It shows some details about when and why the data log has been produced, followed by a list view of the errors found. The list view contains these columns:
•Serial (the serial number of the questionnaire where the error occurred, or 0 for no serial number)
•Which (if there are duplicate serial numbers, a sequence number within the same serial number)
•Entry (the entry name where the error occurred)
•Extra (more information about where the problem occurred)
•Error (the nature of the problem that occurred)
•System error (the system error message that reported the error)
Some of these columns may be unused for some or all of the errors listed.
Occasionally the number of errors is very large and the program stops recording them. A message then appears above the list view to tell you that not all the errors found are listed in the log.
