Exercise 2 - Error Checking

Chronolator automatically checks for errors every time an Internal Chronology is closed. It does not save the details about any errors it finds unless you save the document, so you can also check for them at any time by pressing the Check Tables button on the toolbar.

Chronolator checks the document for errors.

Step	Action	What to expect and other comments
1	Read Chronolator Toolbars and About the Exercises if you have not already done so.
2	Open SampleTableWithErrors.
3	Close SampleTableWithErrors.	Chronolator checks the document for errors. When the check completes, Message 3005 is displayed, asking you to correct the errors before returning the document. Internal Chronologies are checked every time they are closed, helping to ensure that administrators receive error-free documents.
4	Press OK.	The document closes. You would press Cancel if you wanted to keep the document open and correct the errors.
5	Open SampleTableWithErrors.
6	Press Check Tables.	Chronolator checks the document for errors. When the check completes, Message 3000 is displayed, asking you to correct the errors before returning the document. Chronolator has been designed so that there is little need to read the extensive documentation. Its messages usually have enough information in them for you to know what to do next.
7	Press OK.	Message 3001 is displayed. Chronolator can correct rows which have the wrong number of columns, but it cannot be sure that it has placed information under the correct heading.
8	Press OK.	The document is displayed with errors highlighted. A flag like this ⌧ is shown to the left of each error:
9	Use the navigation buttons on the toolbar to go from one error to the next:	The cursor goes to the requested error. In this short sample document there is not much advantage in doing this over simply looking for highlights, but if there are just a few errors in a 300-page document, the navigation buttons become very useful.
10	Press the Go To List navigation button:	The document scrolls to the list of errors at the bottom: The error list is a useful way to get an idea of what sort of errors are in the document.
11	Double-click on one of the ⌧ flags to the left of an error description.	The document scrolls and the cursor is placed next to the error.
12	Rest your mouse on one of the ⌧ flags to the left of an error.	A description of the error pops up:
13	Correct some of the errors - for example, by adding some text to the blank cells, or correcting the invalid date. You do not need to delete the ⌧ flag, but it does not matter if you do.	The highlighting remains even when you have corrected an error. Chronolator does not check for errors as you type - this would make it very slow You need to check the tables again to remove highlights from corrected errors.
14	Press Check Tables.	A message is issued saying whether or not any errors were found.
15	Press OK.	Highlighting is removed from the errors you corrected. Any other errors are highlighted.
16	Close SampleTableWithErrorswithout saving changes.	Chronolator checks the document for errors. A message is issued saying whether or not any errors were found.
17	Press OK.	The document closes.

In this exercise, you have:

seen that Chronolator checks an Internal Chronology for errors whenever it is closed
used the Check Tables button to check for errors on demand
seen examples of the errors Chronolator looks for
learned that Chronolator does not check for errors as you type, so you must press Check Tables after correcting them to remove any highlighting
used the error navigation buttons to go from one error to another, or to a complete list of errors
clicked on the ⌧ symbols in the error list to go to where an error is in the document
