One of the most powerful features of Visual Basic is its ability to trap all errors, analyze them, and take corrective action. In a well-designed production application, the user should never see any of the default error messages or encounter a code halt when an error occurs. Also, setting an error trap is often the best way to test certain conditions. For example, to find out if a query exists, your code can set an error trap and then attempt to reference the query object. In an application with hundreds of queries, using an error trap can also be faster than looping through all QueryDef objects. To enable error trapping, you use an On Error statement.

The ActiveChart property lets you manipulate the currently selected chart, whether it is an embedded chart or a chart sheet. All of the properties of the chart are available, which means you can change the data points on the chart, the format of the chart, and other attributes. The following example automatically builds a three-dimensional column chart in the SalesByCategory.xls workbook using the existing data and positions it beneath the data source, as shown in Figure 6-3.

Use a GoTo lineID clause to establish a code block in your procedure that handles any error. The lineID can be a line number or a label.

Understanding Visual Basic Fundamentals Use a Resume Next clause to trap errors but skip over any statement that causes an error. You can call the Err function in a statement immediately following the statement that you suspect might have caused an error to see whether an error occurred. Err returns 0 if no error has occurred. Use a GoTo 0 statement to turn off error trapping for the current procedure. If an error occurs, Visual Basic passes the error to the error routine in the calling procedure or opens an error dialog box if there is no previous error routine. In your error handling statements, you can examine the built-in Err variable (the error number associated with the error) to determine the exact nature of the error. You can use the Error function to examine the text of the error message associated with the error. If you use line numbers with your statements, you can use the built-in Erl function to determine the line number of the statement that caused the error. After taking corrective action, use a Resume statement to retry execution of the statement that caused the error. Use a Resume Next statement to continue execution at the statement immediately following the statement that caused the error. Use a Resume statement with a statement label to restart execution at the indicated label name or number. You can also use an Exit Function or Exit Sub statement to reset the error condition and return to the calling procedure.
