Handling Errors During Report Runs Visual Studio 2005 Visual FoxPro 9.0 provides significant enhancements to the process of creating output, including new opportunities to invoke application code during the native Report System's internal data-handling and output-rendering procedures. To adequately provide users with the ability to develop such programs, Visual FoxPro 9.0 also enhances error-reporting and debugging during a report run. This topic covers error-handling features with special significance for reporting, and examines different strategies for handling abnormal conclusions of report runs. Note Application components such as the Report Output Application and Report Preview Application partner with the Visual FoxPro Report System during output processing. They function as factories to provide appropriate object references to the Report Engine. Although these components may trigger errors and require debugging, they are not active during the internal report run, which

to full scale tracing through the program. You should decide according to the elusiveness of the error which method to use. Here is a list of the various debugging techniques: Using show_cgi http://www.foxweb.com/document/debug.htm to View Browser Input Interpretation of Error Messages Returned to the Browser Examination of the Error Log Placement of Informative Status Messages in your Code Using the Trace Window to Step Through your Code Using show_cgi to View Browser Input If you are unsure whether a browser sends the correct values for fields in HTML forms you can change the action of those forms so that they point to the command the internal FoxWeb script show_cgi. This script returns all the information sent by the browser as part of the request, as well as general system information. Although show_cgi does not exist as a separate script file, it can be called just like you would call any other FoxWeb script:


.
. (your form)
. Another way to utilize the command that show_cgi is to call it within your scripts: <%DO show_cgi%> Interpreting error messages Whenever an error occurs in a user program FoxWeb returns to the browser a description of the error that includes the error message, the program in which the error occurred and the line number of the line that caused the error. In most cases this information is enough to help you identify and correct the error. Examining the Error Log In addition to sending an error message to the browser, whenever an error occurs FoxWeb inserts an entry in the error log. The error log contains a wealth of information pertaining to the error, including the name of the program, the name of the calling program, the error number and message, all Server Variables, any existing form fields, the active memory variables at the time of the error, and all open databases and tables. The easiest way to examine the error log is to use the Error Log Viewer. Placing status messages in your code Status messages strategically placed in your code can indicate progress through the program, as well as display the results of expressions including contents of memory variables and fields. Your messages can include the FoxPro function LINENO()
