Error Object Foundation Class

Visual Studio .NET 2003
Category Application
Default Catalog Visual FoxPro Catalog\Foundation Classes\Application
Class _error
Base Class Custom
Class Library _app.vcx
Parent Class _custom
Sample ...\Samples\Solution\Ffc\error.scx

Remarks

This class is a generic error handler that works for both object and procedural code. This class is used with an application framework generated by the Application Wizard.

To use, drop the class on a project or form or, from the Component Gallery Item Shortcut Menu, select Add to Project or Add to Form. When you add the class to a form, Visual FoxPro places the class icon on the form. You can then specify the appropriate property values and access its functionality from input and output objects. When you drop the class on a project, you can choose between adding the class or creating a subclass.

See Guidelines for Using Visual FoxPro Foundation Classes for more information on using foundation classes.
