Remarks
Although Visual FoxPro makes it possible for you to skip tracing timer events altogether when debugging, this isn't always an appropriate solution because sometimes the code in timer events is pertinent to what you're trying to debug. Instead, this timer determines whether any of the debugging window is visible and if so, sets a special slow interval.
To use, drop the class on a project or form or, from the Component Gallery Item shortcut menu, select Add to Form. When you add the class to a project, you can choose between adding the class or creating a subclass. When you add the class to a form, Visual FoxPro places an icon on the form. You can then specify the appropriate property values and provide any necessary input and output objects. When you drop the class on a project, you can choose between adding the class or creating a subclass.
