Remarks

This class provides a dialog box that displays, conflicting rows encountered during editing sessions under optimistic buffering. The original, current, and new values are presented for resolution. You can use this class with either row or table buffering.

To use, drop the class on a project or, from the Component Gallery Item Shortcut Menu, select Add to Project. When you drop the class on a project, you can choose between adding the class, creating a subclass, or creating a form. If you choose Create a new form from the selected class, Visual FoxPro displays the Open dialog box so you can specify the name of the form, then creates and opens the form in the Form Designer. You need to SET MULTILOCKS ON and enable buffering.
