SftPrintPreview/OCX 1.0 - ActiveX Print Preview Control

SftPrintPreview.HelpWanted Event

The Help button is clicked.

Syntax

object

A SftPrintPreview object.

HelpName

Specifies which portion of the control requested help.

Comments

The HelpWanted event occurs when the Help button is clicked.

The user can request online help by clicking on the Help button of the Page Setup dialog or by clicking on the Help button of the built-in tool bar.

This event does not occur when the user hits F1 (or similar keys) as these are normally handled by the application.

The WantHelpButton property is used to define whether the Help button is visible on the tool bar.
