Setting the Size of ToolBar Icons when using Large Icons

You can specify which size icon should be used when the CommandBars.Options.LargeIcon property is set to True. To do this, use the CommandBars.Options.SetIconSize method. Passing in a value of True for the first parameter specifies that the specified size will be used when LargeIcons are displayed. If False, then the largest set of icons added will be used. If you do not supply a larger icon size, then the closest size icon to the one you are trying to display will be "stretched" to the specified size.
