Selection.FillStyle Property (Visio)
Returns or sets the fill style for an object. Read/write.
Setting the FillStyle property is equivalent to selecting a style from the Style list in the Fill dialog box (right-click the shape, point to Format, and then click Fill).
Setting a style to a nonexistent style generates an error. Setting one type of style to another type (for example, setting the FillStyle property to a line style) does nothing. Setting one type of style to another type that has more than one set of attributes changes only the appropriate attributes. For example, setting the FillStyle property to a style that has line, text, and fill attributes changes only the fill attributes.
To preserve a shape's local formatting, use the FillStyleKeepFmt property.
Beginning with Microsoft Visio 2002, setting the FillStyle property to a zero-length string ("") causes the master's style to be reapplied to the selection or shape. (Earlier versions generate a "no such style" exception.) If the selection or shape has no master, its style remains unchanged.
This Microsoft Visual Basic for Applications (VBA) macro shows how to draw an oval and set its FillStyle property. To run this macro, open a drawing based on the Basic Diagram template.
