DiagramObject Attributes:

Attribute	Type	Notes	See also
Bottom	Long	Read/Write The bottom edge position of the element.
DiagramID	Long	Read/Write The ID of the associated diagram.
ElementID	Long	Read/Write The ElementID of the object instance in this diagram.
InstanceID	Long	Read The attribute that holds the connector identifier for the current model.
Left	Long	Read/Write The left edge position of the element.
ObjectType	ObjectType	Read only Distinguishes objects referenced through a Dispatch interface.
Right	Long	Read/Write The right edge position of the element.
Sequence	Long	Read/Write The sequence position when loading the object into the diagram (this affects its Z order). The Z-order is one-based and the lowest value is in the foreground.
Style	Variant	Write only (reading this value gives undefined results) The style information for this object.	Setting the Style

DiagramObject Methods

Method	Type	Notes

Setting The Style

The Style attribute is used for setting the appearance of a DiagramObject; it is set with a string value in the format:

BCol=n;BFol=n;LCol=n;LWth=n;

where:

•	BCol = Background Color

•	BFol = Font Color

•	LCol = Line Color

•	LWth = Line Width

The color value is a decimal representation of the hex RGB value, where Red=FF, Green=FF00 and Blue=FF0000

DiagObj.Style = "BCol=35723;BFol=9342520;LCol=9342520;LWth=1;"

The following code snippet shows how you might change the style settings for all of the objects in the current diagram, in this case changing everything to red:

For Each aDiagObj In aDiag.DiagramObjects

aDiagObj.Style = "BCol=255;BFol=9342520;LCol=9342520;LWth=1;"
