Change DiagramObject Background Color in Script

[Drops]

How do I set the background color of a diagram object without changing other style attributes?

From my Scripting book

The Style property contains a semi-colon separated list used for setting the appearance of a DiagramObject. It is set with a string value in the format:
     BCol=<c>;BFol=<c>;LCol=<c>;LWth=<n>;
where
BCol = Background Color BFol = Font Color
LCol = Line Color
LWth = Line Width
<n> is a width and <c> is a RGB value.

So I'd suggest to write only one of the attributes to see if it replaces all (I guess not). But if you need to SQL query the according element, parse it and pass the new attribute list.
