GetLastError () |
String |
Returns a string value describing the most recent error that occurred in relation to this object. This function is rarely used since an exception is thrown when an error occurs. |
Update () |
Boolean |
Update the current DiagramObject object after modification or appending a new item. If false is returned, check the GetLastError function for more information. |
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. For example:
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;"
