After much hair pulling, I decided to try and create a way to update dref pipe networks to match style and object layer of the parent pipe network. I couldn't figure out how to find the file where dref is targeting, so I just manually select the source file. Using ODBX, I can extract structure & pipe styles and layer (atm, it only deals with structures - testing simplicity), but when it iterates through the active drawing, where the dref network resides, it finds a matching part, but cannot apply a different style to the structure. I get nothing but "Error: Member not found".
I am curious, Jeff, if you made any progress with something of the sort.
I have a feeling legacy COM just has a bug that won't allow the user to change the structure style. I even made a simple command to do nothing but collect a list of structure styles in the active drawing and apply one of them to a selected structure.
I've attached all my code, for anyone that may be interested; the "test" command is my failed sync attempt and the "css" command is my testing function to choose a style from a list and apply it to a single selected structure (no error checking).
