I've tried and failed to do this in vba and now I am failing in C#.
Textstyles are nasty beasts when it comes down to it and they can display fairly odd behavior.
If you copyclip some text from a drawing that has a tablestyle using the text's textstyle, the tablestyle comes along for the ride.
I've ran the following code on a few different drawings and while it appears to work a save will bring up the error "Error writing/closing file"
If you try format->Multiline style you get a fatal error.
I can't imagine what Multiline style can have to do with it as there are no linetypes with text loaded
